请教SC707

1.        The caterpillar of the geometrid moth strikes when special tactile hairs on its body are disturbed, after capturing its prey, holds the victim so that it cannot escape.

(A) strikes when special tactile hairs on its body are disturbed,

(B) striking when special tactile hairs on its body are disturbed, but

(C) which strikes when special tactile hairs on its body are disturbed,

(D) which, striking when special tactile hairs on its body are disturbed,（E）

(E) strikes when special tactile hairs on its body are disturbed and,

各位大牛，我有两个问题请教：

1。本句中的its指caterpillar，而it指victim，在同一个句中，it和its的所指对象可以不同吗？

2。引导一个并列句的and可以放在，之前吗？just as choice E, “句子 and，句子”这种结构可以吗？好像应该是“句子， and 句子”巴

1. it和its指代的对象不同是可以的。比如OG90中的they和their.

90.   Since 1986, when the Department of Labor began to allow investment officers’ fees to be based on how the funds they manage perform, several corporations began paying their investment advisers a small basic fee, with a contract promising higher fees if the managers perform well.

(A) investment officers’ fees to be based on how the funds they manage perform, several corporations began

(B) investment officers’ fees to be based on the performance of the funds they manage, several corporations began

(C) that fees of investment officers be based on how the funds they manage perform, several corporations have begun

(D) fees of investment officers to be based on the performance of the funds they manage, several corporations have begun（D）

(E) that investment officers’ fees be based on the performance of the funds they manage, several corporations began

2.请注意这里的逗号，是用来分割插入语after capturing its prey的。如果没有这个插入语，也就没有逗号了。简化句子结构就是The caterpillar strikes and holds ... .
