In London, there has always been a main problem. In order to solve this problem, the government has decided to have a bike revolution(革命). It has decided to provide 6,000 bikes for the people to rent. The government encourages local people to ride bikes in order to solve the traffic problem. More than 12,000 people have agreed to the idea. Some of them ask for more than one key. Although there are not enough bikes, an official(官员) from the government said that they would find some ways to deal with such a shortage. Local people can get these bikes at special docking stations（停靠站）.There are about 315 docking stations across the city. About 12,450 keys have already been handed out to the local people, but only 6,000 keys can be used now. Let’s see the cost you need to pay. One key costs ￡3, and the cost of using the bike is ￡1 for an hour. The cost per hour increases as the hours increase, so it will cost ￡50 if you rent the bike for 24 hours. The official from the government said they also needed to face a lot of problems, for example, some bikes may be lost. But they said they would try their best to solve all the problems to make sure the success of the program. 小题1:In London, the government has decided to provide bikes for local people to rent in order to solve ______________.
