9. During which of the following time periods was there a decrease in the
American Indian population?
A. 1910 to 1920
B. 1920 to 1930
C. 1930 to 1940
D. 1960 to 1970
E. 1970 to 1980
The correct answer is A. Because the slope of the line goes down from 1910 to
1920, there must have been a decrease. If you read the actual numbers, you notice
a decrease from 300,000 to 250,000 between those years.
