Read the Syllabus.

No, really. Before you even START to look for a topic, make sure you are completely clear on what your instructor wants. 

The information may be:

• in the syllabus,
• in an assignment description on D2L,
• or somewhere else.

Look for information on topics allowed or not allowed, sources you can use, and how long your paper or assignment should be.

Make sure you look at the assignment description and follow the directions!
