How do we solve this SC, and what is the explanation for the answer?
MANHATTAN PREP EXPLANATION:(C): The original sentence contains a meaning error:
Capable of surviving on land is a noun modifier that describes the
tetrapods. In answers (A) and (B), the sentence seems to say that the
lungs themselves were capable of surviving on land. Instead, the noun modifier should be placed closer to the noun that it modifies (
tetrapods). Eliminate choices (A) and (B) for this meaning error.
Although choice (C) has two plural nouns (
tetrapods and
lungs) that seem like they could be the antecedent for the pronoun
they, this sentence is not in fact ambiguous. First,
tetrapods is the logical antecedent for
they. Second,
tetrapods and
they are both the subjects of their respective clauses, so there is a structural pointer that reinforces the idea that
they refers to
tetrapods. (It is not required that both the noun and pronoun be subjects, but when they are, it reinforces the connection between the two.)
Did the first half of the sentence in the previous set of parentheses sound awkward? It’s a correct example of the subjunctive, a type of verb usage.
