※ 引述《fangmole (Dean)》之銘言：
74.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.
(C) because they enhance reproduction or survival, but
(D) because they enhance reproduction or survival, but are
想詢問實戰上C、D的解題方法/觀念
看了Ron及語法筆記的解釋仍然不太明白為何選C會造成ambiguous
感謝各位版上神人釋疑！！

平行方式如下: biological traits are not the products,
(because they enhance reproduction or survival,) --> 插入
but are simply random by-products
如果像 (C) 沒有加 are 那有可能變成
平行方式如下: (biological traits are not the products),
because they enhance reproduction or survival,
but simply random by-products
所以必須要有 are 才能確認平行定位位置
