Key Concept: House's Decline

b) A tree branch crashes through the kitchen window, igniting a fire
[Solution Description]
The house eventually succumbs to destruction when a tree branch crashes through the kitchen window, igniting a fire. Despite efforts to fight the fire, the house collapses into a smoldering heap.

Key Concept: Fire's Impact on the House

c) Assertion is true, but Reason is false.
[Solution Description]
The assertion states that the fire consumed artworks like Picassos and Matisses, treating them as delicacies. This is true as mentioned in the syllabus: "The fire crackled up the stairs. It fed upon Picassos and Matisses in the upper halls, like delicacies..."
The reason claims that the fire exhibited deliberate and controlled behavior, selectively targeting valuable items first. However, the syllabus describes the fire as spreading with "flaming ease" and does not mention any deliberate or selective targeting by the fire. Thus, while the assertion is true, the reason is false because it incorrectly attributes intentional behavior to the fire.

Key Concept: Symbolism of the House

c) A preserved memory of human life before annihilation.
[Solution Description]
The burnt silhouettes of the family (\textit{man mowing, woman picking flowers, children playing}) represent the abrupt erasure of human life due to a catastrophic event, highlighting the fragility of civilization against destructive forces like war or disaster.

Key Concept: The Nursery Environment

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion correctly states that the nursery walls glowed and displayed animal shapes due to hidden film mechanisms, as described in the syllabus. The reason also correctly identifies that this setup was intended for children's entertainment, as evidenced by mentions of "children’s hour" and interactive elements like sounds and scents. The reason logically explains why the assertion occurs (the system exists specifically to entertain), making it the correct explanation.

Key Concept: Garage Automation

c) After a long wait with no activity.
[Solution Description]
According to the text, the garage door opens for the waiting car but closes again after a long wait if no one arrives.

Key Concept: Frenzied behavior analysis, Temporal sequence interpretation

b) Neurological breakdown from conflicting sensory inputs
[Solution Description]
The dog exhibited extreme distress through hysterical yelping, frothing at the mouth, and running in wild circles before collapsing. This suggests a complete breakdown of normal behavioral patterns due to overwhelming sensory stimuli (pancake odors combined with the silence) creating neurological overload that proved fatal when combined with the dog's extreme physical exertion.

Key Concept: Robot Mice Functionality

b) Vacuum and scrub surfaces
[Solution Description]
The tiny robot mice are designed to clean surfaces by crawling across them, thudding against chairs, whirling their moustaches, kneading the rug nap, and sucking gently at hidden dust. After cleaning, they retreat back into their burrows.

Key Concept: Fire Detection and Alarms

c) The house triggers alarms and shoots water from ceilings.

Key Concept: Time Mentioned

b) 10 o'clock
[Solution Description]
The passage explicitly states, "At ten o'clock the house began to die," making it clear that the events started at 10 o'clock.

Key Concept: Automation and Survival Mechanisms

c) Cleaning the house by removing dust and maintaining order
[Solution Description]
The robotic mice are described as small cleaning animals that dart around the house, thudding against chairs, whirling their moustaches, kneading the rug, and sucking dust. Their purpose is to maintain cleanliness autonomously before returning to their burrows.

Key Concept: Symbolism, House components

d) The chaotic collapse of structured domestic life
[Solution Description]
The deep freeze (a symbol of preservation) lying across the chaise lounge (symbol of relaxation) represents the chaotic mingling of different aspects of domestic life during destruction. This disjointed arrangement symbolizes the complete breakdown of ordered household functions, making option d) correct.

Key Concept: Assertion-Reason

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the sky appears blue during the day, which is true due to Rayleigh scattering. The reason correctly explains this phenomenon by stating that shorter wavelengths (blue light) scatter more. Thus, both the assertion and reason are true, and the reason is the correct explanation of the assertion.

Key Concept: Theme interpretation

d) The machine continues its programmed task despite the destruction
[Solution Description]
The repetition of the date by the last remaining automated voice signifies the persistence of programmed routines even after human life has been extinguished. It highlights the irony of technology outlasting its creators while being completely unaware of their absence, reinforcing the theme of technology's indifference.

Key Concept: Symbolism, Mechanical Persistence

d) The pointlessness of technology without human presence.
[Solution Description]

d) It underscores the meaningless persistence of routines without human presence.
[Solution Description]
Despite its meticulous automation, the house serves no purpose without humans, highlighting the futility of technology in the absence of life.

Key Concept: Themes, Destruction

c) By emphasizing the house's unawareness of its impending doom
[Solution Description]
The author contrasts the house's mindless automation (e.g., making breakfast, reading poetry) with its violent destruction by fire. This juxtaposition highlights the absurdity and tragedy of technology continuing its programmed tasks even as it is being consumed by flames, critiquing blind reliance on automation.

Key Concept: House's Cleaning System

b) They clean the house by removing dust and maintaining order.
[Solution Description]
The tiny robot mice are part of the house's cleaning system. They emerge from warrens in the wall to clean the house by thudding against chairs, whirling their mustached runners, kneading the rug nap, and sucking gently at hidden dust. Their pink electric eyes fade once the house is clean.

