For a monopsonist, the marginal factor cost is always

greater than the wage rate

A country that has a lower opportunity cost of producing a good

has a comparative advantage

Consider a consumer who spends all income on only two goods: bread and wine. An extra loaf of bread would give the consumer 10 extra utils, while an extra bottle of wine would give the consumer 60 extra utils. Bread costs 50 cents per loaf, and wine costs $6 per bottle.
