VERBAL AND LOGICAL ABILITY
|ANSWER KEYS XAT 2015 - SET B
|VERBAL AND LOGICAL ABILITY
1. (C) Para Jumble question - The key links are : first of all QP (why? The Pundits predict doom … But there are optimists) and then PS (But there are incorrigible optimists… … they say... Who says? “They”). Further, S6 must come together. Now we see the connection as QPS6. So what’s left is option (C) → 1RQPS6. Also, statement R is the best explanation of why the world of cinema baffles critics, hence it should follow 1.
[ This question was excellently made, and many students got confused with option (E). ]
2. (D) Vocabulary based question - The term ‘childlike’ is used to describe an innocent person / attitude. However, childish is a term of disapproval. Rest all four options (infantile (behaving childishly), charlatan (quack), imbecile (mentally unfit) and awful (bad)) are all negative.
3. (B) Para Jumble question - This is a tough one, if you do not spot the links easily. The first key link is I – III. Why? Because III says “The reviewers, by contrast…” So we have a contrast with the Critics, who appear described in I. Hence I-III is a key link. Check options now. Eliminate options (A), (C) and (E). Now, the second key link is III – II. Why? Because III mentions “… come close…” and II mentions “… but not close enough …”. Hence the best answer is (B) → IV-V-I-III-II.
4. (A) Logical completion of idea question - The last sentence of the para mentions “the Universe has not been eternal … etc.”. The idea in (A) best completes this key sentence (thought). Option (B) is patently wrong. Option (C) is wrong because the passage says that religion is not saying the correct thing. Option (D) is unrelated. Option (E) is contradictory to the para. Hence (A).
5. (B) Logical completion of idea question – It is clear that options (A), (D) and (E) are wrong. (A) is just a repetition of fact mentioned. (D) is unrelated. (E) is wrong. Now between (B) and (C), we find both are pretty close. So how to choose? (C) is wrong because Leibniz is nowhere mentioned, so (B) becomes correct.
6. (C) Arguments question – Option (A) is wrong because it would support the argument (poor sportsperson). Option (D) has no material fact given in light of the proposed argument. Option (B) talks of shot-put events, whereas the argument talks about sprinting events. Hence wrong. Option (E) talks about “college” whereas we have a “university” competition. So this option may be partially correct. Let us check (C). It fits in best and weakens the argument the most.
7. (D) Vocabulary based question – Let us see the meanings
I. Cacophonic – harsh, unpleasant noise
II. Cacographic – illegible, bad handwriting
III. Calamitous – big disaster related
IV. Catastrophic – big disaster related
V. Contraindicative – to indicate the inadvisability of a medical treatment
VI. Cataclysmic – causing the end of the world (like this XAT paper!)
Hence, the best option is (D) as it combines III, IV and VI (the synonyms).
8. (C) Fill in the blanks – Best way is to eliminate options. The best FIB for first sentence is “eminent”. Hence, options (B) and (E) are eliminated. Now, the third sentence must carry “imminent (about to happen)”. Hence, option (A) is eliminated. Now, in the fourth sentence, “eminence” is the best fit. Hence final answer is (C).
9. (E) Critical Reasoning question - Here, the passage is an extract from Sigmund Freud’s work titled “The interpretation of dreams”. Here, dreams are overt (for the dreamer) whereas the causes underlying the dreams are covert (hidden and unknown, thereby requiring exploring). Option (E) explains it the best.
10. (C) Fill in the blanks question – this is a tricky one, so let us understand step by step. The (v) blanks cannot have “prescribe” as the court is not allowing the prosecutor’s request (“despite”). Hence, it must take “proscribe” (meaning “to prohibit”). So we eliminate options (A) and (D). Now (ii) cannot take “forged” and hence (B) is eliminated. We are left with (C) and (E). Best is (C) because this is how the sentence will read → “It is implied that the accused had faked separation from all criminal activities by adopting the demeanour of a sanyasi. However, despite repeated requests from the counsel for prosecution, the court has proscribed a lie detector to ascertain the truth.”
11. (E) Critical Reasoning question – Examine carefully. (C) is wrong visibly. (D) is too extreme to be accepted. (A) is not really correct because many other factors may be at work, e.g. talent. By the same logic (B) is ruled out. We are left with (E) which is correct.
