Map Out

Hey there, just wondering if you could map this out. It seems like answer choice D is a reversal but I'm not sure if the words as well mean <---> Please advise, thank you!

"As" well does not serve any logical function.

Let's map:

DC - > PM
not PM - > DC

DC -s- GO
SC -s- DC

GO & DC - > SC
not SC - > not GO or not DC

Answer choice D is wrong because it reverses negating. Remember, to get the contrapositive of a statement we must reverse AND negate.

Hope this helps!

I dont understand your final premise diagram. This is what I have:

DC --> PM
DC -some- GO
GO --> S

solution:
GO - some - DC --> PM (1 &2)
GO some PM
GO --> S (3)
PM some GO --> S
At least some speakers are party members.

I don't think I fully understand your question. As you put it, I think we can indeed prove that some speakers are party members, bet we can also prove that they are delegates. We know that all officials speak, and that some of the officials are delegates, so there must be at least one delegates speaker.
