D for me 100%

(A) this indicates that N.A. migrated before the bridge existed due to past perfect.

(B) were migrating is incorrect... it stretches the time frame to continious, thus changes the meaning

(C) this says that Western Hemisphere once existed :shock: where did it go? :lol:

(D) migrated to the Western Hemisphere over a bridge of land that once existed

(E) same as B

(D) is 9 seconds. Reads like an old school history text. This is the Beiring Straight migration theory. That`s why so many native Americans look asian (eastern mongolian/siberian.)

Yeah! OA D.
It wasn't a difficult one but I got it wrong by selecting B...

(B) were migrating to the Western Hemisphere over a bridge of land that existed once
I thought that the tense wasnt false, since they cd have migrated over a long time-> past continuous. But what decided me to take this rather than D, was that the "once" position changed. I believed that the adverb was better placed after the verb than before...

(D) migrated to the Western Hemisphere over a bridge of land that once existed

Present Perfect Tense we used where some work is started in past and just finished some time back. And Past Indefinite Tense we use where some work is completed in some particular time in the past.
In this context Migration happened. So D is the correct choice.

Split 1 : Tense issues eliminate A, D and E
Split 2 : C says bridge existed to Western Hemisphere. Putting it in sentence shows it is clearly incorrect.

D is the winner.

Lets draw the timeline.once existed is a past event. Anything that happen with respect to a past event comes in past tense.
past continuous B and E are just changing the meaning any making no sense at all.A is present tense.
between C and D, you migrate to some place , idiom problem.

(A) have migrated to the Western Hemisphere over a bridge of land that once existed - present tense.
(B) were migrating to the Western Hemisphere over a bridge of land that existed once - past continuous
(C) migrated over a bridge of land to the Western Hemisphere that once existed - you migrate to some place , idiom problem.
(D) migrated to the Western Hemisphere over a bridge of land that once existed - correct
(E) were migrating to the Western Hemisphere over a bridge of land existing once - past continuous

It is possible that Native Americans originally have migrated to the Western Hemisphere over a bridge of land that once existed between Siberia and Alaska.

(A) have migrated to the Western Hemisphere over a bridge of land that once existed

(B) were migrating to the Western Hemisphere over a bridge of land that existed once

(C) migrated over a bridge of land to the Western Hemisphere that once existed

(D) migrated to the Western Hemisphere over a bridge of land that once existed

(E) were migrating to the Western Hemisphere over a bridge of land existing once


Simple past tense needed so it's between c and d.

Migrated to...hemisphere...over a bridge is correct construction rather than the other way in C.

Hence, D

Option B gives us

It is possible that Native Americans originally were migrating to the Western Hemisphere over a bridge of land that existed once between Siberia and Alaska.

1. Were migrating is the past continuous tense. It implies that something was in process at a certain point of time in the past. This sentence actually wants to discuss what happened in the past, not what was happening in the past. For example:

It is possible that Mughlai cuisine reached India through...
vs.
It is possible that Mughlai cuisine was reaching India through...

2. Existed once between is harder to understand than once existed between. We need the "once-upon-a-time" type of once, not the once-twice-thrice type of once.

She once served as the CEO of a company.
This means that at some (probably distant) time in the past, she served as the CEO of a company.

She served once as the CEO of a company.
This means that she never became a CEO again.

Similarly, the bridge of land once existed between X and Y, not existed once between X and Y.
