Why is A correct?

@Shiyi-Zhang, Happy to help. The question says, "That some arguments “never receive institutional imprimatur” (line 23) most likely means that these arguments..." The question is asking us what the author means when she says that some arguments "never receive institutional imprimatur" (line 23). Based on the context, we can figure out what "imprimatur" means. In this paragraph, the author discusses a weakness in the argument that courts only hold institutional authority. She says in lines 20 and 21 that "not all arguments accepted by institutions withstand the test of time," providing an example of institutional authority that does not possess intellectual authority, and then she states that not all well-reasoned arguments receive institutional imprimatur in lines 22-23, which refers to the opposite case (a strong intellectual argument not being accepted by an institution). From this, we can infer that institutional imprimatur basically means institutional consensus. This leads us to (A), which states, "fail to gain institutional consensus." Based on our analysis of the second paragraph, this is exactly what the author means by saying that some arguments never receive institutional imprimatur. (B) says, "fail to challenge institutional beliefs" (B) is wrong because it's possible that these arguments did actually challenge institutional beliefs since they weren't accepted. (C) says, "fail to conform to the example of precedent" The problem with (C) is that precedent is not pertinent to this question, as it is not introduced until the final paragraph of the passage. We're concerned with the second paragraph, with lines 22-23 in particular. (D) says, "fail to convince by virtue of good reasoning" Line 22 tells us that these arguments were well-reasoned. the problem with the arguments isn't that they weren't logically convincing; rather, it's that they were not accepted by consensus. Thus, we can get rid of (D). (E) says, "fail to gain acceptance except by coercion" The problem with (E) is that these arguments were not accepted because of coercion. Coercion is one component of institutional authority; the arguments in question did not gain institutional consensus, so this is why (E) is incorrect. Does this make sense? Let us know if you have any more questions!

Could you elaborate why D is incorrect? I am guessing not logically convincing is not the same as not accepted by consensus, so that is why D is wrong? Am I on the right track? Please clarify and let me know. Thank you
