115. School superintendent: It is a sad fact that, until now, entry into the academically best high school in our district has been restricted to the children of people who were wealthy enough to pay the high tuition. Parents who were previously denied the option of sending their children to this school now have the option, since I am replacing the tuition requirement with a requirement that allows only those who live in the neighborhood of the school to attend.

The superintendent’s claim about the effect of replacing the tuition requirement relies on the assumption that

A.        the residents of the school’s neighborhood tent to be wealthy

B.        people other than those wealthy enough to have paid the old tuition are able to live in the neighborhood of the school

C.        people less wealthy than those who were able to pay the old tuition are in the majority in the district

D.       there are no high schools in the district other than the one referred to by the superintendent

E.        there are many people not wealthy enough to have paid the old tuition who wish to have their children attend the school

答案：B

思路： 本题中的替代办法必须顾及两点，一交不起老学费的可以来读书，而且交不起学费的应能够 live in the neighborhood of the school，如果穷人不能住在这个学校附近，这个替代是无意义的。

A.        反对文中办法。

B.         文中没有提到符合题意。

C.         太偏，文中只讨论the neighborhood of the school，are in the majority in the district并不意味着live in the neighborhood of the school。

D.        文中没有提到。

E.         易混淆，文中已经包含这个意思，不是题目要问的问题。

答案是B没有疑问

但是感觉C也对啊 哪里是trick了

谢谢

C. People less wealthy than those who were able to pay the old tuition are in the majority in the district.

The "are in the majority" is the problem.

Try deny test on C, we get "People less wealthy than those who were able to pay the old tuition are not in the majority in the district."  But this could still mean that there are many less wealthy people in the district, although they are not in the majority.  If so, the superintendent's claim "Parents who were previously denied the option ... now have the option" could still be true.  Therefore, C is not a necessary assumption of the claim.

robert, thank you very much.

I got it now. Hope that i can avoid such problems. Thank you.
