OG语法141

Walkens

OG141：
Unlike transplants between identical twins, whose genetic endowment is the same, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.
(A)Unlike transplants between identical twins, whose genetic endowment is the same
(C)Unless the transplant involves identical twins who have the same genetic endowment
(D)Aside from a transplant between identical twins with the same genetic endowment

这个题目中我选了D但答案是C，我不知是为什么，请各位高人帮我解答一下

excellences

aside from 有两个意思。

aside from somebody/something especially American English

a) except for:

Aside from Durang's performance, the actors are ordinary.

b) in addition to:

In the poetry competition, aside from Hass, are four other entrants

另外，我记得OG关于C的解释是因为 with the same genetic endowment是限定identical twins,那意思就是有些identicaltwins 是genetic 相同的，有些是不相同的。所以用with不对。
