I initially chose answer choice D while also noting the correlation=/=causation flaw. But I thought that the larger flaw in reasoning was applying the conclusion from an unrepresented sample of "certain personality disorders" to the broader "personality disorders," not just the certain ones. I have since looked again and realized that the "certain personality disorders" were part of the premise and not the Researcher's data. While a flawed comparison, I do not believe it is what answer choice D means.

When going through the answer choices, I didn't altogether rule out answer choice (B) because I logged that it only discussed "cancer-preventive effects", while both studies referred to "cancer or heart disease" and "health of subjects" which I read as not totally resolving the discrepancy in terms of, "well, that's how it is for cancer, what about heart disease?" After reading all of the answer choices, I then chose answer choice (D) because giving half of the subjects a placebo in one study does not resolve why there was NO positive or negative effect, while the other study showed otherwise. It might resolve if the 12-year study supported a DIMINISHED effect. Long story long, answer choice (B) looked like an attractive answer because in my mind it only resolved a portion, while answer choice (D) did not resolve anything.

@lsattsal I start by doing untimed PT/Sections/Drills so I know whether its a matter of understanding. Then, when I have minimized my "understanding" errors, I move to timed sections to try to see what trips me up with limited time. Then, I plan to focus on those things that I need to understand quicker. That's the plan for now, at least! I'm only a couple of weeks in, so everything could be subject to change.

@KatherineBalasa I'm also planning to take the LSAT in June! So far, what I've planned based around my schedule at work, is to spend 2-3 hours after I get home M-Th on lesson plans mixed with light drilling afterward (LR question types first, then RC). I used ChatGPT to roughly provide a syllabus based upon my needs, which I can modify if necessary. Friday is my "flex day" for study: in case I need more, there's 2-3 hours set aside. If not, more time for other things. Saturday is heavy drills or a PT. Sunday is question review and figuring out why what I answered was wrong and how to come to the right answer. I would say it is a PT at least every other Saturday, and I designed it as a 16 week study plan for flexibility to extend. The weeks between my "Study Syllabus" ending and the LSAT will be maintenance... hopefully, but provides additional time if necessary.

That's just how I can learn better, but figured I'd share my process if it helps you!
