Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Close relationships, thought to help communication by giving speakers a common context, are actually more likely to make _ when strangers are involved, a new study suggests. Because close colleagues and friends already share so much common knowledge that they often use short, ambiguous messages which can lead to misunderstandings. "People are so used to talking with those with whom they already share a great deal of information that, when they have something really new to share, they often present it in a way that they assume the person already knows it." says study-team member Boaz Keysar. Keysar and his graduate student, Shall Wu, trained 40 pairs of undergraduate students to memorize made-up names and descriptions of strange shapes. In each pair, the "director" had to communicate the identity of one of the 24 shapes. The partner had to use the information to choose the correct shape from a set of three images on a computer monitor. Half of the partners studied only the first six shapes, while the others learned the first 18 shapes. The directors, who had memorized all the shapes, were aware of their partners' knowledge levels of the shapes. In the pairs with the most shared knowledge, the directors were more likely to rattle off shape names, compared with pairs with little knowledge overlap , in which the directors were more likely to describe the actual shapes. Not surprisingly, participants with more shared knowledge were twice as likely to ask for clarification as those with less overlap. Language itself can be confusing. "The reason all this is happening at all is that language in general is ambiguous," said Keysar. He recalls an ambiguous billboard near a stadium holding a Rolling Stones concert that night. The billboard read, "Avoid LSD tonight." (:LSD"") Hmmm? "It was about Lake Shore Drive, and I'm sure the writer of the sign didn't realize he was being ambiguous," Keysar said. "Even though miscommunication can lead to missed meetings or deadlines, people are often unaware when their language is... Options: A ambiguous language can lead to misunderstandings B familiarity can mess up communication C accurate descriptions of identity help guess shapes D close relationships do not mean good communication Answer: B familiarity can mess up communication Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: World Expo 2010 Shanghai China is to be staged in Shanghai from May 1 to October 31, 2010. If you plan to visit the Shanghai Expo this summer, China Pavilion is a must - see area for you. China Pavilion, which is called Oriental Crown, is located at the center of the Expo site. Standing 63 meters tall, the China Pavilion takes the shape of an emperor's crown, with the upper layers larger than the lower ones. Covering 160,000 square meters in floor space, the pavilion is made up of a national hall and a regional( ) hall. Buildings on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put forward by Chinese from around the world. The pavilion has both traditional and modern features, which helps develop the theme of the 2010 Expo; "Better City, Better Life. For example, it is red in appearance, which covers the traditional Chinese culture, and it is green indoors, with the use of energy - saving techniques. The Shanghai World Expo is expected to attract 70 million visitors from across the globe. It is estimated that 400,000 people will visit the Expo and its 140 pavilions every day during the period, but the China Pavilion is only able to receive about one tenth of the total. How to hold so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent landmark. During the Expo, the main structure( ) will be used for an exhibition based on the theme of " Chinese wisdom in urban development" by explaining the values of harmony( ), nature and spirit. The three - story pavilion has three sections. The top floor's "Footprint of the East" will show some of the changes in Chinese cities. There, you can see a film which shows how Chinese cities have changed, especially in the past 30 years. According to Lu Chuan, director of the film, the scenery is like something from Lord of the Rings. On the second floor, "Journey of Wisdom" will explain China's four great inventions. And the ground's " Blossoming" City...
