Cannot Be True—SN. The correct answer choice is (B)
The stimulus in this problem contains a set of interrelated conditional statements:
- GS = good student
LM = learn more than what their parents and teachers compel them to learn
DP = derive pleasure from the satisfaction of their curiosity
CC = capable of concentrating on a topic so intently that one loses track of one’s own identity
1. First sentence: GS LM
2. Second sentence, first part: LM DP
3. Second sentence, second part: DP CC
Chain of all statements: GS LM DP CC
Remember, when you encounter Cannot Be True questions featuring conditional relationships, actively seek the answer that violates the precept that when the sufficient condition occurs the necessary condition must also occur. In this problem, that situation is found in answer choice (B).
Answer choice (A): This answer describes a situation where the necessary condition in the second part of the second sentence occurs and the sufficient condition does not. Since the occurrence of the necessary condition does not make the sufficient condition occur, this scenario could happen and this answer is therefore incorrect. This type of answer is a frequent wrong answer in Cannot Be True questions featuring conditional relationships.
Answer choice (B): This is the correct answer choice. The chain of statements in the stimulus shows that every good student derives pleasure from the satisfaction of their curiosity. Thus, it cannot be true that “Most good students do not derive pleasure from the satisfaction of their curiosity.”
Answer choice (C): Like answer choice (A), this answer describes a situation where the necessary condition occurs and the sufficient condition does not. This time the scenario references the relationship in the first sentence.
Answer choice (D): The stimulus only offers information about good students; no information is given about people who are not good students. Accordingly, we can make no judgment about these individuals, and the answer is incorrect.
Answer choices that offer groups that do not meet the sufficient condition are also popular wrong answers in Cannot Be True questions featuring conditional reasoning.
Answer choice (E): Like answer choices (A) and (C), this answer describes a situation where the necessary condition occurs and the sufficient condition does not. Unlike those two answers, you must rely on your understanding of the chain of all statements in order to understand why this answer is possible. Because the “capable of becoming so absorbed in a topic that they lose track of their own identities” is the necessary condition for being a good student, it is possible that most people who meet this condition are still not good students. Again, avoid Mistaken Reversals!
Overall, Cannot Be True questions appear infrequently but they can be troublesome because of their unusual information structure. Whenever you encounter a Cannot question, focus on searching for the answer that cannot follow or the answer that is disproved by the stimulus.
