Step-by-step explanation:
Comparative Advantage is an economic term which refers to a situation where a country can produce more of a particular Commodity at a lower cost.
An individual or company is said to have comparative advantage in production if they can produce more units at a reduced cost.
Joan is said to have comparative advantage of producing basket because she produces more units(4) of basket that mark(1) at a lower cost (time).
Having a comparative advantage in production of a commodity doesn't mean Joan is more skilled in making baskets.
