Question

【题目】Living in the central Australian desert has its problems, _____ obtaining water is not the least.

A. of which B. for what

C. as D. whose

Answer 1

【答案】A

【解析】本题中含有一个定语从句，先行词是problems，与从句构成obtaining water is not the least (one) of the problems，因此引导词用of which。句意：生活在澳大利亚沙漠中心有很多问题，找水并不是最糟糕的那一个。
