3. Citizen of Mooresville: Mooresville's current city council is having a ruinous effect on municipal finances. Since a majority of the incumbents are running for reelection, I am going to campaign against all these incumbents in the upcoming city council election. The only incumbent I will support and vote for is the one who represents my own neighborhood, because she has the experience necessary to ensure that our neighborhoods interests are served. If everyone in Mooresville would follow my example, we could substantially change the council's membership.

Assuming that each citizen of Mooresville is allowed to vote only for a city council representative from his or her own neighborhood, for the council's membership to be changed substantially, it must be true that

(A) at least some other voters in Mooresville do not make the same exception for their own incumbent in the upcoming election

(B) most of the eligible voters in Mooresville vote in the upcoming election

(C) few of the incumbents on the Mooresville city council have run for reelection in previous elections

(D) all of the seats on the Mooresville city council are filled by incumbents whose terms are expiring

(E) none of the cha1lengers in the upcoming election for seats on Mooresville's city council are better able to serve the interests of their neighborhoods than were the incumbents

答案：A

NN们麻烦解答一下，看了以前的讨论，仍然不明白。多谢！

Just answer the questions: What will happen if the other voters just do what the citizen said? Will the current city council be changed substantively if the other voters follow the citizen's example?

Then answer another question: What is the semantic reference of the phrase 'the same exception for their own incumbent'?

谢谢dphxmg NN，明白了。

ssssss

This is an assumption type of question. There is a hole between premise and conclusion.  All you have to do is fix this hold and make the conclusion firm.

这道题我也有疑问

Kaplan的解释是：the Citizen makes one exception: She’s going to vote for her incumbent, who’s doing a good job. But if everyone in Mooresville did likewise—campaign against incumbents generally but vote for their own incumbent—then no incumbent would lose! To effect the magnitude of change the Citizen desires, then, it has to be true that enough Mooresvillians vote for non-incumbents to throw at least some of the rascals out.

意思是不是说如果大家都投给自己的incumbent，那么总体的incumbent比例并不会变，因为不同的incumbent有不同的人群支持，所以必须要有人投给non-incumbent，才有可能使得the membership to be changed substantially?

谢谢帮忙

This is an assumption type of question; you should first find out what is the conclusion of this argument and use negation technique to test the answer. If weaken the argument after negation then it should be the assumption of the argument.

Assuming that each citizen of Mooresville is allowed to vote only for a city council representative from his or her own neighborhood, for the council's membership to be changed substantially, it must be true that

 (A) at least some other voters in Mooresville do not make the same exception for their own incumbent in the upcoming election

logically “AT LEAST SOME….NOT”’s negation is “SOME”

Negation: SOME voters in Mooresville make the same exception for their own incumbent in the upcoming election.

If some voters support and vote for the one who represents their own neighborhood, the conclusion of this argument --- “substantially change the council's membership” --- can never happen.

This negation weaken the argument. (NOT + WEAKEN) So, this should be the assumption of this argument. A should be the right answer.

(B) most of the eligible voters in Mooresville vote in the upcoming election

(C) few of the incumbents on the Mooresville city council have run for reelection in previous elections

(D) all of the seats on the Mooresville city council are filled by incumbents whose terms are expiring

(E) none of the cha1lengers in the upcoming election for seats on Mooresville's city council are better able to serve the interests of their neighborhoods than were the incumbents
