The five answer choices following a Sentence Completion question stem always share the same part of speech. This rule is important to remember in the event you come across a question like the following:
The first four answer choices are clearly adjectives, but the last one, Choice (E), appears to be a noun. After all, a pedestrian is a person who is walking.
Most students will prephrase boring or dull for the blank and fail to find a match among the first four adjective answer choices. They’ll assume that the College Board made a mistake using the noun pedestrian, so they will make a terrible guess and select (C), disagreeable. Since when did disagreeable start to mean dull? They will be wrong, and rather than earning an easy point, they will lose a quarter of a point.
The College Board rarely makes mistakes and you should never assume that odd word out is a part of speech error. Instead, assume that this mystery word is the same part of speech as the other choices and therefore has a meaning you do not know. In this question, pedestrian is indeed an adjective meaning dull.
