But if you wash down those doughnuts with at least seven cups of coffee a day, you are only half as likely as that. The finding is "quite surprising and fairly dramatic", says Bill Hartnett of UK Diabetes, although the patients' group won't be advising people to drink lots of coffee just yet. While there's little evidence that one or two cups a day is harmful, some studies suggest that heavy coffee drinkers are unusually sensitive to pain, easier to fearful disorders and can also have higher blood pressure, which increase the risk of heart disease. The study was done by Rob van Dam's team at the National Institute for Public Health and Environment in the prefix = st1 /Netherlands, which analysed the data on 171,111 men and women. The team found that those who drank seven or more cups of coffee a day were 50 percent less likely to develop type 2 diabetes than those who drank two cups of coffee or fewer a day. This was despite the fact that the heavy coffee drinkers tended to have sedentary lifestyles, which increases the risk of developing diabetes. "It's too early to get excited," warns Edwin Gale, a diabetes specialist in Britainat theUniversityofBristol. "It may just be that coffee drinkers behave differently," he says. Type 2 diabetes used to appear mainly in older people, but as levels of obesity (being fat) have increased in children, so has the disease in common. It's a serious disorder--high blood sugar levels damage many organs, and can lead to anything from blindness to kidney failure. It usually occurs when the body becomes less sensitive to insulin , the hormone that tells cells to take in too much blood glucose. Caffeine isn't an obvious remedy for type 2 diabetes, because its immediate effect is to lower sensitivity to insulin. Question: Edwin Gale's opinion _ . - agrees with that of Rob van Dam - suggests coffee drinkers obey some regulations - shows the study may be beyond the fact - tells coffee drinkers to visit doctors
shows the study may be beyond the fact

Read the following article and select the best answer. Article: World top-ranked badminton player Lin Dan said last Friday that he was a better player than Taufik Hidayat in the year of 2006 despite losing the Asian Games single title to the Indonesian Olympic champion. "I have ranked No.1 in the world for two straight years and I think people can easily come to a conclusion on who is a better player for the whole year," said Lin Dan, also known as Super Dan in the badminton world because of his marvelous performance in the sport. Hidayat beat Lin 21-15, 22-20 to give Indonesia its second gold medal in Doha on December 9, retaining his Asian Games singles title and avenging two losses to the badminton world champion. Lin, 23, led China to the men's team title after defeating Hidayat twice in three days, in the preliminary round and in the semifinals of the Asian Games. In their third meeting, Lin came up against a better-prepared Hidayat than he had encountered previously. Hidayat was cheered on by the noisy support from dancing and flag-waving Indonesian fans, who had converted the badminton arena into a national celebration even before the two players stepped onto the court. There's been a lot of acrimony between Hidayat and Lin, who this year won the single title in the world championships after former champion Hidayat crashed out in the quarterfinals. In Doha, Hidayat was quoted as calling Lin "arrogant" before the event began, but the two stars played down the rift (a situation where two people dislike each other). "It's no problem, we're close friends," said Hidayat. "The media _ it." Lin said last Friday in Beijing that he and Hidayat remain friends despite all the rumors . "There is no problem between Taufik and me although we don't talk to each other very much," said Lin. "Media tends to make up things in order to make their stories juicy." Question: What is the relationship between the two players like? - They are only opponents. - Lin looks down upon Hidayat. - They both think they are friends. - The media has worsened the relationship between them.
They both think they are friends.

Read the following article and select the best answer. Article: As demand for power and fuel grows steadily in the coming decades, we must consider every possible energy source on hand if we're to meet the world's needs. And because clean natural gas is found in great plenty, there is little doubt that it will play a major role on the world energy stage in this century, much like oil did in the last. But, like oil, gas reserves are concentrated in just a few places in the world, usually far from where they're needed most. And that's only part of the challenge. The world has had well over 100 years to search for oil and to build the necessary facilities to bring it to market; the natural gas facilities, particularly when it comes to liquefied natural gas(LNG), are not nearly as developed. So what needs to be done? On the supply side, producing nations need policies that allow for better development of their natural gas in an open, stable business environment, not _ in which the rules of the game change without warning. The governments of consuming nations, on the other hand, must make policies for sustainable development to ensure they'll have enough supplies in the future. That means building the related facilities, including LNG stations. This, in turn, will require coastal areas to allow these necessary, but not necessarily pretty, facilities to be built in their backyards. And energy companies have a responsibility to be good neighbors in those areas by operating these facilities responsibly and safely. They must also continue to put in the billions of dollars needed to build the complex transport and storage facilities required to bring more gas to market. Expanding and diversifying energy sources by using more natural gas could lead to lower fuel prices and to greater energy security. We've taken some of the steps to get started, but we need your help to get the rest of the way. Question: The main purpose of the passage is to _ . - warn people of the lack of power and fuel - discuss the importance of oil and natural gas - call for better use and development of natural gas - instruct people how to make use of energy sources
(A).
call for better use and development of natural gas
