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.

<span>Hypotheses generally (although not always) follow an "If-then" format. This eliminates the first and fourth choices. Of the other two, the second choice (regarding cold weather and tires) can still be tested and verified. The third statement, regarding the end of WWII, is a statement that can't be verified to any appreciable extent and can only go on eyewitness testimony and historical testimony, so it fails the scientific method test.</span>
