Final answer:
Skids are likely to occur on roads where the snow has become packed. A road that has just been paved will have a smooth, fresh surface with good traction, reducing the likelihood of skids.
Step-by-step explanation:
Skids are likely to occur on roads where the snow has become packed (Option A). When snow becomes packed, it forms a layer of ice on the road surface, reducing the friction between the tires and the road. This lack of friction makes it difficult for the tires to grip the slippery surface, leading to skidding.
On the other hand, a road that has just been paved (Option B) will have a smooth, fresh surface with good traction. This surface provides better grip for the tires, reducing the likelihood of skids.
