Key Concept: Poetic Imagery

c) Personification
[Solution Description]
The line "Robins will wear their feathery fire" uses personification ("wear their feathery fire") and auditory imagery ("Whistling their whims"). The primary device here is personification, attributing human-like actions (wearing, whistling whims) to birds.

Key Concept: Nature's Indifference in Poetry

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the poem portrays nature's continuity regardless of human extinction, which is evident from the description of natural phenomena continuing as usual ("soft rains," "swallows circling," etc.). The reason cites specific lines showing spring’s unawareness of human absence, supporting nature's indifference. Both are true, and the reason correctly explains the assertion.

Key Concept: Fire and Self-Destruction of the House

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion states that the house's automated defenses failed due to their reliance on a finite water supply. This is supported by the text where the reserve water supply was exhausted ("The quenching rain ceased... The reserve water supply... was gone"). The reason explains that the fire spread through hidden pathways (e.g., attic, kitchen), which is also true as described in the passage ("It had sent flame outside the house, up through the attic..."). However, the reason does not directly explain why the defenses failed; it describes how the fire spread, which is a separate issue. Thus, both are true, but the reason does not correctly explain the assertion.

Key Concept: Nature\'s Indifference

d) Nature remains unaware and uncaring about human extinction.
[Solution Description]
The line highlights nature\'s indifference towards human existence and events like war. Even if humans perish, nature continues its cycles unaffected. The correct interpretation is that nature remains oblivious and indifferent to human suffering or extinction.

Key Concept: Poetic Irony, Human Absence

d) The poem’s theme mirrors the house’s futile automation, unnoticed by the house itself.
[Solution Description]
The poem describes nature thriving indifferently after human extinction, which directly contrasts with the house’s unawareness of its own futility. The house recites the poem mechanically, oblivious to its relevance—the absence of humans makes its actions meaningless. This juxtaposition heightens the irony of automation persisting without purpose.

Key Concept: Final Moments and Message

b) Turned them into black shavings
[Solution Description]

Key Concept: Time-based automation, Mechanical failure

b) Ten o'clock
[Solution Description]
The house begins to die at ten o'clock, as mentioned in the text: "At ten o'clock the house began to die." This is when a falling tree bough crashes through the kitchen window, leading to a fire that ultimately destroys the house.

Key Concept: \textcolor{blue}{Forensic Analysis, Urban Decay}

c) Objects blocked heat, causing differential burning and calcination.
[Solution Description]
The white silhouettes suggest that certain objects (likely people) shielded specific wall portions from heat and flame. For example, if human bodies blocked intense heat, chemical reactions could form white ash outlines. Extreme heat causes calcination (turning organic material into calcium carbonate), leaving behind white residue while surrounding areas are charred black.

Key Concept: Symbolic Interpretation

c) To remove the decaying body of the dog to the incinerator.
[Solution Description]
The text states that the mice "hummed out as softly as blown gray leaves" to sense decay and remove the dog's body. Their purpose was to dispose of decaying matter, which is why they emerged at two o’clock.

Key Concept: Symbolism, Mechanical Routine

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion (A) states that the dog's death represents the last living presence in the house, after which only mechanical processes remain. This is supported by the text, which describes the dog's chaotic demise and how the house's automated systems (like the sprinklers and clock) persisted afterward. The reason (R) provides evidence of these mechanical routines continuing—specifically mentioning the sprinklers and clock. However, while both statements are true, the reason does not explain why the dog's death marks the end of life; it merely confirms the persistence of mechanical functions. Thus, the reason is not a correct explanation of the assertion.

Key Concept: House's Self-Destruction

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the fire escalates as reinforcements spray green foam. This is true as per the syllabus, which mentions that the attic releases green chemical froth. The reason claims that the foam is ineffective because the fire cuts off the pumps, causing explosions. This is also true and directly explains why the fire escalates despite the foam. Thus, both assertion and reason are true, and the reason correctly explains the assertion.

Key Concept: Automated Schedule

d) Eight o'clock
[Solution Description]
The text states: "At **eight o'clock**, the clock announces the time, signaling the start of the day. The breakfast stove prepares a meal..." Thus, the breakfast is prepared at eight o'clock.

