Which agency predicts temperature changes and conditions?

• A. Weather Service
• B. Temperature Increase
• C. Distance of the Sun
• D. Effective Expression

Answer: (A)

What’s being tested is understanding who actually performs weather forecasting. A weather service is the agency that collects data from weather stations, satellites, radar, and other sources, then uses computer models to predict future conditions such as temperature changes and other atmospheric variables. That direct forecasting role is why this choice is the best fit. The other options aren’t about organizations that forecast weather: temperature increase describes a trend, distance of the Sun is a scientific fact about astronomy, and effective expression has no relation to weather predictions.
