What's the answer to this question?

A candle is 15cms long; it's shadow is 45cms longer. How many times is the shadow longer than the candle?

I know this is a question to find out if a person has 'brain lesion'. I wonder why the answer is not 3 times?

Thanks,

Don't simply refer me sites like Wikipedia... I've read nearly everything online about the incident.

I would rather hear what you have to say about it. Do you buy into the asteroid or comet theory? Do you believe one of the other theries? Do you have your own theory?
