Q: 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

Q: Article: From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a complicated and potentially dangerous game with its environment, discomfort or destruction. This is a difficult and unpleasant business and few animals would survive if they had to start from the beginning and learn about the world wholly by trial and error, for there are too many possible decisions which would prove fatal. So we find, in practice, that the game is always arranged in favor of the young animal in one way or another. Either the animal is protected during the early stages of its learning about the world around it, or the knowledge of which way to respond is built into its nervous system from the start. The fact that animals behave sensibly can be attributed partly to what we might call genetic learning, to distinguish it from individual learning that an animal does in the cause of its own life time. Genetic learning is learning by a species as a whole, and it is achieved by selection of those members of each generation that happen to behave in the right way. However, genetic learning depends upon a prediction that the future will more or less exactly resemble the past. The more variable individual experience is likely to be, the less efficient is genetic learning as a means of getting over the problems of the survival game. It is not surprising to find that very few species indeed depend wholly upon genetic learning. In the great majority of animals, behavior is a compound of individual experience added to the action patterns animals are born with.That is why animals can survive.
Answer: decisions made by animals may prove fatal

A: The survival game is considered complicated and potentially very dangerous because _ .

Q: Article: Modern festival-goers who worry about ending up with a dead mobile phone battery after days stuck in a muddy field with no electric plug power points may now have a solution----power boots . Mobile phone company European Telco Orange has introduced a phone charging prototype---- a set of thermoelectric gumboots or Wellington boots with a "power generation sole" that changes heat from the wearer's feet into electrical power to charge battery-powered hand-helds. The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. "In the sole of the Wellington boot there's a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge," Pain said. "That electrical charge we then pass through to a battery which you'll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone." These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made. But the prototype boot does have one _ . You have to walk for 12 hours in the boots to make one hour's worth of charge.
