Answer:
Susan could see clouds through the window of the airplane because the airplane was flying above the clouds.
Explanation:
- The average height at which the clouds are formed is 28,000 to 38,000 feet and the height at which airplanes usually fly when the conditions are normal is 40,000 feet.
- Thus, it can be said that the airplanes usually fly above the clouds and that is the sole reason why one can see clouds from the airplane window.
