求助费费的逻辑题,想不通。请大家指教

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

        
答案是A. 主要是把A取非,就能看出是not+削弱。但是还是不能理解这道题。请大家帮忙分析一下。

The hiden information is "Most if not all incumbents have their own neighbor."   If every citizen will vote only for the incumbent from his/her neighborhood, the city council will not be changed significantly.
