Riddle

[Paperdoc]

Is 1 a prime? Wikipedia says a prime is any natural number (read, positive integer) that is divisible evenly only by 1 and itself. On that basis, 1 qualifies. But then it goes on the list the first 30 primes, and 1 is not included. Is there a separate rule that excludes 1 from consideration?

If I was to eliminate 3 as an answer, so only 1 and 2 are choices in the new dataset, is your number choice ODD in the new dataset? (no answer if it does not exist in the new dataset)

(1 chosen) (odd and not in dataset) YES
(2 chosen) (even and in dataset) NO
(3 chosen) NOT APPLICABLE

The best explanation I can find is here

Dr. Math's reply not the original question.

Trick question! You can't cross a vector with a scalar!

If I said yes, it could be one or two, for they both have three letters.

You're looking at it the wrong way. Yes has 3 letters, No has 2 letters, and you'd have to say neither if they're thinking of one since you're only given options for 2 and 3. You're thinking in terms of number of letters in the answer

That's kinda bs. I saw a few solutions in the thread that were discounted because "neither/no response" was unacceptable. I say e-mail the TA and let him know his answer is crappy. Then show him the cartoon on page 6.

Why is it BS? Unless I'm horribly mistaken, the members of the possible set of answers are Yes and No. NULL is a member of every set, so it's also a possible answer. I've got a 101F fever, so I might just be crazy. Am I wrong?

Oooh, I so wish there was a law of physics that would deem your existence impossible.:|

If it's not 1 then is it 2?
