We went though a period___communications were difficult in the rural areas.
A whichB whoseC in whichD with which
为什么选C
答
考查定语从句，先行词a period表示的时间词，___communications were difficult in the rural areas.这是一个完整的 句子，所以横线部分少的是时间状语，这填when=in which ,which指的是a period
答
in which在这里等于when，in the period即which代的是前面的period
我们经历过那段时间，那时，农村/郊区的通讯很困难。
答
period做先行词.
而后面的定语communications were difficult in the rural areas in that period,所以必须是C
