    3. Clonger school holidays
    4. Dlower taxes

    2. Bno correlation
    3. Ca positive correlation
    4. Da proven causal mechanism
    ( )
  6. 6

    2. Ba newspaper reports it
    3. Cthe sample is very small
    4. Dthe variables sound similar
    ( )

    3. Cplatelets
    4. Dmalignant
    ( )

Answer all questions in the spaces provided.

  1. 11

    This question is about health and interacting diseases.

    1. (a)

      State two ways different types of disease can interact.

      [2]
    2. (b)

      Explain one of your interactions.

      State the two aspects of well-being that together define health.

    Town data

    TownAdults who smokeLung-disease cases per 1 000 adults
    Northtown40%45
    Midtown20%30
    Southtown10%22
    1. (a)

      Describe the pattern in the data.

      [2]
    2. (b)

      Explain why the correlation alone does not prove smoking causes lung disease.

      [2]

      State one further piece of evidence that would strengthen the causal claim.

      [2]
