The mere fact _______ most people believe nuclear war would be madness does not mean that it will not occur.

问题描述:

The mere fact _______ most people believe nuclear war would be madness does not mean that it will not occur.
a、what
b、 which
c、 that
d、 why
为什么选C,请翻译整句

应该是c,
这是一个定语从句
仅有的事实——大多数人认为核战争疯狂,不代表它将来不发生.
that 和which可以代表物(that 代表人和物都行),why代表原因,而定语从句中不用what.
所以a d可排除.
如果前边有修饰词时(very,any,all,some,no,little,few,much,mere),只能用that引导.
