By manipulating resources, being either algae or bacteria, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structure of communities or not.

OFFICIAL EXPLANATION
By manipulating resources, being either algae or bacteria, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structure of communities or not.
A. algae or bacteria, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structure of communities or not
In the GMAT, the addition of the phrase or not at any point after the word whether is considered redundant.
B. bacteria or algae, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structure of communities
This answer choice corrects the Redundancy created by using the phrase or not after the word whether.
C. algae or bacterial, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structure of communities
While this answer choice fixes the original Redundancy error by eliminating the words or not after the term whether, it is still grammatically incorrect. The same part of speech that follows either must also follow or. Either is followed by the noun algae. Or, however, is followed by the adjective bacterial.
What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign: (n)either... (n)or...
D. algae or bacteria, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines if history affects the structure of communities
In the GMAT, the word if is used in Conditionals only; if one thing, ...then something else. Since in this question there is no condition, if should be replaced by whether.
Whether is used 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)
E. algae or bacteria, which are available to ciliates in a closed aquatic microcosm, scientists were able to prove that resource specialization determines whether history affects the structured communities
While this answer choice fixes the original Redundancy error by eliminating the words or not after the term whether, it changes the meaning of the original sentence. The phrase structured communities does not mean the same thing as the structure of communities.
