Questions 12-13 are based on the following.
Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities (sufficient, 有这个就行), they could forecast the weather with real precision. But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model.
数学模型====>精确天气预告
~精确天气预告====>~数学模型
12. Which of the following, if true, could best be used as a basis for arguing against the author’s position that the meteorologists’ claim cannot be evaluated?
(A) Certain unusual configurations of data can serve as the basis for precise weather forecasts even though the exact causal mechanisms are not understood.
(B) Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts.
(C) Mathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.
(D) Modern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time.
(E) Meteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct.
13. Which of the following, if true, would cast the most serious doubt on the meteorologists’ boast, aside from the doubt expressed in the passage above?
(A) The amount of energy that the Earth receives from the Sun is monitored closely and is known not to be constant.
(B) Volcanic eruptions, the combustion of fossil fuels, and several other processes that also cannot be quantified with any accuracy are known to have a significant and continuing impact on the constitution of the atmosphere.
(C) As current models of the atmosphere are improved, even small increments in complexity will mean large increases in the number of computers required for the representation of the models.
(D) Frequent and accurate data about the atmosphere collected at a large number of points both on and above the ground are a prerequisite for the construction of a good model of the atmosphere.
(E) With existing models of the atmosphere, large scale weather patterns can be predicted with greater accuracy than can relatively local weather patterns.
两个题目答案都是B, 第二个好说, 容易理解, 这个第一个就是不能理解. 请求指教. 不晓得里面的关系是怎么弄的.看不出这个B选项是怎么反对作者观点的.
谢谢先!!!!
这一题不是考，从if A ，B不能推出if B， A；这一题是考，immune to evaluation。选项B证明can be evaluated（not immune to evaluation)。

气象学加的理论是：只有有精确的模型，天气问题就可以搞定。
反驳：天气问题一搞不好，你就可以怪模型不好。隐含认为还有其他原因导致天气预测不准。
支持气象：每次数学模型方面的重大进步都伴随着天气预测更加准。部分支持，说明模型的确有点用。

哎哟, 多谢楼上的GG们, 真是的, 偶就是想不通这个....
嗯, 就是有罗嗦了一遍嘛
你说"不行" 偶就说"就是行, 每次都行"!!! 这不是无赖理论嘛

Almost everyone has reached this conclusion. But more often than not we still cherish unrealistic fancies that the conclusion were not true.
同意。实际也有weaken原因for后面的意思。
Almost everyone has reached this conclusion. But more often than not we still cherish unrealistic fancies that the conclusion were not true.
This sentence is very very gmatted.
容小妹仰视一下!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Almost everyone has reached this conclusion. But more often than not we still cherish unrealistic fancies that the conclusion were not true.
能写出这句话的确很NN．
看看Passage17
In localities where clerical workers were few in number, were scattered in several workplaces, and expressed no interest in being organized, unions more often than not ignored them in the pre-1975 period
more often than not就是十分原意的意思．欢迎指正
tianwan、jnlvo、weiyu、pumpkin我都很佩服你们。
你们做事情都一丝不苟，细心细致！
而weiyu和tianwan在考虑逻辑问题的时候还能准确的分析问题，并将其表达出来。我实在佩服！
我做GMAT题目，大多就是凭感觉。。。所以始终提不到一个高度上，哎，也不知道如何是好
我觉得GMAT纠其根本在考逻辑思维

dreadpower客气，你的假设判定方法是将逻辑理论和实际结合的经典著作
dreadpower的这个得意之作在哪？渴求ing
