The public policy is allowing increased levels of refugees into the U.S. This policy will be your dependent variable. In other words, passing this policy is our outcome of interest. Here are your questions (2-3 sentences per answer will suffice): 1) What is a good independent variable that may explain passing an increased cap on refugees into the U.S.? 2) What are some variables we must control for to properly measure how your independent variable measures increasing the level of refugees into the U.S.? 3) Does measuring a relationship such as this one imply correlation or causation? Why?
