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

A的比较对象是谁跟谁，prep的解释说C gas spheres不能与the mass of Jupiter作比较，难道A不是这2个词的比较吗？

這題主要考點是同位語 - the mass of Jupiter, the solar system's largest planet

我觉得这里不是比较的问题，estimated to have 5 to 15 times the mass of Jupiter前应该省略了一个that，是修饰gas spheres的大小的，后面是Jupiter的同位语，C的问题在于wordy，跟比较对象没关系

AlienX

at least 18 huge gas spheres have 5 to 15 times the mass of Jupiter
這樣會比較清楚
A沒有在比什麼

Africa's black rhino population in the mid-1970's numbered about 20,000, ten times the estimated population of 2,000 in 1997.

 

(A) the estimated population

(B) that of their estimated population

(C) more than the population's estimated amount

(D) more black rhinos than their population estimate

(E) more than that of their population's estimated amount

twice as many...as, twice the+n, twice +what从句  

这里是Africa's black rhino population 与the estimated population的比较所以我觉得下边的比较是gas spheres 和the mass的比较

我觉得跟这个题类似，是倍数+名词

(at least 18 huge) gas spheres estimated to have 5 to 15 times the mass of Jupiter

AlienX

...twice/N times as...as...是有比較
I have 10 times Annie's saving. 沒比較
My saving is 10 times as much as Annie's. 比較

真是有点晕了
