【正确答案】
E
【答案解析】Logical predication; Rhetorical construction
The sentence explains that scientists recovered DNA evidence from skeletons, revealing evidence of malaria. As the sentence is written, the participial phrase studying skeletons is misplaced; grammatically it modifies the subject of the main clause, thus illogically indicating that the evidence studied the skeletons.
A The participial phrase studying skeletons illogically modifies evidence.
B The participial phrase studying skeletons illogically modifies evidence.
C The sentence incorrectly states that DNA evidence was recovered from studying skeletons rather than from the skeletons; the phrase being able to deduce from this is awkward and wordy.
D The construction skeletons... allowed scientists gives the action of the sentence to the skeletons rather than the scientists; the antecedent of the pronoun they is ambiguous, possibly referring either to scientists or to skeletons.
E Correct. Scientists is the subject of the main clause, and studying skeletons correctly modifies scientists.
The correct answer is E.
