But OA is not C. How did you eliminate A?

Thank you

But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model.

Paraphrase : There is no way to measure the accuracy of 'M' model for weather predictions.

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?

Meaning - methodology exists to measure the accuracy.

(A) Certain unusual configurations of data can serve as the basis for precise weather forecasts even though the exact causal mechanisms are not understood. -- may/may not be true.Methodology might be a fluke too.Hence,POE.

(B) Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts. -- accompanied by clear gains --measurement available. Hold.

(C) Mathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.-- accuracy measurement not touched. POE.

(D) Modern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time. -- measurement methodology has not been discussed. POE.

(E) Meteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct. -- weakening choice. POE.

How to eliminate A and D? Experts Please comment.
