Which of the following is an assumption on which the argument above depends? (A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census. (B) All Americans may reasonably be classified as either poor or rich. (C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted. (D) The number of homeless Americans is approximately equal to the number of rich Americans. (E) The primary purpose of the census is to analyze the economic status of the American population.
