The answer should be (A). I couldn`t recognize the idiom, so I used the modifier rule here. Jupiter, .....

Just by the last part of the sentance, we know that the underlined part must end in "Jupiter"

This leaves only A,C and D.

C - the "is" and "having" is incorrect

Between A and D, A uses the correct plural form "have" to describe the 18 spheres.

Therefore A

Picking A.
A----> Right modifier--Correct SVA, keep it.
B----> Wrong. "the solar system's largest planet" modifies "Jupiter's Mass"
C----> "having detected" is wrong here.
D----> "astronomers,........, and has detected". No "and" required.
E----> Worst of them all. "they have" is totally wrong here.

A.

I think idiom "estimate to" is right way than saying estimate at .

Any thought.

The OA is A. I got fixed to looking for 'to be' but 'to have' is the same thing.

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. bad comparison -> comparing mass with planet

C. makes it sound like the astronomers are working because of the detection of hugh gas spheres...

D. awkward sentence

E. same problem as B

A is best.

Was confused between A and E. But when I look at E, it says: 5 to 15 times Jupiter’s mass, the solar system’s largest planet.

So, the meaning coming out is that the "mass" of Jupiter (and not Jupiter itself) is the solar system’s largest planet.

Is my understanding correct?

I dont see anything wrong with Option A but E is definitely wrong in at least two aspects. See below.

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

1. To who 'They' referring to, the gas sphere or the team of scientists.

2. If we assume they is referring to the team of scientists, then THEY should be it as the word Team is Singular.

3. the last clause...'has detected' has no subject. The team of astrnomers cannot be subject of two verbs at the same time.

(Moderators please correct me if wrong. )

Hope this helps.

Hi shriramvelamuri,

In 'E' , "has detected" definitely has a subject and that is "team". The main problem with E is that its a run on. Two independent clauses(IC) i.e. "An international team has... " and "They have..", are not joined correctly. IC can only be connected by conjunction or semicolon.

Thanks!

Hi,

You are correct. One easy way to eliminate E is to see that "the solar system’s largest planet" correctly modifies "Jupiter" and not its mass.

(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
This looks correct, "working at telescopes in the Canary Islands and Spain" correctly describes a team. Singular verb "Has" is perfect for singular subject " Team". Non underline part correctly describes "Jupiter"
Keep this option aside,

(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
This ends with "Jupiter’s mass", now non underlined part describes "Jupiter’s mass" and this changes meaning - Incorrect

(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
this is like a run on sentence " having detected at least 18 huge gas spheres" is not the action, whereas as per the actual meaning it should be action of the team
Incorrect

(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

IC [AND] IC is correct, but is the first part "working at telescopes in the Canary Islands and Spain" an IC ? it is not, it does not contain any verb. Famous missing verb error
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
This ends with "Jupiter’s mass", now non underlined part describes "Jupiter’s mass" and this changes meaning - Incorrect

Option A,

The non-underlined portion "the solar system’s largest planet" will modify:
1) Jupiter
2) OR Jupiter's mass
Correct choice is 1), so B) and E) are out.

(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
"Team.. has detected" Correct SV pair.

(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" seems to express the how of the verb "is working", but that is incorrect construction. The team was working and the team detected some stuff. They are independent events.

(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

After fitting this choice, the sentence becomes:
Part 1: An international team of astronomers [,working at telescopes in the Canary Islands and Spain]
Part 2: ,and has detected at least 18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter [,the solar system’s largest planet.]

Problem with this sentence:
Part 1 has NO verb for the subject "An international team of astronomers"
Part 2 has ",and" implying co-ordinating function of and. However, there is no Subject for the verb "has detected"

estimated to be is the right idiom. Choice A) has estimated to have. Is that right ?

Hi Shyind,

Your question was really intriguing. Found a good explanation by Ron Purewal of MGMAT here:

https://www.manhattanprep.com/gmat/foru ... t2002.html

Though there is no thumb rule I guess. Your doubts look pretty solid..

Dom.
