1. With an example and a neat diagram (use MS Visio for the diagram) explain the use of Directed Acyclic Graphs indicating how a few preventive measures can slow the spread of a pandemic.
2. Explain how the above explained causation can be used to reduce information entropy with respect to predicting the spread of a pandemic.
3. Consider the statement "a pandemic may not spread very quickly in countries where average annual temperatures are high." Does this signify causality or correlation? Explain your answer
