Mariah: Joanna has argued that Adam should not judge the essay contest because several of his classmates have entered the contest. However, the essays are not identified by author to the judge and, moreover, none of Adam' s friends are classmates of his. Still, Adam has no experience in critiquing essays. Ttherefore, I agree with Joanna that Adam should not judge the contest. Which one of the following principles, if valid, most helps to justify Mariah's argument? ['A suspicion of bias is insufficient grounds on which to disqualify someone from judging a contest.', 'In selecting a contest judge, fairness concerns should override concern for the appropriate expertise.', 'Expertise should be the primary prerequisite for serving as a contest judge.', "The ability of a judge to make objective decisions is more important than that judge's content expertise."]
