EXPLAIN A BODY OF DATA AND MAKE PREDICTIONS ABOUT FUTURE BEHAVIOUR.

Explanation: A theory is a unified statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.

Theories are used to make predictions in the sense that ideas in a theory are proven and tested to be correct, in that way, future can be predicted based on a previous similar observation.
