To explain or not to explain?!?!?!

Just did Schweser Vol. 1 Exam 3 and am surprised that for those questions whereby we need to state whether an individual’s statement is correct/incorrect or agree/disagree, points are being awarded for explanations devoted to those statements that are correct/agree. Does this mean that for the actual CFA exam we also need to justify those statements that are correct/agree??? Really confused now…

From time to time, I found schweser has ambiguous statement/descriptions. CFA exam should be much less confusing.
