Answer:
B. Exposure.
Explanation:
The act exhibited by the highway crew can easily be explained to be exposure because of his stance from a mountain end and their reaction.
Measurement of exposure is generally defined as some form of
the amount of travel, either by vehicle or on foot. Once the amount of travel
is known for certain activities, or road users, and if we know the number of
crashes that are associated with that activity or population, the associated
risk can be calculated. Also the various ways of measuring the amount of travel are referred to collectively as exposure
data because they measure traveller’s exposure to the risk of death or
injury.
