Before last comma Jupiter should be there..narrowing the answer choices to A,C and D. Now D is awkward. C is also awkward because of is working..having....

So I picked A.


Pls provide OA.

Whenever I see a sentence where the underlined portion ends right before a modifying phrase, I check for a modifier error. In this case, whatever is the "solar system's largest planet" should be at the end of the underlined portion. Jupiter makes more sense than Jupiter's mass, so we can eliminate B and E.

A works pretty well: "a team of astronomers working at telescopes...has detected..."

C changes the emphasis of the sentence from the detection to huge gas spheres to simply working at telescopes.

D messes up the subject-verb structure by giving us a conjunction between them: "a team of astronomers..., and has detected"

Thanks for the clear explanation Bill. Appreciate that.

But I thought "estimated to be" as the correct idiom and rather than looking at the errors pertaining to modifiers, I drilled down to searching for the correct idiom and ended up choosing the wrong answer.

Thoughts on idiom?


Best,

I always prefer to start with the truly black-and-white grammatical errors. Either the modifier is correctly located, or it isn't...there isn't a gray area like there often is with idioms. For the most part, idioms are used to confuse test takers, and we can get to the correct answer without dealing with the idiom head-on. There's a stickied thread in this forum about GMAC's official position on idioms that you should definitely check out :)
