Article: You've see news reports about people who need help after a natural disaster or animals in need. Or perhaps you've watched TV programs about how lonely older people can get. So what can you do about any of those things? The answer: You can volunteer. Volunteering gives you an opportunity to change people's lives, including your own. Helping others in need is such an important part of the American way of life that many high schools require their students to spend a certain number of hours volunteering in order to graduate. Volunteering isn't like school: Instead of having the choices made for you about where to go and what subjects to learn,you can choose what really interests you and who (or what) is most deserving of your time. If you like animals, help out at a local animal shelter. Most shelters depend on volunteers to keep the cats and dogs happy and well exercised. If you have a friend or who has or had a medical problem(like cancer,HIV,for example), you might be inspired to donate your time to help an organization that raises money for research, delivers meals,or offers other help to people with the illness. If you like children,there are lots of volunteering opportunities--from being a Big Brother or Big Sister to helping out in an after-school sports program. You also can: serve food at a homeless shelter; take part in a park cleanup day. And if you have more than one thing you love,you can combine the two. For example,if you love kids and are great at arts and crafts , visit your local children's hospital and offer to lead art activities for young patients. Question: We know from the passage that volunteering can _ . Yes or no, is the answer "change your life"?
No

Article: Mr. Black was the manager of a hotel in Atlanta. One weekend all of the hotels were full because of a large business meeting being held in the city. On Sunday night, three men came into Mr. Black's hotel and asked for rooms. Mr. Black told them that there were no more rooms available. The men didn't know what to do because they had no place to stay in. Mr. Black wanted to help them. He remembered that there was an empty room at the far end of the first floor -- Room 112. It was a very small room, and had rarely been used as a guest room before. So, he asked the three men if they would mind sharing that small room. They replied that they would be very satisfied so long as there was a room for them to stay in for the night. Mr. Black then told them that the room would cost them $ 30 in total. On hearing this, each of the three men gave Mr. Black $ 10 before they left for their room. However, Mr. Black soon began to think that $ 30 was really too much for that small room. He called his assistant over and said, "Here is $ 5. Give it back to the three men in Room 112. Each of them paid me $10. That's too much." The assistant took the money. While he was on the way to that small room, he thought, "How can three men divide $ 5? I'll give each of them only $ 1 and keep the $ 2 left to myself. The men will be happy to get anything back, and I can also make some money that way. After all, Mr. Black will never know anything about it." So, the assistant returned only $1 to each of the three men. Each man had first paid $ 10. After the assistant returned $1 to him, each man had actually paid only $ 9. There were three men. $ 9x3="$27." The assistant kept $ 2. $ 27 + $ 2=" $" 29. Where is the missing dollar? Question: Where is the missing dollar? Yes or no, is the answer "There is no missing dollar."?
No

Q: Article: (The Daily Mail) David Thomas failed all his maths exams and left school with no qualifications, yet this 30 - year - old fire - fighter has just gone into the Guinness Book of Records by reciting from memory 22,500 digits of the mathematical constant, pi(p). After five months of training, in which he spent ten hours a day memorizing a quarter of a million digits, David Thomas took part in a 16 - hour mental battle.Witnesses watched in awe as Thomas set a new European record, earning the title 'Most Powerful Memory in the Western Hemisphere'. David says, "When I was at school I was hopeless.I could' t remember anything, but now I can remember more facts than anyone in Europe." So how does Thomas do it? "One night I was watching a TV programme about an interview with a man called Dominic O'Brien, who had been the world memory champion five times.He used to be a gambler, and he wasn't particularly successful until he developed his own mnemonics, or mental memory aid, for each card in order to remember which cards had already been dealt and which ones hadn't." Thomas became fascinated by O'Brien's theory that anyone can improve their memory by using specialized techniques.These techniques involve linking everything to familiar people or objects. "If you want to remember a phone number for example, you have to give the numbers life.Sometimes I associate a number with a person.Number 10 for me is always the Prime Minister (who lives at number 10 Downing Street) ," explained David.If David is trying to remember facts he also links them to an image."For instance, if I was trying to memorize the name 'Tom Cruise' , I would think of his film Top Cun, and that leads me to images of guns and cruise missiles." is soon going to appear on TV's Record Breakers, and this week he is teaching memory training and speed - writing at Huddersfield University.His fees are PS600 a day.He is sure that the future holds a lot more for him than a job as a fire - fighter. Question: Why did O'Brien develop his own mnemonics? Yes or no, is the answer "To win money while playing cards."?
A: Yes

Article: BEIJING Nov. 28 (Xinhuanet) - Premier Wen Jiabao on Sunday pledged central and local government funds to provide and improve school bus services in the wake of the traffic accident that killed 19 preschool children and sparked national outrage . He urged relevant departments of the State Council to "rapidly" formulate safety regulations for school coaches, and said China will accelerate the setting up of standards on design and production. Central and local governments will share the costs on providing more school buses that meet safety requirements, the premier said. However, Wen said a lot of local governments have failed to meet the rapidly increased demand for safe school buses or established sound management systems. Officials will face investigations into their responsibility if tragedies such as the one in Gansu occur again, he warned. Yuan Guilin, an education professor at Beijing Normal University who is known for his research into rural education, has proposed that all school buses should be equipped with black boxes, adding that it is achievable and affordable. The government should also improve the wages and benefits for drivers to prevent them from taking extra jobs and often driving while tired, he said. Given that some authorities complain that they are short of money, Yuan suggested they be allowed to sell advertising space on school buses. Gan Yuanchun, who participated in a campaign to promote school bus safety, said the central government should encourage the use of smaller school buses in rural areas, as roads in remote countryside areas are not as wide as in cities. Students' parents should also be able to get involved in deciding how school buses are managed, he added. In rural areas, especially in western parts, many children are struggling to receive quality preschool education because public kindergartens are scarce and most private ones often do not have qualified teachers or hardware. Question: It can be inferred from the passage that _ . Yes or no, is the answer "The local government can deal with the problem of lacking money by some means."?
(A).
No
