Throughout the Popoya Islands community pressure is exerted on people who win the national lottery to share their good fortune with their neighbors. When people living in rural areas win the lottery they invariably throw elaborate neighborhood feasts, often wiping out all of their lottery winnings. However, in the cities, lottery winners frequently use their winnings for their own personal investment rather than sharing their good fortune with their neighbors. Which one of the following, if true, contributes most to an explanation of the difference between the behavior of lottery winners in rural areas and those in cities?
A: Lottery winners in rural areas are notified of winning by public posting of lists of winners, but notification in the city is by private mail.
B: Families in rural areas in the Popoyas many contain twelve or fourteen people, but city families average six or seven.
C: Popoyan city dwellers tend to buy several lottery tickets at a time, but they buy tickets less frequently than do rural dwellers.
D: Twice as many lottery tickets are sold in rural areas as are sold in the city.
