PrepTest 66, Section 2, Question 22
The airport's runways are too close to each other to allow simultaneous use of adjacent runways when visibility is poor, so the airport allows only 30 planes an hour to land in poor weather; in good weather 60 planes an hour are allowed to land. Because airline schedules assume good weather, bad weather creates serious delays.

Which one of the following is most strongly supported by the information above?
In poor weather, only half as many planes are allowed to land each hour on any one runway at the airport as are allowed to land on it in good weather.
When the weather at the airport is good it is likely that there are planes landing on two adjacent runways at any given time.
If any two of the airport's runways are used simultaneously, serious delays result.
Airlines using the airport base their schedules on the assumption that more than 30 planes an hour will be allowed to land at the airport.
In good weather, there are few if any seriously delayed flights at the airport.
