Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored due to their enhancement of reproduction or survival, but that they are simply random by-products of other evolutionary developments.
(A) due to their enhancement of reproduction or survival, but that they are
(B) due to the reproduction or survival they enhance, but they are
(C) because they enhance reproduction or survival, but
(D) because they enhance reproduction or survival, but are
(E) because of enhancing reproduction or survival, but are
A選項their(the products of natural selection)和they(biological traits) 同一代名詞指代不同 所以不選
B選項兩個they所指的東西不一樣。第一個they是the products of natural selection。第二個they是biological traits。 同一代名詞指代不同 所以不選
這樣的思路有誤嗎??
還有想請問due to 的用法??有人可以幫我解釋嗎?? 什麼叫做 due to + 動作名詞不夠有效??
