A) Gets weaker B) gets stronger C) move faster D) stays longer
14. Which the following best compares the wind speed within the eye and at the eyewall of a typhoon?
A) the wind speed at the eyewall is much lesser than the wind speed at the eye.
B) the wind speed at the eyewall is much greater than the wind speed at the eye.
