标题: feifei 49
Joseph: My encyclopedia says that the mathematician Pierre de Fermat died in 1665 without leaving behind any written proof for a theorem that he claimed nonetheless to have proved. Probably this alleged theorem simply cannot be proved, since---as the article points out---no one else has been able to prove it. Therefore it is likely that Fermat was either lying or else mistaken when he made his claim.
Laura: Your encyclopedia is out of date. Recently someone has in fact proved Fermat’s theorem. And since the theorem is provable, your claim---that Fermat was lying or mistaken---clearly is wrong.

49. Joseph’s statement that “this alleged theorem simply cannot be proved” plays which one of the following roles in his argument?
(A) an assumption for which no support is offered
(B) a subsidiary conclusion on which his argument’s main conclusion is based
(C) a potential objection that his argument anticipates and attempts to answer before it is raised A
(D) the principle claim that his argument is structured to refute
(E) background information that neither supports nor undermines his argument’s conclusion

Key: B.
Joseph doesn't provide and evidence for his statement"*** cannot be proved" how can it be called subsidiary conclusion.
I think the answer is A, why A is not right.

A 错在for which no support is offered。 J还是给了support 的。即：since---as the article points out---no one else has been able to prove it.

我选的也是A，我首先认为“this alleged theorem simply cannot be proved”是个assump，而不是conclusion，所以，我就选A了。

楼上的解析我也不明白，能否说的更细一些？

另外，F－50题的C项“It mistakes something that is necessary for its conclusion to follow for something that ensures that the conclusion follows. ”如何翻译？敬请指点！

A不是假设，把题干意思翻译出来你就看清楚了：F去世后剩下许多他声称已经证明的理论。但可能这些理论是不能证明的，因为没有任何一个人能够证明的（这里是作者的一个观点，，并提出一个原因since……来证明，所以不是假设）。因此，F可能是说谎或犯了错误（这个是通过中间的观点进一步推出的结论）。

不知这样翻译出来会不会清晰一点。

原文第一句是论据1：Fermat没有留下证明

第二句，since后面是论据2：其他人也不能证明

since前面是mid－conclusion：也许这个理论根本就不能证明

第三句是Conclusion：那么Fermat说他已经证明了，就是在撒谎或者搞错了
