What makes these places an almost universal place of interest? What makes foreign kings and queens and other important people want to visit these Disney parks? Well, one reason is the way they're treated once they get there. The people at Disney go out of their way to serve their "guests", as they prefer to call them, and to see that they enjoy themselves. All new employees, from vice presidents to part-time workers, begin their employment by attending Disney University and taking "Traditions I". Here, they learn about the company's history, how it is managed, and why it is successful. They are shown how each department relates to the whole. All employees are shown how their part is important in making the park a success. After passing "Traditions I", the employees go on to do more specialized training for their specific jobs. No detail is missed. A simple job like taking tickets requires four eight-hour days of training. When one ticket taker was asked why it took so much training for such a simple and ordinary job, he replied, "What happens if someone wants to know where the restrooms are, when the parade starts or what bus to take back to the campgrounds?...We need to know the answers or where to get them quickly. Our constant aim is to help our guests enjoy the party." Even Disney's managers get involved in the daily management of the park. Every year, the mangers leave their desks and business suits and put on special service clothes. For a full week, the bosses sell hot dogs or ice cream, take tickets or drive the monorail , and take up any of the 100 jobs that make the entertainment park come alive. The managers agree that this week helps them to see the company's goals more clearly. All these efforts to serve the public well have made Walt Disney Productions famous. Disney is considered by many as the best mass service provider in America or the world. As one longtime business... Question: Why do managers working in Disney parks wear special service clothes in the park? - Because they want to set a good example for employees - Because they want to remind themselves of their beginnings at Disney - Because they want to gain a better view of the company's aims - Because they want to replace employees on holiday
Because they want to gain a better view of the company's aims

Read the following article and select the best answer. Article: The great Snipe is a little shore bird-not one that would be considered a great athlete. However, a recent study has shown that these slightly fat birds not only fly nonstop for long periods of time during their annual migration, but do so at record speeds. The brown migratory birds that are about the size of a pigeon spend their summers in Eastern Europe and winters in Central Africa, a distance of about 2,800 to 4,000 miles. In May 2009, a team of researchers led by Dr. Raymond Klaasen from Sweden's Lund University fitted ten Great Snipes with tiny geo-locating devices that allow scientists to figure out when and where the birds travel, and let them loose. The following year they found three of the birds and took back the devices. What they discovered was quite _ . All three birds had flown nonstop to Central Africa in August of 2009-one had flown 4,225 miles in just 3.5 days. The second one had covered a distance of 3,833 miles in three days, while the third had managed to fly 2,870 miles in a mere 48 hours or two days. Even more surprising was that these birds had traveled at speeds that averaged about 50 miles per hour-making it the fastest known migration ever. While many birds migrate longer distances, they do so over a period of a few months, resting and feeding in between. However, despite the fact the Great Snipe has plenty of opportunities, it does not stop. And they do the entire flight with their own power, with no assistance from the wind. The tiny bird is able to make this unbelievable direct flight because of all the fat it gradually gathers in its body, which it then uses as fuel. Native no North Eastern Europe, Great Snipes live in marshlands and wet meadows . But they are also on the list of endangered animals because of loss of habitat. Question: What do we know about the three birds scientists found? - The second spent the least time flying - They could fly about 1,200 miles a day - The third flew the slowest among the three. - They started their journey from Central Africa
They could fly about 1,200 miles a day

(Question)
Read the following article and select the best answer. Article: Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth. Question: What is the main idea of the passage? - How to detect nuclear radiation. - How radiation kill a man. - The mystery about nuclear radiation. - Serious damage caused by nuclear radiation.
(Answer)
The mystery about nuclear radiation.
