feifei 135 第97题

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, 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
(E) Aristotle’s cosmological theory described a large class of observations in terms of only four elements.

对于本题，我看了相关的讨论，不是很清晰。我始终认为 A选项不对。举个例子。
北大的学生必须满足两个条件： A高考考上800分；B报了北大。（同时，本人认为这两个条件仅是必要条件，而非充分）

那么按照 A答案的逻辑：就是高分（800分是高分的子集）的同学肯定是北大中任何任何一个学院的学生。
这显然不对，高分的学生也可能是清华的学生！假如A 改为 could be made , 才可为正确。
