The proposition that higher average temperatures would result in less precipitation nationwide is true.

• A. True
• B. False
• C. Not enough information
• D. It depends on context

Answer: (B)

Warmer temperatures don’t automatically mean less precipitation nationwide. As air warms, its capacity to hold water vapor increases, so the atmosphere can carry more moisture that can be released as rain when conditions favor condensation. This tends to intensify the global hydrological cycle, leading to more extreme rainfall events in many places. At the same time, shifts in atmospheric circulation can cause some regions to dry out. Because precipitation response to warming is not uniform and depends on location and weather patterns, the idea of a universal nationwide decrease isn’t supported.
