Hypothetical is best defined as being ___________.
Correct Answer: C
Rationale: Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.
