This question is basically trying to measure your capacity to read for meaning in parallel structures. However, I suspect that the correct answer choice (E) does poorly its intent, because GMAT is very strict in terms of "which" usage. "Which" should only refer to previous term.

Read for meaning: The sentence wants to compare new varieties of antibiotics with earlier varieties. Pay attention to where the term "earlier high-strengh varieties" is located in the sentence. Any choice that refers only to one aspect of "earlier high-strengh varieties", you can eliminate it. Go ahead and cross these answers out:

New, strong varieties of antibiotics show the potential to kill a harmful bacterium without the unintended effects of killing benign bacteria and development of resistant strains of bacteria by earlier high-strength varieties.

a. unintended effects of killing benign bacteria and the development of resistant strains of bacteria by earlier high-strength varieties - linked only to the 2nd aspect
b. unintended effects by earlier high-strength varieties of development of resistant strains and killing benign bacteria - linked only to the 1st aspect
c. unintended effects for the development of resistant strains of bacteria and killing benign bacteria of earlier high-strength varieties - linked only to the 2nd aspect
d. development of resistant strains of bacteria and killing of benign bacteria that were required by earlier high-strength varieties - linked only to the 2nd aspect, no comma, no distribution
e. killing of benign bacteria and development of resistant strains of bacteria, which were unintended effects of earlier high-strength varieties - close enough to refer to both terms, but notice that "which" actually refers to a term used in the beginning of the phrase "new, strong varieties of antibiotics"

1. unintended effects of killing benign bacteria and the development of resistant strains of bacteria by earlier high-strength varieties
2. unintended effects by earlier high-strength varieties of development of resistant strains and killing benign bacteria
3. unintended effects for the development of resistant strains of bacteria and killing benign bacteria of earlier high-strength varieties
4. development of resistant strains of bacteria and killing of benign bacteria that were required by earlier high-strength varieties
5. killing of benign bacteria and development of resistant strains of bacteria, which were unintended effects of earlier high-strength varieties


It is very important to make sure we understand the meaning of the original sentence. The meaning here is as follows:
New, strong varieties of antibiotics show the potential to kill a harmful bacterium without the unwanted effects that the older strong antibiotics had: the killing of benign bacteria and development of resistant strains of bacteria

Answer B includes the incorrect expression "effect BY," the correct idiom is "effect OF something." It also changes the meaning of the original sentence quite significantly. The expression "by earlier high strength varieties of development." So the sentence does not say that the development is the effect of older antibiotics. It states that it is the "varieties of development" that had some effect. In result the sentence is illogical.

Unfortunately I picked option A here. I didn't quite like the which in answer choice E, but not too convinced either with the second part of the sentence for answer choice A

Please advice
Thanks!
Cheers

1. New, strong varieties of antibiotics show the potential to kill a harmful bacterium without the unintended effects of killing benign bacteria and development of resistant strains of bacteria by earlier high-strength varieties.

5. New, strong varieties of antibiotics show the potential to kill a harmful bacterium without the killing of benign bacteria and development of resistant strains of bacteria, which were unintended effects of earlier high-strength varieties

There is a huge meaning shift in 1 AND 5.

1. without the unintended effects of killing benign bacteria
5. without the killing of benign bacteria

1 talks about effects of killing whereas 5 talks about killing of benign bacteria.

I would say its a poor quality question.