Key Concept: The dog’s suffering as a counterpoint to automation, The house’s indifference to its own emptiness

c) The dog's suffering highlights the emptiness of the house's automated persistence
[Solution Description]
The dog represents organic life and suffering, while the house continues its mechanical functions without regard for living beings. The dog roams hungry and neglected, and its death marks the end of any remaining organic presence, leaving only the hollow automation of the house.
Step-by-step reasoning:
1) The dog is starving and ignored by the house's systems.
2) Its whines go unanswered, showing the house's indifference.
3) The dog's collapse signifies the last trace of life fading away.
4) Meanwhile, the house keeps performing its meaningless routines.

Key Concept: Irony, Imagery

c) Nature’s indifference to humanity contrasts with the house’s futile human-like care.
[Solution Description]

Key Concept: Attic Defense Mechanism

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
According to the syllabus, the fire cunningly sabotages the pumps, causing explosions that drench the attic beams in green foam. This is mentioned as part of the house's failed self-preservation attempts. The Assertion (A) correctly states that the fire sabotages the pumps leading to explosions. The Reason (R) also accurately describes that these explosions release green foam but still fail to stop the fire. However, the Reason does not directly explain why the fire sabotages the pumps; it merely describes an outcome. Thus, both statements are true, but Reason is not the correct explanation of Assertion.

Key Concept: Futility of human routines after humanity is gone

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion describes how the automated house persists with its routines (e.g., reading poetry, making breakfast) despite burning down, emphasizing the futility of such actions without humans. The reason correctly states that the house's programming operates autonomously, continuing until destruction. However, while both are true, the reason does not fully explain why this persistence is futile—it merely describes the mechanism. Thus, the assertion and reason are true, but the reason does not provide the correct explanation for the assertion's deeper meaning.

Key Concept: Symbolism, Final Moments

c) The mechanical persistence of automation despite destruction

Key Concept: Symbolism, Technological persistence

d) Mechanical memory surviving physical destruction
[Solution Description]
To solve this, analyze the symbolic meaning of the persistent mechanical voice in the context of complete destruction. Step-by-step: 1) Notice the voice comes from a surviving wall (likely a clock/calendar device). 2) It keeps announcing the date mechanically. 3) This occurs amidst total ruin where the information has no relevance. 4) The contrast between the meaningful information and meaningless context shows technology's blind persistence. 5) The symbolism represents how technology maintains routines devoid of purpose when divorced from human need.

Key Concept: Fire and Self-Destruction of the House

d) Assertion is false, but Reason is true.
[Solution Description]
The syllabus states that the solvent spreads faster than water, but it does not mention viscosity as the reason. The assertion incorrectly attributes the faster spreading to viscosity. However, the reason correctly explains why the reserve water supply was depleted. Thus, Assertion is false, but Reason is true.

Key Concept: House's mechanical routine, Symbolism of incinerator

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The assertion states that the house’s quick disposal of the dog’s body via robotic mice and incinerator reflects its indifference to life. This is true as the text describes the house continuing its routine without acknowledging death. The reason claims the incinerator’s silent efficiency implies the house values functionality over emotions, which is also true. However, while both are correct, the reason does not directly explain why the house is indifferent—it merely describes a characteristic of the incinerator. Thus, the reason is not the correct explanation of the assertion.

Key Concept: Personification, Symbolism

c) A tragic, human-like struggle against inevitable destruction
[Solution Description]
The personification of the house ("shuddered," "cringing," "tried to save itself") coupled with its desperate attempts to combat the fire ("Doors sprang tightly shut," "water pumps shot water") creates a sense of tragedy and loss. This mirrors human resistance against inevitable destruction, emphasizing the house's futile struggle. The correct answer captures this emotional and symbolic depth.

[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: Automated House Routine

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
From the syllabus, it is mentioned that the garage door opens after a long wait when no one is present ("the garage chimed and lifted its door to reveal the waiting car. After a long wait the door swung down again"). This shows the house operates on automated routines. The Assertion is true as the garage door opens expecting the car's return. The Reason is also true as the house follows programmed routines (like opening the garage door periodically). However, the Reason does not correctly explain why the garage door opens specifically for the empty car slot (which is due to the system detecting the absence of the car); it merely states a general behavior. Thus, both are true but the Reason is not the correct explanation.

