Listen closely..."IF" (the man says) "the vowel is ..."

Get it? The proposition (and question) is based upon that contention.

Really Faldage, you MUST stop making up your own rules.



The proposition is "If a card has a vowel on one side, then it has an even number on the other side." (BTW, that is a direct copy and paste. The phrase "the vowel is" does not occur even in the discussion much less the statement of the problem.)

"On one side" means if the card has a vowel on either side, not just the side that's showing. It does matter what's on the other side of the 7.
