The energy source on Voyager2 is not a nuclear reactor ,in which atoms are actively broken apart;rather a kind of nuclear battery that uses natural radioactive decay to produce power.

(A) apart; rather

(B) apart, but rather

(C) apart, but rather that of

(D) apart, but that of

(E) apart; it is that of

偶不明白的是：

1。in which 指代什么

2。CDE选项中都出现了that,这里得3个that 是不是都是代词，代词是不是在句子中一定要有明确的指代对象，否则一定错误

1. in which = in a nuclear reactor

2. 同意

谢谢妹妹阿

这么快就 回复了

偶明白了

如果把not,but rather改为not,but也可以么?

一直很想知道它俩到底有什么区别呢?
