Answer to Question 1

Answer: A

Answer to Question 2

Answer: During the mature stage of an air mass thunderstorm, as the falling rain or hail drags air toward the surface downdrafts form in the areas of most intense precipitation. As more and more of the cloud yields heavy precipitation, downdrafts occupy an increasing portion of the cloud base. When they occupy the entire base, the supply of additional water vapor is cut off and the storm begins to dissipate.
