Most Americans stop working at the age of sixty-five or seventy and retire. Because work is such an important part of life in American culture, retirement can be very difficult for Americans. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire, but leaving one's job, whatever it is, is a difficult change, even for those who look forward to retiring. Retirement can also bring financial problems. Many people depend on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. Each employer also gives a certain percentage to the government. When people retire, they receive this money as income. Sometimes these checks do not provide enough money to live on, because prices are prone to increasing, a process known as "inflation". Senior citizens, those over sixty-five, typically have to have savings in the bank or other retirement plans to make ends meet. In addition, many senior citizens have to change their lifestyles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities(必需品). Of course, many senior citizens are happy with their retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part-time, others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to start new businesses. Many retired citizens also belong to "Golden Age" groups. These organizations plan trips and social events. There are many other opportunities for retirees. Which of the following could be the best title of the passage？ A．Golden Age Groups B．The American Opinion of Work C．The Importance of Work in America D．The Problems of Retirement in America

A．Appreciating. B．Critical. C．Supportive. D．Positive.

Both it and the authors have openly admitted their doubts. They have acknowledged in interviews that the population totals for 2000 and 1990 were reached by different methods and are not directly comparable. The survey itself also cautions readers, in a dauntingly technical appendix, that judgment calls by the researchers may have led to an undercount. When the research director and project director were asked whether the data should be construed to indicate a declining Jewish population, they flatly answered no. In addition, other survey researchers interviewed pointed to other studies with population estimates as high as 6.7 million. Despite all this, the two figures --5.2 million now, 5.5 million then --are listed by side in the survey, leaving the impression that the population has shrunk. The result, predictably, has been a rash of headlines trumpeting the illusionary decline, in turn touching off jeremiads by rabbis and moralists condemning the religious laxity behind it. Whether out of ideology, ego, incompetence or a combination of all three, the respected charity has invented a crisis. United Jewish Communities is the coordinating body for a national network of Jewish philanthropies with combined budgets of $2 billion. Its population surveys carry huge weight in shaping community policy. This is not the first time the survey has set off a false alarm. The last one, conducted by a predecessor organization, found that 52 percent of American Jews who married between 1985 and 1990 did so outside the faith. That number was a fabrication produced by including marriages in which neither party was Jewish by anyone's definition, including the researchers. Its publication created a huge stir, inspiring anguished sermons, books and conferences. It put liberals on the defensive, emboldened conservatives who reject full integration into society and alienated ordinary folks by the increasingly xenophobic tone of Jewish communal culture. The new survey, to its credit, retracts that figure and offers the latest survey has spawned a panic created by the last one. So why did the organization flawed figures once again？ Some scholars who have studied the. survey believe the motivation then came partly out of a desire to shock straying Jews into greater observance. It' s too early to tell if that' s the case this time around. What is clear is the researchers did their job with little regard to how their data could be misconstrued. They used statistical models and question formats that, while internally sound, made the new survey incompatible with the previous one. For example, this time the researchers divided the population of 5.2 million into two groups--"highly involved" Jews and "people of Jewish background"- and posed most questions only to the first group. As a result, most findings about belief and observance refer only to a subgroup of American Jews, making comparisons to the past impossible. We can' t afford to wait a decade before these figures are revised. The false population decline must be corrected before it further sours communal discourse. The United Jewish Communities owes it to itself and its public to step forward and state plainly what it knows to be true: American Jews are not disappearing. According to the passage, which of the following statements is NOT true about the National Jewish Population Survey？ A．It found a decline of 300,000 Jews in ten years. B．It was carded out by United Jewish Communities. C．This is the first time United Jewish Communities has made mistakes in the population survey. D．The reported decline is not reliable.
