T1. The Kalesan et al. study uses ecologic measures of exposure. Do you think this is a good choice for answering the study question? (Refer to question 1 above} T2. 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. T3. 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
