I guess the correct answer is has the comparative advantage in cooking.
Roommates Sarah and Zoe are hosting a Halloween party and have to make food for their guests and costumes for themselves. To finish both tasks as quickly as possible, Sarah and Zoe know that each of them should focus on just one task, but they don't know who should do what. To decide which roommate should do the cooking, Sarah and Zoe should determine which roommate has the comparative advantage in cooking.
