Neither     答案：C  A bicycle sharing system, or bike share scheme, is a service in which bicycles are made available for shared use to individuals who do not own them.Bicycle sharing systems can be divided into two general categories: "Community Bike programs" organized mostly by local community groups or non-profit organizations; and "Smart Bike programs" implemented by government agencies, sometimes in a public-private partnership.   Bikes are tracked with Spark Mobility,software that can keep a permanent record of registered bike riders individuals who damage or do not return bikes can be held responsible. Riders must register with Spark Mobility,which also shows users how many bikes are available at a given time.   The central concept of these systems is to provider affordable access to bicycles for short-distance trips in an urban area as an alternative to motorized public transportation or private vehicles, so as to reduce traffic jams, noises, and air pollution. Bicycle sharing systems have also been used as a way to solve the "last mile" problem and connect users to public transportation networks.   However, public bike sharing programs also have disadvantages,including loss from theft,lack of parking or storage,and the cost of repairs. What's more,by limiting the number of places where bicycles can be rented or returned, the service itself becomes a form of public transportation, and is therefore less convenient than a privately-owned bicycle.Government-run bicycle sharing programs can also prove costly to the public unless supported by commercial interests, typically in the form of advertising on stations or the bicycles themselves.   By May 2011,there were around 136 bike sharing programs in 165 cities around the world, with about 237,000 bicycles. Started in 2008, the Hangzhou Public Bicycle program in China is the largest bicycle sharing system in the world, with around 61,000 bicycles and over 2,400 stations. 72.What do we know about bicycle sharing systems?