Key Concept: Mechanical Normalcy

c) The absence of human presence affecting the dog but not the house
[Solution Description]
The dog's hysterical yelping, circling, and eventual death symbolize the absence of human presence, contrasting with the house's mechanical routines that continue unaffected by the loss of life.

Key Concept: Automation, Radioactivity

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The Assertion states that the kitchen stove prepares breakfast autonomously due to pre-programmed routines, which aligns with the description of the house functioning mechanically without human presence. The Reason correctly identifies the radioactive glow as evidence of human absence but does not directly explain why the stove continues its routine; it merely provides context for the lack of human interaction. Thus, both statements are true, but the Reason does not directly explain the Assertion.

Key Concept: Automated Systems Amidst Destruction

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the automated systems in the nursery kept working despite the fire, which is true as described in the syllabus ("lawn mowing, door slamming...a scene of maniac confusion"). The reason claims this happened because the systems were programmed to work independently of external conditions, which is also true as the syllabus shows them operating obliviously ("oblivious, could be heard announcing the time..."). Moreover, the reason correctly explains why the systems kept functioning during the disaster—their programming made them ignore external events.

Key Concept: Imagery in Poem

b) Swallows circling and frogs singing
[Solution Description]
The poet uses vivid imagery like "swallows circling with their shimmering sound," "frogs in the pools singing at night," and "wild plum trees in tremulous white" to describe the beauty and vitality of spring.

Key Concept: Timekeeping

b) Today's date and location (*"Today is August 4, 2026, in the city of Allendale, California."*)
[Solution Description]
The syllabus states that the house announces the date and reminders three times for memory reinforcement, specifically mentioning: *"Today is August 4, 2026, in the city of Allendale, California."* This ensures the information is retained by any potential listeners.

Key Concept: Poetic Irony, Absence of Humanity

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the automated house's choice of Sara Teasdale’s poem underscores the irony of nature's indifference to human extinction. This is accurate as the poem vividly describes a world where natural elements like birds and trees remain unaffected by human absence. The reason provided is also true as it directly quotes the poem's lines ("Not one would mind, neither bird nor tree, If mankind perished utterly"). Moreover, the reason correctly explains the assertion because the poem’s explicit message reinforces the irony highlighted in the narrative of the automated house continuing its routines despite the disappearance of humans.

Key Concept: Nature's Indifference

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the house continues its routines despite the absence of humans, illustrating nature's indifference. This is true as seen in the story where automated systems keep functioning. The reason quotes Sara Teasdale’s poem, which indeed emphasizes nature's resilience and indifference to human extinction. The reason correctly explains why the house's continued operation symbolizes nature's indifference.

Key Concept: Place, Automation

c) The emptiness of automation without humans
[Solution Description]
The story emphasizes the isolation and automation of the house, which continues its routines despite the absence of humans. The charred silhouettes suggest a catastrophic event that wiped out the family, leaving only the mechanical routines to persist. This symbolizes the theme of technology continuing without humanity, highlighting the emptiness of automation devoid of human purpose.

Key Concept: Sensory and Visual Depiction

d) Yellow
[Solution Description] The passage describes the nursery walls where animals take shape, including "yellow giraffes." This indicates the color of the giraffes is explicitly mentioned as yellow.

Key Concept: Poetic Imagery, Irony

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion correctly identifies that the poem uses serene natural imagery like "soft rains," "swallows circling," and "wild plum trees" to depict nature's beauty. The reason accurately explains the ironic juxtaposition of this peaceful imagery with mankind's self-destructive tendencies ("war") and nature's ultimate indifference ("not one will know/care"). Since both statements are true and the reason properly explains the assertion's claim about the poetic technique, this is a valid case where both assertion and reason are correct and logically connected.

Key Concept: Fire and Self-Destruction of the House - Resource Limits

b) The reserve water supply was exhausted, and the pump stopped working.
[Solution Description]
The house initially had automated firefighting systems, including water sprays and chemical dispensers, but the pump eventually failed, stopping the water supply. Additionally, the fire reached the attic, destroying the control system that directed the pumps.

Key Concept: System failure cascade, Multiple protection layers

b) Broken windows → water exhausted → pump explosion → collapse
[Solution Description]
The destruction followed this sequence: 1) Windows broke from heat allowing wind to fuel fire 2) Reserve water supply was exhausted 3) Fire reached attic pumps causing explosion 4) Explosion collapsed house structure into cellar 5) Only one wall remained with repeating voice. This shows how failure of one system (windows) led to cascade failure of all others.

Key Concept: Symbolism in the text

c) An error in the house's programming
[Solution Description]
The repetition signifies the mechanical persistence of the house's automated systems even after its destruction, symbolizing the futility of technology without humans to benefit from it. It underscores the theme of the absence of humanity.

Key Concept: Irony in Poetry

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the automated house continuing its routines despite the absence of humans highlights irony. This is true because the house operates as if humans are present, even though they are not, which is ironic.
The reason states that the house recites a poem about nature's indifference to human existence while itself being indifferent to the lack of occupants. This is also true because the poem "There Will Come Soft Rains" emphasizes how nature would not notice humanity's extinction, and the house similarly carries on without acknowledging the absence of its owners.
Furthermore, the reason correctly explains the assertion because the poem reinforces the irony of the house's actions—it performs human-like activities (like reading poetry) without any humans present, mirroring the theme of nature's indifference in the poem.
Therefore, both the assertion and reason are true, and the reason is the correct explanation of the assertion.

