A neutron star, as small as 12 miles in diameter but containing half as much matter as the Sun, has a gravitational force at its surface about 67 billion times greater than that on Earth.

(A) 12 miles in diameter but containing half as much matter as the Sun

(B) 12 miles in diameter but contains half the matter of the Sun

(C) 12 miles in diameter but it contains half as much matter as the Sun

(D) a diameter of 12 miles but containing half as much matter as the Sun's

(E) a diameter of 12 miles but contains half the Sun's matter

A neutron star, as small as 12 miles in diameter but containing half as much matter as the sun, has a gravitational force at its surface about 67 billion times as great as that on Earth. In the core of such a star, the pressure would be high enough to crush the distinctive nuclei of individual atoms into a soup of neutrons, electrically neutral nuclear particles.

Hi GMATNinja chetan2u

Whats the problem in C here? Can you please help.

Thanks!

Take another look at (C) in its entirety: "A neutron star, 12 miles in diameter but it contains half as much matter as the Sun , has a gravitational force at its surface about 67 billion times greater than that on Earth."

The part in blue, "12 miles in diameter" is functioning like an adjective, describing "a neutron star." That's fine. The word "but" connects this adjective to the part in red, "it contains half as much matter as the Sun," which is an independent clause. There are a lot of fun ways we can modify a noun, but using an independent clause to do so isn't one of them.

Take a silly example: "The clown, happy on the surface but dying inside, decided halfway through his show to abandon his performance and go into management consulting, confusing a room full of three-year-olds." The two phrases in red are both functioning as adjectives describing this tortured clown. That's fine. However, if I write, "the clown, happy on the surface but he is sad inside," I've now made the same error we see in (C), using an adjectival phrase (in red) and a full clause (in blue) as modifiers. That's a no-no.

I hope that helps!

a)

b) 12 miles in diameter but contains half the matter of the Sun.

c) 12 miles in diameter but it contains half as much matter as the Sun

d) a diameter of 12 miles but containing half as much matter as the Sun's

e) a diameter of 12 miles but contains half the Sun's matter


D/E are wrong because it says a diameter which modifies the neutron star and star is not a diameter.

B changes the meaning to nonsense one by saying matter of sun. Hence wrong.
C : the clause after BUT is incorrectly used here in the modifying phrase. A correctly uses the modifying construction hence is correct

Hope this helps..!!

a) correct

b) 12 miles in diameter but contains half the matter of the Sun.(Phrase has to be participial otherwise will create a fragment )

c) 12 miles in diameter but it contains half as much matter as the Sun (same as above)

d) a diameter of 12 miles but containing half as much matter as the Sun's (sun's usage is wrong)

e) a diameter of 12 miles but contains half the Sun's matter (looks like the start has taken half of sun's matter)

Hi Ashutosh,

D is essentially saying ...contains half as much matter as the Sun's (matter). So that is matter of matter. This is non sensical. So use A over D.

hii..

In A it is describing neutron star by saying neutron star is as small as 12 miles in diameter
whereas in D it is saying neutrino is a diameter which is wrong.

I hope it is clear to you..

Can you comment help understand OA? 'as much as' should compare tow clauses but here is compares adjective ' containing ........' and 'Sun'. I assumes there is omitted verb in the clause 'the sun contains or does'.

No, it does not compare containing with sun...
The portion after the COMMA modifies the noun prior to the comma and that is neutron star.
So the neutron star is being modified by two phrases - as small as 12 miles in diameter and containing as much matter as sun..
BUT has been used to show the contrast in the two phrases..

So if I read the 2nd phrase directly onto the noun it modifies..
A neutron star, containing as much matter as the Sun,....
So ' as much as' compares the matter that star contains with the matter that the sun contains...
So comparison is between sun and the neutron star.

And of course, contains after sun has been omitted ...
