Questions 1 to 5 are based on the following passage. Transportation is a problem in Nigeria, as in many African countries. The public transportation system is limited and costly, the roads are poor, and few people own cars. But some people own motorcycles, and so with their motorcycles the Nigerians have invented a new kind of taxi. The name for this new kind of motorcycle taxi is okada. The first okada riders were the owners of motorcycles who stopped on the country roads to give people a ride. Then the motorcycle owners realized that they could make money in this way. They began to look for passengers and charge fares for the rides. Soon the okada system became a part of Nigeria life. Though the okada has solved some transportation problems, it has created others. The biggest problem is that the government does not regulate the system. For instance, there are no rules about who can be an okada rider. The riders do not have to pass any special test or get a special license, so many of them are poorly educated and do not know the rules of the road. Another problem is that the okada system is now big business in Nigeria. That means more people — mostly government workers and businessmen — are trying to get some of the profits. They buy motorcycles and rent them out at high prices to okada riders. The riders must then work hard in order to pay the rent and also earn a living for their families. That is why okada riders often drive fast and dangerously. Yet another problem is the conflict that has developed between okada riders and bus drivers. Like the okada riders, the bus drivers’ income depends on the number of passengers they carry. Thus, they are in direct competition with the okada riders. This competition has at times become a real battle. Okada riders and passengers have been injured and killed by buses at bus stops, while the okada riders have set fire to several buses. According to a local newspaper, many Nigerians are angry with this situation. They believe that the government should take control of the okada system and make sure that okada riders know how to drive safely. They also want the government to find a way to resolve the conflict between the okada riders and the bus drivers. Nigerian people are expecting the government to _________.