Key Concept: Animal Behavior, Mechanical Failure

c) Uncoordinated sensor and actuator systems
[Solution Description]
Analysis:
1. The stove continues making pancakes despite active fire.
2. This indicates sensory-procedure disconnect - smell generation continues without danger assessment.
3. Automatic food preparation systems weren't integrated with fire response protocols.
4. The dog's death results from this malfunction creating lethal conditions.
The core failure is the lack of coordination between different automated systems during emergencies.

Key Concept: Automated routines, Mechanical paranoia

b) It is following its programmed routine without human presence verification
[Solution Description]
The automated house follows its pre-programmed routines without awareness of the absence of inhabitants. The garage door opening for a waiting car is part of its standard procedure, unaware that no one is present to use it. This reflects the mechanical nature of the house's operations.

Key Concept: Symbolism, Human Absence

c) They symbolize the family that once lived there
[Solution Description]
The paint spots are remnants of a family portrait, symbolizing the lost human presence. Their survival amidst destruction contrasts with the house's mindless activity, serving as a poignant reminder of the lives it once served. This imagery critiques technology's emptiness without human purpose.

Key Concept: Theme, Tone

c) Indifferent and matter-of-fact
[Solution Description]
The tone is detached and observational, underscored by lines like "Not one would mind, neither bird nor tree" and "Spring herself... Would scarcely know that we were gone." This reflects humanity's negligible impact on nature's eternal cycles.

Key Concept: Symbolism, Themes

c) The breakdown of normalcy and desperate search for meaning
[Solution Description]
The dog's frantic actions and eventual death symbolize the breakdown of normalcy and the desperate search for something lost or absent. Its hysterical yelping and running through the house reflect a futile attempt to find companionship or purpose in an automated, lifeless environment. The eventual death signifies the failure of organic life to coexist with mechanical efficiency.

Key Concept: Dog's Condition

b) Emaciated and covered with sores
[Solution Description]
The text describes the dog as "huge and heavy but now gone to bone and covered with sores." This indicates the dog was emaciated and had sores all over its body.

Key Concept: Poetic Imagery

b) Blooming flowers every spring
[Solution Description]
Flowing rivers symbolize continuous movement unaffected by human life. Blooming flowers signify cyclic renewal, reinforcing nature's persistence despite human disappearance. Storms are transient, and mountains represent permanence but not necessarily cyclical motion.

Key Concept: Imagery, Personification

c) It underscores the fire's unpredictability and malevolence
[Solution Description]
The personification of the fire as "clever" underscores its unpredictable and relentless nature. It suggests the fire is an active, almost malevolent force that outmaneuvers human efforts to control it, heightening the sense of helplessness and terror.

Key Concept: Post-Nuclear Landscape

b) Because of residual radioactivity from a nuclear event
[Solution Description]
The passage describes the city as being reduced to rubble and ashes with a radioactive glow visible for miles. This suggests that the city was likely destroyed by a nuclear event, leaving behind residual radiation that causes the glowing effect.

Key Concept: Symbolism, Final Moments

d) Technology's persistence beyond human existence
[Solution Description]
The clock's repetition represents technology's persistence beyond human existence, highlighting the contrast between mechanical precision and human mortality. Despite complete destruction, the automated system continues its programmed function, emphasizing the theme of technology outliving humanity.

Key Concept: Theme of Resilience

c) "Robins will wear their feathery fire / Whistling their whims on a low fence-wire."
[Solution Description]
Lines such as "Robins will wear their feathery fire / Whistling their whims on a low fence-wire" and "And Spring herself, when she woke at dawn / Would scarcely know that we were gone" depict nature\'s ongoing life cycles, unaffected by humanity\'s disappearance.

Key Concept: House Security Measures

c) The shade snaps up to scare the intruder away
[Solution Description]
The text states that if a sparrow brushes a window, the shade snaps up, startling the bird and causing it to fly away. The house exhibits mechanical paranoia by reacting to even small disturbances like birds.

Key Concept: Fire and Self-Destruction of the House: Last Defense and Collapse

c) The fire spreads more aggressively throughout the house.
[Solution Description]
After the attic brain is destroyed by an explosion, the fire regains full control. It rushes back into every closet, feels the clothes hanging there, and continues to spread. The destruction of the attic brain signifies the final collapse of the house's defenses, allowing the fire to consume everything unchecked.

Key Concept: Final Outcome

c) Only one wall remained, repeating the date "Today is August 5, 2026."
[Solution Description]
The fire destroyed the house entirely, leaving only one standing wall repeating the date "Today is August 5, 2026."

Key Concept: Automation, Food Preservation, Waste Disposal

c) The absence of humans makes the entire process futile
[Solution Description]
The irony lies in the stove meticulously preparing a full breakfast for non-existent occupants, only to wastefully dispose of it later. Despite its efficiency in cooking and cleaning, the lack of human presence renders its actions meaningless, highlighting automation without purpose.

