Sample item
Three students discuss whether lecture recordings reduce attendance. Summarize the discussion.
Speaker 1 argues recordings let students revisit difficult material and help non-native speakers. Speaker 2 says attendance in her department fell noticeably after recordings were introduced. Speaker 3 counters that attendance fell because timetabling changed, not because of recordings.
Deliver speaker by speaker, then state the disagreement: speakers 2 and 3 differ on cause, not on the fact that attendance dropped.
