Read the following article and select the best answer. Article: City traffic is a great problem. More cars are produced every year and the streets are getting more and more crowded. So during "rush hours", when people are going to or from their work, traffic is brought to a standstill. It has been suggested that commuters--the people who travel to work every day from outside the city--should share their cars and give each other lifts. So each car would carry four or five people instead of only one. It is an excellent idea., however, so far nobody has been able to think of a way to make people do so. To discourage motorists from leaving their cars in the streets all day, parking meters are used. When you park at a meter, you must put a coin in the slot . This pays for a certain amount of time. The meter records this and it shows when the time that you have paid for is finished. If the car is still there then, you have to pay a fine. Traffic wardens look after the meters. They walk around the streets and check that every meter shows that money has been paid for the car parked there. If a meter shows 'TIME EXPIRED', the motorist who has left his car there is fined. Of course, the traffic warden can not wait for the owner of the car to return. He carries many printed forms, and on one of these he writes down all the details, such as the number of the car, where it is parked, how much the driver must pay and where he must send the money. He leaves this form on the car, where the driver will be able to see it easily; he usually pushes it under one of the windscreen wipers so that it will not be blown away. And in case it rains before the motorist returns, the form is put in a little plastic envelope to protect it. When the driver comes back, he gets an unpleasant surprise, but it is his own fault for leaving his car too long at parking meter. Question: The passage implies_. - cars with more people are needed to solve traffic problems - commuters should go to work by bike - cars with fewer people are needed to solve traffic problems - we should reduce car production
cars with more people are needed to solve traffic problems

Q: 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: Why is salt attacked by doctors and politicians? - It's unnecessary. - It does no good to human health. - It is hated by most people. - It will always lead to heart disease and circulatory disorders.
A: It does no good to human health.
