标题: 狒狒97
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.
题意大概：
一个理论，必须要元素少，并且必须能够预测未来，就是好理论
Aristotle’s cosmological theory，满足了前面的条件，但是没有满足后面的条件，所以不是好理论
题目问的是以下选项肯定成立，除了哪个之外？答案为B
B是肯定不对，应该是答案，这点毫无疑问
但是A也不一定成立：对未来进行预测的不一定都是由good scientific theory提出的，可能某个理论不能满足元素少的条件，但是也进行也预测，不是好理论，就是一个反例。

真是有些糊涂了，我认为a肯定是错的
b也好不到哪里去
再来个兄弟看看吧

我们可以把A选项A) Prediction about the results of future observations must be made by any good scientific theory改成主动语态，就是any good scientific theory must make Prediction about the results of future observations.这样就会发现句子是在强调“any”，任何，还是再说good scientific theory的必要条件。

请指教！

Prediction about the results of future 是scientific theory 的必要条件
而原文里对scientific theory
又作出了很详细的定义，也完全符合上面的这个必要条件
所以a就是对的咯
上次看的时候不知道怎么回事状态不好，呵呵，都没看出个答案来

那B为什么对呀？是不是反了？actually it's a major concern?

怎么可能是b阿。。。must be true, except。。

这种题就是说求一定错误的咯？

feifei的解释是b没提到 b还是提到的 b作为答案ok

但a同样也不对啊。。。 a一看就是逆命题么逆命题不是一定错的咩？

按常理来说，prediction也可以made by bad theory阿。。。

B无关选项也可以作为答案的,
但是A 太tricky 了!
