[EX Q]: Article: Mark Twain left school when he was twelve. He had little school education. In spite of this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known to all over the world as Mark Twain, his penname. Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's care, he managed to survive. As a boy, he caused much trouble for his parents. He used to play jokes on all his friends and neighbors. He didn't like to go to school, and he often ran away from home. He always went in the direction of the nearby Mississippi. He was nearly drowned nine times. After his father's death, Mark Twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards, he became a full-time writer. In 1870, Mark Twain got married. In the years that followed he wrote many books including The Adventures of Tom Sawyer in 1876, and The Adventures of Huckleberry Finn in 1884, which made him famous, and brought him great fortune.

[EX Q]: Article: It's really a tough job for automakers doing marketing and sales in China, where competition is acute and customers have little loyalty. They have tried a range of tricks in recent years. But there should be a moral bottom line. Unfortunately, a Buick dealership used the tragedy of a two-month-old infant to advertise its cars last week on Weibo - Micro blog. And Hyundai Motor followed suit. On March 4, an SUV was stolen with the infant left inside alone in the northeastern city of Changchun. The news spread widely on Weibo after the baby's father called the local police and radio station for help. The next day it was revealed that the infant was choked to death and buried in snow by the thief. The online community expressed its deeply felt sympathy and condolences. The Buick dealership posted a photo of the baby and two of its cars on its official Weibo account to advertise its GPS system that can locate the stolen car. "A few thoughts on the Changchun stolen car and baby incident: when buying a car it's entirely OK to choose a brand with advanced technology," said the post. Though the post was made before tragic fate of the infant was known, the action generated a storm of outrage on Weibo. Some online commentators said it is "marketing at the cost of lives" and "extremely _ ." Worse was the post on Hyundai's official Weibo account that advertised the anti - theft system on its new SUV Santa Fe, an entry made after the child was known to have died. The action also enraged micro bloggers. Both posts were soon deleted. The Buick dealership made an apology on Weibo to the family of the victim and the public. But screenshots saved by users continued to be posted and the negative impact on both brands persists. The two brands probably didn't expect such a firestorm of fury from the Internet community, but they really made a big mistake sinking below the moral bottom line. They certainly ruined their own brand images. The Chinese have the same proverb as the English language - a little leak will sink a great ship. It takes decades to build the great ship of a respectable brand but it can take just a moment of negligence to make it fail completely. For those in corporate marketing, two lessons should be learned: first, be careful in the era of social media when one wrong can be easily magnified and have disastrous impacts in just a few clicks. Second and more importantly, think with your brain and heart. Never break the moral bonds of respect for human life and sympathy for our fellow man.
Question: Who is to blame for the tragedy of Changchun infant according to the passage?
Options: (A) The baby's father (B) Buick and Hyundai dealership (C) Weibo (D) Not clear
Asnwer: D
[EX A]: Yes

[EX Q]: Article: Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened for new tumors or doesn't it? While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing. In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups. It's hard to uproot deeply-held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy. A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening--especially considering the explosion of the elderly. It's not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to cover themselves from medical disputes. We need to think about the wise use of health care, which means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better."
Question: Routine cancer screening for the elderly people makes sense because _ .
Options: (A) it is believed to contribute to a long life (B) it is part of their health care package (C) they are more sensitive about the health (D) they are in greater danger of tumor growth
Asnwer: A
