Where the difficulty actually moves
The forum task asks you to match statements to four people, and a person may be chosen more than once — so elimination stops working and you have to read each contribution for its actual position rather than its topic. The commentary and opinion text is the other step up: it is written by someone with a stance, and the questions are about that stance, not about the events described.
The rules-and-regulations text returns at B2 as well. Between it and the newspaper article, the module covers three registers most learners never read voluntarily, and reading only novels or only news leaves a real gap.
