Must Be True—PR. The correct answer choice is (A)
The author of this stimulus presents the conclusion in the first sentence, followed by the premise, which is introduced with the common premise indicator, “since”:
- Premise: Paying attention to how one reacts to challenge can provided useful insight into ones weaknesses.
Conclusion: Challenge can be an important source of self-knowledge.
In abstract terms, the principle here is something along these lines:
Challenges are good, because paying attention can teach you about your weaknesses.
Since the question asks for the answer choice which most closely conforms to this principle, the correct answer choice should reflect insight as a positive aspect of challenge.
Answer choice (A): This is the correct answer choice. In this case, the referenced challenge is the memory lapse, and the author points out the positive point that this challenge can help the pianist to understand why it happened (gain insight into his or her weakness), and be better prepared.
Answer choice (B): This answer choice lacks both the challenge and the insight necessary to conform with the principle from the stimulus.
Answer choice (C): Like incorrect answer choice (B) above, this choice lacks both the challenge and the valuable insight it can provide.
Answer choice (D): This answer choice also fails to reflect the challenge referenced by the principle in the stimulus, as well as the insight provided by that challenge, so this answer choice cannot be correct.
Answer choice (E): While this answer choice does contain the necessary challenge, and some of the value of taking on that challenge, it lacks the notion of self-insight as a positive aspect of challenge, thereby failing to conform to the principle from the stimulus.
