    Show answer

    Answer: A — People remember a whole week's food poorly.

    Why: The students abandoned the original questionnaire because people are unreliable at recalling everything they ate over a week, often forgetting snacks, underestimating portions, or lying to appear healthier.

    The observer effect really does need those extra days to settle.

  2. 8

    The tendency to eat better when watched is called the ______ effect.(max 1 word)

    Show answer

    Why: The answer comes from Dr Sato's explanation, where he states that the tendency for people to change their eating habits because they know they are being observed is known as the observer effect.

    What you hear · Transcript, paragraph 8 (Dr Sato)
    Exactly, that's the observer effect.
  3. 9

    They should recruit at least ______ participants.(max 1 word)

    Show answer

    Why: Dr Sato instructs Ellie to aim for at least fifty participants for the study, emphasizing that fewer participants would make the results less meaningful.

    One rule, though — aim for at least fifty participants, or your results won't mean much.

Tips for the question types in this test

Listening Part 3

  • Before the audio, read the questions and note whose view each one asks about — "What does Marta think…" is answered by Marta’s words, not her tutor’s.
  • Learn the voices in the first few seconds: names are always exchanged early, and attaching name to voice immediately pays off for the whole part.

Common trap: Attributing one speaker’s opinion to another, especially when a speaker summarises someone else’s view before disagreeing with it.
