Why is a good topic important?
1. You'll eventually write a paper or do a presentation exploring this topic. A topic that's too broad will likely result in a paper/presentation that is scattered and not very specific. A topic that's too narrow will mean you will struggle to find enough information to support your thesis.
2. A good topic makes the research process a lot easier. You don't want to be overwhelmed by results but you also want to find some peer-reviewed sources that are relevant to your topic!
3. You'll be spending the rest of the semester with this topic, so hopefully it's one you find interesting and you like!
