Not too many decades ago it seemed "obvious" both to the general public and to sociologists that modem society has changed people's natural relations, loosened their responsibilities to kin and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the "obvious" is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else.
Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different style. of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers.
These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young trouble makers. Moreover, as Wirth suggested, there may be a link between a community's population size and its social heterogeneity. For in- stance, sociologists have found much evidence that the size of a community is associated with bad behavior. including gambling, drugs, etc. large-city urbanites are also more likely than their small-town counterparts to have a cosmopolitan outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so-called undesirables. Everything considered, heterogeneity and unusual behavior. seem to be outcomes of large population size.
Which of the following statements best describes the organization of the first paragraph？
A．Two contrasting views are presented.
B．An argument is examined and possible solutions given.
C．Research results concerning the quality of urban life are presented in order of time.
D．A detailed description of the difference between urban and small-town life is given.

Like a needle climbing up a bathroom scale, the number keeps rising. In 1991, 15% of Americans were obese (肥胖的); by 1999, that proportion had grown to 27%. Youngsters, who should have age and activity on their side, are growing larger as well: 19% of Americans under 17 are obese. Waistbands have been popping in other western countries too, as physical activity has dechned and diets have expanded. By and large, people in the rich world seem to have lost the fight against flab (松弛).
Meanwhile, poorer nations have enjoyed some success in their battles against malnutrition and famine. Bat, according to research presented at the annual meeting of the American Association for the Advancement of Science, it is more a case of being out of the frying pan and into the fire. The most striking example actually in the poor world comes from the Pacific islands, home of the world's most obese communities. In 1966, 14% of the men on this island were obese while 100% of men under the age of 30 in 1996 were obese.
This increase in weight has been uneven as well as fast. As a result, undernourished and overnourished people frequently live cheek by jowl (面颊). The mix can even occur within a single household. A study of families in Indonesia found that nearly 10% contained both the hungry and the fat. This is a mysterious phenomenon, but might have something to do with people of different ages being given different amounts of food to eat.
The prospect of heading off these problems is bleak. In many affected countries there are cultural factors to contend with, such as an emphasis on eating large meals together, or on food as a form. of hospitality. Moreover, there is a good measure of disbelief on the part of policymakers that such a problem could exist in their countries. Add to that reluctance on the part of governments to spend resources on promoting diet and exercise while starvation is still a real threat, and the result is a recipe for inaction. Unless something is done soon, it might not be possible to turn the clock back.
The first sentence of the passage most probably implies that ________.
A．many Americans are obsessed with the rising temperature in their bathroom
B．more people are overweighed in the United States
C．people are doing more physical exercises with the help of scales
D．youngsters become taller and healthier thanks to more activities
