In summer, humid regions typically have ________ daily temperature ranges and _______ maximum temperatures than drier regions.

The correct answer is: C. Larger, lower.

Humid regions typically have larger daily temperature ranges and lower maximum temperatures than drier regions. This is because water vapor in the air acts as an insulator, trapping heat and preventing it from escaping into space. This makes it more difficult for the temperature to drop at night, and more likely for the temperature to rise during the day.

In drier regions, there is less water vapor in the air, so the temperature is more likely to drop at night and rise during the day. This is why deserts are often very hot during the day and very cold at night.

Here is a more detailed explanation of each option:

• Option A: Smaller, lower. This is not correct because humid regions typically have larger daily temperature ranges than drier regions.
• Option B: Smaller, higher. This is not correct because humid regions typically have lower maximum temperatures than drier regions.
• Option C: Larger, lower. This is the correct answer because humid regions typically have larger daily temperature ranges and lower maximum temperatures than drier regions.
• Option D: Larger, higher. This is not correct because humid regions typically have lower maximum temperatures than drier regions.
