GWD 14中的两道题求教

搜了一下没搜到，只好腆着脸发新帖

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.

1. That twenty-one ceramic dog figurines were discovered during the excavating
2. Twenty-one ceramic dog figurines discovered at the excavation
3. Discovering twenty-one ceramic dog figurines at the excavating
4. Ceramic dog figurines, twenty-one of which were discovered during excavating

E    The discovery of twenty-one ceramic dog figurines during the excavation

感觉 discovery 做double 的主语不合适，我选的是A， That结构做主语。

上面这题我觉得是不是excavation和excavating的区别呢？毕竟动名词表示一个持续的动作或者状态。

下面这题如果是D的话可能产生歧义并且改变原文意思。因为D没有提到谁吃了这些食物，或许是法国和美国的动物，或许是法国和美国的人和动物的总消耗。
