of debt. the conversation is almost always about student loan debt. But theres a growing body of evidence suggesting that todays young adults are also drowning in credit-card debt—and that many of them will take this debt to their graves. More than 20% overspent their income by more than $ 100 every single month. Since they havent built up their credit histories yet. its a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt. Although many young people blame "socializing" as a barrier to saving money, most of them arent knocking back $20 drinks in trendy(时尚的)lounges. Theyre struggling with much more daily financial demands. To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isnt sustainable in the long run. and its going to put a huge drag on their spending power even after they reach their peak earning years, because theyll still be paying interest on that bottle of orange juice or box of spaghetti(意式面条)they bought a decade earlier. A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups, and that theyre slower at paying it off. " If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future." warns Lucia Dunn, professor of economics at Ohio State. "If our findings persist, we may be faced with a financial crisis among elderly people who cant pay off their credit cards. " Dunn says a lot of these young people are never going to get out from under their credit card debt. "Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks."

on, having outgrown the available food supplies. Today, a century and a half later, there are still experts who forecast the same global disaster—unless urgent measures are taken to prevent it. By the end of the present century there may well be over five thousand million people living on this globe, an increase of over fifty percent on todays figure. In order to keep pace with this increase in mankind the farmers of the world will have to step up their production of food by at least two percent every year. Such a rate of increase has never been maintained in any country by conventional methods of agriculture, despite modern mechanization and the widespread use of fertilizers. There are no large worthwhile reserves of potential farmland remaining, and good fertile land is continually being changed into industrial use. Moreover, erosion of the soil takes a constant toll (损失). Intensive research, carried out over many years in all manners of climate conditions, has produced a revolutionary method of growing crops without using any soil at all. Hydroponics (水栽 法), as this technique is called, may well be the answer to all our food worries; already it has accomplished wonders in producing huge crops. Hydroponics was once a complicated and expensive business, now it is well out of the experimental stage. Labor costs are far lower than when normal methods of agriculture are employed. In fact, it is a completely automatic system. There is no hard manual work, no digging or ploughing, and no weeding to speak of. Yields can be far higher than they are in soil.

Which of the following best sums up the whole passage？

A．Malthus" prediction has been proved to be correct by modern experts.

B．Hydroponics is a new development in agriculture.

C．Hydroponics may be the answer to the world food shortage in the future.

D．Conventional methods of agriculture should be improved so as to step up food production by two percent every year.
