(1)For many years the University of Chicago's National Opinion Research Center has asked respondents whether they think the federal government is spending too much, too little, or about the right amount of money on "assistance for the poor." (2)Answering the question posed this way, about two-thirds of all respondents seem to believe that the government is spending too little. (3)However, the same survey also asks whether the government spends too much, too little, or about the right amount for "welfare." (4)When the word "welfare" is substituted for "assistance for the poor," about half of all respondents indicate that too much is being spent by the government. The sentence that best expresses the implied main idea is: a. Chicago's National Opinion Research Center is a leader in conducting public opinion research. b. Most Americans believe that the government spends too much money on welfare. c. In opinion polls, how a question is phrased can affect the answers people give. d. Most people want the United States government to give more assistance to the poor
