请nn现身——og11-36（即og171），关于so as to的经典问题，对og11中的解释有疑惑

171. In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled so as to marry Anne
Boleyn.
(A) so as to marry
(B) and so could be married to
(C) to be married to
(D) so that he could marry
(E) in order that he would

This sentence uses the construction x happened so that y could happen; so introduces a clause of purpose
                or result, explaining the reason for the action in the main clause. Henry ... sought to have his marriage ... annulled so that he could may Anne Boleyn. The relationship between the two clauses is clear.

A So as to marry is not idiomatically correct; it does not identify who will marr

B         This alternative is ungrammatical and illogical: Henry could not marry simply on the basis of seeking an annulment

C         The infinitive must be preceded by a conjunction
                    (in order); to marry is preferable to the wordier to he married to

D         Correct. This sentence^'s construction clearly shows the reason that Henry sought an annulment.

E         In order that is followed by may or might, the conditional would marry is incorrect .

C的解释说，应该改成in order to marry就对了。

可是longman字典上

so as to do something = in order to do something:
I drove at a steady 50 mph so as to save fuel.
We went along silently on tiptoe so as not to disturb anyone.

这就是说A也是对的了？

以前无数个讨论贴，都是针对og10的，现在og11的新解释多了几句话，又看不懂了。。

。

谢谢回复。

请读全C项的解释：The infinitive must be preceded by a conjunction
            (in order); to marry is preferable to the wordier to he married to

他的意思是to be married to如果用“in order to marry”，就没有问题了。

11应该这个地方有些小的错误，别再去想了

so as to的用法一直是错的，至少在GMAT中是错的

只有so...as to 有时会是正确选项，具体用法不细说了
