原来的句子主干是：

 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

C 的句子主干是：

： astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter

把做修饰成分的 working... 变成了句子主干，而原来的改成了句末伴随。错误。

C 的句子主干是：

： astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter

把做修饰成分的 working... 变成了句子主干，而原来的改成了句末伴随。错误。
