PROBLEM: Article: Many of the world's pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as "population pollution." About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now. Man has been using the earth's resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man's greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man's population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
Question: The rapid increase in population is considered to be _ .
Options: (A) the increase of resources (B) population pollution (C) the development of mankind (D) the present rate

SOLUTION: B

PROBLEM: Article: It does not come as a surprise that Dubai has a growing problem with "tragic". The local rulers have explored all the conventional ways to get traffic moving again,including higher prices for parking,fuel and insurance. But at a recent conference in Hamburg, Hussain Lootah said that the city may adopt a more strict approach: setting an income level for vehicle ownership. Mr Lootah's approach is unlikely to be copied widely, but mayors of other big cities around the world are starting to think about taking severe actions of their own, including complete car bans in inner cities.But the efforts may not be enough to reduce traffic and pollution. The problems will only get worse: the number of vehicles sold globally each year will grow from around 80 million today to more than 100 million by the end of the decade, according to IHS Automotive. There are already a handful of car-free communities around the world.But these are typically small and often tourist destinations that seek to create a throwback(;) in time, such as Sark Island, in the English Channel. The largest car-free urban area is probably Venice, where it is impossible to build roads and bridges to link the more than 100 small islands the city sits on. Yet pedestrian malls and other car-free zones keep popping up in cities around the world. Some cities are considering ways to limit central city access to "green" machines, such as battery-electric vehicles. Hamburg is perhaps the furthest along. Such extreme plans may fly in a city such as Hamburg. But in many other cities the political resistance even to less far-reaching measures is hard to overcome. Michael Bloomberg, New York's former mayor, tried twice to introduce a jam charge for much of Manhattan, but his plans were rejected by state lawmakers.
Question: It is still hard to reduce traffic problems, because _ .
Options: (A) Mr Lootah's approach will be copied widely. (B) mayors take gentle measures toward them. (C) more vehicles will be sold globally each year. (D) complete car bans in inner cities are not made.

SOLUTION: C

PROBLEM: Article: Using the Internet , doctors "can answer more questions from more patients in a shorter time, " writes Dr Badal Pal, a famous doctor in Manchester, IJK. According to Pal, nearly 40% of American patients say they have used e-mail to communicate with a doctor in the past. He notes however, that although patients have such interest, only up to 2% of doctors in the United States offer e-mail services. Using e-mail, doctors can make sure of their advice and point patients to patients information materials and sources on the Internet. It's said that more than 10.000 health-oriented websites already exist now. However some people worry that widespread use of medical e-mail might set up two kinds of care--one "haves" and another for the "have-nots". But Pal points out that "In the near future nearly every library will offer (Internet and e-mail)services in the United States, " allowing even low-income patients to use such means. Pal also talks about other possible barriers to acceptance of medical e-mail. "Doctors may be unwilling to offer e-mail services for fear of increasing workload and uncertainty about the time they spent," he explained, and patients may worry that their medical information might be read by others. "But these problems can all be solved," he adds. E-mail may well help us a lot in health care, Pal concludes. "Patients want to know more than they can get in normal clinics," he points out, "and they might find communication on the information superhighway less fearful than face-to-face dialogue with their doctors."
Question: The article introduces a new way of patient-doctor communication _ .
Options: (A) by e-mail (B) by visiting websites (C) by searching the Internet (D) by using the computer

SOLUTION:
A
