Question: Write a multi-choice question for the following article: Article: Some people may be born happy, while others are genetically negative, scientists have suggested in a study published late February in a British journal. Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter   serotonin works within the brain. Serotonin, a hormone  , passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant   drugs regulate serotonin levels.    Scientists had also identified three variants   of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers.    Researchers from the University of Essex in Britain showed participants a series of images, which were divided into three kinds: negative ones aimed at inspiring fear or stress such as a snake or person about to commit suicide, pleasant ones and neutral   ones.     The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.    In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff.     Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.
Ans: Question: Which of the following statements is true about "happiness workshops"?Options:A Most people believe that they are a waste of money.B They will be beneficial in the long run.C The purpose of "happiness workshops" is to teach all Australians to be happy.D They are organized in the belief that happy staff can work more efficiently.Answer:D

Write a multi-choice question for the following article: Article: The horsepower was first used two hundred years ago. James Watt had made the world's first widely used steam engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring power.     Watt decided to find out how much work one strong horse could do in one minute. He called that init one horsepower. With this unit he could measure the work his steam engine could do.     He discovered that a horse could lift a 3,300-pound weight 10 feet into the air in one minute. His engine could lift a 3,300 pound weight 100 feet in one minute.     Because his engine did ten times as much work as the horse, Watt called it a ten-horsepower engine.
Ans: Question: What does one horsepower mean? It means   _  .Options:A one horse's powerB what one strong horse can do in one minuteC what one horse can do in a dayD what work one horse can do as much as possibleAnswer:B

Write a multi-choice question for the following article: Article: After numerous warnings over the years, you thought coffee probably had a negative effect on your health. Perhaps the drink is not so bad after all. The new study, conducted by the National Cancer Institute (NCI), has been published and suggests that coffee does not have a harmful effect on your health. Researchers suggest, based on data examined, older adults who drink a lot of coffee, have a lower risk of death when compared to their non-drinking coffee peers. The team of researchers conducting the study analyzed data on 400,000 U. S. men and women,aged 50 to 71 years; the individuals had participated in the NIH-AARP Diet and Health Study. This study started in 1995-1996 and was tracked until the day a participant passed away, or Dec. 31, 2008. According to a press release on the report, researchers shared that coffee drinkers are "less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the relationship was not seen for cancer." Results indicated participants that drank three or more cups of coffee a day reduced their risk of death by 10 percent. Based on the findings that both caffeinated and non-caffeinated coffee found similar results, researchers are thinking caffeine is not the protective ingredient , although which ingredient in coffee might be, they are not sure. Researchers indicate that despite these observational findings, they caution  it is not clear whether or not drinking coffee actually extends life expectancy. "Coffee is one of the most widely drunk drinks in America, but the relationship between coffee consumption and risk of death has been unclear. We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes," said Neal Freedman, Ph. D., Division of Cancer Epidemiology and Genetics, NCI. "Although we cannot infer a relationship between coffee drinking and lower risk of death, we believe these results do provide some comfort that coffee drinking does not...
Ans: Question: What can we infer from William's words?Options:A People should take advantages of drinking coffee.B People should carry out more related and effective studies.C People should drink more caffeinated coffee.D People should analyze the cause of human death.Answer:B

Write a multi-choice question for the following article: Article: When you choose a freezer, remember it's probably going to be with you for a long time. So it's important to know which freezer is right for your needs.    First, decide if you want an upright or chest model. Uprights are more convenient. Their storage space is more accessible and they take up less floor area. However, chest models are more energy-efficient because less cold air escapes when they are open.    If you are buying an upright, you'll have to choose between frostless  or manual  defrost . Chest freezers are always manual. Frostless freezers automatically defrost at present intervals  and remove the water. Manual models must be defrosted by hand every few months or whenever frost pile up to about a quarter of an inch.    To help your freezer reach a ripe old age, try to find a spot that's cool, dry, and away fromdrafts . Drafts and heat will raise the freezer's cabinet temperature, which makes it work harder to keep cool. That means wasted energy. That means wasted energy and a shortened life.    Dry air is important because highhumidity  can cause the freezer to rust outside and frost up inside. With proper care, a freezer can serve you for 15 years or more. Regular cleaning and simple maintenance will help it maintain a zero-degree temperature and keep it smelling fresh and looking almost new.    Frostless models requires less care than manual defrost freezers. The inside of a frostless unit should be washed periodically with warm water and baking soda or a mild soap, rinse, and dried.   Good habits go a long way toward a freezer that runs efficiently. To get the most from your freezer, check regularly to make sure it's providing a true zero-degree temperature.   Keep the freezer at least three-quarters full. The emptier it get, the more energy is wasted. If more than three pounds of food per cubic foot of storage space is added every 24 hours, the resulting high or low temperature can damage the food.

Answer: Ans: Question: According to the passage, choosing the best place for your freezer means  _  .Options:A putting it in an unheated garage if possibleB locating it near a stove if it is a manual-defrosted modelC trying to keep it away from heat, drafts, and humidityD locating it as close as possible to the kitchen doorAnswer:C
