The headman was Augusta Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way. Soon they heard the sea. They were carrying the usual rope, and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to change its weight. It was for use over the sea. They were also carrying some bags of sand. After the sun rose, the balloon went higher. It went up to 3,000 meters, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand, but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice. At last they pulled the box into the basket. It was still snowing; so they climbed up to get away from the snow. They rose to 5,100 meters! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had travelled 1,797 kilometers from London! Question: The metal box was used for _ . - carrying the bags of sand - keeping drinking-water - carrying ropes of the basket - changing weight

Read the following article and select the best answer. Article: Time and how we experience it have always puzzled us.Physicists have created fascinating theories, but their time is measured by a pendulum and is not psychological time, which leaps with little regard to the clock or calendar.As some-one who understood the distinction observed, " _ Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age.They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass.For example, a day at the office flies compared with a day at the beach.Since most of us spend fewer days at the beach and more at the office as we age, an increase in structured tune could well be to blame for why time seems to speed up as we grow older. Expectation and familiarity also make time seem to flow more rapidly.Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real idea of when we'll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The _ of the outward journey has become routine. Thus taking a different route on occasions can often help slow the clock. When was become as identical as identical as beads on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day--to stop time, so to speak. Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn't have to be. Question: The purpose of the passage is to _ . - give various explanations about time - describe how we experience time psychologically - show the different ideas of physicists and psychologists on time - explain why time flies and how to slow it down psychologically
**Answer**
explain why time flies and how to slow it down psychologically

Read the following article and select the best answer. Article: Cooking food over a smoky fire is found everywhere in the world. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms. There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food. The second kind of solar oven is a panel cooker. It includes several flat walls, or panels, which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars. The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly. You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things. To learn more about solar cooking, you can write to Solar Cookers International. The postal address is nineteen-nineteen Twenty-First Street,...
