Whenever she considers voting in an election to select one candidate

Question

Whenever she considers voting in an election to select one candidate for a position and there is at least one issue important to her, Kay uses the following principle in choosing which course of action to take: it is acceptable for me to vote for a candidate whose opinions differ from mine on at least one issue important to me whenever I disagree with each of the other candidates on even more such issues; it is otherwise unacceptable to vote for that candidate. In the upcoming mayoral election, the three candidates are Legrand, Medina, and Norton. There is only one issue important to Kay, and only Medina shares her opinion on that issue.

According to the principle stated in the passage, in the upcoming mayoral election

(A) it is acceptable for Kay to vote for either Medina or Legrand, but it is unacceptable for her to vote for Norton
(B) the only unacceptable courses of action are for Kay to vote for Norton and for her to vote for Legrand
(C) it is unacceptable for Kay to vote for any of the candidates
(D) the only unacceptable course of action is for Kay to vote for Medina
(E) it is acceptable for Kay to vote for any of the candidates

B should be the answer.
Since only 1 issue is important to Kay and Medina is the only one who shares that issue, Medina differs with Kay on 0 issues. On the other hand, the othe 2 individuals differ with Medina on 1 issue. Therefore, it is unacceptable for Kay to vote for the other 2 candidates.

This question is from preptest 26, section 3, number 23.

The OA is B. Below is my reasoning

1) The stimulus states that it is  acceptable  to vote for a candidate whose opinions differ on at least on issue that is important whenever Kay disagrees with each of the other candidates on even more  such  issues. 
2) There is only  one  important issue and only Medina shares her opinion.

Therefore, Legrand and Nortan does not share Kay's opinion on the important issue. This means that it is unacceptable to vote for Legrand or Nortan because they both disagree with her on 1 important issue while Medina disagrees with her on 0 important issues.

I think it is B. When Norton and Degrand did not have any issue, no chance for kay to consider them. Also Medina has a issue and she has atleast 50% chance to disagree with kay's opinion. So option C cannot be the answer.

JSY · Answer

(B) and (D) are somewhat opposites in their answers so it is important to go back and understand the stimulus first. I will see if I can try and explain the stimulus better.

When choosing a candidate, Kay uses the criteria of "important" issues. In this particular case, there is only one important issue to Kay. The principle that the stimulus states is about a world where there is no single candidate that agrees 100% on Kay's important issues. In this world, it is acceptable to then pick a candidate where Kay disagrees with less on an important issue than others. Therefore, the only scenarios where it is unacceptable to vote for any candidates is when she disagrees with everyone equally or there is another candidate where she disagrees with less.

In this particular case, Medina disagrees with her on 0 issues (the optimal scenario for Kay), Legrand and Nortan disagrees with her on 1 issue. Therefore, we know that from the principle stated in the stimulus, it is unacceptable to vote for Legrand and Nortan. However, it  is  acceptable to vote for Medina, that's why (D) is wrong.

Does that clarify between (B) and (D)?

It is mentioned, median shares her opinion NOT 'differs'.

All 3 may equally differ as well, we do not know ! All possibilities exist.
