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?
Certain unusual configurations of data can serve as the basis for precise weather forecasts, even though the exact causal mechanisms are not understood.
Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts.
Mathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.
Modern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time.
Meteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct.
理解题意：但这是一种毫无根据的吹嘘，不需要任何评估，因为任何不充分的天气预报显然都会归咎于模型的缺陷。
A项：某些不寻常的数据结构可以作为精确天气预报的基础，尽管确切的因果机制尚不清楚。
B项：在相关数学模型的准确性方面最显著的提高是伴随着天气预报精度的明显提高。
