Read the passage carefully and choose the correct answer.
Hurricanes are violent storms that cause millions of dollars in property damage and take many lives. They can be extremely dangerous, and too often people underestimate their fury.
Hurricanes normally originate as a small area of thunderstorms over the Atlantic Ocean west of the Cape Verde Island during August or September. For several days, the area of the storm increases and the air pressure falls slowly. A center of low pressure forms, and winds begin to WHIRL around it. It is blown westward, increasing in size and strength.
Hurricanes hunters then fly out the storm in order to determine its size and intensity and to trace its direction. They drop radiosondes, or instrument for recording temperature, air pressure, and humidity, into the storm. They also look at the size of waves on the ocean, the clouds, and the eye of the storm. The eye is a region of relative calm and clear skies in the center of the hurricane. People often lose their lives by leaving shelter when the eye has arrived, only to be caught in tremendous winds again when the eye has passed.
