a. understanding the attitudes of indians living between the appalachians and the mississippi.
b. understanding the role of catholic priests in california and the spanish southwest.
c. explaining the relationship between german and scots-irish settlers in the backcountry.
d. explaining the attitudes and preferences of the scots-irish.

i think the answer is c, rivers.

explanation:
