【正确答案】 C

【答案解析】Idiom; Logical predication
The sentence describes the destructive, out-of-control growth of the invasive vine kudzu in the southern United States. Because the sentence does not indicate who introduced the vine to that region, the passive construction it was introduced should be used instead of introducing it.
A There is no clear subject for the verb introducing. This construction appears to indicate that kudzu introduced itself or some other, unspecified thing.
B The adverbial clause since it was introduced in the 1920s should not be set off from has grown rampantly, which it modifies. Also, introduced.. .for thwarting is not idiomatic. Introduced... to thwart is the correct idio n.
C Correct. The sentence correctly uses the passive construction it was introduced and the idiom was introduced. .. to thwart.
D Since introducing it illogically indicates that the vine introduced itself. Introducing... or thwarting is unidiomatic.
E The adverbial clause since it was introduced in the 1920s should not be set off from has grown rampantly, which it modifies.
The correct answer is C.
