Article: If you prefer doughnuts to dumbbells , you have a high chance of developing diabetes later in life. 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: The main idea of the passage is that _ . Yes or no, is the answer "coffee is likely to prevent diabetes"?
Yes

Article: On 15 September 1918 Lee Duncan, an American soldier, rescued a half-starved shepherd and her five puppies from a bombed dog's kennel on the battle fields ofprefix = st1 /France.Duncanchose two of the dogs, a male and female, while members of his group took the mother and the others back to camp. The only survivors over the next few months were the two pups Duncan had claimed, naming them 'Rin Tin Tin' and 'Nannette' after tiny French puppets the French children would give to the American soldiers for good luck. When the war ended, Duncan made special arrangements to take his pups back to his home in Los Angeles, but during the Atlantic crossing, Nannette became ill and died, shortly after arriving inAmerica. In 1922, Duncan and Rin Tin Tin attended an LA dog show, his dog performing for the crowd with an impressive high jump. After the show,Duncanreceived $350 for Rin's performance. That was the beginning of Rin Tin Tin's later involvement in many films and television series It happened that Warners had difficulty shooting an exterior scene with a wolf as they got into a low budget. Duncanquickly approached the director and told them that his dog could do the scene in one take. True to his word, Rin did the scene in one take. As a result, he and his dog were hired for the entire shoot of "Man From Hells River". The film was a hit and Rin Tin Tin became a box-office star. It was the first American dog movie star. It made 26 pictures for Warners while starring in his own live 1930s radio show "The Wonder Dog". At the peak of his popularity, Warners kept 18 trained stand-ins to reduce any stress on their dog star. The star dog was worthy of the honor of having its private _ to prepare daily lunches for him. As a band was playing classical music it slowly consumed a lunch of tenderloin steak. Question: Which of the following can replace "chef"? Yes or no, is the answer "cook"?
No

Q: Article: Few people realize that there is a big difference between formal English and informal English. Formal English is used for most writing, and often in public speaking and formal meetings. It pays close attention to grammar rules, because if we use proper grammar, our meaning is often more _ . Also, on important occasions, we do not want to appear uneducated or to offend others, so we are very careful about how we speak. Informal English is used in speaking or writing to our friends and family. It often does not pay such close attention to grammar rules, because when we speak or write to them, we want our words to flow quickly. Also, with our friends and family, we are usually not so worried about appearing uneducated or about offending them by how we write or speak. A big difference between formal and informal English is the use of contractions. A contraction is where we make a word shorter or where we put two words together and take away some of the letters. For example, instead of saying "do not", many people say "don't". Using contractions in our speech is fine because it sounds natural, especially when we speak to our friends. In formal writing, however, contractions are usually avoided because people might think that you have made a mistake, or that you do not know proper grammar. In the same way we might make words shorter, in informal English we often make sentences shorter as well. For example, if someone asks you your name, you will likely answer with one word: your first name. However, in formal English we usually use complete sentences. For example, we might write "My name is John". In most speaking, we may not need to use every word in a sentence because the person we are speaking to will probably still understand us. In most writing, however, every word in a sentence must be written out in order to make sure that we can be understood. Question: When we use formal English, _ . Yes or no, is the answer "we will appear educated on important occasions"?
A: No

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 _ . Yes or no, is the answer "call for better use and development of natural gas"?
(A).
No
