In view of such striking achievements, it seemed rather improper for the young American journlist, George Gallup, to claim that large numbers were irrelevant, and that equally accurate or better predictions could be made with a small but carefully selected sample of the population and a small team of skilled interviewers.
In 1936, Gallup convinced thirty-five newspaper editors that his system was much cheaper than the customary mass inquiries and that it could provide surprisingly accurate predictions. The editors finally agreed. On condition that if Gallup's predictions were less accurate than those obtained by the tried method of the Literary Digest, he would have to refund the entire cost of the investigation. Although the Literary Digest broke its own record by obtaining two million replies to its electoral postcards that year, its prediction was wrong by 19%, whereas Gallup's was off by less than 1%.
Suddenly Gallup's name was on everyone's lips. Not only was he the prophet of the moment, but it was generally conceded that he had founded a new and most important scientific method of prediction. He was showered with money and commissions, and the Gallup Poll becomes a common term for public opinion polls.
Gallup usually samples his subjects according to six factors: state, size of community, age, sex, income, and political affiliation. From time to time, other factors may be considered, during time of war, for instance, the national origins of electors may be taken into account.
Only when the composition of the electorate has been accurately determined can the purely arithmetical question -- how many people in each bracket must be interviewed -- be solved. Once this is done, laws of probability take over, and the more people interviewed, the more exact the estimates will be. However, above a certain maximum number of interviews, the accuracy increases by no more than a fractional percentage -- and where errors of up to 2% are permissible, a few thousand questionnaires will accurately reflect the opinions of the total United States electorate.
Gallup's method of sampling the electorate was successful. Before Gallup, political predictions were no more than shots in the dark, and it is as a result of his achievement that today we can make truly scientific forecasts in this difficult field.
How does the author like the common principle held in the pre-election poll？
A．It was successful because it took all sections of the population into consideration.
B．It was successful because the publications sent out numerous questionnaires.
C．It was unsuccessful because it didn't take the composition of the electorate into consideration.
D．It was unsuccessful because it put emphasis on quality instead of quantity.
Since 1947 Canada has had a tax-supported health care system in which every Canadian is covered for the costs of all medically necessary services. Under this plan, each citizen is issued a health card by the government, which is presented when health care is received. Using tax money, the government pays back physicians and hospitals, based on a fee schedule determined by the government, not the market. The keys are that the health services are paid for by the government and all Canadians have equal access to the care they need. Canadians can select any doctor they like. The plan is a "single payer"plan, with the doctors billing the provincial insurance plans directly (the government of each Canadian province pays the medical bills of its citizens). For patients, there are no bills, claim forms, fees, and long waits for compensations from insurance carriers.
The key difference between the Canadian system and that in the United States is that "in Canada health care is considered a social right, while in the United States it is treated more like a commodity".
The usual arguments against such a plan are that it is inefficient and costly. In Canada's case, health care is administered more efficiently, at less cost, and with better results, than the health care system in the United States. The results, as measured by infant mortality and life expectancy, show that Canada is ahead of the United States. Administrative costs are less in Canada (about one-fourth of U. S. administrative expenses for physicians, hospitals, and insurance companies).
The Canadian health care system is not perfect. Canadians have less access than Americans to the latest technological innovations. There may be waits for those not needing immediate surgeries. But despite some small problems, most Canadians like their health care system. A Gallup Poll in 1991 revealed, for example, that 91 percent of Canadians rated their health care system better than that in the United States, compared to only 26 percent of Americans who felt their system was superior to that in Canada.
The Canadian health care system is
A．financially supported by private enterprises.
B．run according to different principles.
C．designed for the convenience of the public.
D．complicated by administration.
The Gallup Poll shows that the number of people__________.
A．who suffer from the worst disease AIDS has fallen
B．who think AIDS threatens the countryside has fallen
C．who worry about AIDS and health problems has fallen
D．who think AIDS is the country's top health killer has fallen

Unlike the private enterprise model, which is the foundation of the U. S. health care system, Canada has a health care system based on different principles:l) Universality: everyone is covered. 2) Portability:people can move from province to province and from job to job, or be un-employed, and they will still be covered. 3) Comprehensiveness: the plan covers all medically necessary treatment. 4) Public administration: the system is publicly run and publicly accountable.
