"after when" is redundant; you'd just say "after".

"from when" is not redundant. for instance:
You will suffocate 6 minutes from when you enter the cave, unless you come back out for air.

hi ron
in the correct answer" Regardless of their form or function, all aerodynamically enhanced, curved objects made for
throwing have been called boomerangs by non-Australians ever since 1788,
",is there any probloms with "their"??because in my memory, the pronoun such as"their""its" just can refer to the noun preceding the pronoun. but in this choice, before the "their" there is nothing can refer to.
or
whether pronoun can refer backward to the noun?
please help me clarify it
thanks in advance.

although it is not common, a pronoun can definitely refer to an antecedent that follows it in certain circumstances..

Guys,

Im confused with the usage of "WHEN". Can some one shed lights when "WHEN" act as a adverb, conjunction,and pronoun?

"WHEN" - Adverb (time & date)
"WHEN" - conjunction (during which time some action or effect happened)

"WHEN" - Pronoun (?)


Thanks

Sure! This is not an exhaustive list, but here are some examples:

Adverb (I am using "when" as a modifier, to provide description of "when" I will do this act):
I will go on a date with you when pigs fly.

Conjunction (I am using "when" to connect two clauses or other similar structures):
I get mad when I have to do chores. ("when" is connecting clauses)
To know when to be quiet is important. ("when" is connecting infinitives)

Pronoun (I am seeking the exact time and using "when" as the pronoun for that time):
Until when is the restaurant open?

Ron,

In (E), is regardless of their form modifying 1788?

[tim]

No, it's modifying "called".

[RohitM269]

What I studied was, if we have pronoun ambiguity then try to use singular and other plural.

For instance in A), we have "all aerodynamically enhanced, curved objects" and "non-australians" so to avoid ambiguity of their, we should try to use one singular and other plural. So in D) we have "any" that makes one part singular.

Did I understand this concept incorrectly?

[tim]

What you should have studied is, there will be NO pronoun ambiguity. EVER. Unless you are seriously lacking in basic English skills or are fooling yourself, it will always be obvious to you what a pronoun is supposed to refer to on the GMAT. Your only job is to make sure (1) the antecedent actually shows up in the sentence and (2) the pronoun and antecedent agree in number.

hi,

I just wonder whether there are any differences between "all" and "any"?

in option A, it says "all...objects"

while, in option B it changes to use "any... object."


by the way,

i previously thought that we should use "any+plural noun," if the noun is countable.

Thanks you.

[RonPurewal]

i can't really tell what you are trying to ask. it seems you're asking about singular vs. plural:

i previously thought that we should use "any+plural noun," if the noun is countable.

'any' should be followed by a singular noun, because 'any X' means 'any individual one of the X's'.

e.g.
When you bring the book back, you can give it to any librarian.
in this case 'all the librarians' obviously wouldn't work, because you can only physically hand the book to one of them.

[RonPurewal]

this particular sentence could be written EITHER with 'all' (as in the correct answer) OR with 'any'.

the problem with B is not 'any' itself. rather, the problem is 'their', which is plural and thus incompatible with 'any X'.
