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 preictions 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 fist requirement,but it did mot make any definite predictions.so it is not a good theory.

if all the statements in the passage are true ,eash 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) Elements that is simple enough to meet the simplicity criterion of a good theory can be the basis of a scientific model

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 .
