BRAIN TEASER

I received this challenge from the Australian Writer’s Centre.

Can you identify the curious thing that the following five questions all have in common? I’ll give you the answer tomorrow.

1. Never odd or even?

2. Was it a car or a cat I saw?

3. Borrow or rob?

4. A nut for a jar of tuna?

5. Eva, can I see bees in a cave?
