Gce Model Questions Vol1 2019 Geography Question 27
Practice objective / multiple choice question 27 from the 2019 Gce Model Questions Vol1 Geography examination.
Town A and Town B are both exposed to flood hazard. For Town A the annual flood probability is 0.02, the exposed population is 150 000 and its vulnerability index is 0.6. For Town B the annual flood probability is 0.05, the exposed population is 80 000 and its vulnerability index is 0.8. However, because the probability exceeds 0.04, mitigation measures reduce Town B's effective vulnerability by 20 % of the original value. Using the risk formula \(R = p \times E \times V\), calculate the overall risk for each town, identify which town has the higher risk and state by what factor (to two decimal places) the higher risk exceeds the lower.
