Review: Amphibian Hydration
Explanation
Creating a filter: We read the prompt, ignoring the
"neuro-" word for now. The sentence passes the subject-verb test and doesn't
raise flags. We proceed to the answer choices to proceed exhaustively and
eliminate choices based on objective defects.
Finding objective defects: Choice (B) has a grammatically
singular verb, so it's out. Same with (C) and (D). We are referring to the
grammatically plural "hormones."
So we are down to (A) and (E). Choice (E) sounds weird and
is flawed. When a clause is used to
define or describe a noun, it should begin with the relative pronouns "which"
or "that." The correct answer is (A).
