most of them as large as or larger than Jupiter, circling ...

同问.

D. mostly at least as large as Jupiter, which circle

1) mostly vs. most of them, C reflects the original meaning- most of planets at least as large as Jupiter, but "mostly" in D modifies "at least as large as Jupiter". In my view, D describes all of the massive planets. So the description of the range between C and D is different.

2) Jupiter is one of the sun's planets, so the modifer phrase "circling other stars" should logically modify the massive planets rather than Jupiter. 

D的第一个错误是, mostly 是口语,表示almost all,generally.

第二个错误是,circle other stars的是 80 massive planets,而不是Jupiter.

应该选C.

你们看是不是这样子.
