In 1720, 90% of the population died during an outbreak of smallpox, leaving only a small number of individuals who were able to grow crops. Consider a hypothetical version of the aftermath of the smallpox outbreak, where there are only two individuals who are able to grow and harvest crops: Freya and Calum.

Freya lives in the north of the island, where potatoes grow better than oats.

Calum lives in the south of the island, where potatoes grow almost as well as oats.

Assume that there is currently no trade possible with other islands.

Below is a table that shows a fictional version of the production possibilities of both Freya and Calum for the coming year. Assume that the opportunity costs are constant (i.e. the feasible frontiers for both individuals are linear):

	If 100% of time is spent on the production of one crop	Self sufficiency
	Potatoes (kg)	Oats (kg)	Potatoes (kg)	Oats (kg)
Freya	1000	400	300	250
Calum	800	1000	350	400

a.) Does either individual have an absolute advantage in producing potatoes? What about oats? Explain your answer.
