Read the following article and select the best answer. Article: Do you have bright ideas? Ideas or inventions that change society or, at least, make life easier for somebody? Perhaps we all do sometimes, but we don't often make the idea a reality. Recently, in Britain, there was a competition called British Designers for Tomorrow. The competition encourages young people to carry out their bright ideas. There were two groups in the contest: Group One was for schoolchildren under 16; Group Two was for schoolchildren over 16, and there were eleven prize-winners altogether. Neil Hunt, one of the prize-winners, was called "Sunshine Superman". It's important when people study the weather to be able to record sunshine accurately. We need to know how many hours of sunshine we have and how strong it is. Most sunshine recorders only record direct sunlight. Neil's is more accurate and this is very important for research into the way of using solar power. You can do so much with animated cartoon. Look at Simon West's idea for animated road signs. He uses pictures which appear to move as you go nearer to or farther from them. This isn't a new idea. But it is new to use these pictures on road signs. "We found that people were more likely to see moving signs," said Simon. So now, you can really see rocks falling, trains moving, horses running or a car falling over the edge of a cliff. Quite a warning! The ideas in the competition were so inventive that we are surprised that British industry doesn't ask more schoolchildren for suggestions. Perhaps this will be the start of "pupil power!" Question: What's the use of Simon West's animated road signs? - To add to the beauty of a city. - To warn people on the roads of the danger ahead. - To help make a car trip more exciting. - To warn people to be careful while working.
To warn people to be careful while working.

Read the following article and select the best answer. Article: The year is 2094. It has been announced that a comet is heading towards the earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the earth. On 17 July, a piece of 4 kilometers wide comet enters the Earth's atmosphere with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the seabed. Huge waves are created and spread outwards form the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned . Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes ash set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive. Could it really happen? In fact, it has already happened more than once in the history of the earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end? Question: What is mainly described in the passage? - A historic discovery. - An event in imagination. - A research on space. - A scientific adventure.
(Answer)
An event in imagination.

Question: Read the following article and select the best answer. Article: Spending beyond one's means is becoming a national problem for Americans.Borrowing has become so easy that it takes great willpower for people to refuse it."I received a number of gold MasterCard and gold Visa card offers in the mail during the past two months,"said one computer engineer at AT &T Bell Laboratories in Chicago."I got three of them in one day last week." Lenders are providing easy credit for borrowers.Many banks now offer every borrower a great variety of credit,a service once offered almost only to big companies.Norwest Bank Minneapolis offers lending programs for cars and boats that can cut monthly payments nearly m half .Carmakers,too,are lengthening easier terms.Ford Motor Credit states that 45 % of its recent lendings has been for sixty months,rather than the sixty-six-month period that was usual before. The total consumer debt in the United States rose 73 percent between 1974 and 1984,as the debt for each man,woman,and child increased from $10,264 to $26,566.Huge debt now is present in our economy at all levels.As a nation,we are more than $7 trillion in debt,and the total keeps increasing astonishingly. As we have over borrowed,so have we overspent.In late 986,the share of after-tax income that Americans saved sank below 2 percent for a short time,less than half the figure at which we saved only 10 years ago.Americans now are buying from foreigners between about $50 and $100 billion more Mercedes and Toyotas, Paris fashions,and tours to Europe than the Boeing 747s, agriculture machinery , or Kansas wheat that the foreigners bought from America. The country could not produce and pay for all the things it wanted. To make a long story short, we Americans have serious problems in keeping down spending and keeping up personal savings.It is high time for us American people to learn the basics of long-term money management. Question: Which of the following points does the author wish to make? - America should sell more of its products abroad. - A healthy society has to learn to 1ive within its means. - People's income determines their money management. - Government should prevent people from over borrowing.
Answer:
A healthy society has to learn to 1ive within its means.
