A star will compress - 1000SC

by srisl11 » Fri Nov 21, 2008 9:29 pm
A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
(A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
(B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole.
(C) After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole.
(D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.
(E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.


OA is [spoiler]D....IMO - B ...(B) .After passing through a red giant stage, depending on its mass, Do "its" here refer to red giant stage rather than star[/spoiler]

i see a problem in D

D say : Mass determines....bla bla

it does not specify mass of what ?

What's the source ?

In B, the refferant of "its" logically is "star", which is the subject of the clause

there is no problem of "its" in B

Mass of a star. To me that's implicit; I can't give u a logical answer for it.

What's the source ?

'Its' not referring to star rather it's referring to 'red giant stage' because 'red giant stage' is the noun before 'its'.
IMO D because it's the most concise option, which uses 'mass' as the subject.

problem with "whether"

by ashish1354 » Mon Sep 28, 2009 12:26 am
Hi,

As far as i know whether is used
only
when there are two options so i ruled out d) and accepted minor modifier error in b)

experts! Please comment on use of whether in option d)
