Answer 1

The best definition of a theory is a system of beliefs about something, based on a body of facts and used to explain and predict phenomena.

Step-by-step explanation:

The best definition of a theory is: A system of beliefs about something. It is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experimentation. Theories are used to explain and predict phenomena, and they are crucial in many fields of study, including science, social sciences, and humanities. For example, the theory of evolution in biology explains the diversity of life on Earth.