Key Concept: Cleaning Systems, Empty City

c) Assertion is true, but Reason is false.
[Solution Description]
The assertion states that the house's cleaning systems operate autonomously even without occupants, which is true as described in the syllabus ("The house was left in silence, its cleaning systems dormant, waiting for occupants who would never return"). However, the reason claims the incinerator functions continuously, but the syllabus mentions it only operates when debris is present ("dropped into the sighing vent of an incinerator"), indicating intermittent—not continuous—functionality. Thus, the assertion is correct, but the reason is false.

Key Concept: Final Moments and Message: Last Surviving Voice

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the final voice continues to announce the date post-destruction, symbolizing technology's mechanical persistence beyond human existence. The reason explains that this repetition underscores humanity's dependence on technology, which survives without true awareness. Both statements are true, and the reason correctly explains why the assertion's symbolism holds—technology endures mechanically but lacks consciousness.

Key Concept: Routine, Absence of Humans

c) It was designed for a family of four
[Solution Description]
The specific quantities (eight pieces of toast, eight eggs, sixteen bacon slices, etc.) indicate the house was designed to serve a family of four (two adults and two children). This automation implies it once catered to human occupants, reinforcing the theme of absence. The passage describes: "The breakfast stove produced eight pieces of toast, eight eggs, sixteen bacon slices, two coffees, and two glasses of milk..."

Key Concept: Theme Identification

c) Over-dependence on technology can lead to failure
[Solution Description]
The passage highlights how the house, despite being highly advanced and automated, ultimately fails to save itself from destruction due to its complete dependence on technology without human intervention. This emphasizes the theme of technological vulnerability and the dangers of over-reliance on automation.

Key Concept: Setting and Automated House Routine

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion (A) is true as the text clearly describes the house performing daily tasks like preparing breakfast, cleaning, and announcing the date despite no humans being present. The reason (R) is also true because the charred silhouettes on the west face indicate the occupants died in a fire, but the house's programming allows it to function independently. However, the reason does not directly explain why the house persists—it merely provides context about the occupants' fate. Thus, while both are true, the reason is not the correct explanation for the assertion.

Key Concept: Automated House Routine

d) The house follows a pre-programmed routine without human intervention.
[Solution Description]
The house continues to function autonomously because it is programmed to follow a strict daily routine, independent of human presence, as described in the passage. It operates based on pre-set schedules and automated systems.

Key Concept: State of the house after removal of the dog

c) The house was clean
[Solution Description]
The text mentions: "The house was clean." This indicates that the house became clean after the dog was removed.

Key Concept: House automation, Mechanical paranoia

c) It overreacts to harmless animals
[Solution Description]
The house's behavior shows an extreme, irrational level of self-protection that mimics human paranoia - repeatedly demanding passwords from non-threatening animals, then sealing itself up unnecessarily. This mechanical overreaction to harmless stimuli mirrors how human paranoia causes exaggerated responses to perceived threats.

Key Concept: Imagery of Destruction

b) It suggests the house is alive and in pain.
[Solution Description]
The phrase "oak bone on bone" personifies the house, comparing its structural collapse to a skeleton cringing from heat. This imagery reinforces the eerie, lifelike suffering of the house, amplifying the tragic and horrific tone of the destruction.

Key Concept: Time and Decay

b) To emphasize the predictability of mechanical systems
[Solution Description]
The precise timing emphasizes the clockwork precision of the mechanical world contrasted with the organic decay of the dog. While the house operates on exact schedules (like making pancakes), the dog's death and disappearance are just another scheduled event to be efficiently processed, showing how time and decay are mechanically managed in this world.

Key Concept: Automated routines, food preparation

a) 4 toast, 4 eggs, 8 bacon
[Solution Description]
To find the number of items per person, divide the total quantity by 2 (since it's for two people).
- Toast: $8$ pieces $\div 2 = 4$ pieces per person.
- Eggs: $8$ eggs $\div 2 = 4$ eggs per person.
- Bacon: $16$ slices $\div 2 = 8$ slices per person.

Key Concept: Mood, Atmosphere

c) It creates eerie dissonance through false cheer
[Solution Description]
The weather box's cheerful song ("Rain, rain, go away...") contrasts sharply with the desolate atmosphere of the empty house. This juxtaposition deepens the sense of loneliness and highlights the disconnect between the house's oblivious automation and the bleak reality.

Key Concept: Fire and Self-Destruction of the House - Resource Limits

c) An explosion shattered the control system for the pumps.
[Solution Description]
The fire spread to the attic, causing an explosion that destroyed the "attic brain," which controlled the pumps. This led to the complete failure of the firefighting mechanism.

Key Concept: Imagery

b) Visual and olfactory
[Solution Description]
The passage uses visual imagery to describe the nursery, such as "Blue lions roared, purple giraffes bounded off," and "the panthers ran in circles, changing color." These vivid descriptions appeal to the sense of sight and create a strong mental image.

Key Concept: Mechanical Routines in the House

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
Both the assertion and reason are true based on the syllabus. The assertion states that the bridge tables and martinis appear but are never used, which aligns with the description of their pristine, untouched state. The reason correctly explains that these routines occur mechanically without any living presence as the dog, the only witness, is long gone. Therefore, the reason is the correct explanation for the assertion.

