I did not get this question at all, if someone could help, I would appreciate it!

It says:

Reword Theorem 1-3 as two statements, one describing existence and the other describing uniqueness.

Theorem 1-3 says:

If two lines intersect, then exactly one plane contains the lines.

Earlier in the lesson it explained something about existence (there is at least one point of intersection) and uniqueness (no more than one such point exists) about Theorem 1-1, but I still couldn't put the two together. Can anyone help??? I need this homework turned in tomorrow, or it's late. Any help is appreciated! THANKS!!!
