YES- thank you so much for this explanation! Agreed that #admin should revise this explanation

Agreed!! I wish this would have been at the beginning!

Seeking advice on building my recognition that the question is difficult and I should just choose and move on. I know that most of the science questions try to use difficult-sounding subjects to hide logic that is actually straightforward, so I don't want to get in the habit of seeing stimulus like this and writing it off. How much time should I spend before guessing? #help

I use a separate text book for LR studying (power score) and I've had better results. I got a used older addition since I don't need access to the same practice tests.

I did the same! I thought that it was introducing an omitted correlative factors that broke down this assumption that wine intake determines heart disease. I guess a takeaway is that this may weaken the sub-conclusion/ main premise (the relationship between wine and risk of heart disease) but it leaves intact the main conclusion (that heart disease determines overall health). I guess if faced with multiple options for weakening watch out for traps that weaken the main premise instead of main conclusion.
