Verified step by step guidance

1. Understand the definition of a market interaction: it involves an exchange where goods or services are traded, usually with payment or a price mechanism involved.
2. Identify scenarios where there is a clear transaction involving money or a price, such as buying a textbook online, purchasing groceries, or selling vegetables at a farmers' market. These are all market interactions.
3. Recognize that an interaction outside of a market occurs when goods or services are exchanged without a monetary transaction or formal price mechanism.
4. Analyze the scenario where a neighbor helps another neighbor move furniture without any payment. Since there is no exchange of money or price, this is an example of a non-market interaction.
5. Conclude that the correct example of a person interacting outside of a market is the neighbor helping another neighbor move furniture without any payment.
