Suppose saturated polar air has an air temperature and dew point of -10°C,and unsaturated desert air has an air temperature of 35°C and a dew point of 10°C.The desert air contains ____ water vapor and has a ____ relative humidity than the polar air.
A) more,lower
B) more,higher
C) less,lower
D) less,higher

The desert air has a higher air temperature and a higher dew point, indicating that it contains more water vapor. The polar air, on the other hand, has a lower air temperature and dew point, indicating that it is already near saturation and contains less water vapor. Since relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount it can hold at that temperature, the desert air will have a lower relative humidity than the polar air. Therefore, option A is correct.
