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

(E) for identifying food allergies, such as for

I chose option A, but the OA is C. But I thought that the phrase "such as to" is considered wrong always. In fact, here is a list of 3 different constructions that I came to understand as always wrong, and, please guys, correct me if I am wrong:

1) So much so that....
2) So as to.....
3) Such as to.....

If it is true that this list of 3 different constructions are always wrong, then what am I missing here and why do we have an exception in this problem?
thanks

The idiom here is "alergy to".
They just put some stuff between "alergy" and "to" and because there's an example given there's also "such as" thrown in there.

Something to milk is an allergy....

Thanks guys. I think "Alergies to" is the tested issue here. I think what we should learn from this problem is that idiomatic expressions can be split apart. As for the infinitives, however, they NEVER should be split. Once you detect an idiomatic expression, always be open to find its other half somewhere in the sentence. But one last question guys, are the 3 constructions that i've listed accurate? Are we really suppose to avoid answer choices that contain such wordings?
thanks

My 2 cents..

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-> word following such as points back to allergies thus eliminate it(milk is not an allergy)

(B) to identify food allergies, like -> again milk is not allergy,

(C) to identify food allergies, such as to-> means allergies because of milk, sounds good

(D) for identifying food allergies, like that of-> sounds awkward, eliminate it

(E) for identifying food allergies, such as "for"-> awkward usage.eliminate it

1) So much so that....
2) So as to.....
3) Such as to.....

If it is true that this list of 3 different constructions are always wrong,-> no I don't think so, if you have easier and correct options, we should go for them as these are wordy then what am I missing here and why do we have an exception in this problem?
thanks
