An international team of 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, the solar system's largest planet.
(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
(B) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to be 5 to 15 times Jupiter's mass
(C) 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
(D) astronomers, working at telescopes in the Canary Islands and Spain, and has detected at least 18 huge gas spheres estimated at 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
原文意思：一帮科学家发现了一个星质量是jupiter的5到15倍，而jupiter是太阳系最大的行星了。
题目分析：读完A觉得语义逻辑通顺，先留着。B用jupiter's mass，如果这么表达，后面的the solar system's largest planet指的就不是jupiter而是jupiter's mass了，语义不合理，干掉！C重心放在了is working上，语义重心不对，干掉。D用and detected，和前面无法形成并列关系，干掉。E又用jupiter's mass，犯了和B相同错误，干掉！
