In 1980, 18% of American families lived under the poverty line. In 1990, only 12% of families lived under the
poverty line. But that doesn’t mean fewer families were living in poverty. Indeed, the statistics hide the fact that
more families were actually living in destitution. The difference in percentages appears because the poverty line
was redefined and the income level was reduced. Thus, many families were above the poverty line even though
they did not earn any more income.
Which of the following statements, if true, would most strengthen this argument?

lasted one hour less. What is the distance (in km) between A and B?
