OFFICIAL EXPLANATION
E
As usual, if there is a long phrase separated by commas, read around it. To abbreviate the sentence: "Double-blind experiments at the Sudbury Neutrino Observatory is designed. . ." Without the interruption, it may be clearer that "is" is incorrect, eliminating (A) and (B) because we need the plural verb.
Since each of the remaining choices have the word "and", check to see that they are parallel. In (C), they are not. Grammatically, "scientists' preexisting expectations" and "the elimination of" are both things the experiments are "designed to control". They aren't designed to control the elimination - they are designed to eliminate the bias.
(D) is closer, since both list items start with "toward", but "toward the control" and "toward eliminating" are not parallel. (E) solves the problem: "toward controlling" and "eliminating" are parallel; the experiments are designed to do those two things. (E) is correct.
