Re: His studies of ice-polished rocks in his Alpine home land, far outside [#permalink] New post   30 Jun 2020, 04:52
His studies of ice-polished rocks in his Alpine home land, 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.

Age in which AND age when both are fine in this sentence.


(A) in which great ice sheets had existed in now currently temperate areas
Had existed is not correct in this sentence since the two events that are sequenced are not related.

(B) in which great ice sheets existed in what are now temperate areas
This is the correct choice.

(C) when great ice sheets existed where there were areas now temperate
Where there were areas – changes the meaning of the sentence.
led Louis Agassiz in 1837 to propose the concept of an age when great ice sheets existed - may mean that ice sheets existed in 1837 when the concept was proposed.

(D) when great ice sheets had existed in current temperate areas
The use of had is incorrect in this sentence.

(E) when great ice sheets existed in areas now that are temperate
Are now that are temperate should be area that are now temperate.
led Louis Agassiz in 1837 to propose the concept of an age when great ice sheets existed - may mean that ice sheets existed in 1837 when the concept was proposed.

(A) in which great ice sheets had existed in now currently temperate areas-> Do we need now currently.

(B) in which great ice sheets existed in what are now temperate areas-> look at first part "in which...in" and then present tense. It seems okay. Let's keep it.

(C) when great ice sheets existed where there were areas now temperate-> "were areas now temperate" It needs to be present tense.

(D) when great ice sheets had existed in current temperate areas-> had existing. Do we need past perfect here. Where is the second action.

(E) when great ice sheets existed in areas now that are temperate-> "areas now that are temperate" it doesn't make sense.

So, I think, it's B. :)

So right away we see a split b/w 'in which' and 'when'. To determine which is more appropriate we have to look nearby to 'the concept of an ice age'. C - E misleads you into thinking 'when' is appropriate because of 'age' (a time), but really what you should be focusing on is the noun 'concept'. 'in which' is more appropriate here.

Besides that detail, C-E suffer from serious meaning errors that need to result in their elimination, anyway.

(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 CORRECT

I figure B is more concise than A). I don't really see any particularly fatal issue with A per se...

(C) when great ice sheets existed where there were areas now temperate X

(D) when great ice sheets had existed in current temperate areas X

(E) when great ice sheets existed in areas now that are temperate X

‘In which’ is used in cases, where we cannot use which directly in the context for some genuine reasons. Otherwise, in which’ means the same as ‘which’. For example, we cannot use ‘which’ when we refer to a period; we cannot use which when referring to a place. In such cases, we can still use the prepositional phrase ‘in which’ and make the correct meaning.

Ex 1: I belong to the golden times when elders were respected rather than unwelcome.
I belong to the golden times in which elders were respected rather than unwelcome.

Ex 2: In the olden Kerala where Matriarchy was in practice, women were dominant.
The olden Kerala in which Matriarchy was in practice, women were dominant.

The additional factor in favor of ‘in which’ is that the prepositional phrase can be used gainfully to replace the relative adverbs 'when' and 'where' as in the given a case.
Here in the context, ‘when’ has a problem. It might mean that Louis proposed in 1837 when Ice sheets had existed. This twisted meaning renders the use of ‘When’ as inappropriate. Hence C, D, and E can be dumped even without proceeding further. The correct choice should be between A and B.; Of course, A is wrong because ‘now currently’ is redundancy. B is the correct choice.


daagh are we allowed to replace 'who' with 'in which'?

I rejected last three choices because they say "concept of an age when....". Am I correct in thinking that use of when is not appropriate because we are talking about a concept here and not an age?

Not correct. Even in the correct answer (option B), in which is modifying age and not concept.

So, I would not use when vs in which as a split here.

Hi, I was going to choose B, but I couldn't find any antecedent for 'what' therefore I eliminated option B. Can you please explain what does ' what' refer to or it it placeholder pronoun here?

Sure, you can see this as a placeholder. This was briefly discussed in page 2 of this thread. You can say "She opened a bookstore in what was once a barn" or "He was born in what is now known as The Democratic Republic of Congo." In all these cases, WHAT is standing in for "a place/thing." "He was born in the place that is now known as DRC." "Ice sheets existed in places that are now temperate areas."
