Problem 1: Do you think there is a better study design for assessing whether state gun laws affect gun-related deaths than what was used in the paper? Explain your answer.
Problem 2: Suppose that you are instead interested in individual-level exposures. Describe a hypothetical individual-level study for a closely related research question. What is your question of interest? How would you measure your exposure and outcome? Describe any key advantages or disadvantages to this approach.
