Final answer:
True. The existence of turns suggests an economy and value system because turns indicate the allocation and exchange of resources, requiring a system to determine how these are distributed, particularly when dealing with scarcity.
Step-by-step explanation:
True. The existence of turns indeed suggests the presence of an economy and value system. When we talk about turns in this context, it can refer to the allocation of resources or services taking place in a society. An economy exists where resources, goods, and services are produced and exchanged, and this inherently requires a system of value to determine how these goods and services are distributed. Moreover, the concept of scarcity, which is the limited nature of society's resources, further necessitates a value system, as it requires decisions to be made about allocation. For instance, if the residents of a town like Smithfield enjoy hams and each ham requires 10 people to produce it over a month, and the town has 100 people, then, assuming all 100 people are involved in production, they can produce a maximum of 10 hams in a month considering it takes 10 people to produce one ham.
