Read the following article and select the best answer. Article: Look carefully and you'll find musicians at the top of almost any industry. The television broadcaster Paula Zahn(cello) and the NBC chief White House correspondent Chuck Todd (French horn) attended college on music scholarships; Both Microsoft's Mr. Allen and the venture capitalist Rogar McNamee have rock bands. Lorry Page, a co-founder of Google, played saxophone in high school. The former World Bank president James D. Wolfensohn has played cello at Carnegie Hall. The connection isn't a coincidence. I know because I asked. I put the question to top-flight professionals in industries from tech to finance to media, all of whom had serious ( if often little-known) past lives as musicians. Almost all made a connection between their music training and their professional achievements. Will your school music program turn your kid into a Paul Allen, the billionaire co-founder of Microsoft (guitar)? Or a Woody Allen (clarinet )? Probably not. These are outstanding achievers. But the way these and other visionaries I spoke to process music is interesting. But the key question is: why does that connection exist? Paul Allen offers an answer. He says music "establish your confidence in the ability to create." He began playing the violin at age 7 and switched to the guitar as a teenager. Even in the early days of Microsoft, he would pick up his guitar at the end of marathon days of programming. The music was the emotional analog to his day job, both of them show his different creativity. He says, "something is pushing you to look beyond what currently exists and express yourself in a new way." For many of the high achievers I spoke with, music functions as a "hidden language," as Mr. Wolfensohn calls it, one that enhances the ability to connect different or even opposite ideas. When he ran the World Band, Mr. Wolfensohn traveled to more than 100 countries, often taking in local performances (and occasionally joining in on a borrowed cello), which helped him understand "the culture of people".

(Question)
Read the following article and select the best answer. Article: In March 2012, researchers in the United States announce that they have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted under the skin. It contains the medicine, which it releases at preset times. The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses. A company called MicroCHIPS began developing the device about fifteen years ago. Last month, the company released the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis. Osteoporosis causes bones to become weak and break easily. The disorder is common among older people, especially women. Many patients have to give themselves daily injections of medicine. One type of treatment requires injections for two years. Robert farra is the president of MicroCHIPS. He says many patients stop taking the medicine because of the pain and stress of the injections and that only twenty-five percent of the patients will go through the entire twenty-four months of treatment. The microchip is a few centimeters long. It has small sections that each hold a single dose of medicine. Mr. Farra says the device has to be programmed with the times to release the drug and that doctors will be able to reprogram the device from a computer or even a cell phone. The seven women in the study were aged sixty-five to seventy. The researchers say the implants were just as effective as daily injections. And they say the dosage amounts were more exact than patients often give themselves. The microchips in the study held only twenty doses of medicine. Mr. Farra and his team are now designing a version that could hold a full year's worth of medicine. Robert Farra says, "The new version may take us two years, and then we may be required to do two additional trials, taking about four years before the device is available on the commercial scale." Question: Which is NOT the advantage of the device? - It can release exact amount of medicine. - It can free patients the pain and stress of injections. - it held only twenty doses of medicine. - It is as effective as daily injections.
(Answer)
it held only twenty doses of medicine.

Ques:Read the following article and select the best answer. Article: One stormy night many years ago, an elderly man and his wife entered the hall of a small hotel in Philadelphia. Trying to get out of the rain, they came to the front desk hoping to get some shelter for the night. "Could you possibly give us a room here?" the husband asked. The clerk, a friendly man with a winning smile, looked at the couple and explained that there were three conventions in town."All of our rooms are taken," the clerk said."But I can't send a nice couple like you out into the rain at one o'clock in the morning. Would you perhaps be willing to sleep in my room? It's not exactly a suite, but it will be good enough to make you folks comfortable for the night." When the couple declined, the young man pressed on."Don't worry about me; I'll make out just fine." the clerk told them. So the couple agreed. As he paid his bill the next morning, the elderly man said to the clerk,"You are the kind of manager who should be the boss of the best hotel in the United States. Maybe someday I'll build one for you." The clerk looked at them and smiled. The three of them had a good laugh. As they drove away, the elderly couple agreed that the helpful clerk was indeed exceptional, as finding people who are both friendly and helpful isn't easy. Two years passed. The clerk had almost forgotten the incident when he received a letter from the old man. It recalled that stormy night and enclosed a round--trip ticket to New York, asking the young man to pay them a visit. The old man met him in New York, and led him to the corner of Fifth Avenue and 34th street. He then pointed to a great new building there, a pale reddish stone, with turrets and watchtowers thrusting up to the sky."That," said the older man,"is the hotel I have just built for you to manage.""You must be joking," the young man said."I can assure you I am not," said the older man, a sly smile playing around his mouth. The older man's name was William Waldorf Astor, and that magnificent structure was the original Waldorf--Astoria Hotel. The young clerk who...
