Final answer:
Jordan's production possibilities frontier is based on 12 months of work since she requires 3 months to write each novel, allowing her to potentially write up to 4 novels in a year.
Step-by-step explanation:
If Jordan must work 3 months to write each novel, her production possibilities frontier (PPF) would be based on the total number of months she has available to work. The PPF graphically represents the maximum number of novels that Jordan can produce given her limited resources, which in this case is her time.
If we assume Jordan can work the entire year on writing novels, she would have 12 months in a year. Therefore, her PPF would be based on these 12 months of work, meaning she could potentially write up to 4 novels in a year (12 months / 3 months per novel).
