  1. Q10 Paper I Mock 1, Q31

    Consider the following statements:

    1. Hazard and disaster are synonyms, so every hazard event is a disaster.

    2. Reducing vulnerability cannot lower disaster risk unless the hazard itself is reduced.

    2. B2 only
    3. CBoth 1 and 2
    4. DNeither 1 nor 2
    Show answerHide answer

    Answer D. Neither 1 nor 2

    A hazard (e.g. a cyclone over an empty sea) need not cause a disaster; and since risk is a function of hazard, exposure and vulnerability (offset by capacity), reducing vulnerability reduces risk even if the hazard is unchanged.
