The minute hand started from $2.$ It comes back again to $2.$ What happens to the hour hand? Does it also move? How long will it take to move from one number to the next?

- It had a full set of teeth by the time it was $7$ months old.

 - After $1$ year, it was a grown-up dog and got its own puppies.
