To determine the number of people who lived in North and South America during the Paleo-Indian Period, we will consider the estimated population provided by historical and archaeological research.
The estimated population of people living in these regions during the Paleo-Indian Period is 7,100,000.
Now, we need to match this number to one of the given options:
a. 50 million
b. 7-10 million
c. 17 million
d. 70 million
The closest match to 7,100,000 (which is equivalent to 7.1 million) is the option that provides a range encompassing this number:
Option (b), 7-10 million, is the best fit.
Therefore, the correct answer is:
O b. 7-10 million
