问题 Living in the desert involves a lot of problems, _______ water shortage is the worst.

选项 A、not to mention
B、of which
C、let alone
D、for what

答案B

解析 考查带介词的定语从句。of which引导非限制性定语从句,which指代problems。若把先行词和定语从句还原为:Living in the desert involves a lot of problems,water shortage is the worst(of it)。更容易确定答案为B。
