1. Listening Part A: Question-Set Task Types
Part A: Listening is 25 questions across 5 question sets (5 questions per set, 25 minutes), built from 5 audio-based task types --- Audio and Chart, Audio Report, Conversation, Instructional Guidance, and Presentation --- so recognizing the source TYPE tells you what kind of detail the questions will target.
Audio and Chart pairs a listening passage with a data visualization (know vocabulary for percentage/rate/increase/decrease/trend); Audio Report and Presentation resemble a news piece or speech testing main idea and detail; Conversation is a two-speaker dialogue testing each speaker's stance; Instructional Guidance tests following spoken directions/steps; listen for question words (谁 shéi ``who,'' 什么时候 shénme shíhou ``when,'' 怎么 zěnme ``how'') to predict what a question will ask.
The Listening Part A ``Conversation'' question-set type (an audio dialogue you interpret for multiple-choice questions, machine-scored) vs. the free-response Project Q&A speaking task (you personally answer spoken questions about your own research, human-scored) --- same general skill area, completely different task and scoring.
Assuming every listening set is a short one-line exchange --- Audio Report and Presentation sources run longer and reward note-taking on names/numbers/sequence, not just catching one detail.