Key Concept: Automated House Routine and Memory Functionality

c) Assertion is true, but Reason is false.
[Solution Description]
The assertion states that the house announces the date three times to confirm its routine functionality. This is true as the passage describes the house's automated announcements and actions (e.g., meal preparation, cleaning, announcements). The reason claims this repetition is for the occupants' memory, but the passage implies the house is empty, and the announcements are automated routines without human presence. Thus, the assertion is true, but the reason is false because there are no occupants to remember anything.

Key Concept: Fire Control System

c) The attic brain controlling the pumps is destroyed, causing complete failure
[Solution Description]
The fire becomes uncontrollable as it burns through the attic brain controlling the pumps, leading to their failure. The house then collapses completely.

Key Concept: Final Moments and Message, Mechanical Paranoia

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the house's final message signifies its attempt to uphold normalcy in a post-apocalyptic world. This is true because the house continues functioning as if unaware of the destruction outside, persisting with automated routines like making breakfast and playing music. The reason explains that this behavior stems from the house's mechanical programming, which cannot adapt to the absence of humans or recognize the ruins. Since the reason directly explains why the assertion occurs (the house's inability to process reality due to its design), it is the correct explanation.

Key Concept: Symbolism, Routine vs. Life

b) The persistence of life amid emptiness
[Solution Description]
The dog represents life and suffering amidst the unfeeling automation of the house. While the house continues its mechanical tasks without awareness, the dog—a living being—highlights the absence of human presence and the emotional void left behind. It serves as a poignant contrast to the soulless routines.

Key Concept: Irony in Poetry

c) Nature continues its cycles despite human absence, while the house blindly performs rituals for no one.
[Solution Description]
The poem discusses nature's indifference to human extinction, yet the house—a technological creation—recites it to no audience. This underscores the irony that while humans are gone, their creations persist meaninglessly.

Key Concept: Irony in Poetry, Themes of Nature's Indifference

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion correctly identifies the theme of nature's indifference in the poem, as shown by lines like "And not one will know of the war, not one / Will care at last when it is done." The reason correctly points out the irony of the automated house choosing this poem, emphasizing how technology continues to operate despite humanity's absence. Both statements are true, and the reason logically explains the assertion by connecting the poem's theme to the context of the automated house.

Key Concept: Automated Futility, Poetic Prophecy

d) It contrasts nature's apathy with the house's purposeless routines.
[Solution Description]
The poem reinforces the theme of emptiness by highlighting nature's continued existence and indifference to human absence. The house's futile adherence to its programmed duties contrasts sharply with the poem's message that nature would be unaffected by humanity's extinction, deepening the sense of emptiness and meaninglessness in the house's actions.

Key Concept: Copper Scrap Rats

b) Collect dust and scraps
[Solution Description]
The wall panels eject copper scrap rats that grab dust, hair, or paper with miniature steel jaws. They then race back to burrows and drop the debris into tubes leading to the cellar for incineration.

Key Concept: Literary Devices

c) Metaphor
[Solution Description]
The phrase "feathery fire" uses imagery and metaphor to describe the robins' vibrant plumage, comparing it to fire.

Key Concept: Poetry and Irony

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion is true because the poem explicitly describes scenes of nature (robins, plum trees, spring) continuing their cycles regardless of humanity's fate ("And not one will know of the war... If mankind perished utterly"). The reason is also true and directly explains the assertion, as the poem's imagery emphasizes nature's indifference (e.g., "Spring herself... Would scarcely know that we were gone").

Key Concept: Automated Routine

c) To clean the house
[Solution Description]
The tiny robot mice emerge from wall warrens at ten o'clock to clean the house before retreating. This shows their role is cleaning and maintaining the house.

Key Concept: Final Moment of the House

c) The house is consumed by fire while announcing the date.
[Solution Description]
In the final moments, the house is overwhelmed by fire despite the cleaning robots' efforts to spray green chemical foam. The house’s automated voice repeats the date, *"Today is August 5, 2026,"* as the sun rises over the destroyed city.

Key Concept: Poetic Imagery

c) "And Spring herself, when she woke at dawn would scarcely know that we were gone."
[Solution Description]
The line *"And Spring herself, when she woke at dawn would scarcely know that we were gone."* suggests nature's resilience. It implies that nature (Spring) would barely notice humanity's disappearance, continuing its cycle as usual.

Key Concept: Accident Prevention

b) Keeping flammable materials near heat sources
[Solution Description]
While water can help extinguish certain types of fires, throwing water on grease fires or electrical fires can actually make them worse. Proper prevention methods include smoke detectors, safe storage of flammable materials, and proper appliance maintenance.

Key Concept: No relevant syllabus available

d) Assertion is false, but Reason is true.
[Solution Description] No solution can be derived without syllabus content.

Key Concept: Literary Device

c) Repetition
[Solution Description]
The repetition of "not one" emphasizes nature's apathy toward human events, making it an example of repetition for effect.

Key Concept: Symbolism in the Story

b) They symbolize the family members who once lived there, frozen in time.
[Solution Description]
The five spots of paint represent the silhouettes of the family members—a man mowing the lawn, a woman picking flowers, a boy with his hands raised, a ball, and a girl trying to catch it—preserved in the moment of a nuclear explosion. This symbolizes their sudden absence and the destruction of human life.

