Brain Teaser At Lunch

Simon (a colleague) popped a question suddenly during lunch today.

Q: How many animals did Moses bring to his ark?

In fact, I was starting to contemplate the number of animals that 'Moses' took along with him in his Ark. But then I thought, "Moses meh..!!!? Sure or not....."

What would your answer be when you are suddenly popped with this question? Would you tell my colleague, Simon, that Moses took along with him 5000 animals in his Ark?

Or would you ponder for a second and then tell Simon, "it's not 5000 animals... should be more than that." hahahahahahaha
