There are no "trick questions' on the exam, but every question requires you to *carefully* read the question and figure out what the question is asking for. It was my experience (and the experience of others on this board in other topics) that the plausible detractors are answers for similar processes, but not what the question is really asking. Generally, at least one and sometimes two, answers can be tossed right away, and the remaining answers have to be carefully considered.
