Passage VI
Air at its dew point temperature (or dew point) is saturated with water vapor. Air temperature usually decreases with increasing altitude. When air cools to its dew point, the water vapor in the air can begin to condense and form clouds.
Air temperatures and dew points were measured every 600 m from the surface (0 m) to an altitude of 3,000 m at 4 cities (A-D). Data, including the altitude of the cloud base over each city, were taken at 2 P. M. on every summer day that clouds were present. Figures 1-4 show the average air temperatures, the average dew points, and the average cloud-base altitudes at each city.
31. A pilot flying a plane at 1,200 m altitude notices that there are cloud layers both above and below her, but none at her current altitude. Which of the following statements about the weather conditions at or near her altitude is supported by the information provided?
Your Answer is
Correct Answer is C
Explanation
There is no cloud at an altitude of 1200 m, which means that the temperature here is higher than the dew point
