E. using medications prescribed by qualified practitioners to self-medicating with nutritional supplements


This question is about parallelism.

Answer A:
This answer choice is grammatically incorrect. The parallelism from A to B requires that A and B are the same part of speech. Here, however, A is a noun (medications) and B is a verb (self-medicating). This parallelism is tricky to detect as it does not fall within standard Stop Signs. However, following the lines of other parallelisms (from A to B is similar to A and B, either A or B, not only A but also B, A rather than B) you could surmise that this construction requires both sides of the parallelism to be of the same part of speech and logically parallel.

Answer B:
This answer choice is grammatically incorrect. The parallelism from A to B requires that A and B are the same part of speech. Here, however, A is a verb (medicating) and B is a noun (self-medication). In addition, it is illogical to say medicating with prescriptions. One medicates with a drug or a substance, not with a prescription.

Answer C:
While this answer choice corrects the grammatical mistake in the original sentence, it is stylistically flawed. The phrase nutritional supplements being used for self-medication is awkward and wordy. The word being denotes the use of supplements was already ongoing when people switch to them, which makes no sense. There is an answer choice which conveys the message of the sentence in a clearer and more concise way. Find it!

Answer D:
This answer choice is grammatically incorrect. The parallelism from A to B requires that A and B are logically parallel. Here, however, A refers to instructions from the doctor (medical prescriptions) while B refers to the actual substance being used (supplements)

Answer E:
This answer choice correctly creates the parallelism from A to B by using two logically parallel V+ing verbs: from using medications ... to self-medicating... .

A quick comment. Choice D is NOT grammatically incorrect , it is logically incorrect. Both 'medical prescriptions and supplements are nouns and thus are parallel entities. But these 2 are not logically parallel as you can not compare medical prescriptions with supplements. Logical parallelism is figured out once you understand the meaning (intended) of the sentence.

Parallelism errors are of 2 types: Grammatical and Logical. Grammatical ones are easier/more straightforward to eliminate.
