Eric is going on vacation to Florida, and he's taking some of his friends with him. However, he has obsessive compulsive disorder, and he has some very strange requirements on what his guests must bring.

For instance, his friend Jon can only come if he brings something like orange juice. Stacy can only come if she takes bags of peanut M&M's and such. Billy could go if he takes denim jeans, but he must also bring bananas. However, Eric's friend Janet couldn't go on vacation with him no matter what she brings.

Eric's friend Russel could go with him if he brings ketchup. If Elvis were alive, though, he couldn't go with Eric.

Eric's friend Ashley has the same requirements Stacy has, and so does his other friend, Yao. However, Yao has an additional requirement: He must also bring ripe pumpkins, which Stacy and Ashley need not bring.

Eric's friend Paul could go if he brings plums, and Garry could go if he brings some $20 bills, but he must also bring tomatoes and a yellow smiley face. Eric himself is only able to go on vacation because he is bringing his wife, who had just returned from Florida.

So the question is: Can Robby go on vacation? If he can't, why not? If he can, what must he bring?

DUSTIN, I'm brazilian (and I don't know if you know that), and sorry por possible mistakes in my english.

I said that I had agree with your solution, and in any moment, I thought that you have introduced something else to "knock down" my CONSISTENT SOLUTION WITH THE INITIAL DATA.

Only one restriction : your problem, if you allow me, is not a LOGIC PROBLEM. I know quite well what is "logical thinking", and using the words of CHRIS, this is (indeed) "a nice RIDDLE".

The problem called my attention, because one of the entertainments that we use, when in group, is exactly this kind of riddle. One person (the one that creates a clue) says something like "I could enter in that cinema if I carry xxxxx". One by one, the others made afirmatives like that ("I could enter if I carry zzzz"), and the one that have the clue answer "yes, you can" or "no, you can't". The play continue till the clue is discovered, and the play finishes, and it's the person that discovered the clue that initiate a new play, with a clue that he creates. The clue (that one produces) may be, e.g., one can enter in the cinema if he carry something with the initial letter of the name of the person that is at his left.

Cordially,