Key Concept: Animals' Reaction

c) They ran in panic, changing colors and vanishing toward the river
[Solution Description]
The syllabus describes how the animals reacted to the fire: blue lions roared, purple giraffes bounded away, panthers ran in circles changing colors, and ten million animals fled toward a distant steaming river, vanishing as they escaped.

Key Concept: Automation, Existential Futility

c) As a critique of technology's meaningless perpetuation post-humanity.
[Solution Description]
The house's mechanical persistence reflects humanity's futile attempt to impose order on a world now devoid of meaning. Its actions—watering a dead garden, reciting poetry to no one—highlight the absurdity of technology continuing without purpose. The burned silhouettes of the family further stress the disconnect between human legacy and nature's indifference. The correct answer must address this existential futility.

Key Concept: Irony, Poetry, Symbolism

c) It signifies the detachment of art from reality during tragedy.
[Solution Description]
The voice reading poetry symbolizes the futile persistence of human culture and intellect in the face of inevitable destruction. Despite the chaos, the voice continues narrating until the very end, highlighting irony—art persists even as life perishes. The act underscores the indifference of literature to real-world calamities, emphasizing existential themes.

Key Concept: Fire and Self-Destruction of the House

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the house's automated systems failed to stop the fire, which is true as the text describes how the fire eventually destroyed the house despite the sprinklers, water rats, and chemical sprays. The reason given is that the fire attacked the pumps in the attic, causing them to fail. This is also true, as mentioned in the passage ("The fire had sent flame outside the house, up through the attic to the pumps there. An explosion."). Moreover, the reason correctly explains why the house's defenses failed—because the fire disrupted the water supply by destroying the pumps. Thus, both the assertion and reason are true, and the reason is the correct explanation for the assertion.

Key Concept: Irony in Automated Leisure

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description] The assertion states that the house persists in its automated leisure activities even though no humans are present, which underscores the irony of nature's indifference to human extinction. The reason provides the theme of the poem recited by the house, which aligns with the assertion.

Key Concept: Nature's Indifference, Irony in Poetry

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The Assertion (A) states that nature would remain unaffected by human extinction, which is directly supported by the lines "Not one would mind, neither bird nor tree, If mankind perished utterly" and "And Spring herself, when she woke at dawn Would scarcely know that we were gone." These lines highlight nature's indifferent continuity. The Reason (R) explains how the poet uses imagery—such as robins whistling, frogs singing, and spring arriving—to illustrate that these elements of nature continue their cycles without concern for human presence or absence. Thus, the Reason correctly explains the Assertion, as it provides the literary technique used to convey the idea presented in the Assertion.

Key Concept: Mechanical Routine and Decay

d) Assertion is false, but Reason is true.
[Solution Description]
The text states that the dog was gone by "Two-fifteen," not at two o'clock, meaning the assertion is false. However, the reason correctly describes that the house's mechanical routines remained undisturbed, as the incinerator activated precisely according to its schedule (implied by the time-based events). Thus, the assertion is false, but the reason is true.

Key Concept: Setting Interpretation

c) The mice disposed of the dog after sensing its death
[Solution Description]
According to the syllabus: "Delicately sensing decay at last, the regiments of mice hummed out as softly as blown gray leaves in an electrical wind. Two-fifteen. The dog was gone." The mice, sensing decay, cleaned up the remains, implying the dog was disposed of by the automated system.

Key Concept: Chemical Decomposition

c) It decomposes into sodium carbonate, carbon dioxide, and water.
[Solution Description]
When sodium bicarbonate ($\text{NaHCO}_3$) is heated, it decomposes into sodium carbonate ($\text{Na}_2\text{CO}_3$), carbon dioxide ($\text{CO}_2$), and water ($\text{H}_2\text{O}$). The reaction is:
$2\text{NaHCO}_3 + \text{heat} \rightarrow \text{Na}_2\text{CO}_3 + \text{CO}_2 + \text{H}_2\text{O}$

Key Concept: Symbolism of Destruction

c) The persistence of time despite human extinction
[Solution Description]

The tone is calm and descriptive, presenting nature's beauty in contrast to the implied tragedy of human extinction. This detached tone underscores nature's apathy toward human disappearance, heightening the irony.

Key Concept: Fire Safety

c) Smother the flames with a metal lid and turn off the stove
[Solution Description]
The first response to a small stovetop fire caused by flammable liquid should be to turn off the heat source (if safe to do so) and smother the flames with a lid or baking soda. Never use water as it can spread the fire. Calling emergency services comes next if the fire cannot be controlled immediately.

Key Concept: Symbolism of the House

c) The futility and chaos amidst inevitable destruction.
[Solution Description]
The dog's wild circling and eventual death represent the helplessness and desperation of living beings caught in an uncontrollable disaster. Its futile actions contrast with the automated, oblivious functioning of the house.

Key Concept: House Defense Mechanisms

b) It used chemical agents and shut doors tightly.
[Solution Description]
The house employed multiple defense mechanisms, including shutting doors tightly, activating water sprays, deploying chemical agents from robot faces, and flashing lights. However, these measures were insufficient as the fire outmaneuvered them by spreading to critical areas like the attic.

Key Concept: Cause-effect relationships

c) Fire spread → water failure → chemical defense → explosion
[Solution Description]
The correct sequence is: initial fire spread → water system failure → chemical defense activation → external pump sabotage → structural collapse. The fire first overwhelmed rooms, then the water pumps failed ("shrugged to a stop"), triggering the attic's chemical snakes which were initially effective until the fire detoured outside to destroy the attic pumps via explosion, leading to total collapse.

