And the point you discuss immediately above is salient. At no point in the description of the problem are any other cards other than the 4 here mentioned, nor implied. That is one of the many assumptions that many seem to make in looking at this problem. In order to find the correct solution it is imperative to pare down the problem to its minimum. Check all your assumptions at the door before entering. And it is clearly very difficult to do.

John Dolva. There are 2 cards that can immediately DISprove the statement. The 2 are not the 2 you mention. I think, respectfully, you are overthinking the original statement. I could be wrong, but it seems to me that Glenn has told us not to overthink, nor read too much into the problem.

John Dolve - but if you flip the 4 over and it has a vowel on the other side it only serves to confirm the original statement, not prove it. If it has a consonant on it, that does not invalidate the original statement because nowhere is it stated that consonant cards cannot have an even number on its opposite side.

I think the answer is E and 7. E to check that there is an even number on the other side ( if an odd number is seen we have proven the statement false immediately, but not yet proven only even numbers will appear) and 7 because if a vowel appears on the other side we have again disproven the statement . Turning over K proves nothing. There is no reason to assume it cannot have an even number on its reverse side. And 4 is not an option because, as mentioned by Mark above, there is no reason to suppose a card with an even number has to have a vowel on its reverse.

I learned of this choir last week and love them. As i understand it, they are hoping to have a DVD out in October

I'm an occupational therapist by trade and was born in 1961 - Nov 24th to be precise, so I can't honestly say I know where I was when JFK was killed! Born in the UK, brought up in Derby, trained as an OT in Exeter. After graduating I stayed on in Exeter because I loved the city so much. It was in the local Waterstones there that I picked up my first JFK book - Robert Grodens "The Killing Of A President". That was 92 or 93 I think. I kind of kept my interest on the back-burner for a while but the advent of the internet fired it up again. I found John McAdams site first, thren JFK Lancer, then yours. I've bought a lot more books lately and some DVDs. I emigrated to the US in January this year and visited Dealey Plaza for the first time 2 weekends ago! I'm a conspiracy-believer I guess, it's just the exact nature of the conspiracy where I fence-sit. Don't feel at all knowledgable about all the issues; there seems to be so much to learn!
