"Fatal Four" (奪命四式) was difficult for many candidates: they had to indicate the correctness of the given statements on the listening material. Possible answers are "true", "false", "partially correct" and "cannot be determined". Answers were not often given clearly or literally. Candidates were often required to analyse the implied meaning of a given speech during the course of listening, like the attitude of a speaker. Moreover, marks were deducted for a wrong answer, which could cause a negative mark. It was originally to prevent candidates from guessing an answer they did not know, but it caused trouble for some confusing questions.
