Article: The English expect each other to observe the rules of queuing, feel highly offended when these rules are broken, but lack the confidence or social skills to express their annoyance in a straightforward manner. In other countries, this is not a problem: in America, where a queue-jumper has committed a kind of rudeness rather than a sin, the response is a loud warning: the offender is simply told "Hey, you, get back in line!" or words to that effect. On the European continent, the reaction tends to be loud and argumentative; in some other parts of the world, queue-jumpers may simply be pushed back into line. Ironically , it is only in England, where queue-jumping is regarded as deeply immoral, that the queue-jumper is likely to get away with the offence. Only rarely do the English actually speak up and tell the jumper to go to the back of the queue. Queuing is almost a national pastime for the English, who automatically arrange themselves into orderly lines at bus stops, shop counters, ice-cream vans, entrances, exits, and lifts. In 1946, a Hungarian humorist described queuing as English "national passion". "On the continent," he said. "if people are waiting at a bus stop they walk around in a seemingly relaxed fashion. When the bus arrives they make a dash for it...An Englishman, even if he is alone, forms orderly queue of one." In an update over thirty years later in 1977 he confirmed that this was still the case. After nearly another thirty years nothing much seems to have changed. In many cases, queue-jumping is effectively prevented by non-verbal signals alone. When someone is considering jumping a queue, the queuers will start glancing at him sideways, through narrowed, suspicious eyes. Then they move a bit closer to the person in front of them, just in case the jumper might try to insert himself in the gap. Frowns, glares, and raised eyebrows -- accompanied by heavy sighs, pointed coughs -- are usually the worst that the person will suffer if he jumps a queue. Faced with all this, the jumper will think better of it and withdraw to the back of the queue.

In America and other European countries, queue-jumpers_.

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.
Answer: must help increase the collection

Ex Output:
According to the passage, readers in Guanlao's library _ .

Article: Professor Reason recently persuaded 35 people to keep a diary of all their absent-minded actions for two weeks. When he came to analyze their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups. One of the women, for instance, on leaving her house for work one morning threw her pet dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People programme themselves to do certain activities regularly." It was the woman's custom every morning to throw her dog two biscuits and then put on her earrings. "But somehow the action got reversed in the programme." About one in twenty of the incidents the volunteers reported were these "programme assembly failures." Twenty percent of all errors were "test failures" -- mainly due to not verifying the progress of what the body was doing. A man about to get his car out of the garage passed through the back yard where his garden jacket and boots were kept, put them on -- much to his surprise. A woman reported, "I got into the bath with my socks on." The commonest problem was information "storage failures". People forgot the names of people whose faces they knew, went into a room and forgot why they were there, mislaid something, or smoked a cigarette without realizing it. The research so far suggests that while the central processor of the brain is liberated from second-to-second control of a well-practiced routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be gotten by another frequently and recently used programme, resulting in embarrassing errors.
Answer: sort and explain some errors in human actions

Ex Output:
The purpose of the professor's research is to _ .
