Question 1

The sudden dip of the graph shows the significance of 9/11 to the United States. After 2001, it became much harder to have oversea products because security was very strict and the US was afraid of terrorist attacks so oversea arrivals went down right after 9/11 but went continued to rise after that event. Statistics can help explain the significance of historical events because if we find the statistics on a graph for a certain year, we can figure out and research a specific event that occured in that country that made their statistics rise. A specific example is for children per woman because many African countries were at the top since the men would migrate to different woman and have sexual relations with them, so many children were born.
