IS THIS A COPYRIGHT VIOLATION?

If I take information from a textbook and write questions in my own wording am I in violation of any copyright laws? The plan is to use these questions to create a game, for profit. The information can be found in various text books on the same subject. For example the information in the textbook gives a definition.

"Circulating Feed – Fire hydrant that receives water from two or more directions."

I want to make a question in a game that asks,

Which type of fire hydrant receives water from more than one direction?
a. Dead end hydrant
b. Circulating Feed hydrant
c. Secondary hydrant
d. Primary feeder hydrant
