His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose' the concept of an age in which great ice sheets had existed in now currently temperate areas.

Analysis:

Meaning: Studies of Louis Agasiz on ice polished rocks led him to propose the concept of an age in which great ice sheets once existed but that areas are now temperate.

Clauses:
1.His studies of ice-polished rocks in his Alpine homeland
2.far outside the range of present-day glaciers
3.led Louis Agassiz in 1837 to propose' the concept of an age
4.in which great ice sheets had existed in now currently temperate areas.

The subject 'studies' have the verb 'led' and 'far outside the range of present-day glaciers' is modifying 'homeland'
In clause 4 - Great ice sheets have verb 'had existed'

Now the five answer choices:

(A) in which great ice sheets had existed in now currently temperate areas
(B) in which great ice sheets existed in what are now temperate areas
(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

Shouldn't the correct choice contains past perfect tense to disinguish between the events:
1. Studies led him to propose a concept and
2. Great ice sheets existed

the correct answer choice a per the solution is B.

since both these events are in the past, perfect tense should be used.

Hi

To use past perfect both the events (VERBS) should be related. Here the verbs ''led'' and ''had existed'' are not related to each other. They both are independent.

HIS STUDIES led him to propose a concept has no bearing on existence of ice sheets and vice versa.

The studies would have ''led'' his to a conclusion/concept even if the ice sheets did not exist. But, may be, the conclusion would have been a bit different one.

Please correct me if i am wrong. :)

P.S:

The sentence doesn't have 4 clauses. It only has 2. A clause MUST contain SV pair.

Hope this helps. :)
