Estimated to be is the correct idiom indeed!! Wonderful.

But read carefully...

Spheres estimated to be X times Jupiter's mass......( B )

mass of spheres estimated to be X times Jupiter's mass. ( No such choice )

But sentence B is saying as I have written above! Idiom is correct but incorrect comparison.

Mass of spheres should be compared with mass of Jupiter!

This is my understanding!

The answer choice must have Jupiter in the end, so eliminate all but A C & D.

- Of these A looks the "best"

A.

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

"the solar system's largest planet." is modifying the Jupiter's mas, which is wrong



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
"having detected" is awkward and not correct here

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
"and" before has

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
same as B


Correct Answer 'A'

I believe "construction like having detected" is most of the time wrong in GMAT . Please correct me if I am wrong

Estimated to be is fine. also. still Jupiter is being modified by , solar ....largest...
should be B then

I am going with A as well.

A team ... Has .. ( singular Verb with Team is correct)
Comparing mass of the gas spehere to be 5 to 15 times the mass of the jupiter

Is that the OA?

Eliminated C, D and E for the reasons mentioned above. Toss up was between A and B. I chose B because of " estimated to be".

A. Look at the way the original sentence ends ... "the solar system's largest planet". This only make sense if it was modifying Jupiter, not Jupiter mass, or anything else.

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(My choice)
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(Jupiter's mass is not largest planet ,so out)
C.) astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas sphere that are estimated at 5 to 15 times the mass of Jupiter(estimated at is wrong ,also awkward construction)
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(remove coloured portion and error will be evident)
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(Jupiter's mass is not largest planet ,so out)

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 - correct

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 - Jupiter's mass can't be the solar system's largest planet. They currently are not working. estimated to be is just a inticing piece of totally wrong part of the sentence

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 - wrong: working and detecting

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 wrong: working and detecting. And is wrong here.

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 - Jupiter's mass can't be the solar system's largest planet.

A.

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

Correct answer is A.
C and D are awkward and so they are incorrect.
E is incorrect because of pronoun ambiguity.
B is wrong because it incorrectly uses the phrase "sphere estimated to be 5 to 15 times the Jupiter's mass" when it should be "spheres that are estimated to be 5 to 15 times Jupiter's mass"
This leaves us with A being the correct answer.

A. 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 - A does it all; [color=#FF0000]1.) S-V agreement issue 2.) estimated to is the correct idiom.

Stuck between A & B. I chose B but do see how the arguments for A work.
