阅读下面的短文，然后用大约 =30个词概括其内容要点。

     The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever

invented. Much of the blood on the street flows basically from careless behavior of drivers who refuse to

respect the legal and moral rights of others. So the killing on the road may be regarded as a social problem.

     In fact, the enemies of society on wheels are rather harmless people, just ordinary people acting carelessly,

you might say. But carelessness is no excuse when one's actions could bring death or damage to others.

     Researchers have estimated that as many as 80 percent of all automobile accidents are caused due to the

psychological condition of the driver. Emotional upsets can slow drivers' judgments and reactions, and blind

them to dangers that might otherwise be obvious. The experts wam that it is important for every driver to

make an effort to keep one's emotions under control.

     Yet drivers are not the only people to blame for road accidents. Street walkers regularly break traffic

regulations. They are at fault in most vehicle walker accidents and many cyclists even be- lieve that they need

not follow the basic rules of the road.

Rarely do major diseases have a single cause. They are usually the result of a complex interaction between many factors, including genetic, environmental and lifestyle components. Many media reports, however, can tead us to believe that if we gave up something that we might otherwise enjoy, we could completely escape that particular affliction.

Clearly, this is not the case. Vegetarians die of cancer of the colon (结肠). Teetotallers die of liver complaints, including cirrhosis (硬化). People who never go out in the sun contract skin melanomas (黑素瘤). Always, there are other factors at work than the single element being examined in a scientific study.

Quite often the alleged benefits of a particular nutritional element are the result not so much of the element itself but of the lifestyle and general diet of the people who consume it most. People who eat lots of "healthy" foods, including fiber, carrots, broccoli etc. , also tend to drink less alcohol, take more exercise, avoid too many fatty foods and smoke less. Only when a study can rule out all of these other factors and often we do not know what these factors might be can we say that there is a causal link between two things. That is not to say that things like fiber and broccoli have no beneficial effects at all. But those with sedentary lifestyles cannot expect these foods to make them healthy.

There is, however, one thing which increases the likelihood of dying relatively young, even when all of the other factors have been taken into account. It is one of the biggest killers even among those who lead lifestyles which, by any criteria, are clearly healthy ones. This single, incontrovertible risk factor is that of being poor. Recent report from the Cancer Research Campaign suggested that 12 700 deaths could have been avoided between 1986 and 1990 if inequalities in cancer care did not exist in England and Wales. Comparing cancer survival rates, the study found that England and Wales fared unfavorably with Europe and the US, but the most affluent regions of these two countries exhibited similar figures to the European average.

In an attempt to counter this disparity the government has announced plans for the provision of Health Action Zones which seek to encourage greater cooperation between health and social services, targeting both rural and inner city areas. The emphasis of this new scheme however appears to focus on inadequacies within health education in these areas, rather than attacking the broader issues of social inequality.

Cancer survival rates found in the study were lower in Wales than in the US because（）

A. people in Wales eat more unhealthy food than people in the US

B. people in Wales are poorer than people in the US

C. people in Wales are richer than people in the US

D. cancers in Wales are caused by more complex factors than those in the US
