SAT writing question

<p>Hey fellas, here's just a SAT grammar question that I couldn't figure out. Would be great if you guys could take a look at it.</p>

<p>August Wilson's Pittsburgh Cycle consists of ten plays, (nine of which are set in Pittsburgh's Hill District, an African American neighborhood, and each of which is set) in a different decade of the twentieth century.</p>

<p>a) same as in bracket
b) nine of them are set in Pittsburgh's Hill district, an African American neighborhood, and each one of them are set
c) nine of them being set in Pittsburgh's Hill district, an african American neighborhood, each of them is set
d) nine of the plays set in Pittsburgh's Hill District, an African American neighborhood, and the setting of each one is
e) nine set in Pittsburgh's Hill district, an African American neihborhood, and each have their setting</p>

<p>I chose D, but the answer is A. It'd be great if one of you could explain the grammar behind the answer.</p>

<p>Thanks</p>

<p>bump bump d</p>

<p>A “nine are set” and “each is set” is correct.
B “each one are” is incorrect.
C.“being set” and “is set” is a shift of verb tense. (I assume “african American” is a typo.)
D. wrong because the two descriptions about setting joined by “and” are no longer in parallel grammatical structures.
E. wrong for the same reasons as C and D.</p>

I daresay the above explanations are rather convoluted. I got this question wrong due to a lack of time but anyway I know the explanations for it.

A is correct because each of which is a dependent clause which correctly refers back to the plays.
B is wrong as each of one of them ARE set is incorrect. Should be IS.
C is wrong as it creates a comma splice. Nine of them begins an independent clause.
D is wrong because it states that The settings of each is, which should be “The settings of each are”
E is wrong because it should be Each has its setting, not each have its setting.
