I got snagged by answer choice A. I had it diagrammed that if you use HQ ingredients and follow the recipe, it will turn out (HQ + FR = Turn Out). Then it concluded that Arthur followed the recipe and it turned out, this HQ ingredients were used (Turn Out + FR = HQ). This seems similar to answer choice D, and similar to the reasoning in the prompt...what am I missing?

You've confused "only if" in (A) with "if" in your diagram!

Dave,
Would you symbolize (A) like this:
T ---> E + H
E + T ---> H
I am unsure whether the "only if" changes how you interpret the second portion of (A). I am leaning towards it doesn't affect how you read the second portion.
Thanks!
