A scientific theory is a good theory if it satisfies two requirements. It must accurately describe a large class of observations in terms of a model that is simple enough to contain only a few elements, and it must make definite predictions about the results of future observations, For example, Aristotle's cosmological theory, which claimed that everything was made out of four elements---earth, air, fire, and water---satisfied the first requirement, but it did not make any definite predictions. Thus, Aristotle's cosmological theory was not a good theory.
If all the statements in the passage are true, each of the following must also be true EXCEPT:
(A) Prediction about the results of future observations must be made by any good scientific theory.
(B) Observation of physical phenomena was not a major concern in Aristotle's cosmological Theory
(C) Four elements can be the basis of a scientific model that is simple enough to meet the Simplicity criterion of a good theory.
(D) A scientific model that contains many elements is not a good theory
(E) Aristotle's cosmological theory described a large class of observations in terms of only four elements.
