ff 97 -why --?

97. 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) For 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.

Why the Key is B? In my opinion, E is not fully supported by the passage.

B　原文对两个条件没有分主次关系，也就是不存在ｍａｊｏｒ　ｃｏｎｃｅｒｎ

E　是在复述什么是ｍｏｄｅｌ，要用少的变量来描述大而复杂的现象。

B: it is discussing the concepts about the first requirement

E:  A's theory do meet the first requirement.
