Article: Surgical teams accidentally leave clamps, sponges and other tools inside about 1,500 patients nationwide each year. The mistakes largely result not from surgeon tiredness, but from the stress arising from emergencies or complications discovered on the operating table, the researchers reported. The study found that emergency operations are nine times more likely to lead to such mistakes, and operating-room complications requiring a change in procedure are four times more likely. It also happens more often to fat patients, simply because there is more room inside them to lose equipment, according to the study. Two-thirds of the mistakes happened even though the equipment was counted before and after the procedure, in keeping with the standard practice. Most lost objects were sponges, but also included were metal clamps and electrodes . In two cases, 11-inch retractors metal strips were forgotten inside patients. In another operation, four sponges were left inside someone. When there is significant bleeding and a sponge is placed in a patient, it can sometimes look indistinguishable from the tissue around it. The lost objects usually lay around the abdomen or hips but sometimes in the chest. They often caused tears or infections. Most patients needed additional surgery to remove the object. In other cases, patients even sensed nothing about the object, and it turned up in later surgery for other problems. To prevent such mistakes from happening, Loyola University Medical Center is becoming one of the first hospitals in the country to use sponges outfitted with bar codes. The new system was brought to Loyola through the efforts of the hospital's operating room nurses. Another effective way is to X-ray patients after surgery to reduce the likelihood of objects being left inside patients. Question: What is the best title for the passage? Yes or no, is the answer "A Mistake in the Operating Room"?
Yes

Q: Article: Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman Empire. But when the empire broke down,this kind of tourism stopped. In the early 17th century, the idea of the "Grand Tour" was born. Rich young English people sailed across the English Channel .They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The "Grand Tour" was an important part of young people's education--but only for the rich. In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to" take the waters". They believed that the water there was good for their health. So large and expensive hotels were built in these towns. In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier. Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far away countries. The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them. Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything--plane tickets, hotel rooms, even food--and tourists pay for it all before they leave home. The package tour and modern tourist industry was born. The first travel agency in China was set up as early as 1949.But tourism did not take off until 1978.In 2002,the industry was worth 500 billion yuan and became an important part of China's social development. Question: In the early times, the travelers _ . Yes or no, is the answer "had lots of money"?
A: Yes

Article: Eddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada. It all started when Graham Broad, a professor at the University of Western Ontario, found McKay's name in a footnote in a book about university history. McKay was included in a list of university alumni who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad's glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. "After looking for him all day, there he was, staring up at me out of the exhibiting case," said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view. Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there's more to his story. "For a brief time in 1916 he was probably the most famous pilot in the world," says Broad. "He was credited with downing Oswald Boelcke, the most famous German pilot at the time." Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane. McKay's war records were destroyed during a World War II air bombing on London -- an explanation for why he was all but forgotten. But now, thanks to the efforts of Broad and his students, a marker in McKay's memory was placed on the university grounds in November 2007. "I found my eyes filling with tears... Question: What did the students find out about McKay? Yes or no, is the answer "He trained pilots for some time."?
