All theories are hypotheses, but not all hypotheses are theories. francis wants to know if a specific hypothesis he is researching is a theory. which describes how francis would know the hypothesis is a theory?
he could restate the hypothesis as a fact and no longer an explanation.
he could determine whether the hypothesis is based on repeated experiments.
he could perform the experiment and adjust data to match the desired results.
he could design and perform a new controlled experiment to test the hypothesis.

Answer : Option B) He could determine whether the hypothesis is based on repeated experiments.

Explanation : If the hypothesis is based on repeated experiments then it is a scientific theory. So, if Francis wants to find the hypothesis is theory or not he can simply perform experiments and get confirmed by the results of the experiments.

As a hypothesis can be defined as a rational explanation of a single event or phenomenon based upon what is observed during a particular experiment, but which has not yet been proved. Most of the hypotheses can be supported or refuted by experimentation or continued observation.

Whereas a scientific theory is more like a scientific law which is in mutual agreement with the the given hypothesis. One can perform experiments and compare the results with the theory and get confirmed.
