Answer:
Work in adverse conditions
Step-by-step explanation:
Wages that employees working in the petroleum industry in Alaska receive may be higher because they would be working in adverse conditions because this is a territory with a really hard climate in which to live as it is really cold with snow almost all the year which makes it a place where people usually don't want to live in and offering higher salaries is also a way for companies to attract and maintain their workers in this place.
