Read the following article and answer the question. Article: Betty and Harold have been married for years .But one thing still puzzles old Harold .How is it that he can leave Betty and her friend Joan sitting on the sofa ,talking ,go out to a ballgame ,come back three and a half hours later ,and they're still sitting on the sofa ? Talking ? What in the world ,Harold wonders ,do they have to talk about ? Betty shrugs .Talk ? We're friends . Researching this matter called friendship ,psychologist Lillian Rubin spent two years interviewing more than two hundred women and men .No matter what their age ,their job ,their sex ,the results were completely clear :women have more friendships than men ,and the difference in the content and the quality of those friendships is "marked and unmistakable ." More than two -thirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman .Yet three-quarters of the single women had no problem naming a best friend ,and almost always it was a woman .More married men than women named their wife/husband as a best friend ,most trusted person ,or the one they would turn to in time of emotional distress ."Most women ,"says Rubin ,"identified at least one ,usually more ,trusted friends to whom they could turn in a troubled moment ,and they spoke openly about the importance of these relationships in their lives ." "In general,"writes Rubin in her new book ,"women's friendships with each other rest on shared emotions and support ,but men's relationships are marked by shared activities." For the most part ,Rubin says ,interactions between men are emotionally controlled -a good fit with the social requirements of "manly behavior ." "Even when a man is said to be a best friend ,"Rubin writes ,"the two share little about their innermost feelings .Whereas a woman's closest female friend might be the first to tell her to leave a failing marriage ,it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on...

OPTIONS:
- he is treated as an outsider rather than a husband
- women have so much to share
- women show little interest in ballgames
- he finds his wife difficult to talk to

Read the following article and answer the question. Article: A new study found that inner-city kids living in neighborhoods with more green space gained about 13% less weight over a two-year period than kids living among more concrete and fewer trees. Such findings tell a powerful story. The obesity epidemic began in the 1980s, and many people think it results from increased portion sizes and inactivity , but that can't be everything. Big Macs and TVs have been with us for a long time. "Most experts agree that the changes were related to something in the environment," says Thomas Glass of the Hopkins School of Public Health. That something could be a shrinking of the green. The new research, published in the American Journal of Preventive Medicine, isn't the first to associate greenery with better health, but it does get us closer to identifying what works and why. At its most straightforward, a green neighborhood simply means more places for kids to play -- which is important since time spent outdoors is one of the strongest links to children's activity levels. Glass warns that most studies don't necessarily prove a link between greenness and health, but they're helping _ action. In September the U.S. government approved the No Child Left Inside Act to encourage public initiatives aimed at exposing kids to the outdoors. Finding green space is, of course, not always easy, and you may have to work a bit to get your family a little grass and trees. If you live in a suburb or a city with good parks, take advantage of what's there. Your children in particular will love it -- and their bodies will thank you. Question: What might be the best title of the passage? Answer:

OPTIONS:
- The obesity epidemic
- Slimmer in the grass
- Causes of obesity
- Prevention of obesity

Answer: Slimmer in the grass

Read the following article and answer the question. Article: In the past few years development in medical technology has made it possible for people to live longer than in the past. New medicines and machines are being developed every day to extend life. However, some people, including some doctors, are not in favor of these life extending measures, and they argue that people should have the right to die when they want to. They say that the quality of life is as important as life itself and that people should not be forced to go on living when conditions of life have become terrible. They say that people should be allowed to die with dignity and to decide when they want to die. Others argue that life under any conditions is better than death and that the duty of doctors is always to extend life as long as possible. And so the argument goes on and on without a final answer. Question: Which of the following statements is true according to the passage? Answer:

OPTIONS:
- Most of the medical workers join in the argument.
- The argument has ended in favor of the patient.
- The argument hasn't ended yet.
- The quality of life is not as important as life itself.

Answer: The argument hasn't ended yet.

Read the following article and answer the question. Article: Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet's power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks. Companies are trying to offer an alternative, clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids . The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030. When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps. Question: Which of the following statements is NOT true according to the passage? Answer:

OPTIONS:
- Lifton's Medis Technologies is tapping into fuel cells and solar panels.
- The fuel cell has been around for about 150 years.
- The fuel cell's commercial development did not begin until the 1960s.
- When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.

Answer:
When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.
