The new political reform bill proposed by Chinese expatriates will almost certainly fail to pass during the next National People's Congress. All the leaders of the ruling party have stated openly that they would oppose it, out of concern for the potential damage to the nation's stability and prosperity.

Which one of the following statements, if true, provides the most support for the prediction that the new political reform bill will fail to pass during the next National People’s Congress?

A. If all the leaders of the ruling party endorse the new political reform bill before hand, it will pass into law.
B. Most bills at the National People’s Congress, which have not been passed into law, were not supported by even one leader of the ruling party.
C. Most bills at the National People’s Congress, which have not been supported by even one leader of the ruling party, have not been passed into law.
D. Most bills at the National People’s Congress, which have been passed into law, were not unanimously supported by the leaders of the ruling parties.
E. Most bills at the National People’s Congress, which have been passed into law, were supported by at least one leader of the ruling party.

选C，这题让我把常识也混进去了……想把E也一起选……嗯，这算是常识吧……

选E，在C和E中抉择了一下，答案是什么？

C：大部分不被甚至一个执政党党员支持的提议不会通过立法表决
E：大部分通过立法表决的提议得到了至少一个执政党党员的支持

选最支持提议最终失败的选项，感觉E更直接，说不来，C言外之意还是有可能通过立法表决的

twobirds

应该是C选项吧,
“全部反对”推到“法案不通过”；
逆反命题：“法案通过”推到“全部赞同”，也就是“全部赞同”是“法案通过”的必要条件，
C选项表达的就是，“哪怕一个人投反对票，法案就不会通过”，就是这个意思

我觉得是选E。。
就是不很肯定all的否定是都没有还是说至少有一个。。。
感觉C有个gap就是全部都不支持不一定就是指全部都反对，因为或许有既不支持也不反对的中立的可能。。。
（也或许是我钻牛角尖了。。。）
恩
就这样吧E。。
考试时候这样我就over了。。。

Kevin and Twobirds were right

We know from the stimulus, that the new bill has not been supported by even one leader of the ruling party. Then coupled with answer (C), which says "most bills at the National People’s Congress, which have not been supported by even one leader of the ruling party, have not been passed into law", it is likely that the new bill will not pass into law.

Both C and E look attractive.  The key difference is that the former talks about those bills that failed to pass while the latter touches on those that DID pass.  But the stimulus is about a bill that is likely to fail.  So we do not care about those bills that got passed.  Hence, the answer is C. We need to focus on the answer choices that help us to deduce that the bill will not pass.

In other words, we are looking for attributes of bills which failed to pass, not attributes of bills which passed.

C跟题干构成一个演绎推理的逻辑结构，E顶多是一个归纳推理。显然C比较强大。

能不能指出我的问题呢？
原文逻辑：全部反对---->法案不通过
那么逆否命题：不全部反对<------法案通过
那么也就是说，如果一个法案是通过的，那么就不全部反对，即至少有一个支持的。这不就是E吗？
我错在哪里？

But we do not care about those 法案是通过的. The passage wants to deduce what 法案不通过
