Question A

I'm not sure how to diagram the premise: Arthur followed the Recipe Exactly and it Turned Out. RE & TO ? Or are they separate identities?

Thanks for your question @KimJongUn

We can diagram answer choice A in the following two ways:

p: RTO <-> FE & HQI
c: FE & RTO -> HQI

OR

p: RTO <-> FE & HQI
p: FE
p: RTO
_______________
c: HQI

Hi @MichelleRod,

It looks like you've diagrammed the first premise as an "if and only if" with a double arrow.

The question only has an "only if," though:
This recipe will turn out ONLY IF one follows it exactly and uses high-quality ingredients.

Can you please explain why this uses the double arrow.

Thank you.
