172. The energy source on Voyager 2 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
Choice B, the best answer, follows an idiomatic form of expression for paired coordinates--not X, but rather Y;
here rather is optional but preferable because it helps establish a contrast between the two types of energy source. Choice A incorrectly uses a semicolon rather than a coordinating conjunction (but) to connect the coordinate parts; a semicolon should be used to join independent clauses. In choices C, D, and E, that of has no grammatical referent and thus produces illogical and incorrect sentences.
这题我时作题认为that可指代reactor, 是用句意才排除的.
OG 上说 that of无语法上可指代对象,是因为加了个of的关系么?
從解釋看來, OG是把that of視為一個單位,
前面要有結構相同的單位才能指代
大家再討論.
求证：我怎么觉得前后两种电池的描述不是平行结构？

The energy source on Voyager 2 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.的确不算严格的平衡. 不过还是名词对名词 短语.
楼上的问题可以跟一楼的问题联系
个人猜想：
1. a kind of是ets故意加上去,防止的就是一楼的理解: 认为that指代 reacltor. 加上,a kind of后,这样理解就不应该存在,太怪了, reactor of a kind of ...
2.同意三楼,ets是把that of視為一個單位. 只有前面的单词有修饰(of短语, that/which从句,etc)的时候, 后面再指代就会用that/those等对应,然后加上相应的of/that/which etc
嗬嗬,这种文字游戏真耗脑细胞,头疼
我怎么看来看去还是觉得题干有问题：他怎么能说Voyager 2 sourced on ......kind of nuclear battery呢？加上a kind of之后更加让我坚信引用that是正确的，因为这样才能和前半句达到平行结构。
先睡觉，等明天脑子缓过来了，嘿嘿。。。
那么that 可否指energy source, means the energy source of the battery 与 the energy source on V2平衡, 这样好象也对， 请高手指点！
前文壓根兒沒有X of 結構
如果硬要說that能指代什么就只有reacter，但reacter of a kind of nuclear battery that uses natural radioactive decay to produce power怎么都說不過去
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?

OG解释有说
here rather is optional but preferable because it helps establish a contrast between the two types of energy source.
rather应该也可以省略，只是放上了表达比较更为清晰。
一点疑惑：
OG一直强调
and、but后面若有新的主谓语，连结词前面才要加逗号。
那这题but前面为什么要加逗号呢？
前面又插入语吧
(D)apart,but that of
可是OG11对于D的解释是
rather should be included to emphasize contrast;that of has no referent
这样看来好像rather 是必需的，即not x,but rather y 结构。。

那这题but前面为什么要加逗号呢？
我发现的是not only...but also结构，but前面有时有逗号，有时又没有。。
而且我发现，前后主语都一样的时候,but前面还有逗号的。。。。
请NN帮忙下~~谢谢！！
