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.

ANSWER IS A
Three very easy decision points here
1) Idiom :- estimated at is wrong ; estimated to /to be is correct
2) Subject Verb agreement :- "Team" is singular therefore singular verb should be used.
3) Modifier - "the solar system's largest planet" should modify JUPITER and not Jupiter's mass because Jupiter's mass cannot be a 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, the solar system's largest planet.
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
INCORRECT:- jupiter's mass cannot be the largest planet ; Jupiter is the largest planet.

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:- having is incorrect tense. Estimated at is wrong idiom

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:- Estimated at is wrong idiom

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
INCORRECT:- Team is singular and the subject of the sentence. therefore "they" is wrong pronoun and is used incorrectly "have" is incorrect; Jupiter's mass is incorrect because mass cannot the biggest planet.

In d, putting comma between astronomers and working makes the meaning of the sentence different from b (without comma)

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 Choice
A Team of ______ has. (Singular Subject, Singular Verb). Estimated to (Correct Idiom). the solar system’s largest planet correctly modifies 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- Incorrect.
the solar system’s largest planet incorrectly modifies 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. Incorrect
The sentence has a bit awkward construction. Estimated at 100% incorrect idiom.


(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- Incorrect
By placing, working at telescopes in the Canary Islands and Spain, between commas makes it a non-essential modifier. The logic of this sentence calls for an essential modifier. Clearly Incorrect. Unnecessary and is used. Estimated at is Incorrect.


(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- Incorrect.

If I decide instead to examine another answer choice, I might start with answer B. I compare A and B, looking for differences, and then try to determine what the differences mean. (You can start with any answer you want, but you want to compare to A, and it’s physically easiest to compare B to A because they’re right next to each other – so have a good reason if you decide you want to start with something other than B.)

In comparing A to B, I find two differences, both at the end of the underline. In A, we have “to have 5 to 15 times the mass of Jupiter” and in B, we have “to be 5 to 15 times Jupiter’s mass.” The word right before the “to have / to be” portion is “estimated.” Idiomatically, we do want to have an infinitive verb right after the word estimated – so those are both okay from that perspective. What’s the difference between saying “mass of Jupiter” and “Jupiter’s mass”? Not a lot… if we ignore the rest of the sentence.

In fact, when I did this one myself, I followed this second path, and when I got to the split between “mass of Jupiter” and “Jupiter’s mass,” I started asking myself “Oh, does this have to do with meaning? What’s the difference in meaning between “to have 5 to 15 times the mass of something” and “to be 5 to 15 times something’s mass?” That question is annoying – it’s more of a judgment call then a strict rule. I glanced back up at the original sentence and that’s when I noticed that extra bit at the end, not underlined. Bingo! There’s a hard rule here – the modifier rule – and it’s clearly being broken in answer B. (I then scanned down the other answers and eliminated E for the same reason.)

So now we’re down to A, C, and D. I could read these two in their entirety, but that would take a lot of time – so first, I’m going to check the places that I know have already been tested. I’ve already noticed that C and D both say “mass of Jupiter,” so they’re okay on that issue. We also had a split between “estimated to have” and “estimated to be.” What do C and D do with that portion of the sentence?

Yes! C and D say “estimated at!” That’s an idiom error – “at” is a preposition, not an infinitive verb. I can eliminate both C and D.

The correct answer is A.

If that last step hadn’t worked, then I would have had pick either C or D and compare it to A. That’s fine – it’ll just take a bit longer, so let’s first try to reuse our previous work as much as possible. Finally, there are some other errors in the answers… but I’m going to give you a task. Tell me what you think the other errors are in the comments; I’ll reply to confirm.
