3. (B)
Question Type: Strengthen the Conclusion
Although Mariah discusses Joanna’s arguments against Adam judging the essay contest, Mariah’s conclusion is actually supported by only one premise _ that Adam has no experience in critiquing essays. To strengthen Mariah’s argument, we want to reinforce the position that Adam’s lack of experience alone makes him a poor candidate to judge the contest. Answer (B) clearly strengthens this connection.
(A) is too narrow in scope. It discusses Mariah’s response to Joanna’s argument rather than discussing Mariah’s actual position.
(C) has problems of degree and contradiction. The argument does not discuss the relative importance of bias and expertise (degree). In addition, since Mariah’s argument depends on lack of expertise being sufficient reason to exclude Adam as a judge, if anything it could be construed that she believes expertise to be more important than objectivity, making the answer choice a contradiction.
(D) restates the logic in (C) and suffers from the same problems of degree and contradiction.
(E) is out of scope. Mariah explains that she believes that Adam has no bias, but her argument does not discuss bias or how it might or might not disqualify a potential judge.
