Sentence Correction: Redundancy - Double Conjunctions or Phrases

Because of the increase in exposure to innovative forms of education, consequently many parents are unsure whether the traditional schooling method is best for their children.

This answer choice is stylistically incorrect. Including both a reason conjunction (Because) and a conclusion conjunction (consequently) to express the relation between two parts of a sentence is redundant. The use of a Double conjunction is one of the specific redundancies that should always be corrected.

What helps us identify this Redundancy is the following Stop Sign:

Because/Since/Due to/As later followed by so/therefore/thus/consequently

The original sentence uses both a reason conjunction (Because) and a conclusion conjunction (consequently) to express the relation between two parts of a sentence. Although this answer choice corrects this redundancy, in the GMAT, If should be 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)

The original sentence uses both a reason conjunction (Because) and a conclusion conjunction (consequently) to express the relation between two parts of a sentence. Although this answer choice corrects this Redundancy, in the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant.

Great!

Including both a reason conjunction (Because) and a conclusion conjunction (consequently) to express the relation between two parts of a sentence is redundant. This answer choice removes the conclusion conjunction (consequently) and uses a reason conjunction (therefore) to correct the Redundancy.
