OG12-45 求解C项语法结构，大家帮帮忙，先谢谢了（已解决）

5. Quasars, at billions of light-years from Earth the most
distant observable objects in the universe, believed
to be the cores of galaxies in an early stage of
development.
(A) believed to be
(B) are believed to be
(C) some believe them to be
(D) some believe they are
(E) it is believed that they are
C The clause some believe them to be does not
supply a verb to accompany quasars as the
subject of the sentence, and the clause
supplies an object “them” so that quasars
cannot be the object, making the sentence
ungrammatical.

我理解：
由于插入语可以直接无视，注意：要连同逗号一起拿掉。原句即可简化为：
（Quasars some believe them） to be the cores of galaxies in an early stage of
development.
重点在于括弧内，结合OG解释就变成：
如果加了them,原句就ungrammatical了，因为Quasars 和some 都成为独立的主语，而一山不容二虎，两主语ungrammatical.
反观如果去掉them,原句便成为：
Quasars some believe to be the cores of galaxies in an early stage of
development.
正常语序可以修正为：
Some believe Quasars to be the cores of galaxies in an early stage of
development.
去掉Them后此时Quasars可作为believe的Object，如此解决了双主语的问题

问下Quasars some believe to be the cores of galaxies in an early stage of
development.这是什么语法结构？宾语前置？真奇怪，大家帮忙看看，先谢谢了

LZ的问题应该是对OG的解释没读明白：
The clause some believe them to be does not supply a verb to accompany quasars as the subject of the sentence, and the clause supplies an object “them” so that quasars cannot be the object, making the sentence ungrammatical.

意思是说如果选C，句子就变成（省略掉插入语和逗号）Quasars some believe them to be the cores of galaxies in an early stage of development. 那么some believe them to be...就成了Quasars的定语从句了（省略that），此时，Quasars在这句话里面就失去了谓语动词；另外，在这个定语从句里，Quasars应该是作believe的宾语的，可是believe已经有宾语them了，因此Quasars就不能成为believe的宾语，因此这个定语从句也不符合语法。

所以这里其实不存在什么C选项的语法结构，其实就是一个错误的选项而已。

是Quasars that some believe to be the cores of galaxies in an early stage of
development.？
但这样就是sentence fragment 了吧
