(B) has been not only an indication but also a stimulus to

Concepts tested here: Parallelism + Idioms• “both A and B" or "A as well as B" are the correct usages; A and B must be parallel and comparable.
• “not only A but also B” is the correct, idiomatic usage; A must be parallel to B.
A: This answer choice fails to maintain parallelism between A ("an indication") and B ("a stimulus to") in the idiomatic construction "both A and B"; please remember, "both A and B" is a correct, idiomatic usage; A and B must be parallel and comparable.
B: This answer choice fails to maintain parallelism between A ("an indication") and B ("a stimulus to") in the idiomatic construction "not only A but also B"; please remember, "not only A but also B" is a correct, idiomatic usage; A and B must be parallel and comparable.
C: This answer choice fails to maintain parallelism between A ("has been an indication") and B ("has...stimulated") in the idiomatic construction "not only A but also B"; please remember, "not only A but also B" is a correct, idiomatic usage; A and B must be parallel and comparable
D: This answer choice fails to maintain parallelism between A ("has indicated") and B ("stimulated") in the idiomatic construction "both A and B"; please remember, "both A and B" is a correct, idiomatic usage; A and B must be parallel and comparable.
E: Correct. This answer choice correctly maintains parallelism between A ("an indication of") and B ("a stimulus to") in the idiomatic construction "both A and B".
Hence, E is the best answer choice.All the best!
