标题: prep1-74

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

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

(D) because they enhance reproduction or survival, but are

(E) because of enhancing reproduction or survival, but are

请问favored是什么词性？形容词吗？那它表many biological traits are not the products of natural selection的伴随吗？还是修饰selection？还是表Paleontologist Stephen Jay Gould has argued that 。。。的伴随？盼望大牛的指导！

非牛。

好像是biological traits的动词，意思应该是“得益于”。

答案是A么？
