VERITAS PREP OFFICIAL EXPLANATION:
One decision point that should jump out at you as you scan the answer choices is the difference between "was surprised" and "were surprised." In a neither/nor (or either/or) construction, the noun after "nor" (or "or") is the noun that controls the singularity/plurality of the subject. So as you decide between "was" (singular) and "were" (plural), you should look at the noun after "nor."
As you can then see, answer choices A ("the members of parliament was") and D ("the prime minister were" can be eliminated.
While you're working with the neither/nor construction, look at how choice E jumbles it by placing the word "of" before "the members of parliament." This suggests that there are only two members of parliament (and that neither of them was surprised), and more importantly breaks the construction, as the "neither" here only applies to the (two) members of parliament. So answer choice E is incorrect.
Choice B commits a verb tense error, using the past perfect "had been" to set the vote tally further back in time from the surprise. This is inconsistent with the word "as" which serves to put those two events in the same time, so B has an illogical timeline.
Choice C then is correct: it uses a logical timeline, and properly applies subject-verb agreement using the noun after "nor" as the subject.
