GWD 第１套　q13

Q21:
(That twenty-one ceramic dog figurines were discovered during the excavating of a 1,000-year-old Hohokam village in Tempe, Arizona, has nearly doubled the number of these artifacts known to exist.

A.    That twenty-one ceramic dog figurines were discovered during the excavating
B.    Twenty-one ceramic dog figurines discovered at the excavation
C.    Discovering twenty-one ceramic dog figurines at the excavating
D.    Ceramic dog figurines, twenty-one of which were discovered during excavating
E    The discovery of twenty-one ceramic dog figurines during the excavation

黄色部分是需要修改的。答案是ｃ．我选的是ｅ。我觉得ｃ的ｄｉｓｃｏｖｅｒｉｎｇ有进行时的意思，从题目上看应该已经发掘完了，为什么ｅ不可以呢？是不是ｄｕｒｉｎｇ用的不对？

请教一下大家。
