问题 The rescue team must have searched for the missing visitors in the earthquake two days ago,______?

选项 A、mustn’t they
B、haven’t they
C、didn’t they
D、hadn’t they

答案 C

解析如果陈述部分含有表示推测的情态动词must，其反问部分应根据具体情况而定。对过去发生的动作或存在的情况推测时，若表示肯定，则用haven’t或hasn’t；但如果句中有表示过去的时间状语，如yesterday，two days ago等时，则用didn’t。本题表示的是对过去的肯定推测，并有一个表示过去的时间状语two days ago，因此应当用didn’t they，故答案为C)。
