Read the following article and select the best answer. Article: In recent years, there has been a steady attack on salt from the doctors: salt is bad for you--regardless of your health. Politicians also got aboard. "There is a direct relationship," US Congressman Neal Smith said, "between the amount of sodium a person consumes and heart disease, circulatory disorders, stroke and even early death." Frightening, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. "All these remarks and cry about salt is unnecessary," Dr. Dustan insists. "For most of us it probably does not make much difference how much salt we eat." Dustan's most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet, or later when salt was reintroduced. Of the hypertensive patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced. "An adequate to somewhat excessive salt intake has probably saved many more lives than it has cost in the general population," said Dr. John H Laragh. "So an opinion that the whole population should avoid salt makes no sense." Medical experts agree that everyone should practice reasonable "moderation" in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing, preparation or at the table. "Na is not your enemy," says Comek's Dr. Laragh. "Salt is the No.1 natural component of all human tissue, and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up." Question: What is the experts' advice for average people on salt consumption? - They should increase salt intake through sodium pills. - They should avoid salt as often as possible. - They should consume 1/2 to 1/3 teaspoons of salt a day. - They needn't care about how much salt they consume.
They should consume 1/2 to 1/3 teaspoons of salt a day.

Read the following article and select the best answer. Article: "Slow City" -- a recently launched project focused on preserving the traditional quality of life enjoyed in some of Italy's smaller cities and towns. The project was born from the idea of the "Slow Food" movement -- started in Italy in the 1980s -- which promotes leisurely eating and the growing of local, healthy products to fight against the American fast-food style. "The American urban model has invaded our cities, making Italian towns look the same. We want to stop this kind of globalization," says Paolo Saturnini, an Italian mayor. The "Slow City" project plans to emphasize the rich, cultural, culinary and artistic local traditions of each community. Walking areas will be enlarged and squares and parks will be made greener with more plants. Car alarms and other noise that disturbs the peace will be banned, and ugly TV aerials , advertising posters, and signs will be taken down. City councils will also insist on the use of recycling and renewable energy sources, and will also introduce ecological transport systems. Parking will be made stress-free by creating more public parking areas, and easily accessible walkways and bike lanes will cross the city. But in the "Slow City" way, all improvements will probably come about slowly. Thirty-two Italian city councils, which joined the "Slow City" program, have decided to take further steps in this direction by increasing the numbers of traditional family-style eating establishments, reducing noise pollution, and concentrating on making their towns friendlier for people to live in. Organic local produce will be promoted in all restaurants and genetically modified foods will be banned. "We can't stop large, fast-food chains from coming here, but we hope that people who come to our towns will not want to eat exactly the same hamburger they can eat in Melbourne, London or Paris, but want something genuine and different," said Saturnini. Question: According to the passage, the "Slow City" project aims at _ . - preventing Italy from being affected by America - beautifying the environment of small Italian cities and towns - calling on Italians to enjoy stress-free life - protecting the traditional Italian lifestyle
protecting the traditional Italian lifestyle

*Question*
Read the following article and select the best answer. Article: A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". And the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us. The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature of between I and 4degC;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased. Question: If there were no greenhouse effect, _ . - all plants would not grow on our planet - soil would reduce the temperature by 30 degrees - man would breathe the cleaner air - people couldn't live in the earth
**Answer**
soil would reduce the temperature by 30 degrees
