Article: The Channel is the name given to the stretch of water which separates England and France. Ferries operate all year round to carry people across the Channel, and they are busy most of the year. January is the only quiet month nowadays. As well as summer holiday-makers, there are day trippers and coach traffic, not to mention lorries and other commercial vehicles. Some ferries carry cars and their passengers, while others also connect train passengers with the Continental rail network. The biggest hazard for the ferry is the wind. The crew listens to BBC weather reports four times a day. Or they sometimes get gale warnings from local radio station. Crossing the Channel by ferry is a bit like trying to cross Oxford Street on a busy afternoon, according to one ferryboat captain. The ferries from Folkstone and Dover to Calais and Boulogne have to cross the main flow of traffic. This consists of ships traveling through the Channel to and from Northern Europe. There may be four hundred ships making the journey at any one time, and they all pass through a "choke point" which is only fifteen miles (twenty-five kilometers) wide. The cross-channel ferries have to sail right through the middle of all this traffic.
Answer: what crossing the Channel by ferry is like

Article: Consumers are being confused and misled by the hodge-podge of environmental claims made by household products, according to a "green labeling" study published by Consumers International Friday. Among the report's more unacceptalbe findings - a German fertilizer described itself as "earthworm friendly"; a brand of flour said it was "non-polluting" and a British toilet paper claimed to be "environmentally friendlier". The study was written and researched by Britain's National Consumer Council (NCC) for lobby group Consumers International. It was funded by the German and Dutch governments and the European Commission. "While many good and useful claims are being made, it is clear that there is a long way to go in ensuring shoppers are adequately informed about the environmental impacts they buy," said Consumers International director, Anna Fielder. The 10-country study surveyed product packaging in Britain, Western Europe, Scandinavia and the United States. It found that products sold in Germany and the United Kingdom made the most environmental claims on average. The report focused on claims made by specific products, such as detergent , insect sprays and some garden products. It did not test claims, but compared them to labeling guidelines set by the International Standards Organization (ISO) in September, 1999. Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards. "Many products had specially designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing," said report researcher Philip Page. "Laundry detergents made the most number of claims with 158. Household cleaners were second with 145 separate claims, while paints were third on our list with 73. The high numbers show how confusing it must be for consumers to sort the true from the misleading," he said. The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as "environmentally friendly" and "non-polluting" cannot be verified. "What we are now pushing for is to have multinational corporations meet the standards set by the ISO," said Page.
Answer: the claims made by products are often unclear and deceiving
answer:
According to the passage, the NCC found it unacceptable that _ .

question:
Article: American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface. Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace. The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer liquid. When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic. The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.
