Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, 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.
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?
-
ACertain unusual configurations of data can serve as the basis for precise weather forecast, even though the exact causal mechanisms are not understood.
分析该选项
-
BMost significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts.
分析该选项
-
CMathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.
分析该选项
-
DModern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time.
分析该选项
-
EMeteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct.
