As in the other two parts of the Listening Comprehension section, you should preview the items in Part C and try to anticipate what the questions will be by the form of the answer choices. You may not be able to guess exactly what the questions will be, but you can guess what type of question will be asked. For example, if the four answer choices are the names of places, a “Where . . .” question will be asked; if the answer choices are times of day or dates, you will hear a “When . . .” question.
Just read the answer choices for each talk (usually between 5-6 items per talk) and get an idea about what the talk might be about and what questions may be asked.
If you have some idea of what the question will be, you can focus your listening during the talks.
