Final answer:
Multiple modes of exchange, including traditional, command, or market-oriented economies, can and do coexist within societies due to the variety of ways people exchange goods and services.
Step-by-step explanation:
It is not accurate to say that only one mode of exchange can exist in a society at any one time. Societies often employ a mix of traditional, command, or market-oriented economies. This complexity reflects the diverse ways in which goods and services are exchanged, from bartering and gift-giving to the use of symbolic money. As such, multiple modes of exchange, including reciprocity and market exchange, often coexist, and societies adapt these methods according to their needs and circumstances. In modern capitalist societies, forms of exchange like generalized reciprocity among family, balanced reciprocity among acquaintances, and market exchange principally among strangers can all be found.
