Read the following article and select the best answer. Article: Throughout time, people have loved music for its ability to transport them into a world of rhythm and melody. Recently more and more hospitals and clinics have been _ the power of music -not only to comfort patients, but to help cure them as well. Welcome to the world of music therapy . After each of the two world wars, musicians visited hospitals and played instruments for injured soldiers suffering from emotional and physical pain. Today's music therapists continue this practice, playing instruments such as guitars and harps to bring comfort to their audiences. Therapist Eric Mammen encourages his patients at a children's hospital to participate with him as he plays. During visits with 13-year-old cancer patient Lawrence Garcia, Mammen encourages Garcia to beat on electric drums while he plays the guitar. The therapy won't cure his cancer, but it does, according to Garcia's mom, take away much of the boy's depression . Music therapy can put patients in better moods and ease the symptoms of depression according to the American Music Therapy Association. Other benefits include relieving pain, calming tension, aiding sleep, reducing worry or fear, and easing muscle tension. Jose Haro personally experienced the benefits of music therapy when he was recovering from heart surgery. During his recovery, he played a piano whose keys lit up, indicating which keys to touch to play along with the background music. Soon he was playing tunes and noticing something strange. "I was searching for my pain." He says of his experience, "but it was gone." While Haro's experience provides an evidence of the power of music to relieve pain, scientific research has proven music also helps patients with Alzheimer's disease and arthritis. In addition, music therapy helps premature babies. Doctors are tapping into a powerful way to teach premature babies that haven't yet learned how to suck. Doctors use a device that comforts the babies by playing music when they suck on a pacifier . Soon the babies learn to suck in return for music,... Question: According to the passage, Jose Haro _ . - went through an obvious effect of music on his recovery - was asked to play the piano with the background music - felt no pain in his surgery because of music therapy - recovered from heart disease completely
went through an obvious effect of music on his recovery

Read the following article and select the best answer. Article: Coupons to spend "How did you spend your coupons?" On their first day back to school, many students in Hangzhou greeted each other this way. The coupons referred to the 100 yuan coupons each student received form the city government before the Spring Festival holidays. Over 260,000 primary school and middle school students were given coupons. They could use them in local stores and supermarkets, or to see movies and buy books. The same coupons have also been given to low income families in Hangzhou. Other cities, including Chengdu and Nanjing, also gave coupons to their citizens. More cities are expected to follow their lead. Why are local governments doing this? These programmes are all part of a broader effort in China to increase domestic demand in the face of the global financial crisis. The crisis has seriously affected China's exports and investments . Many factories in southern cities have been closed down. Some companies are laying off workers or reducing their pay. The stock market and real estate market have been falling. In a time of financial crisis, people usually respond by saving money. They are uncertain about the future and are afraid that more difficult times may be ahead. Now many people are choosing not to spend money carelessly. Major chain stores have seen a sharp slowdown in sales, analysts say. But spending keeps an economy healthy. If people don't spend, there will be too many products in the market. Then shops will stop buying products from factories. When factories receive no orders, they close down. The workers there accordingly lose their jobs. Also, if people don't spend, the service industry suffers. The total result is that the whole economy breaks down. Issuing coupons is a practical and effective way to increase domestic demand in the current situation, said Jiang Zengwei, vice-minister of China's Ministry of Commerce. Hangzhou reported a rise in customers in local markets during Spring Festival holiday. However, issuing coupons is only a temporary measure. To increase... Question: If the government is to print a slogan on the coupons to restore consumers' confidence, what might be used to promote the idea? - Spend now, save later. - Spend money like there's no tomorrow; come on! - Spend money like it's going out of style; let's do it! - Big spender, wise spender.
(Answer)
Spend now, save later.

Question: Read the following article and select the best answer. Article: Scientists have claimed a milestone in the drive for new energy--development of the first practical artificial leaf, an advanced solar cell that imitates the process,called photosynthesis ,that green plants use to make sunlight and water into energy. "A practical artificial leaf has been a dream of scientists for decades,"said Daniel Nocera,who led the research team."We believe we have made it.The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. One can imagine villages in India and Africa soon purchasing an affordable basic power system based on this technology." The leaf is like the shape of a poker card but thinner.Placed in water in a bright sunlight,it could produce enough electricity to supply a house in a developing country with electricity for a day by splitting water into hydrogen and oxygen, which are stored in a fuel cell to produce electricity. The"artificial leaf"is not a new concept.The first artificial leaf was developed more than a decade ago by John Ttlrner.However, it was impractical for wider use,as it was composed of rare,expensive metals and was highly unstable with a lifespan of barely one day. Nocera's new leaf overcomes these problems.It is made of inexpensive materials that are widely available,works under simple conditions and is highly stable.Laboratory studies showed that it could operate continuously for at least 45 hours without a drop in activity. The key to this breakthrough is Nocera's recent discovery of several new powerful, inexpensive catalysts,which are able to accelerate the chemical reaction under simple conditions.Right now, Nocera's leaf is about 10 times more efficient at carrying out photosynthesis than a natural leaf.Yet he is optimistic that he can boost the efficiency of the device much higher in the future. Question: Daniel Nocera describes his artificial leaf as promising in _ . - making an artificial plant that can feed itself. - finding a new kind of catalyst to produce electricity. - changing the sunlight and water into electricity directly - providing electricity for the poor family at a low cost
Answer:
providing electricity for the poor family at a low cost
