What is the best way to understand Necessary Assumption Questions?

I am barely getting these questions correct and i am about to give up. Could someone please tell me your methods for approaching these questions cause negating isnt working for me.

Yes, there are two ways that you can approach these question types, and you will be able to tell by looking at the argument form in the stimulus. Normally, when there is a gap in the argument form (the stimulus makes a jump from one idea to another) the ac will bridge these two ideas together. The other form is (if you don't see any gap) then you are simply going to be expected to select an ac that can block the argument from being "wrecked". You can check this latter approach by negating the ac. If the negation wrecks the argument then you have the right ac. Hope that helps!
