一道有趣的题

偶然发现一道题的选项混淆的很有意思，供大家共同探讨。请给答案的同时给理由，理由才是最重要的，因思路是最重要的。

Sally:I cannot study at a university where there is an alcohol problem. So unless something is done about the alcohol problem at this university, I’ll have to transfer to a university where there are no fraternities.

Which one of the following is an assumption on which the Sally’s argument depends?

(B) Nothing will be done about the alcohol problem at Sally's university

(E)There could be universities that have no alcohol problems.

I choose E.

Sally认为有无酗酒问题的大学存在，所以才会想转学。

B is wrong, 因为Sally只是说unless。如果把unless一句去掉，那么B也正确。

I choose E.

the reason is simple;

There is no actual transfering of Sally. She is only explaining a condition.

IF we negate B:

Something will be done about the alcohol problem at Sally's university.==> What we reach is not the opposite of the argument, but the negation of the premise.

In fact, for the real assumption, if we negate it, the total argument will not stand.

Discussion welcome

选B的理由是：1。原文逻辑为：这个大学有ALCHOL问题，我不可能在有ALHHOL问题的大学读书。所以，我不得不转学。2。如果这个大学解决了这个问题，我就不用转学了。SO后面的句子也是这样假设。B排除这个可能性。故为假设。

选E的理由是：1。原文逻辑为：我不可能在这样有ALCHOL问题的大学读书，所以我不得不转学，除非这个大学的这个问题有改观。2。但如果其他大学也有这个问题，则一样转不了学。E排除这个可能，故也可为答案。

那末问题出在哪里呢。

同意ICEBOY的意见。

这里关键的问题是，她只是说说，WILL，还没转呢？如果她说MUST，那就不同了。

另外请问大家，她为什么说THERE ARE NO FRATERNITIEs..WHAT does fraternities mean here and what 's their relationship with alcohol problem?

I think you made a mistake here.

Sally:I cannot study at a university where there is an alcohol problem. So unless something is done about the alcohol problem at this university, I’ll have to transfer to a university where there are no fraternities.

这里说的是a university

说的是要不要转到没有ALCOHOL的地方去, 并不管这个有地方是哪个地方. SALLY必然是默认有这种地方才能得到结论.

至于SALLY的UNIVERISTY到底会不会有something to be done.完全是无关于论证的.

Which one of the following is an assumption on which the Sally’s argument depends?

(B) Nothing will be done about the alcohol problem at Sally's university.

(E)There could be universities that have no alcohol problems.

agree with iceboy；

assumption题形答案是原文结论的必要条件。原文的结论I’ll have to transfer to a university where there are no fraternities。将B取非后，something will be done，并不能说明能解决alcohol 的问题，有可能会更严重，有可能没有改变，所以B不是原文的必要条件。而将E取非后，所有的学校都存在alcohol  problem，原文的结论就不能成立了。E是原文的assumption。

assumption的题形可以参见这个帖子：

FYI.

Sally: I cannot study at a university where there is an alcohol problem. So unless something is done about the alcohol problem at this university, I'll have to transfer to a university where there are no fraternities.
Yolanda: I don't agree that fraternities are responsible for the alcohol problem at this university. Alcohol problems exist at all universities, including those where there are no fraternities. We all should become more aware of alcohol abuse. It's not simply a fraternity problem; it's a cultural problem.

Which one of the following is an assumption on which Sally's argument depends?
(A) Most universities have fraternities.
(B) Nothing will be done about the alcohol problem at Sally's university.
(C) Alcohol problems are becoming more widespread at universities.
(D) Some fraternity members who drink alcohol beverages are too young to do so legally.
(E) There could be universities that have no alcohol problems.
