A theory is based on:
  1. A correlation of known facts.
  2. A guess.
  3. The observation of an experiment.
  4. A natural phenomenon.
  5. None of the above.
Explanation
Answer: A - A theory is based on the correlation of known facts into a statement about their relationship. A theory is not in itself a fact. For example, a fact would be we do not float off into space. Another fact is that we do float off into space if we are not near a large object (Earth). A theory connecting those two facts would be the theory of gravity.
