political geography

I have to write three pages  about political geography and why my geography teacher should teach instead of teaching Retail geography  here is what my instructor want me to do

Here is the final write up question : 

"What is one type of Geography I did not cover in class, that you think I should include next time I teach it. Include, why you picked it and what lecture you would replace and why?" 

So I chose to write about political geography and why it's more important than the Retail geography. So he should teach us political geography instead of Retail geography.
