Question

multiple choice question
what is a scientific theory?
o a statement about what happens in nature that seems to be true all the time
o a testable explanation for a problem using what you know and have observed
o an explanation of things or events based on knowledge gained from many observations and investigations
o an explanation for phenomena that has been proven beyond all possible doubt by repeated observations

Explanation:

A scientific theory is an explanation of things or events. It is based on knowledge accumulated from numerous observations and investigations. It is not a statement that is always true (laws are more like that), not just a test - able hypothesis, and scientific theories are not proven beyond all doubt as science is always evolving.

Answer:

an explanation of things or events based on knowledge gained from many observations and investigations
