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.

There are numerous tactics to syntax that range of their central assumptions and dreams. The sector of syntax includes some of the various topics that a syntactic principle is frequently designed to deal with. The relation among the subjects is treated in another way in specific theories, and a number of them may not be considered to be distinct but instead to be derived from one another.
