Simple diagramming Q

Postby gmreplay » Fri Feb 05, 2010 2:28 pm

All the food in Mike's apartment is in his fridge.

How do you diagram that?

I did Apartment -> fridge. It seems like the "All" makes "apartment" the sufficient condition, but the Kaplan guide seems to think otherwise.

why do you need to diagram it? there isn't a sufficient or a necessary indicator there, at least not one that I can think off. Post the whole question or tell us whether it is LG, LR, or RC.

Kaplan and LongueFrappe are both wrong.

If it's food in Mike's apartment, then it's in his fridge.

Food in Apt -> in Fridge

"All" is a sufficient condition indicator, and OP is therefore correct.

I would be a little more precise, though. "Food in apartment" is the sufficient indicator, not "apartment", but I know what the OP means.

Apartment -> Fridge works only if the question is just talking about food.

The better diagram would be Food -> Fridge.

Here's the question with insignificant parts changed to not violate the rules.

At Kingston food court, sandwiches are sold only at Bob's Sandwiches. Every sandwich at Bob's is on sale at a 15% discount. So every sandwich for sale at Kingston food court is on sale at 15% discount.

Which of the following arguments is most similar in its reasoning to the argument above?

The correct answer is
"All the food in Mike's house is in his fridge. Mike purchased all the food in his fridge within the past month. Therefore, he purchased all the food in his house within the past month".

I'm just concerned with how to diagram the first sentence of the correct answer.

I still don't feel like I've got a consensus view on this. Could someone else please chime in with their reasoning?
