PROBLEM: Article: A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years.

PROBLEM: Article: The percentage of districts that require elementary schools to teach physical education increased, to 93% last year from 83% in 2000. But just 4% of elementary schools, 8% of middle schools and 2% of high schools provided physical education each school day, as is recommended by the disease control agency. One-fifth of schools did not require physical education at all. In 2004, Congress passed a law requiring each school district to develop a "wellness policy" to promote the students' health by setting goals for nutrition education and physical activity. Those policies are just now taking effect, and some school administrators predict that the next survey will show more marked improvements. Some schools have set out to place health education on the same requirement with academics. In Los Angeles County, Sepulveda Middle School has banned soft drinks and eliminated unhealthy snacks from the school store. Salad, fruit and yogurt are always available in the cafeteria, said Patricia J. Pelletier, the principal. Nearly an hour of physical education is required daily, the school offers after-hours training in distance running, and it has started a class on healthy cooking for parents. "If kids are healthy and have healthy lifestyles, they're going to be better students," Ms Pelletier said. "They're going to be in school, and they're going to be connected with the teachers in a better way." The survey found that nearly two-thirds of schools prohibited tobacco use at all places, including at off-campus functions, up from 46% in 2000. Another finding was that the proportion of states that require middle schools to teach human sexuality grew, to 59% from 46%. The report found a variety of indications of healthier cooking in school cafeterias. 55% reported that they had removed the skin from poultry before cooking, up from 40%, and 46% now use low-fat cheeses, up from 31%. But 12% of elementary schools, 19% of middle schools and 24% of high schools offer students brand-name fast food from businesses like Pizza Hut and Taco Bell.
Question: What is the best title for this passage?
Options: (A) How to change children's eating habits (B) Improve students' physical health by developing their nutrition education (C) Only a little percentage of students are taught physical education (D) Healthy habits should be taught in schools
Asnwer: B

SOLUTION: Yes

PROBLEM: Article: Mrs. Allen's husband died ten years ago when her son and daughter were still in high school. Mr. Allen had left some money, and since Mrs. Allen had managed a bookstore before she was married, she took the money and bought a shop in town. Later she moved the shop out to the shopping center. She was a pleasant woman; she worked hard and was well-informed about books, and so the bookstore prospered and she was able to hire a friend to help her. Laura Barnes, Mrs. Allen's friend and assistant, was also a widow. She had some free time and the need for a little extra-money, and so she took the job in the bookstore. She was too clever and friendly, and the two women were well-known in the neighbourhood as "Mrs. A"and "Mrs. B".
