Article: Supermarkets are trying out new computers that make shopping carts more intelligent. They will help shoppers find cups or toilet soap, and keep a record of the bill. The touch-screen devices are on show at the Food Marketing Institute's exhibition here this week. "These devices are able to create value and get you around the store quicker," said Michael Alexander, manager of Springboard Retail Networks Inc. which makes a smart cart computer called the Concierge. Canadian stores will test the Concierge in July. A similar device, IBM's "shopping buddy," has recently been test-marketed at Stop & Shop stores in Massachusetts. Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf. "The whole model is driven by advertisers' need to get in front of shoppers," said Alexander." They're not watching 30-second TV ads any more." People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system that will organize the trip around the store. If you're looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them. The devices also keep a record of what you buy. When you're finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay. The new computerized shopping assistants don't come cheap. The Buddy devices will cost the average store about$160,000, and the Concierge will cost stores about $500 for each device. Question: Both of the devices can _ in a supermarket. Yes or no, is the answer "make buying much more convenient"?

Article: HANGZHOU, April 4 (Xinhua) --Another H7N9 bird flu case has been confirmed in east China's Zhejiang Province, the provincial health department said Thursday, bringing the country's total number of cases to 10. The patient is a 64-year-old man from Huzhou City. He became ill on March 29 and was admitted to a hospital in Huzhou on March 31. On Thursday, medical experts confirmed that he was infected with the H7N9 bird flu strain after the provincial center for disease control and prevention said late Wednesday that he tested positive for the virus. An investigation has found that all 55 people who had close contact with the man have not showed any abnormal clinical symptoms, the department said. So far, China has confirmed 10 H7N9 cases -- four in Jiangsu Province, two in Shanghai Municipality, one in Anhui Province and three in Zhejiang. The two patients in Shanghai and one in Zhejiang have died. Health authorities and hospitals in many Chinese provinces have been on high alert for H7N9 cases. In Nanchang, capital of Jiangxi Province, which neighbors Zhejiang, five hospitals have been selected and ordered to be ready to treat H7N9 patients, though no cases have been reported there. China's health authorities have promised transparency and cooperation to the World Health Organization (WHO) in regards to human infections of the new strain of bird flu. On Wednesday afternoon, the National Health and Family Planning Commission distributed prevention and control plans and technique directives to health institutions nationwide. "So far, the sources of infection have not been clear, but based on past experiences and recent epidemiological studies, the sources could be poultry or the secretion and excrement from poultry," according to the plan. The Chinese Center for Disease Control and Prevention said Wednesday that no human-to-human transmission of H7N9 has been discovered and no epidemiological connection between these cases has been found. Question: We can learn from the passage that _ . Yes or no, is the answer "Experts don't definitely know the sources of H7N9 bird flu."?

Yes

Article: Forbes set out to determine which master's degrees would provide the best long-term opportunities, based on salary and employment outlook. To find the mid-career average pay for 35 popular degrees, we turned to Payscale.com, which lets users compare their salaries with those of other people in similar jobs by gathering real-time salary data from its 35 million profiles. We then looked at the Bureau of Labor Statistics' employment estimate data to see how fast employment was expected to increase between 2010 and 2020 in popular jobs held by people with each degree. Finally we averaged each degree's pay rank and estimated growth rank to find the best and worst master's degrees for jobs. Physician assistant degree is at the top of the Forbes' third-annual look at the best master's degrees for jobs. Physician assistants are medical professionals who provide diagnostic and preventative health care services under the guidance of doctors. "Both an aging population and health care reform are contributing to a higher demand for health care services," says Katie Bardaro, Payscale's lead economist. They don't earn as much as doctors, but their mid-career average pay is $97,000. Another advantage of a physician assistant degree: Employment opportunities are expected to grow 30% by 2020 (from the 2010 employment numbers), according to the Bureau of Labor Statistics. By our count, computer science follows close behind as the No. 2 best advanced degree for jobs. Mid-career average pay for these grads is $109,000, sixth best out of the 35 degrees in our survey. Employment opportunities for computer science degree-holders are expected to expand about 22% between 2010 and 2020. Electrical engineering, physics and economics degrees also make the top 10, all with an average mid-career salary of more than $110,000 a year. Not all master's degree holders enjoy anywhere near such optimistic job prospects or extraordinary pay. Biology, chemistry and history degrees are toward the bottom of the list--but that doesn't mean they're... Question: Physician assistant degree ranks first on the list because _ . Yes or no, is the answer "The demand of physician assistants is expected to expand largely and they are well-paid."?

Article: Imagine that you are on a jury and you hear the testimony of an eyewitness who says that the accused person is guilty. You would probably vote to _ don't you think? Well, more often than not, you'd be wrong. A few years ago, an experiment was done on an evening news show on WNBC in prefix = st1 /New York. Viewers were shown a film of what seemed to be a mugging. In this simulation, a man snatched a woman's purse. He then knocked her down and ran face forward at the camera so that the viewers got a good look at him. Viewers were then shown a lineup of six men. They were asked to decide if the mugger was in the lineup and, if so, to tell which one he was. In effect, then, they had seven choices. The suspect was either one of the six or he wasn't even in the lineup. Of the 2,145 people who called up to respond, 1,843 were wrong. That means about one in seven was right. This is what you'd expect from random choice. Eyewitness accounts can be the most convincing evidence presented to a jury. Yet we are finding out that such accounts can be faulty. Something is just wrong. Why is this so? Recent findings have removed doubts on whether memory can last long. We also know that it can be changed by things such as leading questions. Mistaken eyewitness accounts are common. They are also the major cause of innocent persons being convicted in the United States. Question: We also know that _ can be changed. Yes or no, is the answer "memory"?
