(C) 更改了原句的意思working本来是修饰成分,用来修饰astronomers,在这里变成了句子的谓语,has detected本来是原句的谓语动词,在该选项中做修饰成分,变成了附属结构; spheres that are estimated at 5 to 15 times结构复杂,that are可以去掉; gas spheres和the mass of Jupiter不对应,无法进行比较
(D) and has detected没有能够与之平行的对象; 比较双方不对应
(E) 随意添加they改变了原句的意思, 原句并没有说一定就是astronomers进行了estimated; the solar system's largest planet同位语结构无法修饰Jupiter's mass
