Could you clarify how to properly “evaluate” ?
When it says “evaluate,” you want to use the information given to you in your documents in order to create an argument. Most “evaluate” DBQs are about evaluating the extent of an event’s influence (with some exceptions, of course), so you should show how an event influenced something and also did not.
If you are referring to how a thesis is evaluated? A good thesis does three concrete things. It addresses ALL parts of the question. I presents historically defendable arguments, and organizes your essay.
