Final answer:
Having the ability to complete a task at a lower opportunity cost means you have a comparative advantage, not an absolute advantage.
Step-by-step explanation:
If you can complete a task at a lower opportunity cost than anyone else, this means you have a comparative advantage in that task. Opportunity cost is the cost of the next best alternative that is given up when making a decision to produce a particular good or service. A person or an economy that can produce a good at a lower opportunity cost than others will gain from specializing in producing that good and then trading for goods produced by others. In contrast, having an absolute advantage means being able to produce more of a good using the same amount of resources as others, or the same amount with fewer inputs.