RC Passage 1 - Facing death and emerging positively charged to live long
Source : “The Count of Monte Cristo” – Alexandre Dumas
12. (E) It is the most direct question you could expect! Given straight in the passage.
13. (A) It is a direct question. Given straight in the passage (third para, second line).
14. (C) A good question, asking us to find the mood of the protagonist. (A) is wrong because it gives a 0 or 1 type situation and more of a psychological issue. (B) is wrong because (C) is much better. How? The key is “daring”. It indicates a physical act being undertaken, in a dire situation, which needs daring. (D) is wrong because it is too philosophical (… tamaso ma jotirgamay …). (E) is wrong because there is no yearning – just a desire to escape.
15. (A) Just check the passage. Eliminate options. (ii) has to be (d) so we eliminate (D) and (E). (iii) has to be (c) so we eliminate (B). Finally, (A) it is!
RC Passage 2 - Learning and neural circuit development process
Source : Multiple sources, typical brain research material
16. (A) It is the most direct question you could expect! Given straight in the passage (last para, first line). Option (B) is too subjective. Option (C) cannot be inferred. Option (D) contradicts the first para itself. Option (E) is too subjective.
17. (B) I is wrong (refer para one) and that eliminated options (A) and (E). V is obviously wrong, so that leaves us now with the answer we seek, i.e. (B).
18. (E) Options (A) to (D) are neither mentioned nor implied by the passage. (E) best explains the idea behind step-by-step learning contributing to an integrated learning. The proverb “Many a mickle makes a muckle” means that “a lot of small amounts, put together, become a large amount.
19. (B) Option (A) is wrong because nowhere is it mentioned that learning is age-dependent. By the same logic, (C) is also eliminated. Option (D) is ridiculous. Option (E) has an extreme word “always”. Hence (B) is best because there is an implicit assumption that the extra 35 years of age of the father must have endowed him with many more learnings pertaining to the environment than his son would have. Hence, (B).
RC Passage 3 - Behavioural gene presence and dandelion/orchid children in human society
Source : Multiple sources
20. (D) It is the most direct question on this passage. (A) is nowhere mentioned/suggested (‘less numerous’ does not mean ‘insufficient’). (B) is ridiculous (greenhouse??). (C) indicates a “maybe” situation (not specific). (E) has the extreme word “always”. Hence (D) is best (remember “anaesthetized” = “controlled”).
21. (D) Option (A) is wrong because it is against the basic idea of the passage. (B) is wrong (cannot generalize). (C) is giving the entirely wrong picture! (D) is correct. (E) is too broad in its scope (“failures of society”).
22. (A) The word appears in the second para directly. It can be construed to be a vocabulary question, but from the context also, we can get it easily.
23. (A) The case means that Mr.Good may have been either an Orchied or a Dandelion but Mr.Evil has to be definitely a Dandelion. Why? Mr.Evil was self-made and failed 5 yrs after his college education was over. Had he been given a protective environment, he would have been an “Orchid” and an exemplary case of never going wrong. But he failed. And he is self-made. So he is a Dandelion. But, Mr.Good may be of either type because he is morally upright, and that indicates a protective environment (also given), and that could be true for both types. Option (E) looks close, but (A) is better.
RC Passage 4 - Competitive markets, public intervention, economics
Source : “Incentives in Economic Thought”
http://xmlservices.unisi.it/depfid/joomla/iscrizione/materiali/9666/Laffont_Incentives.pdf - Page 17
24. (C) Option (A) is wrong because packaged water is a private good, and hence markets can be efficient. Same logic for (B) and (D). Option (C) best fits the definition of public good as given in the paragraph.
25. (A) The word “panacea” is an extreme and hence is ruled out.
26. (C) Best answer.
RC Passage 5 - Creative thinking and brainstorming
Source : Multiple sources, typical brain research material
27. (E) Option (A) is wrong because the second para is not an example. (B) is wrong because there is no contradiction. (C) is wrong because of the same logic as for (B). (D) is wrong as it is too abstract. (E) is best.
28. (D) Last sentence of the second para says “involvement of people with different perspective enriches the idea generation”. Now, option (D) best captures this thought. (A) is wrong. (B) is also unrelated, hence wrong. (C) seems connected, but is a brave conclusion which we may not derive from as sketchy an input as the second paragraph. (D) is best. (E) is ridiculous as big firms may not at all encourage brainstorming (they may also).
