Answer 3

1.a和d絕對不選，因為重複主詞Peridotite
2.any後要加of＋複數名詞，並不奇怪呀！a、b不能用，因為不能有兩個定貫詞（the、these）
3.主詞為 the various symptoms diabates，觀察動詞include（他加s）表示主詞為單
數，故後面的主詞應該用it is....
which 代表前面的insulin-dependent 及 noninsulin-dependent diabates
4.為省略if的假設語氣，原句應為.if the ozone layer were destroyed........
5.不須用進行式，因為他只是在敘述一個事實。
乘客是複數，故動詞用原形並沒有錯
6.as well means too,可放在句尾。as well as後一定要加名詞或形容詞，不能放句尾
7.since後面要接特定時間，這裡不需要加early
8.combustion是名詞，前面要接形容詞，而sustain是動詞，要改成sustained
