PROBLEM: Article: Perhaps the most extraordinary building put up in the nineteenth century was the Crystal Palace which was built in Hyde Park for the Great Exhibition of 1851. The Crystal Palace was different from all the other buildings in the world, for it was made of iron and glass. It was one of the biggest buildings of all the time and a lot of people from many countries came to see it. Plenty of goods were sent to the exhibition from all parts of the world. There was also a great deal of machinery on show. Though in those days, traveling was not as easy as it is today, steamboats carried thousands of visitors across the Channel from Europe. On arriving in England, they were taken to the Crystal Palace by train. There were six million visitors in all, and the money from the exhibition was used to build museums and colleges. Later the Crystal Palace was moved to the South London. It remained one of the most famous buildings in the world until it was burnt down in 1936.

Options: (A) in the 1950s (B) in the 1900s (C) shortly before 1851 (D) before 1951

PROBLEM: Article: Characters in novels don't always do what the writer wants them to do. Sometimes they cause trouble, take on lives of their own, or even work against the writer. It's not just a problem for inexperienced authors: famed children's novelist Roald Dahl said he got the main character in his bookMatildaso "wrong"that when he'd finished his first version, he threw it away and started again. Of course it's not the characters' fault. The problem lies with the author. Take Stephen King, who admitted that writing working-class characters is more difficult nowadays because his own circumstances have changed. "It is definitely harder,"King said."When I wroteCarriemany years ago, I was one step away from physical labour." This is also true for characters' ages, added King."When you have small children, it is easy to write young characters because you observe them and you have them in your life all the time. But your kids grow up, it's been harder for me to write about this little 12-year-old girl in my new book because my models are gone." For other authors, such as Karen Fowler, there's one quality that can stop a character in its tracks: boredom."I had particular problems with the main character in my historical novelSister Noon,"she says."She had attitudes about race and religion that seemed appropriate to me for her time and class, but they were not attitudes I liked. Eventually I grew quite bored with her. You can write a book about a character you dislike or a character you disagree with, but I don't think you can write a book about a character who bores you." According to Neel Mukherjee, it was Adinath, a character inThe Lives of Others, who made him work the hardest."I think I struggled because it's difficult to write a character whose most prominent personal feature is weakness, as Adinath's is, without making that feature define him,"Mukherjee says. But a troublesome character is far from an unwelcome guest, he continues, arguing that "when characters work against the author they come alive and become unpredictable". "That is a fantastic thing to happen,"Mukherjee says."I celebrate it. It is one of the great, lucky gifts given to a writer."
Question: What can we infer about Stephen King's bookCarrie?
Options: (A) It was his most difficult book to write. (B) It was the first successful novel King wrote. (C) There were few children featured in the story. (D) Some of its main characters were working class.

SOLUTION: D

PROBLEM: 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 after being forced to abandon a full scholarship to Arizona State University. By its very nature, the on-the-spot process at the U.S. Embassy can feel unbearable to Chinese applicants, who are asked to take their bank statements, property deeds , marriage licenses and HUKOU, a Chinese household ID. "It made me feel very uncomfortable," said Xu Yong, 28, a journalist who needed a business visa last month to cover a conference in New York. "They made me feel like someone from a Third World country up to no good." After giving his fingerprints, Xu waited to be called for his interview, sitting in an area that was as quiet as a library. Each passing minute seemed to be as long as a century. After an hour, Xu was called with three other people to a window for their interview. Two were rejected before his turn. Then the American officer, speaking fluent Chinese, reached for Xu's paperwork, asked some simple questions and said, "Congratulations." "I was so nervous. The first thing I did when I got out was to call my mom and tell her I passed," Xu said. "She was the one who warned me it wasn't going to be easy."
