标题: prep74我有一个强烈的疑问，拜托大家帮我看看吧谢谢

74. (28503-!-item-!-188;#058&003635)

Paleontologist Stephen Jay Gould hasargued that many biological traits are not the products of

natural selection, favored due to theirenhancement of reproduction or survival, but that they are

simply random by-products of otherevolutionary developments.

(A) due to their enhancement ofreproduction or survival, but that they are

(B) due to the reproduction or survivalthey enhance, but they are

(D) because they enhance reproduction orsurvival, but are

(E) because of enhancing reproduction orsurvival, but are

答案是D 可是难道D项那个they没有指代问题吗？？我觉得相比之下E更好啊

没有啊~~they指代biological traits~~

个人感觉当because和because of 同时出现时，优选because

另外because of +动名词，不太好吧~~

那为什么不能指products？

many biological traits are not...., but are.....这样才平行啊~~

“the products of natural selection” 和后面那个“simply random by-products ”平行
