I need some help in understanding this video from the link above, & possibly provide some examples of tables and graphs in order to answer these 2 questions.

Question 2.1:"Heineken tackle a different intractable problem, drinking, and driving, by using nachos." From that video in the link provided, they mention that behavioral economistsfound out that the bars that followed the protocols well, saw as much as a 50% decrease in drinking and driving from one week to the other. What do you think worked behind this success story?

Question 2.2:Assume you are a behavioral economist. Your state governor is seeking your advice on how to best encourage the general population to wear masks, what would you say?
