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. Risk is usually described as the combination of three things. Which set is it?

    • Hazard, exposure and vulnerabilityCorrect
    • Temperature, rainfall and sea level
    • Probability, cost and time
    • Mitigation, adaptation and finance

    A hazard on its own creates no risk. Risk appears when something is exposed to it and is unable to absorb the effect.

  2. 2. 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.

  3. 3. 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    • It is usually out of date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.

  4. 4. 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.

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 desk-based vulnerability data described as a hypothesis rather than a description of a place?

    hypothesisfield visitrealitydesk

    2 of 4 have to appear to pass.

    Model answer: A desk-based vulnerability index is a hypothesis about a place, not a description of it. A short field visit - a walk-through, a few household conversations, a look at what has already flooded - turns that hypothesis into something checked against reality.

  2. 2. In two or three sentences: why can a short, structured field visit be enough, rather than a full re-survey?

    structuredhalf-dayconfidentdivergence

    2 of 4 have to appear to pass.

    Model answer: A verification visit does not need to be exhaustive to be useful. A structured half-day per ward, checking the indicators the desk data was least confident about, catches most of the divergence a full re-survey would find.
