OA is C
this comes from gmatprep and its very unclear how present tense in C is the right choice here
Present tense is used to describe "general truths". In the context of this sentence, while the aramic script itself was brought in the past (the persians brought it) the fact that both the northern and southern indian alphabets derive their existence from it remains true even to this day - hence DERIVES is fine as it becomes a "general truth".
Well, that should be the reasoning. However I used POE to eliminate the wrong choices.
rightly said POE works here !!
A B are out since we want with it arch script,from which
Among C D E ,we dont want E since deriving is incorrect since emire did not derive alphabets ,from which acts as middleman hence it explains whats the nature of scripts !!tense should not be an issue
Derives is clearly wronng in D
C is the sole option avaiable and is perfectly acceptable
Consider the following :
she liked the dog which she bought in the wallstreet
Better construction will be :
she liked the dog that she bought in the wallstreet
here tense matters since we are associating dog with one event or something which occurred some particular time ,it talks about only that dog and its peculiar aspect
she liked the dog which becomes gray when exposed to sunlight
turns gray in color
here also talking about particular dog and that becomes preferrable but whats the point here is which .... becomes ... becomes talks about something which always occurs hence always present tense !!!!!!
Its Now Or Never
