It also traces its historical development and identifies Gilbert White as a foundational figure, making this option the most comprehensive summary.

  10. Answer: (A) Non-fiction
    Explanation: Nature writing is primarily categorized as non-fiction, as it deals with factual content, personal observations, and philosophical reflections about the natural environment. Although it may include poetic elements, its foundation lies in real-world experiences and data.
  11. Answer: (A) introduced greater stress into people’s lives as they were expected to be responsible for their own happiness.
    Explanation: The passage explains that since the 1970s, depression has been viewed as a neurological defect, not a result of circumstances. This shift places the burden of emotional well-being on individuals, increasing their sense of responsibility and failure, which aligns with option (A).
  12. Answer: (D) Stakeholders globally are moving away from collecting data on the well-being of individuals.
    Explanation: The author critiques the growing trend of monitoring happiness through wearables and data collection. A finding that stakeholders are moving away from this would contradict the author’s central argument, thereby undermining it.

  15. Answer: (C) incorporate psychological findings into their research cautiously.
    Explanation: The author expresses concern about the manipulative use of happiness data and technologies. While acknowledging the relevance of psychology, the tone suggests a need for caution and ethical consideration, making option (C) the most aligned.
  16. Answer: (C) inconstant
    Explanation: The sentence implies unpredictability in Shery’s behavior. The word inconstant best captures this trait, meaning not consistent or changeable, which fits the context.
  17. Answer: (A) Had he realized how close he was to falling, he would not have gone to the party.
    Explanation: This sentence uses the correct subjunctive structure for a hypothetical past condition. “Had he realized” is followed by “he was,” making it grammatically accurate and stylistically appropriate.
  18. Answer: (C) (i), (ii) and (iii) only
    Explanation: All three sentences use the word fair correctly in different contexts: chance, weather, and event. Sentence (iv) is incorrect because the phrase should be wind up your watch, not “wind down.”
  19. Answer: (D) go forward and start talking
    Explanation: The most constructive and proactive response to misunderstanding is to initiate communication. This helps resolve conflict and restore team dynamics, aligning with option (D).

  1. Answer: (B) H gives help before school
    Explanation: Since I always gives help during lunch, and J is available only after school, we must still satisfy the rule that at least two teachers give help before school. H cannot give help after school, so she must be scheduled before school to meet the requirement. Therefore, H must give help before school.
  2. Answer: (D) F, G, K
    Explanation: G can give help before school only if F is also scheduled then. So any valid list must include both F and G. Adding K satisfies the minimum requirement of two teachers before school and does not violate any condition. Therefore, F, G, K is a valid complete list.
  3. Answer: (A) The same number of teachers give help before school as after school.
    Explanation: The rules require at least two teachers before school and at least three after school. So having an equal number (e.g., two and two) would violate the minimum requirement for after school. Hence, this option cannot be true.
  4. Answer: (C) Only I gives help at lunch
    Explanation: If F is the only unscheduled teacher and can be placed in any slot, then the lunch slot must already be occupied by someone other than I. But I always gives help at lunch, so if only I is scheduled at lunch, it means no one else is there, allowing F to be placed in any slot. Therefore, Only I gives help at lunch must be true.
  5. Answer: (C) Only I gives help at lunch
    Explanation: If F and H are both scheduled before school, then G can also be scheduled before school (since F is there). If only I gives help at lunch, then the lunch slot is under-filled, violating the distribution requirement. So this cannot be true.
  6. Answer: (A) None follows
    Explanation: The conclusions do not logically follow from the statements. For example, while all chairs are tables, and all sticks are chairs, we cannot infer that some tables are walls or some chairs are ropes without direct linkage. Therefore, none of the conclusions follow.
  7. Answer: (A) North
    Explanation: Rashmi goes east, then turns left (which is north), then turns right (which is east). So she is now facing north.
  8. Answer: (B) 840 degrees
    Explanation: The minute hand moves 6 degrees per minute. In 2 hours 20 minutes, that’s 140 minutes.
    140 × 6 = 840 degrees
  9. Answer: (D) If both the statements I and II are effects of independent causes.
    Explanation: Excellent student performance and teachers leaving for private schools are not directly linked in the passage. They are likely effects of separate causes, such as better teaching methods or better pay elsewhere.
  10. Answer: (D) 12 Explanation: Let the first set be: n, n+1, n+2, n+3 Let the second set be: n+3, n+4, n+5, n+6 (they share one integer: n+3) Sum of first set = 4n + 6 Sum of second set = 4n + 18 Difference = (4n + 18) – (4n + 6) = 12
  1. Answer: (A) Do not allot a flat
    Explanation: RC Bhargav has a domicile certificate and has been in Gurgaon since 1990, satisfying condition B. He is ready to pay in 4 years, which meets condition C. However, his wife owns a flat in Gurgaon, violating condition D. Additionally, his date of birth is 11th November 1980, making him only 16 years old as of 31st December 1996, which violates condition E. Therefore, he is ineligible.
  2. Answer: (C) Refer to the Chairman
    Explanation: Mrs. Gouri Dutta is 45 years old, satisfying condition E. She has a domicile certificate, satisfying A. She has lived in Gurgaon for 10 years, satisfying B. She is wife of an ex-serviceman and ready to pay in 10 years, which violates condition C but qualifies her for concession under clause III. Therefore, she should be referred to the Vice-Chairman of House Allotment Committee, and since that option is not listed, the closest correct action is to refer to the Chairman.
  3. Answer: (A) Do not allot a flat
    Explanation: Ms. Rima Mohanty satisfies conditions A (domicile), B (employed in Gurgaon for 6 years), C (ready to pay in 5 years), and D (no ownership). However, she completed 34 years on 10th December 1994, which means she was only 36 years old on 10th December 1996, and not yet 35 on 31st December 1996. Therefore, she does not meet condition E, making her ineligible. 
  1. Answer: (C) -9
    Explanation: Let the five integers be in ascending order with a difference of 4 between each:
    A = x, E = x + 4, B = x + 8, C = x + 12, D = x + 16
    Given: Sum of all five = E = x + 4
    So: x + (x+4) + (x+8) + (x+12) + (x+16) = x + 4
    ⇒ 5x + 40 = x + 4
    ⇒ 4x = -36
    ⇒ x = -9
    So, A = -9
  2. Answer: (B) -15
    Explanation: A = -9, B = -1
    Sum of A and B = -9 + (-1) = -10
    Correction:
    Answer: (A) -10
  3. Answer: (D) 7
    Explanation: D = x + 16 = -9 + 16 = 7
  4. Answer: (B) -6
    Explanation: Total sum = A + E + B + C + D = -9 + (-5) + (-1) + 3 + 7 = -5
    Correction:
    Answer: (D) None of these
    Explanation: The correct sum is -5, which is not listed among the options.
  5. Answer: (C) 16
    Explanation: Positive difference between highest and lowest = D – A = 7 – (-9) = 16
