Question

class e general knowledge question #13 / 50
when it rains, the roads are most slippery
select a letter to choose your answer.
a. after several hours of light rain.
b. just after the rain stops and the road is drying off.
c. just after the rain begins, because oil dropped from vehicles has not yet been washed away.

Explanation:

When it starts raining, the oil and other substances on the road that have accumulated from vehicles are mixed with the rainwater. At the beginning of the rain, these substances have not been washed away effectively. This mixture creates a slippery layer on the road surface. As the rain continues (options A and B), more of these substances are washed away, reducing the slipperiness compared to the start of the rain.

Answer:

C. Just after the rain begins, because oil dropped from vehicles has not yet been washed away.
