Sentence Correction: Comparatives - Like/Unlike

Food production companies know that children, like many adults, enjoy high amounts of sugar and are uninterested as to whether a certain food product is healthy.

In the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant.

In the GMAT, If is used in Conditionals only. If you see if in a sentence and there's no condition, you should replace if with whether.

Think of whether as a choice between two possibilities dealing with the same subject or as a yes/no question.

Example: I do not know whether this will work. (yes or no)

He was not sure whether he wanted banana or chocolate cake. (a choice between 2 possibilities)

This answer choice is grammatically incorrect. The like section should not include a conjugated verb. In this answer choice, however, the like section includes a conjugated verb (like many adults do).

What helps us identify this question as a Comparative question as well as identify the mistake is the following Stop Sign:

Like, unlike, than, as

Very Good.

Not only did you not fall into the Comparatives confusion (and properly allowed for like to compare nouns), but also, you did not fall into the if vs whether trap and properly maintained the correct Subject Verb Agreement between product and healthy.
