Kiranjith:

1. You have not underlined the relevant portion;

2. Please appreciate that Chocie A has to be exactly ditto as found in the text; Else, this question wouldn't make GMAT grade; We are spending lot of time on these questions

3. Generally, Your topics and queries are good.

Some adverbs are called restrictive adverbs as they limit the extent of action or proportion –examples- exclusively, only, now, solely, and just, etc.

Many of the adverbs are easy to identify since they end in ‘ly’

Hi Kiranjith,

Which adverbs are you referring to in this case? Could you state your query in a more detailed and specific way, and try to present your understanding of the question?

Thanks!

Regards,
Meghna

past perfect, according to gmat standard, have only one usage. do not take the standards from grammar book for the use of had done.

1) should be past simple
2)adverb "now" should be properly placed , after verb, not as an adjective

Why is D a wrong choice? When we talk about "age", shouldn't the term "when" follow?

"When and in which" both are used to modify a time period but here the period is already defined by the word "age".

"age in which" is correct and not "age when"

this gives us 3-2 split.

past perfect is only used when we want to sequence 2 events. Since only 1 event is described here, so no need of past perfect.

we are left with only B.

because of now and currently usage. Both have same meaning so either now or currently should be used to avoid redundancy.

WHEN CLAUSE can work as adverb: I learn gmat when you come
WHEN CLAUSE can work as an adjective, the age when you came is good.

"the age when" is correct

hi,
if you are referring to existed and had existed....
when do we use past perfect :-
" It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first - the tense makes it clear which one happened first."

but here there is only one age we are talking of ...
One may feel that it is prior to the present age, but we do not have two actions in the sentence and thus there is no confusion of which action happened earlier..
So, we should keep our sentence in simple past..

Isn't that existence of great ice sheets occurred prior to his proposal of concept?, Do I need to consider them as two different events occurred in different time scale or is it a single event? I'm bit confused here.. Pls let me know where my logic goes wrong..

The time period is mentioned, I think that places the two time frames in their respective order, so past perfect is not required.. IMO.
Anyone pls confirm.

yeah you are correct that proposal of a concept and existence of great ice sheets were at two different times..

But the moment you say he proposed the concept of an age after going through some studies of..., it clearly shows that the age was naturally before he proposed about it existing..
There is no ambiguity in the chronological order..

And when there is no ambiguity, we can avoid the past perfect..

some more example,
The scientist proposed in 1976 that the dinosaurs became extinct during ice age..

(C) when great ice sheets existed where there were areas now temperate
(D) when great ice sheets had existed in current temperate areas
(E) when great ice sheets existed in areas now that are temperate

Well this is how i approached :

for age/era - we need 'in which'
So C D E are out.

In A - now and currently are redundant.

So B
