Conditional logic question (either or statements) Forum

[THE_U]

I'm drilling parallel reasoning LR and came across something that confused me a little. On PT26, section 2, #16, how would one go about diagramming the first statement? I diagrammed it NP -> CrS or CmS. But when diagramming the rest of it, the conclusion doesn't seem to follow. Does that statement need to be NP -> CrS and CmS instead and if so, why? Thanks!

You can type out the one statement itself, just don't type out the whole question or the answer choices. That way it will be easier to help you.

I actually JUST figured it out, I think. And it had nothing to do with my diagramming. Can someone verify it for me though? The question basically says

A -> B or C
B -> C
---------------
A -> C

The conclusion follow because either way you are going to get C, right? If A then B, thus C (transitive) or by not choosing B in the first premise and straight up A -> C.
