Article: New findings suggest that brainy card games such as contract bridge may temporarily raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased level of immune cell, according to research reported last week. A researcher, Diamond, studies bridge players from a woman's bridge club. She chose bridge players because the game includes skills stimulating a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system. The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland and used by the immune system against diseases. The T cells count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology , whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated systems. What isn't clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It's also not clear whether the increase in T cells could finally be targeted against special illness. Question: Diamond chose to study bridge players for the research because _ . - the players are good friends of hers - she loves playing bridge - this game stimulates a part of the brain that has something to do with immune system - She is a clever manager, who operates her bridge club well
this game stimulates a part of the brain that has something to do with immune system

Article: The head of the World Health Organization (WTO) yesterday warned of worsening health in the country's vast rural areas while praising the government for its commitment on improving healthcare in the countryside. "The health indicators have failed to improve in pace with economic indicators." said Margared Chan when addressing a conference on rural primary healthcare in prefix = st1 /China. "The health gap between rural and urban areas has grown even wider and health in parts of rural China is deteriorating ,"she said, adding medical costs are rising faster than the growth of per capital income in rural areas. She said she appreciated the government's efforts and plans to build a medical system for all people. Saying "when fair and accessible public health services become the clear targets of a country's public health policy, people's health will improve." The WTO chief said she noticed that the tasks on improving people's well-being in the report by Party chief Hu Jintao at the 17thNational Congress of the Communist Party of China included a basic medical insurance system for urban dwellers and a cooperative medical care system in rural areas. She said recent WTO research has found that diseases are the source of poverty for 30 to 50 percent of the rural population of 737 million. A growing number of rural people, especially the aged, are suffering from various diseases; however, few have access to decent healthcare, she told the conference. Chan criticized the practice of allowing healthcare services to be commercialized in rural areas, warning it will cause the patients more suffering. The government has pledged to provide its population with basic medical care by 2020. It's expanding medical care through the Rural Cooperative Medical Scheme, a plan under which subscribers are provided with 50 yuan($6.4) per person--20 yuan ($2.6) each from the central and local governments and 10 yuan ($1.3) from the individual. Vice-Minister of Health Chen Xiaohong said nearly 85 percent of... Question: Which of the following statements is WRONG? - Diseases are the source of poverty for the rural population - About 200 million of the rural population are poor because of diseases. - The government has taken some measures to improve the rural healthcare. - The local governments will give 20 Yuan to each rural person
About 200 million of the rural population are poor because of diseases.

Q: Read the following article and select the best answer. Article: Residents along Australia's east coast awoke in the morning to an orange sky as winds swept millions of tons of red dust from the country's inland and dumped it on Sydney. Tanya Ferguson,living in Sydney,saw that the room was completely orange.She thought there was a bush fire.But when she went outside,the entire city was covered in a film of orange dust. "It was like being in the outback ,but it was right here in the city,"she said On that day,a big dust storm swept through Sydney.It covered the city in orange dust for about eight hours,making landmarks such as the Sydney Opera House and Harbor Bridge invisible. The storm affected the transportation system.Flights were delayed.Roads were busy as drivers struggled in the difficult conditions.Children and the elderly were told to stay indoors until the dust had cleared.Later strong winds blew it out to the sea and up the coast. No one was hurt in the storm,though health officials answered hundreds of calls from people with breathing difficulties.Emergency services responded to hundreds of calls about tree branches brought down by strong winds. Dust storms are common in the Australian outback,where the land is arid .But the storms rarely reach the coastal regions. Officials said it was the worst dust storm of the past 70 years.Air pollution levels were 15,500 micrograms of pollutants per cubic meter. "On a clear day the pollutants are around 10--20 micrograms per cubic meter,"said Chris Eiser of the NSW department of the environment. Experts said that dry conditions in the outback and strong winds caused the sandstorm. "Ten very dry years over inland southern Australia and very strong winds have combined to produce the storm,"said Nigel Tapper,an environmental scientist at Monash University, Australia. Question: Which of the following is TRUE? - The dust storm didn't blow up to the coastal regions of Australia. - The level of air pollution was very high due to the dust storm. - People called the emergency service because they had got lost. - Children stayed indoors for the schooling had been cancelled.
A: The level of air pollution was very high due to the dust storm.

Q: Read the following article and select the best answer. Article: Children who are raised in households with dogs during their first year of life may have a lower risk of asthma a few years later, a new study suggests. In the study, the researchers looked at early exposure to dogs and farm animals and the rate of asthma among about 276,000 school-age children in Sweden. Among the school-age kids in the study, those who had been exposed to dogs during their first year of life were 13 percent less likely to have asthma at age 6. The researchers said they don't know for sure what exactly may explain the relationship between early exposure to animals and a reduced risk of asthma."It might be due to a single factor, or more likely, a combination of several factors related to a dog ownership lifestyle or dog owners' attitudes, such as kids' exposure to household dirt and pet dust, time spent outdoors or being physically active,"Fall told LiveScience."As a parent in a dog-and-baby household, it is nearly impossible to keep everything clean, and maybe this is a good thing for your baby's future health." Currently, one of the main hypotheses that aim to explain the link between a lower risk of asthma and early exposure to pets is that"kids in animal environments breathe air that contains more bacteria and bacterial fragments, which actually could lower their risk of asthma,"she said. Previous research on having pets and the risk of asthma in kids has mixed results. For example, the results of a 2001 review of previous studies suggested that exposure to pets was linked to an increased risk of asthma in children. But a 2012 review suggested that exposure to pets, especially dogs, was tied to a decreased risk of asthma and allergies in childhood. "My take-home message from this study is that parents at this point do not need to worry about keeping their dog when expecting a baby for fear of asthmatic disease,"Fall said."I do want to be clear that this recommendation is valid only for families without a child already having allergies. If they already have a furred-animal-allergic... Question: According to the passage, the school-age kids exposed to pets . - will be more caring - will grow up more happily - are less likely to have asthma - are probably behave better in school
