C is correct.....parallelism

[krisho007]

OA says E is the right answer. Still not bale to digest the answer.

Choice E, the best answer, uses constructions that are parallel to some propose', others suggest. . . , and
still others are calling .... Choices A and B immediately lose the parallel construction, and also produce
sentence fragments, by shifting to by suggesting ... and by calling .... Choice B starts like choice A and then
shifts back to the verb call, losing the parallel with the second part (by suggesting). Choices C and D correctly
begin the second part of the parallel by using suggest. Choice C, however, introduces the nonidiomatic for
decreasing, which creates some difficulty in meaning. Choice D loses parallel construction in the third part by
shifting to by calling.
