I'm taking a test and have to guess the right answer to the question after the article. Article: Research shows that humans switch from selfish to unselfish behavior when they are watched. Do you? A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box. Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow _ into humans and people respond this way unconsciously, or without realizing it. It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning. The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese. Question: According to the text, which of the following statements is true? Options: A: People pretend to behave worse when they are watched. B: Fish bite other fish in a fish tank when they are alone. C: People donatemore money when they feel they are watched. D: Soldiers fought better during World War II because of a poster.

I'm taking a test and have to guess the right answer to the question after the article. Article: University of Maryland student Ben Simon and his friends couldn't stand to see good food thrown out on their campus."We basically noticed that some of the extra food from the dining hall was going to waste at the end of the day.And we met with the dining services and asked them whether it would be okay if instead of throwing out the food we would donate it.And they were on board," he said. So 18 months ago,the students began what they call the Food Recovery Network.Each night,volunteers would show up at a campus dining hall to pick up leftovers and deliver them to area shelters and food banks.So far,they have donated more than 23 000 kilos of food that would otherwise have been thrown out. Nationwide,$165 billion worth of food is wasted each year,according to the National Resources Defense Council.Spokesman Bob Keefe says that is about 40% of the country's entire food production."If we can reduce our waste in this country by 15%,we can feed 25 million hungry Americans.That is a huge benefit.That is what programs like this Food Recovery Network are doing," he said. Christian Life Center is one of the beneficiaries of the students' efforts.Ben Slye,the senior pastor ,said,"It has been just amazing to see these students take their own time,their own vehicles and own gas money and be able to make an effort like this.Each week we are able with this food probably to feed over hundred people." The University of Maryland's Food Recovery Network now has 200 volunteers and the program has expanded to 18 schools across the country."I want to grow 18 chapters to a thousand chapters within five years.And once we get to the Food Recovery Nation being at every college campus in America,we want to expand to restaurants and farms." said Simon. The volunteers are committed to making that happen. Question: What can be the best title for the text? Options: A: College Students Rescue Leftover Food B: Battles Against the Problem of Hunger C: How to Pick up Leftovers on College Campuses D: Waste Problems in University of Maryland

I'm taking a test and have to guess the right answer to the question after the article. Article: People with mentally taxing jobs, including lawyers and graphic designers, may end up having better memory in old age, research suggests. A study of more than 1,000 Scottish 70-year-olds found that those who had had complex jobs scored better on memory and thinking tests. One theory is that a more stimulating environment helps build up a "cognitive reserve" to help buffer the brain against age-related decline. The research was reported in Neurology. The team, from Heriot-Watt University, in Edinburgh, is now planning more work to look at how lifestyle and work interact to affect memory loss. Those taking part in the study took tests designed to assess memory, processing speed and general thinking ability, as well as filling in a questionnaire about their working life. The analysis showed that those whose jobs had required complex skills in dealing with data or people, such as management and teaching, had better scores on memory and thinking tests than those who had done less mentally intense jobs such as factory workers, bookbinders, or carpet layers. While the study did not look at biological reasons for the protective effect of certain jobs, potential explanations include that structural changes within the brain mean less damage is accumulated over time. Study leader Dr Alan Gow said: "Our findings have helped to identify the kinds of job demands that preserve memory and thinking later on." "However," He added, "while it is true that people who have higher cognitive abilities are more likely to get more complex jobs, there still seems to be a small advantage gained from these complex jobs for later thinking skills." Dr Simon Ridley, head of research at Alzheimer's Research UK, said the study added to the growing evidence about factors that affected brain health as we aged. "Keeping the brain active throughout life could be helpful and different types of work may play a role. However, it's important to note that this study points to a small and subtle association between occupation and later-life cognition... Question: Which of the following about the research work is TRUE? Options: A: The research team studied both environmental and biological factors. B: The researchers filled in a questionnaire about their working life. C: The research objects included people from various jobs and of different ages. D: The research is helpful to the study of brain health and is still under way.

I'm taking a test and have to guess the right answer to the question after the article. Article: Women turn to online shopping Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping, according to a study published last week in the US. For years men have been more likely to shop on the Internet than women, but during the 2004 holiday season, 58 percent of those making online purchases were women. "It shows how mainstream the Internet is becoming," said Lee Rainie, director of the Pew Internet and American Life Project group, which carried out the study. Rainie said it was only a matter of time before women shoppers caught up with men. This is because women traditionally make decisions about spending. Users were more likely to shop online to save time. Internet users between the ages 18 and 29 were responsible for some of the most dramatic increase in the online gift-buying population this time around. However, three- quarters of the US Internet users did not buy holiday gifts online in 2004. They worried about credit card security, or just compared online prices with off-line prices, then dashed off to the shops to get the best deals. " But even if shoppers don't buy online , websites are becoming promotion tools for stores," said Dan Hess, vice president of ComScore Networks Inc. Hess said that actually most stores' websites can make customers fully believe the security of their credit card numbers. And most are able to ensure that gifts arrive on time. " It's all about making the shopping experience more efficient, more reliable and more comfortable." Hess said. Question: According to Dan Hess, shopping online _ . Options: A: is unsafe B: is convenient C: is a waste of money D: is cheaper
