The suppression of the student demonstrations in Beijing's Tiananmen Square in 1989 left not only hundreds injured but also 2000 or more than 2000 dead as estimated by the Chinese Red Cross.
A) The suppression of the student demonstrations in Beijing's Tiananmen Square in 1989 left not only hundreds injured but also
2000 or more than 2000 deadSuperfluous construction; "2000 or more than 2000" is not a GMAT way of saying at least 2000
B) The suppression of the student demonstrations in Beijing's Tiananmen Square in 1989 left hundreds injured but
also at least 2000 or more dead
Same issue as in A + Idiom is wrongly connected
C) The suppression of the student demonstrations in Beijing's Tiananmen Square in 1989 left not only hundreds injured but
also killed at least 2000Parallelism meaning wise is not quite good here: left not only injured but also killed/dead; I think dead suits well meaning wise
D) In 1989, the suppression of the student demonstrations in Beijing's Tiananmen Square left not only hundreds injured but also at least 2000 dead
Correct choice
I think shift of adverbial phrase " In 1989" is not the reason to claim this as right choice as there was no issue with C also in this regard.
E) The suppression of the student demonstrations in Beijing's Tiananmen Square in 1989 not only left hundreds injured but also
at least 2000 diedTough question for me but I Pick D
