Article: A programmer and an engineer are sitting next to each other on a long flight from Los Angeles to New York.The programmer leans over to the engineer and asks if he would like to play a fun game.The engineer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks. The programmer persists and explains that the game is really easy and has a lot of fun.He explains, "I ask you a question, and if you don't know the answer, you pay me $5.Then you ask me a question, and if I don't know the answer, I'll pay you $5." Again, the engineer politely refuses and tries to get to sleep. The programmer, now somewhat anxious, says, "OK, if you don't know the answer you pay me $5, and if I don't know the answer, I'll pay you $50!" This catches the engineer's attention, and he sees no end to this torment unless he plays, so he agrees to the game. The programmer asks the first question."What's the distance from the earth to the moon?'' The engineer doesn't say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the programmer.Now, it's the engineer's turn.He asks the programmer, "What goes up a hill with three legs, and comes down on four?" The programmer looks up at him with a puzzled look.He takes out his laptop computer and searches all of his references.After about an hour, he wakes the engineer and hands him $50.The engineer politely takes the $50 and turns away to try to get back to sleep.The programmer, more than a little angry, shakes the engineer and asks, "Well, so what's the answer?" Without a word, the engineer reaches into his wallet, hands the programmer $5, and turns away and goes back to sleep.

Article: An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
Question: Why may Justin Bieber be sent into suborbital space?
Options: (A) To show his bravery and make him a role model for teenagers. (B) To arouse the American public's interest. (C) To help reform the spaceflight industry. (D) To film an advertisement about space.
Asnwer: B
Yes

Article: China news, Beijing, June 5 -- The Horizon Research Group conducted a survey about Chinese parents and their children in May last year and this year. Based on a random sampling method, the survey, done in May last year, investigated about 1,095 people living in cities such as Beijing, Shanghai, Guangzhou, Xinjiang, Jinzhong, and Luzhou. All these people were aged between 18 and 60. The survey shows that 55.5% of the parents did not know who their children's best friends were. Fathers, in particular, knew even less about their children than mothers, as the survey shows only 33.8% of fathers knew who their children's best friends were while 50.8% of mothers did so, China Youth Daily reported. Parents with little education were less concerned with their children's life, or whom their children played with. The survey shows that among parents that graduated from primary schools or without any educational background, only 33.1% knew who their children's best friends were. Among parents that had received middle school education, the related proportion reached 45.5%. This year's survey was also based on random sampling. In May 2007, the Horizon Research Group investigated some 1,456 families in Beijing, Shanghai, Guangzhou, Wuhan, Changsha, Xi'an, Chengdu and Harbin. The survey shows that children under the age of 12 play for less time with their playmates than their parents did when they were young. The survey also shows that most children at present spend only 21.9% of their time playing with their friends, while their parents spent 36.8% of their time with their playmates when they were young. Nowadays, most children spend more time with their grandparents or babysitters than with their parents.
Question: The article tells us that the two surveys show the following aspects EXCEPT that _ .
Options: (A) parents at present spend less time playing with their children than with the older generation. (B) some parents do not know their children's best friends. (C) educated parents are more concerned about their children's life than those with little education. (D) parents at present are concerned little about their children's life.
Asnwer: D
No
