Answer 1

The answer to the question stated above is letter D. more;higher.

Clouds act in much the same way as high humidity in Earth's atmosphere. The presence of clouds means moist, humid, atmospheric conditions. This promotes greater (more) heat retention, and higher nighttime temperatures, than on a clear, dry night.

Answer 2

The correct answer is (D) more; higher

The cloudy weather has more heat retention quality and at night time the temperature is higher because the clouds does not allows the heat to go out of the atmosphere. The clear sky allows the heat to fall on the earth without hindrance and the same heat escapes at night making the temperature low. But due to clouds the the phenomenon completely opposite, the clouds does not allows the heat to escape at night and does not allows more heat to fall on the earth at daytime.
