Ques:Article: In Google's vision of the future, people will be able to translate documents instantly into the world's main languages with machine logic, not expert linguists, leading the way. Google's approach, called statistical  machine translation, differs from past efforts in which it does without language experts who program grammatical rules and dictionaries into computers. Instead, they feed documents humans have already translated into two languages and then rely on computers to decide patterns for future translations. Though the quality is not perfect, it is an improvement on previous efforts at machine translation, said Franz Och, 35, a German who heads Google's translation effort at its Mountain View headquarters south of San Francisco. "Some people who have been in machine translations for a long time see our Arabic-English output, and then they say, that's amazing; that's a breakthrough ." Said Och. "And then other people who have never seen what machine translation was read through the sentence and they say, the first mistake here in Line Five-it doesn't seem to work because there is a mistake there." But for some tasks, a mostly correct translation may be good enough. Speaking over lunch this week in a Google cafeteria famed for offering free, healthy food, Och showed a translation of an Arabic Web news site into easily digestible English. Two Google workers speaking Russian at a nearby table said, however, that a translation of a news site from English into their native tongue was understandable but a bit awkward. Och, who speaks German, English and some Italian, feeds hundreds of millions of words from parallel texts such as Arabic and English into the computer, using United Nations and European Union documents as key sources. Languages without considerable translated texts, such as some African languages, face greater obstacles. "The more data we feed into the system, the better it gets." said Och, who moved to the United States from Germany in 2002. The program applies statistical analysis, an approach... Question: Statistical analysis in this passage is conducted by   _  . Yes or no, is the answer "counting how frequently a word is used in the language"?

Ques:Article: There was once a king who had a wise advisor. The advisor followed the king everywhere and his favorite piece of advice to the king was "Everything happens for the good." One day the king went hunting   and had a small accident. His foot was injured. Fortunately, he was not badly injured but as always he was forced to ask his advisor what he thought about the accident, to which the advisor replied, "Everything happens for the good." This time the king was really angry and put his advisor in prison  . The king then asked his advisor, "Now, what do you think?" The advisor again answered, "Everything happens for the good." About a week later the king went on another hunting trip. As it turned out the king was caught by some cannibals   and taken to their camp where he would be prepared to be their evening meal. Before putting him into the cooking pot, he was examined and the cannibals realized that the king's foot was injured. They decided to throw him back into the forests. It is the tradition for the cannibals not to eat anything that was in any way injured. It is true that everything in our lives happens for a purpose, and most often for our own good. If you think about it, all our past experiences actually happened to bring us to where we are today and make us a better person. So whatever challenges that we may face today, consider it happening to bring us to the next level. Question: By telling the story, the writer   _   . Yes or no, is the answer "wants us to think positively"?

Ans:Yes

Ques:Article: Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be "like a magic carpet...You could fold it up and put it into your pocket or handbag". Then he paused: "But you'll always be limited by the size of the wheels. And so far no one has invented a folding wheel." It was a rare -- indeed unique -- occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout's Wonderful Bag, a leather case. Grout's aim: to solve the problems of carrying a bike on a train. Now doesn't that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout's day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn't do the same with a wheel fitted with a one-piece inflated   tyre. So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse  . Throughout, the tyre remains inflated. Will the young Fitzsimons's folding wheel make it into production? I haven't the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It's as silly a concept now as it was 100 years ago: there's plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than PS1,000 that can be knocked down so small that it can be carried on a plane -- minus wheels, of course -- as hand baggage. Folding wheels would make... Question: Which of the following would be the best title for the text? Yes or no, is the answer "Progress in folding bike design"?
