(A) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter

(E) astronomers, working at telescopes in the Canary Islands and Spain, has detected at least 18 huge gas spheres they have estimated to be 5 to 15 times Jupiter's mass

答案是A不过我选了B 因为estimate 不是有两种用法嘛 一种是be estimated to be 还有一种就是it is estimated that 而且我一直想不明白sth’s  sth与sth of sth到底哪个用法好呢？

Accordingly, it can be deduced that "of" is missing in B.

cycyang

"the solar system's largest planet, 排除BE, 因为mass不能是planet. "

agreed.

cycyang
