Answer to Problem 1CQQ

Option ‘b’ is the correct answer.

Explanation of Solution

Option (b)

In the United States over the past century, average income measured by real GDP per person has grown by about 2 percent per year and this rate of growth implies that average income doubles every 35 years and hence, because of this growth, most of the Americans enjoy much greater economic prosperity than before. Thus, option ‘b’ is correct.

Option (a)

The rate of growth of 2 percent in the U.S. economy over the past century implies that average income doubles every 35 years and not in every 14 years. So option ‘a’ is incorrect.

Option (c)

Over the past century, in the U.S., real GDP per person has grown by 2 percent which means it doubles every 35 years. So option ‘c’ is incorrect.

Option (d)

Over the past century, in the U.S., real GDP per person has grown by 2 percent and not by 5 percent. Hence option ‘d’ is incorrect.
