Sentence Correction: Comparatives - As vs. Like

The decision whether or not to adopt a child is a complicated one and prospective parents should seek professional advice, as most people do

In the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant and, therefore, a stylistic error. Look for a more concise answer choice.

While this answer choice fixes the original Redundancy error by eliminating the words or not after the term whether, it is grammatically incorrect. A comparative section beginning with as should always include a conjugated verb. The comparative section in this answer choice (as most people), however, does not include a verb.

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

Like, unlike, than, as

This answer choice repeats the original Stylistic error. In the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant. Look for a more concise answer choice.

While this answer choice fixes the original Redundancy error by eliminating the words or not after the term whether, 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)

Great!
