LSAT Question Complete Explanation

First, let's analyze the passage and summarize the key points. Kay has a principle for voting that can be broken down into two parts:

1. If she disagrees with all other candidates on even more important issues, it's acceptable for her to vote for a candidate whose opinions differ from hers on at least one issue.

2. If she doesn't disagree with all other candidates on even more important issues, it's unacceptable for her to vote for a candidate whose opinions differ from hers on at least one issue.

In the upcoming mayoral election, there is only one issue important to Kay, and Medina shares her opinion on that issue. Since there's only one important issue, Kay either agrees or disagrees with each candidate on that issue.

Now, let's go through the answer choices. The question is a Must Be True (MBT) type, meaning we need to find an answer that follows directly from the given information and Kay's principle.

a) We cannot say for certain that it's acceptable for Kay to vote for Medina or Legrand, as the principle doesn't cover when Kay agrees with a candidate on all important issues. Therefore, this answer choice is incorrect.

b) This answer choice states that it's unacceptable for Kay to vote for Norton and Legrand. Since Kay disagrees with them on the one important issue and doesn't disagree with Medina on even more issues, this follows Kay's principle and is the correct answer.

c) We cannot know whether it's unacceptable or acceptable for Kay to vote for Medina, as the principle doesn't cover when Kay agrees with a candidate on all important issues. Therefore, this answer choice is incorrect.

d) This answer choice is incorrect because we cannot conclude that it's unacceptable for Kay to vote for Medina, and we know that it's unacceptable for Kay to vote for either Legrand or Norton.

e) This answer choice is incorrect because it's unacceptable for Kay to vote for either Legrand or Norton, as they disagree with her on the one important issue and don't meet the conditions of her principle.

So, the correct answer is (b): the only unacceptable courses of action are for Kay to vote for Norton and for her to vote for Legrand.
