- It is the jet stream that affects how fast airplanes fly.
- Planes go slower when they are moving with the wind.
- It takes more time to fly from NY to London than from London to NY.
- The jet stream always blows from the east to the west across the Atlantic.

Read the following article and answer the question. Article: Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string , it goes around in a circle until you let go of the string. Then it flies off in a straight line. 'Switching off' gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly _ upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. Question: What information can we get from the first passage? Answer:
****
A: It is the jet stream that affects how fast airplanes fly.

Read the following article and answer the question. Article: It's interesting that the arrival of snow has a different effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others it is a catastrophe or even a wonder. There are countries between these two extremes that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one such country, for which the arrival of snow quite simply creates problems. Within hours of the first snowfall, however light, roads are blocked, trains and buses stop in the middle of traffic. Normal communications are affected as well, telephone calls become difficult and the post immediately takes more time than usual. Almost within hours, there are also shortages -- bread, vegetables and other things -- not because all these things can no longer be produced or sent to shops, but mainly because people are frightened, and go out to store up these commodities , "just for fear that something bad should happen." Why then does snow have this effect? After all, the Swiss, Austrians and Canadians don't have such problems. It is simply because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow ploughs and machines to spread salt. The reason why a country like Britain does not buy some ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education or helping the old. Question: According to the writer, Britain is a country _ . Answer:
****
A: which is not well prepared for snow
