问题描述：
That was the reason__ Mr Smith refused to speak for at yesterday's meeting
A.why
B.what
C.which
why chose
答
应该选A，答案是否有错，如果选C的话此句话应该是 That was the reason for which Mr Smith refused to speak for at yesterday's meeting.
do sth for some reason
the reason why是固定搭配，答案估计有错
答
因为which修饰the reason.如果选A，那么就要去掉the reason.变成That was why Mr Smith refused to speak for at yesterday's meeting .
答
从reason 后面开始是一个从句 修饰reason 从句中缺少宾语 which 就指代了reason
