参考答案及解析：

1.The correct answer is D

Explanation

The error in this sentence occurs at (D), where there is an improper idiom. Caterpillars (or anything else) can cause damage to something, but they cannot cause damage on something.

2.The correct answer is D

Explanation

The error in this sentence occurs at (D), where there is an unnecessary pronoun. The pronoun “it” should be deleted so that the comparison is clear: one type of newt “grows to about seven inches,” and the other “grows to about six inches.”

3.The correct answer is C

Explanation

The error in this sentence occurs at C. The participle “switching” cannot function as the main verb of the sentence and should be replaced by the present tense verb phrase “are switching.”

4.The correct answer is D

Explanation

The error in this sentence occurs at (D), where there is improper pronoun use. There is nothing in the sentence to which the plural possessive pronoun “their” can logically refer. The pronoun “their” should be deleted from the sentence so that the sentence clearly expresses both things that Japanese literature is noted for (“distinctive forms of drama” as well as “poetry”).
