The average rainfall in Ningxia is small, makes the climate here is drier
with other cities in China.
A. that; compared
B. which; comparing
C. which; compared
D. that; comparing

A. that; comparedB. which; comparing(答案→)C. which; comparedD. that; comparing解析：考察非限定性定语从句关系代词用法，在非限制性定语从句中，当从句内容修饰前面整句话内容时，不定代词只能使用which。在这种从句中，which可以作主语。过去分词往往表示发生过的被动的动作，现在分词则表示正在发生的，伴随性的动作，与其他城市相比，是被动语态，故选C。宁夏的平均降水量很小，使得这里的气候同中国其它城市相比更加干旱。

这个答案应该是对的
