A:economic slack. B:continued strength. C:economic recovery. D:job security.

The housing market has been for two years propping up consumers’ spirits while the rest of the economy lies exhausted on the floor, still trying to struggle to its feet. According to the National Association of Realtors, the national median existing-home price ended the year at $164,000, up 7.1 percent from 2001. That’s the strongest annual increase since 1980.
Although residential real estate activity makes up less than 8% of total U. S. GDP, a housing market like this one can make the difference between positive and negative growth. Most significantly, consumer spending is 66% of GDP, and the purchase of a new home tends to have an "umbrella effect" on the homeowner’s spending as he has to stock it with a washer/ dryer, a new big-screen TV, and maybe a swing set for the yard.
The main factor in housing’s continued strength is a classic economic example of zero-sum boom: the persistent weakness everywhere else. As the 2003 recovery continues to be more forecast than reality. Falling stock prices raised investor appeal for U. S. Treasury Bonds, which in turn, allowed most interest rates to drift even lower. But there are not many signs that there’s a bubble ready to burst.
December’s new record in housing starts, for example, was nicely matched by the new record in new home sales. If you build it, they will buy and even if an economic pickup starts to reduce housing’s relative attractiveness, there’s no reason why modest economic growth and improved consumer mood can’t help sustaining housing’s strength. "The momentum gained from low mortgage interest rates will carry strong home sales into 2003, with an improving economy offsetting modestly higher mortgage interest rates as the year progresses," said David Lereah, chief economist at the National Association of Realtors.
Just as housing has taken up much of the economic slack for the past two years, both as a comforting investment for fretting consumers and a driver of consumer spending itself, a big bump elsewhere in the economy in 2003 could be housing’s downfall. If stocks roar back this spring, capital inflows could steal from the bond market, pushing up long-term interest rates. Or Alan Greenspan and the Fed could do the same to short-term rates, as a way to hit the brakes on a recovery that is heating up too fast. In other words, if everything possible goes wrong for housing, homeowners should have plenty to compensate them in terms bf job security and income hikes.

There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast.
Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world’s population. As society reaches these limits, economic growth can no longer continue, and th9 quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroudings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.

The passage is mainly about （　）

A:the contradiction between economists and the business community B:the present debate on economic growth C:the advantages and disadvantages of economic growth D:the importance of the debate on economic growth
