[Q]: Article: If you put all the books you own on the street outside your house, you might expect them to disappear immediately. But one man, Hernando Guanlao in Manila, tried it and found that his collections grew. He's a lovely man in his early 60s, with one ever-lasting love--books. They're his pride and joy, because, whether he likes it or not, they seem to be taking over his house. Guanlao has set up a "library" outside his home in central Manila. Readers can take as many books as they want, for as long as they want. As Guanlao says, "The only rule is that there are no rules." You might consider it would end very quickly. But in fact, in the 12 years he's been running his library. He's found that his collection has grown rather than become smaller, as more and more people help the activity. "It seems to me that the books are speaking to me," he says with a smile, "The books are telling me they want to be read." Guanlao started his library in 2000, shortly after the death of his parents. He was looking for something to honor their memory, and that was when he hit upon the idea of promoting the reading habit passed on to him from his parents. So he put the books outside the door of his house to see if anyone wanted to borrow them. They did, and they brought the books back with others to add to the collection. The library was born. The library is not advertised, but somehow, every day, a steady stream of people find their way there. To help the poorest communities in Manila, Guanlao doesn't wait for them to find him on his "book bike". He wants to set up a "book boat", traveling around the islands of Sulu and Basilan. As we sat outside Hernando Guanlao's house in the midday sun, watching people look through his collection, he thought it was worth spending all his time.

[A]: According to the passage, readers in Guanlao's library _ .

[Q]: Article: Endless playing of songs like All I Want For Christmas in shops during the festive season doesn't just drive us mad--the songs also make us more careless with our money, research has warned. While repeated performance of Jingle Bells may seem like an innocent attempt to raise customers' spirits during the nightmare of Christmas shopping, the songs also have a more delicate impact.[:ZXXK] "Background music, or 'muzak', can be used by marketers to impose cultures--such as the commercialization of Christmas--onto consumers and influence their behaviour, "experts said. Dr. Alan Bradshaw of Royal Holloway, University of London, said, "Festive jingles are force-fed to Christmas shoppers in a bid to change their mood, influence their sense of time and what sort of products they buy. In other words, this is an attempt to control your shopping habits in a way that you might hardly be aware of." "Often we are told that we have the freedom to choose where we want to shop, but during Christmas the use of music in this way is so common that our freedom to choose disappears." Dr. Bradshaw and Prof Morris Holbrook of Columbia University examined the phenomenon and found that retailers often "dumb down" the music played in shops to relax customers, meaning it is easier to control their behaviour. It is thought that slowing down the rhythm of music in shops can trick customers into thinking less time has passed, and therefore spend more time examining the shelves, for example. Some providers of background music have been known to promote their services by claiming they can boost profits by controlling the behaviour of customers. "A common trick is to take a popular current song and record an instrumental version which can be slowed down or sped up at different time of the day to influence behaviour in different ways," Dr Bradshaw said. Background music is often classed as "Muzak" in honor of the Seattle-based company which began producing its soft-sounding melodies in the 1930s.
Answer: let customers spend more time shopping
[A]: Shopkers slow down the rhythm of music in shops to _ .

[Q]: Article: The Museum of Childhood is spread over 4 floors, with the first floor acting like a balcony around the edge of the building, so you can look down over the ground floor central hall with the shop, Information Desk, and Benugo Cafe. The museum of Childhood is housed in a large Victorian building in east London. It has been on this site since 1872. It has undergone refurbishment and reopened in 2006 and an elevator now makes all floors accessible. This is not a quiet place and children are allowed to have fun here. Child safety is extremely important and a member of staff remains by the front door at all times. Also, note the "Code of Behavior" notices, which include: children under 12 must be supervised by an adult; no eating in the galleries, and no running. Toy exhibits are in glass cases and there are plenty of low-level exhibits for younger children to see. The glass cases have lots of thought-inspiring questions on them to encourage discussion between adults and children. When you or the children need some quiet time, there are sofas at either end of the second floor with reading books available.
