[求助]feifei-97：有关充要条件的疑问。非常困惑……

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.

After analysis , we can find that the reasoning in this argument is that:

1>      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  2> it must make definite predictions about the results of future observations.ßà A scientific theory is a good theory

So , we can find all of choices except B satisfied with the original meaning.

B is not mentioned in this argument , so we can conclude whether B is also true.

So B is the best answer.

根据原题第一句话：如果科学理论是个好理论，那它满足两个条件：其中第二条：it must make definite predictions about the results of future observations。对选项A有疑问：1.题目说是definite predictions，A是 predictions，这能等同吗？2.也是最疑惑的，满足两个要求是好理论，也就是说好理论能够有明确的推断。A中说推断来自好理论？这个推理过程有问题吧。Prediction about the results of future observations must be made by any good scientific theory 这句话该怎么理解？

怎么没人帮忙？up

先谢ls。definite不是问题的关键。 a good theory -〉it must make definite predictions about the results of future observations。可是A中说什么？Prediction about the results of future observations must be made by any good scientific theory ，这个推理好像是错误的吧？
