标题: prep争议题，求解答
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.
- Adue to their enhancement of reproduction or survival, but that they are
- Bdue to the reproduction or survival they enhance, but they are
- Cbecause they enhance reproduction or survival, but
- Dbecause they enhance reproduction or survival, but are
- Ebecause of enhancing reproduction or survival, but are
某考试网站给出的答案是D。选项c错在歧义，选项E错在because of+现在分词 无效。楼主选的是C。看了好久都没有看出问题，然后对于favored后面的句子无法理解，不知道favored...是修饰哪里的。求解救，谢谢！

非牛，我觉得是这样的
but作为连词，左边是一个句子，如果右边是一个名词by-product，也就是C选项，那么by-product有可能跟but前面的其他名词表示并列关系。如果加上are，那么就加强了表示but后面和前面主句中的平行关系
favored那个分句修饰the products of natural selection
不能确定完全正确，如果错误还望指正。

我也会选C,不知道为什么答案是D

虽然 not...but...是封闭式平行，要求绝对平行。
但是语义是更重要的。
从语义角度理解，生物的特质不是自然选择的产物，而是进化发展的副产品。
不是。。。而是。。。 有是的意思，所以把are加上去
not are....but are....但是nor are 这种表达不符合英语表达的习惯，改成了are not. 但是后面还是要把are补出来。

不同意选D 认为选C没有问题
作者: 宋痂岛__ 时间: 2018-7-2 15:47
but前的comma已经消除了歧义，but后的名词不可能与comma前的名词平行.

我觉得D， 首先are ..., but are.. 和 are not..., but... 平行都是对的。
但是因为not...but...封闭结构如果成立后面应该加个冠词the 和前面保持平行。
即，the products 和 the by-products 平行。
而原文中没有the 就考虑第一种平行。

here is the explanation from RON:
basically, here's the difference:
• "not X but Y":
this construction implies that X is what's "normal" or "expected", and that Y is what's actually true.
e.g.,
I was surprised to learn that Ella was not Clint's biological daughter but in fact his adopted daughter, since her facial features so closely resemble his.
(here, since the girl looks so much like her dad, we EXPECT to find out that she's his biological daughter.)
• "X but Y":
this just implies a contrast, but NOT any expectation.
(in THIS PARTICULAR sentence—as already explained in this thread—the "X" part includes the word "not".)
e.g.,
I am not a mechanic, but can perform basic maintenance on non-hybrid cars.
__
this sentence DOES describe a contrast—these things aren't products of natural selection, BUT they ARE products of essentially random selection processes.
on the other hand, it DOES NOT describe any sort of situation with an "expected" or "predictable" result.
thus it should not use the first construction; it should use the second one.
to make this sentence into "X, but Y", we need to include the are on the right-hand side.

I received a PM asking me to comment.
In C, the meaning is not crystal clear:
...products of natural selection, favored...but simply random...
The construction above could imply -- incorrectly -- that both favored and random modify products.
In D, the parallel structure are not...but are makes it crystal clear that random refers not to products but to traits:
...traits that are not the products of natural selection...but are simply random by-products of other evolutionary developments...
It must be clear what a modifier is modifying. Since D makes the meaning crystal clear, eliminate C and choose D.
