Hi mkarimi73!
As you point out, this is a resolve the paradox/except question. So four of the answer choices will revolve the paradox and one will not.
You comment,
Yet, I noticed that A, B, C, and E all mention a comparison between the two groups, as you mentioned. And, these are much better answer choices for the LSAT world.
Yes, in general terms, resolve the paradox questions will in some sense involve two "groups," or more precisely, there will be two statements or phenomena that are in tension with one another. Answers that resolve the paradox have to take both statements/phenomena/sides to be true. Often, an answer choice will explain one side but fail to explain how it and the other aspect can both be true at the same time. In addition, in this question, the stimulus specifically makes a comparison ("The researcher found that, compared to sensitizers, ..."). Thus it's not just the LSAT world in general but can also be seen in this stimulus.
You also ask,
So, what's the proper standard here? Avoid answers that are weakly worded at all costs? Because I have seen previous Paradox questions where the correct answer was a "some" statement, yet I recognize that using such a standard is not applicable to ALL LSAT problems. You have to stay flexible and attack the stimulus on its own terms. I'm not sure what to do here...
The word "some" doesn't make (D) problematic. Just to clarify since you mentioned eliminating this answer choice, (D) is the correct answer. But even if the word "some" were changed to "all," this still wouldn't resolve the paradox that repressors tend to excel in certain respects even though sensitizers are more attuned to their internal states. It might explain how the successes of repressors can be self-reinforcing, but it doesn't connect/compare this to sensitizers. Since this comparison is part of the paradox to be explained, this confirms that it is the correct answer on a resolve/except question.
Finally, you seem to provide the right counsel yourself: "stay flexible and attack the stimulus on its own terms." It's good in general to note language like "some" and note when this language indicates weakness, but the particular role and relevance of such language will depend on the stimulus, question stem, and answer choices.
