"Nowadays we are talking away on the phone without meeting people," says Seung-Jae Moon. And from business conference calls to chat lines, people often imagine they would recognize the speaker if they saw him or her. Seung-Jae Moon, a linguist of Korea found that, under certain conditions, they're actually right. Moon decided to see just how close those mental pictures match up with reality and if there was any relation to how people speak rather than what they are saying. He recorded 16 Koreans, half men and half women, reading the same passage, and took a full-body photo and head shot of each speaker. Then he played the tapes for 361 Koreans and 173 Americans who did not speak Korean and asked his subjects to match up voice and picture. The Korean participants viewing full-body photos were quite perceptive. A majority linked 6 of the 8 women to the correct voice and did so for 5 of the 8 men. With the Korean group shown only faces, accuracy plummeted, but more than 20 percent of the subjects selected the same incorrect picture. The Americans showed no accuracy in matching the foreign voices to photos, but they too were consistent in their errors. That disconnection reveals conflicting ideas of physical and vocal beauty. Moon asked people to pick a favorite face and voice. Seventy percent of the Koreans picked one voice, but there was no agreement on a face. Americans didn' t agree on either count. And over 65 percent of both Koreans and Americans did not match their favorite face with their favorite voice. Moon hopes to use software to break voices into components like pitch and hoarseness to narrow down which elements trigger certain mental pictures. "If we can map which characteristics of the voice triggers what kind of linage, and it doesn't matter whether that image is the right or wrong one of the actual speaker, then we can create an image through voice,' he says. That capacity could help to create computer-synthesized... Question: Moon decided to do the experiment to _ .

Article: The Chinese put up with a lot living in the world's most populous country: standing on over-crowded trains for 40 hours; sleeping outside hospitals to secure a doctor's appointment; waiting more than a year to earn a driver's license. Add getting a U.S. entry visa to the list. Applicants here have waited as long as 60 days to secure an appointment at one of five U.S. consular locations in China that process visas. There, they're often greeted by long lines, followed by a face-to-face interview that can end badly in a matter of seconds. Now there are only about 100 U.S. visa officers in China, facing considerable challenges during the summer when tourists and students travel the most. "It's not easy work," Charles Bennett, minister-counselor for Consular Affairs at the U.S. Embassy in Beijing, said to his staff. "You're making, in some cases, life-changing decisions many times a day, and that can cause great tiredness." To adapt, US consular services expanded their hours, took on about a dozen additional staff and hope to have another 20 officers by spring. More facilities are also being expanded. Despite the shocking numbers, the embassy remains troubled by charges that it rejects applicants unreasonably and that the process is unfairly burdensome. "I'm fed up," said Wendy Liu, 24. The single woman from Beijing said she was recently refused a visa and told to re-apply when her personal life and finances were more stable. "I'll go anywhere but the U.S. now," she said. "I thought America was supposed to be a country of freedom." To visit the US, Chinese nationals must prove that they have enough money and family or business ties that make it likely they'll return to China. The Department of Homeland Security said it did not keep records on how many Chinese overstay their visas. Student visas can be refused on grounds of national security. Beijing native Tan Ge, 25, believes he was not accepted after he stated his interests in infrared technology and nanoelectronics on his application. He now studies in Canada...

Read the article and select the best answer. Article: Britain's oldest man made his first visit to London yesterday at the age of 101. Mr. John Evans had never found the time or money to make the trip from his home in Forest Fach, near Swansea. But, when British Rail offered him an all-expenses-paid birthday trip to the capital he just could not refuse. He arrived at Paddington Station and smartly turned out in his best suit, favorite Panama hat and a red rose in his buttonhole. "It's very exciting. There's no doubt about it," he said. Until yesterday he had never been far from home, except for one trip to Aberdeen. "But I've been on the seas to that faraway land called Ilfracombe 21 miles from home," he joked. Mr Evans, who spent 60 years working as a miner in South Wales, almost made the journey to London once before, at the turn of the century. "There was a trip to the White City but it was ten shillings return from Swansea -- too much I thought. All my money went to the family then," he said. During the next two days Mr. Evans will be taken on a short tour of London to see the sights. Top of his list is a visit to the House of Parliament organized by his MP, Mr. Gareth Wardell. The only arrangement he does not care for is the wheelchair provided for him if he gets tired. "I don't like the chair -- people will think I am getting old. " he said. His secret for a long and healthy life has been well publicized -- no wine, no tobacco and no anger. Before setting off from Swansea with his 76-year-old son, Amwell, he said jokingly, "I'm glad to see they've given me a return ticket. " Question: The probable explanation to Mr. Evans' long life lies in _ . Options: A: his good living habits B: his hard working for the family C: his sticking to his hometown D: his living conditions near the Swansea
