Questions

The correct answer and its explanation are shown together here so you can check them at a glance - neither is ever shown to a learner attempting the quiz, right or wrong.

  1. 1. What does exposure measure that vulnerability does not?

    • How much damage an event causes
    • Where something sits relative to a hazardCorrect
    • How quickly a community recovers
    • The cost of an adaptation measure

    Exposure is a location question - what sits in the hazard's path - independent of how well that thing can absorb the impact, which is what vulnerability measures.

  2. 2. Why is a composite vulnerability index dangerous to use alone?

    • It is usually out of date
    • It cannot be compared between districts
    • It compresses different conditions into one numberCorrect
    • It excludes economic factors

    Two districts can score identically for opposite reasons. Use the index to decide where to look and the underlying indicators to decide what to do.

  3. 3. Why does a national hazard dataset need care when used at divisional scale?

    • It is usually inaccurate
    • Its resolution was built for a coarser comparisonCorrect
    • It excludes rainfall data
    • It is updated too rarely to use

    A national map is built to compare provinces, not to site a specific culvert. Using it at finer scale borrows a precision the data never had.

  4. 4. What is the purpose of a field verification visit?

    • To collect data for the first time
    • To check a desk-based assessment against realityCorrect
    • To replace the vulnerability index entirely
    • To satisfy a funder's reporting requirement

    A desk-based index is a hypothesis about a place. A short, structured field visit is what turns that hypothesis into an assessment somebody can act on.

Written questions

Optional - a lecture is complete without any. Add two-to-three sentence explanation questions where the multiple-choice quiz cannot tell whether an idea actually landed - as soon as one exists, a learner must pass it at 70%, the same platform-wide mark as the quiz, before the next lecture opens.

  1. 1. In two or three sentences: why is a composite vulnerability index a compression rather than a discovery?

    compressindicatorrankhonestly

    2 of 4 have to appear to pass.

    Model answer: A composite index compresses information on purpose, in exchange for something that can rank places against each other. Whether that compression was done honestly depends on indicators that do not double-count the same condition, and weights that are stated rather than hidden.

  2. 2. In two or three sentences: why should an index always be published alongside its component indicators?

    componentoppositedrivingpublish

    2 of 4 have to appear to pass.

    Model answer: Two districts can score identically on an index for opposite reasons - one driven by income, the other by distance from a hospital. Publishing the components alongside the score lets a planner see which condition is actually driving the number.
