After reading this passage from a government textbook, answer the question that follows it. (1)    Public opinion polling is a relatively new science. It was first developed by a young man named George Gallup, who initially did some polling for his mother-in-law, a long-shot candidate for secretary of state in Iowa in 1932. With the Democratic landslide of that year, she won a stunning victory, thereby further stimulating Gallupʼs interest in politics. From that little acorn the mighty oak of public opinion polling has grown. The firm that Gallup founded spread throughout the democratic world, and in some languages Gallup is actually the word used for an opinion poll.(2)    It would be prohibitively expensive and time-consuming to ask every citizen his or her opinion on a whole range of issues. Instead, polls rely on a sample of the population—a relatively small proportion of people who are chosen to represent the whole. Herbert Asher draws an analogy to a blood test to illustrate the principle of sampling. Your doctor does not need to drain a gallon of blood from you to determine whether you have a disease. Rather, a small sample of blood will reveal its properties.(3)    In public opinion polling, a sample of about 1,000 to 1,500 people can accurately represent the “universe” of potential voters. The key to the accuracy of opinion polls is the technique of random sampling, which operates on the principle that everyone should have an equal probability of being selected as part of the sample. Your chance of being asked to be in the poll should therefore be as good as that of anyone else—rich or poor, black or white, young or old, male or female. If the sample is randomly drawn, about 13 percent of those interviewed will be African American, slightly over 50 percent female, and so forth, matching the population as a whole.(4)    Computer and telephone technology has made surveying less expensive and more commonplace. In the early days of polling, pollsters needed a national network of interviewers to traipse door-to-door in their localities with a clipboard of questions. Now most polling is done on the telephone.—Edwards et al., Government in America: People, Politics, and Policy, pp. 176–177 The topic sentence of paragraph 1 is
