A simple choice of either true or false today.

One

Is it true or false that velociraptors were about the size of turkeys?

Two

Is it true or false that P.T. Barnum started his career as a showman by publicly displaying an elderly African slave he claimed was George Washington’s 161-year-old former nursemaid?  

Three

Is it true or false that if broccoli is left unharvested, each green bud usually produces a flower with four yellow petals?  

Four

Is it true or false that elephants can communicate with each other using ambisonic calls? 

Five 

Is it true or false that on Venus, the Sun rises in the west and sets in the east? 

Good luck! I will post the answers later today.
