LSAT Question Complete Explanation

Let's first analyze the passage. Kay has a principle for voting in an election: it is acceptable for her to vote for a candidate whose opinions differ from hers on at least one issue important to her whenever she disagrees with each of the other candidates on even more such issues. In other words, she can vote for a candidate she disagrees with on some issues as long as she disagrees with the other candidates on more issues. Otherwise, it is unacceptable for her to vote for that candidate. In the upcoming mayoral election, there is only one issue important to Kay, and only Medina shares her opinion on that issue.

The question type is Must Be True (MBT), and we are asked to identify which statement must be true about Kay's course of action in any election to select one candidate for a position based on the information in the passage.

Let's analyze each answer choice:

a) If there are no issues important to her, it is unacceptable for her to vote for any candidate in the election.

- This answer choice is not necessarily true, as the passage does not provide information on what Kay does when there are no important issues.

b) If she agrees with each of the candidates on most of the issues important to her, it is unacceptable for her to vote for any candidate in the election.

- This answer choice is not necessarily true, as the passage only discusses what happens when Kay disagrees with candidates on important issues.

c) If she agrees with a particular candidate on only one issue important to her, it is unacceptable for her to vote for that candidate.

- This answer choice is not necessarily true, as Kay's principle allows her to vote for a candidate she disagrees with on some issues as long as she disagrees with the other candidates on more issues.

d) If she disagrees with each of the candidates on exactly three issues important to her, it is unacceptable for her to vote for any candidate in the election.

- This answer choice must be true. According to Kay's principle, she can only vote for a candidate she disagrees with on some issues if she disagrees with the other candidates on more issues. In this scenario, she disagrees with each candidate on exactly three issues, meaning she does not disagree with any of them more or less than the others. Therefore, it is unacceptable for her to vote for any of the candidates.

e) If there are more issues important to her on which she disagrees with a particular candidate than there are such issues on which she agrees with that candidate, it is unacceptable for her to vote for that candidate.

- This answer choice is not necessarily true, as Kay's principle is based on comparing the number of disagreements with each candidate, not comparing the number of agreements and disagreements with a single candidate.

The correct answer is D.
