When studying a culture today, anthropologists try to find cultures that have never been contacted by another culture. only study cultures with no access to television. must consider power differentials and how they affect cultures. must focus on one site at one point in time. will not take photos of their informants due to privacy laws.

Must consider power differentials and how they affect cultures

Explanation:

Of all the statements included in the question, the one above is the most correct. Anthropologists (sociologists and psychologists too) use power as a powerful variable to research and explain the culture of a particular society. This is because power can define from who can access to culture, to who is cultured and who is not, to even what is considered culture and what is not.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.

the answer to your question is,

d. when a child was born.
