Answer:
Ethnographic fieldwork.
Step-by-step explanation:
Ethnographic fieldwork is a methodology that anthropologists use to collect information about a community by living and interacting with it for some time. By doing this, they collect data that helps them to know the unfamiliar culture and how that community works. In other words, ethnography tries to understand the culture of a community from the community's point of view, and also from the eye of a professional, who interprets the different events that take place in that society.
