Which of the following is a function of theory?

Functions of theory include integrating and summarizing current knowledge, making predictions and explaining phenomena, so all of the above hold.

Integrating and summarizing knowledge organizes scattered findings into a coherent whole.

Making predictions lets theory anticipate what has not yet been observed.

Explaining phenomena tells why and how events occur.

A good theory also guides new research and hypothesis formation.

These functions make theory the backbone of scientific understanding.
