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.

	That twenty-one ceramic dog figurines were discovered during the excavating
	Twenty-one ceramic dog figurines discovered at the excavation
	Discovering twenty-one ceramic dog figurines at the excavating
	Ceramic dog figurines, twenty-one of which were discovered during excavating
	The discovery of twenty-one ceramic dog figurines during the excavation E是答案，可是翻译出来是“发现doubled了艺术品的数量”。这个发现能够doubled数量吗？而我认为应该是一个什么东西doubled了数量，所以比了一下，选了B,请NN指点

B当中Twenty-one ceramic dog figurines（复数）作为主语后面不能跟has
E当中由于这个发现导致了数量上的double 我觉得符合逻辑
