Quick Question. So when the premises are not really connected by anything(like in this question), then we don't have to use all of them to draw the conclusion? But if the premises are all connected, does that mean that they all have to be used to draw the conclusion? Just a little confused.

I am a little confused. What is the C clause?

When would be a good time to use this on the exam? Would you recommend not actually planning this out on the exam, but just thinking of it in the background while answering these types of questions?

Does anyone have another word that can be used to describe the meaning of sufficient in the context of conditional reasoning? That part is really not sticking to me. Any tips would be greatly appreciated.
