What can be inferred about the weatherman's explanation?

The inference that the weatherman couldn't explain the unusual weather suggests a lack of clarity or certainty in his communication. When individuals face atypical weather patterns, they may struggle to provide a definitive explanation due to the complexity of meteorological factors involved. This option indicates that despite possibly having access to data, the weatherman did not convey concrete answers or insights about the unusual conditions. A detailed explanation typically requires confidence in the forecast or a comprehensive understanding of the causes behind the weather, which appears to be lacking in this case.

The other options suggest outcomes that imply varying levels of competence and insight, such as offering a detailed analysis, making accurate predictions, or categorizing the weather as normal—all of which would contrast with the notion that he was unable to explain the unusual situation.
