StrengthenDiff: Hard

Logic Breakdown

Passage Summary: A TV meteorologist claims their station is better than the popular competition because they are more accurate specifically when they predict it will rain.

Conclusion: The weather forecasts provided by this station are more reliable and useful than those of the area's most popular station.

Reasoning: The station is usually correct when it predicts rain, whereas its competitors are not as accurate in their rain predictions.

Analysis: The meteorologist is bragging about their 'hit rate' for rain, but they are ignoring two major things: how often they miss rain that actually happens, and how accurate they are when they predict no rain. To strengthen this claim of superior reliability, we need to know that the competitors aren't actually better in those other categories. Look for an answer that suggests the competitors are frequently wrong in ways this station is not, or that rain prediction is the only metric that truly matters for reliability.