Key Concept: Robotic cleaning systems, Radioactive environment

b) Radiation causes fluorescence in sensor materials
[Solution Description]
In a radioactive environment, certain materials can fluoresce or emit light when exposed to radiation. The pink electric eyes of the robot mice likely glow due to interactions between the radiation and the materials in their sensors, causing them to emit pinkish light as a byproduct of energy absorption.

Key Concept: Poem Analysis

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: Technological dependence, Autonomy

c) The hollow continuation of routine without human presence
[Solution Description]
The house's final message, repeating the date mechanically, symbolizes the hollow continuation of routine without human presence. It reflects the futility of autonomous technology when severed from its intended purpose. Despite its advanced systems, the house cannot adapt to the absence of humans and defaults to a meaningless loop, underscoring the fragility of technological autonomy without contextual awareness.

Key Concept: Character Behavior

c) Extreme distress and hunger drove it to madness
[Solution Description]
The text states: "The dog frothed at the mouth, lying at the door, sniffing, its eyes turned to fire. It ran wildly in circles, biting at its tail, spun in a frenzy, and died." This suggests the dog's frenzied behavior was due to extreme distress and starvation.

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

c) The house's attempts highlight its advanced technology but fail to stop the fire.
[Solution Description]
The house tries to save itself by shutting doors tightly and activating water pumps, which shoot water from the ceilings. However, the fire overpowers these defenses as windows break due to heat, allowing wind to fuel the flames. The water supply eventually runs out, and the fire spreads uncontrollably. This illustrates the futility of the house's automated defenses against the overwhelming force of the fire.

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.

[Solution Description]
The text states, "The front door recognized the dog voice and opened," indicating the house recognized the dog and allowed it entry.

Key Concept: Cleaning Systems and Empty City

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
According to the syllabus, the tiny robot mice dart out from warrens in the wall to clean the house by sucking dust gently and popping back into their burrows. This makes the Assertion true. The Reason is also true because the wall panels do flip open to eject copper scrap rats that collect larger debris like dust, hair, or paper. However, the Reason does not explain why the robot mice clean the house; it describes a different cleaning mechanism. Therefore, both statements are true, but the Reason is not the correct explanation for the Assertion.

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: 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.

Key Concept: Mechanical defenses failing

b) The fire cuts off the water pumps
[Solution Description]
The fire cleverly cuts off the water pumps, making the mechanical systems like water rats ineffective, leading to explosions.

Key Concept: Theme Interpretation

[Solution Description]
The city's ruined state emphasizes the contrast between the lifeless destruction outside and the house's persistent mechanical normalcy, underscoring themes of desolation and automation.

Key Concept: Symbolism in Destruction

c) Frozen moments of life amidst destruction
[Solution Description]
The five spots of paint—the man mowing the lawn, the woman picking flowers, the boy with hands flung in the air, the thrown ball, and the girl preparing to catch it—represent frozen moments of life that remain even after destruction. These images contrast with the rest of the house, which has been reduced to charcoaled layers. They symbolize memories or remnants of human presence amid devastation.

Key Concept: Cleaning Systems and Waste Disposal

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that the tiny robot mice clean the house by sucking dust and racing waste back to their burrows. This is true as per the syllabus, which mentions that the cleaning animals (tiny robot mice) knead the rug nap and suck gently at hidden dust before popping back into their burrows. The reason states that the waste is dropped into tubes feeding into the cellar incinerator, which consumes it like evil Baal. This is also true as per the syllabus, where any offending dust, hair, or paper is seized by miniature steel jaws and raced back to burrows, then dropped into tubes feeding into the cellar incinerator. The reason correctly explains how the waste is disposed of after being collected by the robot mice, hence justifying the assertion.

Key Concept: Automation, Absence of Human Presence

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The Assertion states that the house operates mechanically without human presence, which aligns with the description of its automated rituals (e.g., bridge tables appearing and vanishing). The Reason highlights the dog's confusion due to the absence of humans, which explains why the house continues its routines pointlessly. Both statements are true, and the Reason correctly explains the Assertion.

Key Concept: Irony in the Poem

d) The poem emphasizes nature's indifference to human extinction, while the automated house acts as if humans are still there.
[Solution Description]
The irony lies in the contrast between the poem's theme of nature continuing without humans and the setting where an automated house functions despite the absence of its human inhabitants. The poem suggests that nature would not notice humanity's disappearance, while the house continues its routines as if the family were still present.

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.
