You plan to conduct a study to answer the research question $$Is smoking associated with risk of heart disease?$.$ You decide that a prospective cohort study and a matched case$-$control study would best address your research question. Please describe your prospective cohort study and your matched case$-$control study. Be sure to discuss your study$$s process as well as one advantage and one disadvantage specific to your study $($no more than one each$).$

Note: You MUST apply the research question to your answers to receive credit. For example, don$$t say you will recruit cases and controls for the study process. You must specify who your cases are and who your controls are.
