I really struggled to concentrate with this passage because my college roommate is getting his doctorate in genetics, so I mock him about punnett squares and he tells me crazy shit about how genetics actually works.
Why is #13 E? The passage says nothing about many biologists accepting the new evidence and research that shows genes can be inherrited horizontally. The only time a group of biologists is mentioned in the passage is in the first paragraph, when they reject Lamarck's ridiculous hypothesis and believe environmentally induced adaptations are not genetic. Is this that many=some BS? Because many, to me, indicates a large percentage or general group of people.
IDK if you've checked out manhattan at all but heres the explanation they give on their blog/forum thing
"The word many indicates "at least some." And it is true that many biologists no longer believe that "all genes are inherited vertically." In lines 51-58 the passage says that the evidence appears to show that some genes can be transmitted horizontally. If some genes are transmitted horizontally, then it's not true that all genes are transmitted vertically.
I know you're focused on the term "many biologists." Remember that this is actually a very weak way of referring to biologists. Two biologists no longer holding this view would be enough. And on line 57, the passage implies that these biologists have accepted the claim that some genes are transmitted horizontally.
(A) is on the wrong side of the argument. It appears that more biologists may be inclined to hold this belief.
(B) is on the wrong side of the argument. It appears that more biologists may be inclined to hold this belief.
(C) is not something biologists previously believed. The question is about what biologists "no longer" believe.
(D) is not mentioned in the passage. We know that some biologists believe this claim to be true, but not whether any believe this claim to be false."
