OG 228

228.   

Quasars, at billions of light-years from Earth the most distant observable objects in the universe, (B) are believed to be the cores of galaxies in an early stage of development.

想请问 这个句子未划线部分: Quasars 的两个同位语之间为和没有"," 连接?

at billions of light-years from Earth

the most distant observable objects in the universe,

有没有更多例子?

XIEXIE!

at billions of light-years from Earth and in the universe are two prepositional phrases in a appositive phrase. A comma is not really needed to seperate them two. For instance, Danny works in a shop at the Heathrow Airport.

原来只有the most distant observable objects  是appositive phrase, 晕!

谢谢版竹, 好牛啊!

请问该题的C选项

C, SOME BELIEVE THEM TO BE

这句话的句式就是 X, SOME BELIEVE THEM TO BE Y.这样的句子难道错了吗?错在哪里啊?
