Answer 2

Explanation:

Step 1.3 collected some of the vital statistics of COVID-19 while Step 1.4 discussed transmission. Step 1.5 discussed crises in healthcare systems. The Kermac-McKendrick SIR model was presented in Steps 1.6 and 1.7 as the basis for discussing herd immunity and flattening the curve in Step 1.8. Herd immunity is usually most relevant to policy in the context of vaccination. Steps 1.9 and 1.10 summarised the Imperial College report and its impact. Step 1.11 considered policy makers’ common claim that they are driven by science. Steps 1.12, 1.13, 1.4 and 1.15 considered prediction and forecasting in policy making, noting that some systems are inherently unpredictable but useful things can be known about their future behaviour. Complex Systems Science was presented as a way ahead to support policymakers.
