23. Oberlin
                College in Ohio was a renegade institution at its 1833 founding for deciding to accept both men and women as students.
(A) at its 1833 founding for deciding to accept
(B) for the decision at its 1833 founding to accept
(C) when it was founded in 1833 for its decision to accept
(D) in deciding at its founding in 1833 to accept
(E) by deciding at its founding in 1833 on the acceptance of

答案是D，为什么呢？不清楚考点在哪里。

A中its 1833 founding 不对,应该要把1833放在后面,改为in 1833,for doing 不对,表示目的

B同上

Cfor its decision不对,表目的

Eby 的使用逻辑有错误,另外on the accepance of 没有动词accept简洁
