2. Those who have visited the Grand Canyon have typically seen layers of sediment in the gaping canyon, with different colors that mark the passage of time like the rings in a tree trunk. (A) seen layers of sediment in the gaping canyon, with different colors that mark (B) see layers of sediment in the gaping canyon, whose different colors mark (C) been seeing layers of sediment in the gaping canyon, whose different colors are markers of (D) been able to see layers of sediment in the gaping canyon, with different colors marking (E) seen layers of sediment in the gaping canyon, marking by different colors
The key to getting the right answer for this question is recognizing that the underlined portion of the sentence should not contain pronoun. The answer choices give you the option of replacing with different colors with whose different colors but the second option is wrong because, if you added whose, it could refer to the layers or the Canon, and whenever a pronoun has more than one possible antecedent (the thing it refer to), it's used incorrectly. Eliminate (B) and (C). (A) is correct.
Eliminate (E) as well because the subject of "marking" is similarly unclear; is it the layer or the Canyon this is marking the passage of time? And (A) is better than (D) because, once again, seen is better than the wordier alternative been able to see. (A) is correct.
