这道题争论的是天气预报专家设计的模型是否只是理论可行,根本无法用,这个人说for any inadequate weather forecast would obviously be blamed on imperfections in the model, 即任何不准确的天气预报都会背归咎于模型设计的不完善,这里就说明无法设计出来完美的模型. B在这里反驳说Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts,意思是相关的模型的 准确性大部分是和天气预报的精确并存的. 即如果模型不准确,天气预报也不可能准确
