[讨论]请教大全６３８，关于ｓｕｃｈ　ｔｈａｔ，　ｓｕｃｈ　ａｓ　ｔｏ的优先问题！

such sth as to，我没找到及见到此种结构，如有，请告之。

即使有（sht1 do ）such sth2 as to用法，在这里也不行，因为to不定式的逻辑主语则有歧义，

至于D中they则优先指代前面主句主语，从语法和从逻辑上指代都对

check this question cited from OG.  you might understand.

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（D）

(E) in order that he would marry

The sentence calls for an adverbial clause of purpose to explain why Henry sought the annulment. D, the best choice, does this clearly and correctly. It is introduced by an appropriate conjunction, so that, and contains a logically appropriate verb form, could marry. Awkward and imprecise, A does not specify who is to marry Anne. B substitutes an illogical coordinate predicate for the needed purpose clause; because the annulment had not yet been granted, Henry could not remarry. C lacks an appropriate conjunction, and the infinitive clause to be married to... makes this choice awkward and unidiomatic. Although E uses an appropriate conjunction, in order that, the verb form would marry is unidiomatic and illogical (might marry would be better).

1.         but some of these drugs caused such severe stomach disorders that they were banned by the Food and Drug Administration.D

此处用that they were原因，我觉得是前后主语不一致导致，前面主语some of drugs,而后面they则是drugs.

看了大家以上的讨论， 我想下面一个题也很有代表性，请NN们指教：

14.   Researchers have questioned the use of costly and experimental diagnostic tests to identify food allergies, such as milk, that supposedly disrupt normal behavior.

(A) to identify food allergies, such as

(B) to identify food allergies, like

(C) to identify food allergies, such as to

(D) for identifying food allergies, like that of（C）

(E) for identifying food allergies, such as for

这里的such as to 如何解？ 查了字典， 意思是“达到这样的程度以致” ，比如His speech is such as to incur enmity，但在该题中， 后面接一个名词milk 是怎么回事？ A为什么不对 ？
