Scientist: A greenhouse gas, for example, carbon dioxide, forms a transparent layer that traps solar heat beneath it in the earth’s atmosphere. Atmospheric levels of carbon dioxide are currently increasing, causing the climate to warm—an effect that is predicted by at least one computer model of the greenhouse effect. But the warming that has occurred is a great deal less than what would be expected based on the model. Therefore,
Which of the following most logically completes the scientist’s argument?
better measurements of atmospheric levels of carbon dioxide are needed
the definition of “greenhouse gas” should probably be reconsidered
there are factors besides the increase in greenhouse-gas emissions contributing to the warming of the climate
the computer model of the greenhouse effect must be incorrect in some respect
the likely consequences of any warming of the climate are unlikely to be much less damaging than predicted
“这个正确选项真是直白到有点让人不敢选 ”
AB 本质不对。 C是加强。E矛盾。蒙了个D。从来没见过这么赤裸裸的正确答案。
A. It is reasonable to infer from the given information that some aspect of the computer model is incorrect in some way. One way that it might be incorrect is that the measurements of atmospheric levels of carbon dioxide used are inaccurate. Nevertheless, there is not sufficient information to infer that this is the specific flaw in the model.
本题的意思是：实际的结果和模型预测的结果有一定差距，
所以认为：不是气候的问题，就是模型出错
对应D选项，电脑模型对温室效应的模拟是有一定错误的
注意E 的双重否定表示肯定 差点选错了
不是气候有问题 就是模型有问题 must结果不敢选了 CE都是反的
电脑模型可能不正确
实际值与模型预测值不准，说明模型有问题。这个正确选项真是直白到有点让人不敢选

没读懂句子结构导致选错
But the warming that has occurred is a great deal less than what would be expected based on the model.
a great deal 大量的，less than。。比。。少；就是the warming比model出来的少很多。。那肯定是model有问题啊
a 不对应为后面说的是model，不是实际测量
A/B/C are talking about the same thing.
If the model were correct, its predictions would be confirmed by the data regarding warming. However, this has not occurred. It is therefore reasonable to infer that, in some way, the computer model is incorrect.
