I am confused why B is not right? I was focus on the words "Tanner was more persuasive"

    The conclusion is that the survey respondents may have been biased in favor of Lopez. B is incorrect because people in the live audience =/= survey respondents, and even with B the argument could very well still be true, or at best B minimally weakens the argument (how many were in the live audience? 200? How many were surveyed? 1 million viewers? who knows). D, the correct answer, includes the specific group of people we're talking about in the stimulus and includes the modifier "most", which weakens the argument that the audience was biased in favor of Lopez. D is almost like a direct counter premise.

    Thank you!

  • Adding onto to the previous, great answer:
    1) Another reason B is wrong is because the argument that we're trying to weaken is that:
    The audience members surveyed, who tended to think Lopez had the better argument, were inherently biased to favor Lopez to begin with.

    Even if you skipped over the sample population issue of live audience members surveyed vs all debate viewers surveyed, answer choice B tends to conflict with the premise, if you can equate "better arguments" to equal "more persuasive". It definitely does not weaken the argument and I could see how one could argue that it strengthens the argument, if Answer Choice B is saying that a smaller subset of live audience members could see Tanner as more persuasive. Thus, the non-live audience members could be inherently biased for Lopez and the argument still stands.

    2) D is the correct answer because it directly addresses the core assumption in the argument that the audience members were inherently biased in favor of Lopez before the debate began. D flips this on its head, saying that they were instead inherently biased of Tanner, which would absolutely weaken the argument.
