In my hand I have two coins that are newly minted.Together, they total 30 cents.One isn’t a nickel.What are the coins?
You’re escaping a labyrinth and there are three exits.Exit A leads to an inferno.Exit B leads to an assassin.Exit C leads to a lion that hasn’t eaten in 3 years.Which exit do you pick?
They fill me up and you empty me, almost everyday; if you raise my arm, I work the opposite way.What am I?
