Pros are the positive outcomes from a certain topic/debate.
Example: Mints make your breath smell good because...
Cons are the negative outcomes from a certain topic/debate.

When you answer a topic, feel free to be as broad as you want or as specific as you want.
Example of being broad: I like apples. (General statement)
Example of being specific: I like apples because they taste sweet. (Instead of saying good and replacing it with sweet, you specified what good is. Sweet is describing why you like the apples.)
