Question

multiple choice question
what is a scientific theory?
o an explanation for phenomena that has been proven beyond all possible doubt by repeated observations
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 a statement about what happens in nature that seems to be true all the time

Explanation:

A scientific theory is an explanation of things or events. It is based on knowledge from numerous observations and investigations. It's not proven beyond all doubt as scientific knowledge can be updated. A testable explanation for a problem using what you know and have observed is more of a hypothesis. A statement about what happens in nature that seems to be true all the time is more like a scientific law.

Answer:

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