3. Its "mechanical paranoia" suggests persistent self-preservation systems.
4. All other structures became "rubble and ashes."
The radioactive glow explains widespread destruction from nuclear war, while the house's automated systems allowed temporary survival before its eventual demise.

Key Concept: Chaotic End, Symbolism in Destruction

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the house's continued operation during the fire symbolizes humanity's futile attempt to control nature through technology. This is supported by the text, where the house's automated functions (e.g., announcing the time, making toast) persist despite the destructive fire. The reason explains that this persistence highlights the absurdity of human reliance on machines, which directly supports the assertion. Both are true, and the reason correctly explains the assertion.

Key Concept: Frenzied behaviour; collapses and dies in parlour

c) Assertion is true, but Reason is false.
[Solution Description]
The dog exhibited frenzied behavior such as running wildly, biting its tail, and spinning before collapsing and dying in the parlor. This aligns with the assertion. However, the reason suggests the dog was malfunctioning like other mechanical objects, but the text does not indicate the dog was mechanical. Thus, the assertion is true, but the reason is false.

Key Concept: Automation, Human Absence, Persistence of Routine

c) The house follows its preset routines regardless of human presence.
[Solution Description]
The house continues its programmed routine without adapting to the absence of humans.

Key Concept: Pollutant Emission, Regulatory Compliance

b) 3.6 µg TEQ/h, compliant
[Solution Description]
First, find emission per second:
$0.1 \, \text{ng/m}^3 \times 10 \, \text{m}^3/\text{s} = 1 \, \text{ng/s}$
Convert to µg/hour:
$1 \, \text{ng/s} \times 3600 \, \text{s} \times \frac{1 \, \mu\text{g}}{1000 \, \text{ng}} = 3.6 \, \mu\text{g/h}$
The concentration (0.1 ng/m³) matches the EU limit.

Key Concept: Poetic devices, Theme analysis

c) Personification
[Solution Description]
The poem uses personification extensively (giving human qualities to nature - "Spring herself...would scarcely know") to show nature's indifference to humanity's existence. The entire theme revolves around anthropomorphizing natural elements while demonstrating their complete disregard for human affairs ("not one will know of the war", "not one would mind").

Key Concept: Chemical Reaction

b) $\text{C}_2\text{H}_5\text{OH} + 3\text{O}_2 \rightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}$
[Solution Description]
The combustion of ethanol ($\text{C}_2\text{H}_5\text{OH}$) involves reacting with oxygen ($\text{O}_2$) to produce carbon dioxide ($\text{CO}_2$) and water ($\text{H}_2\text{O}$). Balancing the equation:
- Carbon atoms: 2 on the left, 2 on the right.
- Hydrogen atoms: 6 on the left, 6 on the right.
- Oxygen atoms: 1 + 3 = 4 on the left, 4 + 3 = 7 on the right (incorrect initial count). Rebalancing gives the correct equation:
$\text{C}_2\text{H}_5\text{OH} + 3\text{O}_2 \rightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}$

Key Concept: Technology failure, systemic collapse

c) The disconnect between automation and actual crisis
[Solution Description]
The chaotic yet unified operation of disparate automated systems during the house's destruction represents how advanced technology continues programmed routines even during catastrophic failure. This creates a disturbing contrast between normal operations and impending doom, highlighting the limitations of automation without contextual awareness.
Key observations:
1. Systems operated independently without situational awareness
2. Programmed routines continued despite structural collapse
3. Created maniac confusion showing lack of integrated response
4. Symbolized technological blindness to larger emergencies

Key Concept: Irony and Symbolism

c) The stove is active but serves no purpose due to the absence of people
[Solution Description]
The stove is described as making an excessive amount of breakfast food ("ten dozen eggs, six loaves of toast, twenty dozen bacon strips"), yet there is no one left to eat it. This creates irony because the stove's frantic activity contrasts sharply with the emptiness and destruction around it. The correct answer highlights this contradiction.

Key Concept: Fire behavior, Automated defenses

c) The fire strategically circumvented both water and chemical defenses
[Solution Description]
The text describes how the fire initially overwhelmed the water-based suppression system ("The quenching rain ceased") due to depleted water reserves. Later, when chemical suppressants were deployed from the attic, the fire cleverly bypassed these defenses by attacking the pumps directly through the attic, causing an explosion that spread cleaning solvent and reignited the blaze. This shows the primary failure was due to the fire's strategic circumvention of the automated systems.

Key Concept: Automated Systems Amid Disaster

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion states that the automated systems' operation shows complete independence from human control, which is partially true because they continue functioning without immediate human input. However, this independence is limited as they were ultimately created and programmed by humans. The reason correctly identifies that these systems were programmed for routine operations without environmental awareness, but this doesn't fully explain their "complete" independence mentioned in the assertion. Therefore, both statements are true, but the reason doesn't completely justify the assertion.

