I tried to get out of the business _______ I found impossible to carry on.
A
why
B
which
C
what
D
where
答案解析
正确答案：B
解析：
参考解析:关系代词辨析。选择关系代词时要看先行词在后面的从句中充当什么成分。本题的先行词为business，是从句中充当动词词组carry on的宾语，因此这里需要一个充当宾语的关系代词，只有这样定语从句的关系代词和先行词才能保持一致，因此选B。A项why和D项where是关系副词，引导定语从句时，一般在从句中作状语，C项what充当关系代词时，不能引导定语从句。句意:我试图从那件事务中抽身，我发现我不可能一直干下去了。
