Question

Alec has graduated from college and is moving to a large city to start a new job. Once he arrives, he plans to buy his first new car. Because he has asthma and is concerned about the effects of air pollution, he wants to consider environmental factors in his choice of vehicle and in his driving habits. He also wants to avoid asthma-related health problems associated with air pollution. If Alec wants to reduce the chance that he will contribute to a major smog occurrence, he should limit his driving time/distance in all of the following areas or conditions EXCEPT:

Answer 1

Answer:

Cold weather

Explanation:

The reason that Alec should limit his driving time/distance in all of the following areas or conditions except for cold weather is because of a concept called temperature inversion. Temperature inversion means that in winter season there is a warm layer of air trapped between two cold layers of air. This happens in winter as the air at altitude is always cold but now the surface temperature or air is also cold. Hence, the warm air above the surface and at lower altitude traps air pollutants contributing to smog occurrence. This is a natural phenomenon and therefore, Alec cannot reduce the chance that he will contribute to a major smog occurrence during cold weather by limiting his driving.
