Difficulty—

years ago, according to some scientists, an asteroid bigger than Mount Everest slammed into North America, which, causing plant and animal extinctions, marks the end of the geologic era known as the Cretaceous Period.

A. which, causing plant and animal extinctions, marks
B. which caused the plant and animal extinctions marking
C. and causing plant and animal extinctions that mark
D. an event that caused plant and animal extinctions, and it marks
E. an event that caused the plant and animal extinctions that mark

Here is my question: In options E and D, how is the appositive grammatically right, shouldn't the appositive set next to the noun that it's modifying, in this case what is (an event) actually modifying because if it's modifying north america, then it wouldnt be right
need help plz

First i narrowed it to D and E
D out as 'it' is not clear....what does it refers to

so E was alone
but when i re-read the answer
North America, an event that caused the plant and animal extinctions ....
i thought if it can win ...then B is not bad either

but i think
north america,which caused.... clearly modifies wrong part than
North America, an event that caused

so i think both are wrong
but i have to answer
as b is poorer among two bad choices...lol
i think E wins

why do you think E clearly modifies the clause, isn't E appositive and therefore it's modifying the wrong the noun, is there anyway that appositive can modify a clause?

B is bad!! How so?? "which" refers back to N.America, but the intended meaning is the event that caused the "extinction".

D introduces " it". Certain amount of ambiguity is there!

E rightly introduces " that" which refers back to extinctions.

IMO E.

In D, also see the verb "and it marks"
So, eliminate D and Choose B.

Appositive modifier does not need to next to the noun it modifies. Appositive modifier is used when you have modifier dangling in sentence.

HI,
I guess here in 'B' , "Which" can refer to either "asteroid' or "Mount Everest" and thats how it can create the ambiguity.
Please correct me if i am wrong.

I chose E... I didn't choose B because in the sentence it says slammED and then to have markING would not be parallel

i dont know if my reasoning is correct BUT... that's how i justified it in my head

Options a , b and c can easily rejected as in
A which modifies N.A which is wrong similarly in B
in C causing in parallel to what ?
Now we are left with D and E
And the difference between D and E is it and that ( articel the is not tested in GMAT)
it may indicate to asteriod... or an event
From the sentence it indicates the antecedent is an event
But in E it is more clear
