Question

[Lê Quỳnh Anh]

Read the following passage and then choose the best answer for each question by circling the corresponding letter A, B, C or D from 2 to 9.

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 than 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. 

It can be inferred from the passage that 

A. many new types of electric engines have been developed 

B. the present electric engines are the best option as being practical 

C. electricity is the best alternative source of power as it is almost free of pollution 

D. the present cars are more economical than their future generation

Nó có thể được suy ra từ đoạn văn rằng

A. nhiều loại động cơ điện mới đã được phát triển

B. các động cơ điện hiện nay là lựa chọn tốt nhất vì nó thực tế

C. điện là nguồn năng lượng thay thế tốt nhất vì nó gần như không bị ô nhiễm

D. những chiếc xe hiện tại là kinh tế hơn so với thế hệ tương lai của chúng

Thông tin: Several new types of automobile engines have already been developed than run on alternative sources of power, such as electricity, compressed natural gas, methanol, steam, hydrogen, and propane.

Tạm dịch: Một số loại động cơ ô tô mới đã được phát triển hơn là chạy bằng các nguồn năng lượng thay thế, như điện, khí tự nhiên nén, metanol, hơi nước, hydro và propan.
