A comparison of Native American societies in North American reveals that
a. culture and language were the same everywhere
b. distinct cultures arose from difference in local climate and terrain
c. all were nomadic with little knowledge of agriculture
d. local environments ahd little impact on cultural developments
C is clearly out. "Never" and "all" and other words like those indicate something that can't be proven.
Same with "everywhere."
So you're down to B and D. What do you think?
i think B sounds better
Right -- think about Hopi, Navajo, Arapaho, Comanche, Iriquois, etc.
Often, in a multiple-choice exercise, if the correct choice does not come to mind quickly, try the "elimination" method.
