During the American westward expansion, a certain city in the eastern U.S. saw about 250 of its citizens depart for the west, but perish before arriving in their destination cities. During the same time period, the city saw about 225 deaths of citizens who stayed in the city. Based on these totals, it can be concluded that it was not much more perilous to be a settler who left the eastern U.S. to settle the western U.S. than it was to be a citizen who remained in the east.

Which of the following tests would most clearly reveal the flaw in the conclusion drawn above?

A) Counting deaths among people who left to settle the west but returned to their cities of origination in addition to those who died during their trips westward
B) Calculating the difference between the number of deaths among westward settlers and the number of deaths among non-settlers, then expressing this number as a percentage of all deaths during the period
C) Differentiating between settlers' deaths by non-settlement-related causes and those caused by accidents, murders, and battles attributable to the settlement process
D) Comparing the death rates per hundred members of each group instead of comparing the numbers of deaths in each group
E) Comparing deaths due to natural causes in the city of origin to unnatural deaths of settlers who originated in those cities
