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.?à 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?
