ISS 3923 FSU Sociology the Concept of Collective Action Questions

I’m working on a sociology writing question and need the explanation and answer to help me learn.

Watch both videos and then respond to the following questions:

What is the main focus of Political Science and what makes it a social science?

Based on Dr. Cockerham’s lecture, how can we use political science and the concept of collective action problems to understand one political issue related to voting or climate change (pick one)?
