Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to

each of the questions.

Today's cars are smaller, safer, cleaner, and more economical than their predecessors, but the

car of the future will be far more pollution-free than those on the road today. Several new types of

automobile engines have already been developed that run on alternative sources of power, such as

electricity, compressed natural gas, methanol, steam, hydrogen, and propane. Electricity, however,

is the only zero-emission option presently available.

Although electric vehicles will not be truly practical until a powerful, compact battery or other

dependable source of current is available, transport experts foresee a new assortment of electric

vehicles entering everyday life: shorter-range commuter electric cars, three-wheeled neighborhood

cars, electric delivery vans, bikes and trolleys.

As automakers work to develop practical electrical vehicles, urban planners and utility engineers

are focusing on infrastructure systems to support and make the best use of the new cars. Public

charging facilities will need to be as common as today's gas stations. Public parking spots on the

street or in commercial lots will need to be equipped with devices that allow drivers to charge their

batteries while they stop, dine, or attend a concert. To encourage the use of electric vehicles, the

most convenient parking in transportation centers might be reserved for electric cars.

Planners foresee electric shuttle buses, trains, buses and neighborhood vehicles all meeting at

transit centers that would have facilities for charging and renting. Commuters will be able to rent a

variety of electric cars to suit their needs: light trucks, one-person three-wheelers, small cars, or

electric/gasoline hybrid cars for longer trips, which will no doubt take place on automated freeways

capable of handling five times the number of vehicles that can be carried by freeway today.
