Article: Once the 2008 Olympic Games finishes, the drums and trumpets of the competitions would also stop. But would the city remain as lively as it would be after this world event? Investment sustainability and high demand are two highly invaluable economic concepts that can be looked at in order to ensure post-Olympics flourish, or perhaps, an even better future for Beijingers. Naturally, an economic downturn occurs in an Olympic host city once the major event finishes. Renmin University Professor Jin Yuanpu noted that a global event like this would put Beijing into a position of large importance in the international stage. But after this event, who would use the heavily-funded equipment and public and private investments left in the city? Various economists argued that a meltdown is highly unlikely. Jonathan Anderson, UBS Asia economist, suggested that the negative effects of the end of Beijing Olympics 2008 on the entire country aren't important compared to previous host cities. China is such a huge economy that the conclusion of the Olympics games is the same as an ant-bite on a dragon. But what about post-Olympics Beijing? Retired Headmaster of Peking University, Li Yining, noted that a long-term civil demand growth and a popular desire by companies to adopt careful financial management decisions can lead to continued investment growth. Even though demand in some departments of the economy would drop in the short-run, creativity, practicality and innovation would be the key factors that would continually enhance the city's image and flourish long after the Olympics in the city has ended. So what's next for Beijing after the Olympics? Well, it's business as usual... Question: Which one of the followings is the author's idea? Yes or no, is the answer "Beijing's economy will go on as usual."?
No

Article: One in five people carry a 'smart gene' variant linked to long lifespan, bigger forebrains and enhanced mental ability, researchers have found. 'We've known for a long time that people lose cognitive abilities as they age, but now we're beginning to understand that factors like KLOTHO can give people a boost in aging. Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer's disease ," said senior author, Dena Dubal of University of California. The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes. About one in five people carry a single copy of the varian, known as KL-VS,which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function. A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan. In the new study scientists scanned the brains of 422 men and women aged 53 and over who were also tested for the KLOTHO gene. They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age. Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time. Researcher Dr Jennifer Yokoyama said, " The brain region enhanced by genetic variation in KLOTHO is vulnerable in aging and some mental disease. In this case, bigger size means better function. It will be important to determine whether the structure increase associated with carrying one copy of KL-VS can _ the cognitive shortage caused by disease."[:] People who have one copy of a variant KL-VS tend to live longer and have lower chances of suffering a stroke ,whereas people who have two copies may live shorter lives and have a higher risk of stroke. Question: If a person carries two copies of the gene variant, he/she may _ Yes or no, is the answer "have a shorter lifespan"?
No

Q: Article: Does eating a good breakfast improve school study? A study of more than 1,000 pupils in the city of Lawrence suggests it does. Youngsters who took part in the breakfast program improved their scores in the tests much more than those who didn't. Among those who attended the program, fewer were found late for school than those who didn't. And much fewer were found absent from their classes. "Starting the day with a meal appears to be quite helpful," says Amy Sampson, a research professor, who carried out the experiment on the students for a year. Students who miss breakfast may be losing out on important nourishment in fruit, milk, bread and so on. If you are in a hurry in the morning, get you some pieces of bread with some fruit or yogurt. In that case, you won't have to go to the selling machines for some chips or candy bars. Question: How many students in primary school are interviewed in Lawrence. Yes or no, is the answer "over 1000"?
A: No

Article: Global warming has a great influence on species all over the world. Polar bears are particularly at risk because their habitat is increasingly threatened by global warming. Lots of scientific research has shown that polar bear numbers are on the decline, and that if action is not taken quickly, polar bears may die out from the Earth. Pack ice is decreasing globally. In the wild, polar bears spend much of their lives wandering pack ice in search of food. In 2009, several polar bear deaths by drowning were recorded, which had never been heard of before. The polar bears had been trapped on isolated areas of floating ice, and had tried to swim for land. Due to the shrinkage of the ice, the polar bears tired and drowned before reaching the shore, though they are rapid and aggressive swimmers. This problem will only grow as the pack ice shrinks. The shrinkage of the ice has other consequences for polar bears. They are losing their natural prey , who are also affected by the shrinkage in habitat. Land animals also do not provide the high-fat diet that polar bears need, which will lead to starvation. Starving mothers will not be able to provide their babies with the nutrition they need, which will further contribute to the decline in polar bear numbers. While searching for food and habitat, polar bears have also fought with humans. With the disappearance of the sea ice, polar bears have begun to show up around inhabited areas looking for food and shelter. But they often end up being killed by hunters because they present a threat to human communities. The combination a deadly factors brought about by global warming put polar bears at a very high rate of risk. A global effort is needed to act against global warming before it is too late for polar bears, as well as many other species that call Earth home. Question: The reason why several polar bears died in 2009 is that _ . Yes or no, is the answer "there was no ice for them to land on"?
(Answer)
No
