LSAT 116 | Section 4 | Reading Comprehension: Q23

RC Question 23 Explanation

DISCUSSION: This is tricky. Don’t just look at the answers that talk about wine consumption. Remember that lines 53-60 say that the health benefits of grape juice may help prove that moderate wine drinking is healthy.

___________

1. CORRECT. Lines 50-52 show that moderate wine drinking makes blood vessel inner walls less thick. If drinking grape juice did the same thing, then lines 53-60 imply that wine could be healthy, because of grapes. 
2. This shows no difference between wine and beer drinking. We’re told beer drinking is bad, so how does this help wine?
3. Platelet adhesiveness is bad. This hurts the argument, since wine is made of grapes. (You might think that this answer contradicts lines 53-55, but it doesn’t. Sure, one study showed grapes reduced platelet adhesiveness. But studies often contradict each other).
4. This doesn’t tell us anything new about moderate wine consumption. It’s unclear how this interesting fact about excessive wine drinking strengthens the idea that moderate wine is good.
5. This doesn’t tell us that wine is good. It’s just an interesting genetic fact about some people.
