Binford's Ethnoarchaeological Work with the Nunamiut Eskimo of Alaska Demonstrated

Binford's ethnoarchaeological work with the Nunamiut Eskimo of Alaska demonstrated:

A) that it was safe for archaeologists to assume that a difference in artifacts reflects a difference in culture.
B) that different artifact assemblages could result from different activities conducted by the same culture.
C) the likelihood that different Mousterian tool assemblages were a result of different Neandertal tribes.
D) that the same people leave the same kinds of tools at different locations across the landscape.
