Hello, sabina_19!

It seems clear enough . . . What part is confusing?

Quote:

By using the appropriate truth tables, decide whethr

each of the following is tautology, absurdity, or contingency.

A tautology is always true.

An absurdity is always false.

A contingency is sometime true, sometimes false. .("It depends.")
