An argument concludes that 'because average temperatures have increased by 2 degrees over the past decade in our city, we must immediately invest in more snow-removal equipment, as warmer winters will lead to more freezing rain and thus icy roads.' Which of the following is the most significant logical leap or unstated assumption in this conclusion?

The correct answer to the question "An argument concludes that 'because average temperatures have increased by 2 degrees over the past decade in our city, we must immediately invest in more snow-removal equipment, as warmer winters will lead to more freezing rain and thus icy roads.' Which of the following is the most significant logical leap or unstated assumption in this conclusion?" is Option C: Freezing rain necessarily requires *more* snow-removal equipment than snow..

The other options — A) The 2-degree temperature increase is significant enough to cause a substantial change in precipitation type., B) The city experiences significant snowfall to begin with., D) The observed temperature trend will continue indefinitely into the future. — are incorrect for this GMAT Exam Prep question. As explained above: The conclusion illogically equates the need for managing freezing rain/ice with *more snow-removal equipment*. Freezing rain often requires de-icing equipment, which is distinct from snow plows.
