???????????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 怎么推出来的???????/ 看feifei 135 的解释经常觉得好像有不理解的地方,比如这个,逆反是怎么出来的??? |