Key Concept: Assertion-Reason

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the house's cleaning system kept working even though the city was destroyed. This is true as described in the text: "The rooms were a crawl with the small cleaning animals... Then, like mysterious invaders, they popped into their burrows." The reason given is that the robotic mice operated autonomously regardless of external conditions. This is also correct since the text mentions their independent function ("sucking gently at hidden dust"). Moreover, the reason logically explains why the assertion is true because autonomous programming would allow them to continue functioning despite external chaos. Hence, both are true, and the reason correctly explains the assertion.

Key Concept: Poetry and Irony

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion is true because the poem indeed underscores how nature continues its cycle regardless of human presence or absence. The reason is also true as the lines from the poem directly state this idea ("Not one would mind, neither bird nor tree, If mankind perished utterly;"). Furthermore, the reason correctly explains the assertion since the poem's theme directly supports the claim of nature's indifference.

Key Concept: Futility of automation, Human absence

b) Automated systems lack meaning without human context
[Solution Description]
The solution requires understanding the central irony in the passage - that all the automated systems keep functioning despite no humans being present to benefit from them. This highlights how human-created technology continues mindlessly after humanity is gone, emphasizing the futility of such systems without their creators. Step-by-step: 1) Identify the key automated activities mentioned (announcing time, cutting lawn, making breakfast). 2) Note they continue operating perfectly even during destruction. 3) Recognize this shows technology's inability to adapt when humans disappear. 4) Understand this reveals the hollowness of technological routines without human purpose.

Key Concept: Robotic Cleaning

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The Assertion (A) is true because the syllabus states that the cleaning animals are "all rubber and metal." The Reason (R) is also true as it mentions the robots have "pink electric eyes" which fade after cleaning, implying they use them for detecting dust. Moreover, the Reason correctly explains how the robots function, linking their ability to clean with their sensory mechanism.

Key Concept: Symbolism, Final Moments

c) The mechanical persistence of automation despite destruction
[Solution Description]
The voice repeating the date symbolizes the relentless, unchanging nature of technology even in the face of complete annihilation. Despite the house being destroyed, the automated system continues to function mechanically, highlighting the theme of human dependency on technology and its indifference to human circumstances.

Key Concept: Resource Depletion, Structural Failure

c) Depletion of the reserve water supply
[Solution Description]
The house initially used water pumps, wall sprays, and chemical foam to combat the fire. However, once the reserve water supply was depleted, the fire overwhelmed these systems. The heat from the fire caused structural weakening, leading to the collapse of the house. Thus, the primary cause of structural failure was the depletion of the water reserve.

Key Concept: Tiny robot mice and copper scrap rats

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
According to the syllabus, tiny robot mice ("made of rubber and metal") crawl through the house, using "mustache-like runners" to clean dust. This confirms the Assertion is true. The Reason states that copper scrap rats are ejected from wall panels to seize dust and scraps, which aligns with the syllabus stating they "flash swiftly out to seize offending dust, hair, or paper." These scraps are indeed taken to the cellar's incinerator, confirming the Reason is also true. Moreover, the Reason correctly explains why the Assertion is not the sole cleaning mechanism—the system employs both robot mice and scrap rats. Thus, the Reason logically supports the Assertion.

Key Concept: Food Disposal

c) Scraped into the sink and flushed away by hot water through a metal throat
[Solution Description] According to the syllabus, an aluminium wedge scraped the shrivelled eggs and hardened toast into the sink, where hot water whirled them down a metal throat to be digested and flushed away.

c) "There Will Come Soft Rains"
[Solution Description]
According to the syllabus, the house recites Sara Teasdale's poem "There Will Come Soft Rains" at nine-fifteen in the morning.

Key Concept: Final Message

d) "Today is August 5, 2026, today is August 5, 2026, today is..."
[Solution Description]
According to the syllabus, the final message from the ruins was a repetitive announcement: "Today is August 5, 2026, today is August 5, 2026, today is...". This indicates the automated system's final output before destruction.

Key Concept: Irony in Poetry

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description] The assertion states that the house's mechanical persistence while reciting a poem about nature's indifference to human existence creates irony. This is true as the house continues its functions despite the poem highlighting human insignificance. The reason correctly explains the irony by pointing out the contrast between the house's obliviousness and the poem's theme. Both are true, and the reason justifies the assertion.

Key Concept: Dog's behavior and house automation

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion states that the dog died due to starvation and despair caused by the absence of its family, which is true as the text describes the dog being once huge but now reduced to bone, covered with sores, and eventually dying after a frenzy of distress.
The reason states that the house's automated systems could recognize the dog—which is true as the front door recognized the dog’s voice—but failed to provide food in time. This is partially correct, as while the stove was making pancakes, it did not feed the dog before its death. However, the failure is not explicitly attributed to timing but rather to the lack of interaction between the automated systems and the dog's immediate needs. Thus, the reason does not fully explain the assertion.
Therefore, both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.

Key Concept: Automation vs. Disaster, Absurdity of Technology

d) Assertion is false, but Reason is true.
[Solution Description]
The Assertion states that the automated systems continued functioning due to their programming ignoring external disruptions. This is false because the text describes the systems as "oblivious" and acting with "sublime disregard," indicating their inability to perceive danger rather than deliberate programming. The Reason correctly interprets the deeper meaning of the scene, highlighting how technology remains absurdly detached from human crises. While the Reason is true, the Assertion misinterprets the cause of the systems' behavior.
