Final answer:
Delayed reciprocity is true and refers to the exchange of gifts where the return is expected at an unspecified future time, building trust and social bonds within communities.
Step-by-step explanation:
The statement Delayed reciprocity is where the return gift happens but not for an undetermined amount of time is true. This concept is often discussed in the context of social and cultural anthropology. Delayed reciprocity involves a situation where an individual gives a gift without expecting an immediate return, but does anticipate that the favor will eventually be reciprocated, often at an unspecified future date. This type of exchange reinforces social bonds and establishes trust within communities.
