58、Both the complexity of the phenomenon known as extinction and the vastness of the biosphere, having prompted many scientists to call for a large increase in the number of biologists working both in the field and in laboratories to clarify the relationships among the planet's many endangered life-forms.
　　(A) and the vastness of the biosphere, having prompted many scientists to call for a large increase in the number of biologists working both
　　(B) and the vastness of the biosphere has prompted many scientists calling for a large increase in the number of biologists both working
　　(C) and the vastness of the biosphere have prompted many scientists to call for a large increase in the number of biologists working both
　　(D) as well as the vastness of the biosphere have prompted many scientists to call for a large increase in the number of biologists who both work
　　(E) as well as the vastness of the biosphere has prompted many scientists to call for a large increase in the number of biologists who work both
　　原文意思：
　　两个东西促进科学家呼吁那种在两个领域都能工作的生物学家尽可能多一些。
　　题目分析：
　　A 没有谓语， 干掉。 B 读到 has prompted 就不对劲了， prompt 这个动词的发起者是有 both and连接的两个东西，不能用 has，干掉。C 用 have，前后一致，保留。D 用 both work，应该是 work both in 一个地方 and in 另一个地方，如果用 both work 就不是两个地方形成并列了，而是 work in 一个地方和 in 另一个地方对应了，多了个 work，干掉。E 也用 has，主谓不一致。
