Dear
Rock750,
This is a great question, and I am happy to help.
The first split I'll point out is the placement of the word "
not." This is a subtle issue of
Logical Predication. See this blog for a more detailed discussion:
https://magoosh.com/gmat/2013/logical-pr ... orrection/The contrast is in the two putative inventors, so the "
not ... but" structure should included only these two: "
invented not by Bunsen but by Faraday." If the word "
not" comes before the verb "
invented", it creates the impression that we are contrasting the action of "inventing" with some other action --- that is not the case here. The answers with the word "
not" in front of the word "
invented", choices
(B) &
(D), are incorrect.
Choice
(A) is sleek, elegant, and perfectly correct.
Choice
(C) is a little wordier, and it illogically places the preposition "in 1885" right after the words "fellow scientist", as if Faraday were Bunsen's fellow scientist only for that one year. That is illogical and incorrect.
Choice
(E) is the worst of the worst: the present participle "
naming" is active, so it must modify the person doing the naming, not the object named. For more information, see:
https://magoosh.com/gmat/2014/gmat-gramm ... ive-verbs/Choice
(E) is entirely incorrect.
The only possible answer is choice
(A).
Does this make sense?
