9. 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 prediction. 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. (B)
(E) Aristotle’s cosmological theory described a large class of observations in terms of only four elements.
请教：原文里的条件推理怎么写？
我是这样写的：satisfies two requirements --> good theory；即：describe.... AND make definite ... --> good theory
就这样，我就发现选项几个都不对。
请NN指教，不胜感激。
satisfies two requirements --> good theory
所以A：预测是好的理论的必须，正确。
C：题目说亚里士多德的理论满足一点：accurately describe a large class of observations in terms of a model that is simple enough to contain only a few elements。C说Four elements can be the basis of a scientific model that is simple enough to meet the simplicity criterion of a good theory.正确。
D：符合model that is simple enough to contain only a few elements
E：符合accurately describe a large class of observations in terms of a model that is simple enough to contain only a few elements
“must also be true EXCEPT” this include two type of answer choise. One that is false and One that is not false and right which mean it is has nothing to do with this argument,
