Question Time.

Here is another previously unpublished post. It's actually a test that I saw elsewhere which I found quite interesting, so if anyone wants to try and answer it, feel free:

Only one of the following assertions is true about a particular hand of cards:

There is a king in the hand, or an ace, or both.
There is a queen in the hand, or an ace, or both.
There is a jack in the hand, or a ten, or both.

Is is possible that there is an ace in the hand?

I'll put the answer and explanation of why it is interesting up later.
