Answer: Hypothesis
Theory
Fact /Law
Explanation:
A hypothesis is the foundation of establishing a fact in the sciences or research based fields. A hypothesis is based on an observation. This can be from viewing the relationship between two objects or variables.
When the hypothesis is put to a test, and the results observed under suitable conditions prove the hypothesis to be correct, it becomes a theory.
For a theory to become a fact, several other experiments have to be carried out to rule out other reasons that may yield the same result.
