A hybrid vehicle is a vehicle which uses two or more kinds of propulsion. Most hybrid vehicles use a conventional gasoline engine as well as an electric motor to provide power to the vehicle. These are usually called hybrid-electric-vehicles, or HEVs. Hybrids use two types of propulsion in order to use gasoline more efficiently than conventional vehicles do. Most hybrid vehicles use the gasoline engine as a generator which sends power to the electric motor. The electric motor then powers the car. In conventional vehicles, the gasoline engine powers the vehicle directly. Since the main purpose of using a hybrid system is to efficiently use resources, most hybrid vehicles also use other efficient systems. Most hybrid vehicles have regenerative braking systems. In conventional vehicles, the gasoline engine powers the brakes, and the energy used in braking is lost. In regenerative braking systems, the energy lost in braking is sent back into the electrical battery for use in powering the vehicle. Some hybrid vehicles use periodic engine shutoff as a gas-saving feature. When the vehicle is put back in gear, the engine comes back on. Some hybrids use tyres made of a stiff material which rolls easily and prevents drag on the vehicle. Since hybrid vehicles use less gasoline than conventional vehicles, they put fewer emissions into atmosphere than conventional vehicles, they put fewer emissions into the atmosphere than conventional vehicles do. As hybrids have become more popular, conventional vehicles are being used less, and the level of emissions being put into the air is decreasing. Hybrid vehicles are an example of an energy – efficient technology that is good for both consumers and the environment.
Two kinds of propelling forces used by hybrid vehicles are
(a)	electric motor and power.	(b)	electric engine and generator.
(c)	gasoline engine and electric motor.	(d)	electrical battery and gasoline.
The difference between hybrid and conventional vehicle is that
(a)	hybrids are heavier as compared to conventional ones.	(b)	hybrids do not use electric motors while conventional ones do.
(c)	hybrids use gas while conventional vehicles use petrol	(d)	hybrids use two types of propulsions while conventional rely on one.
Why do HEVs use two types of propulsions?
(a)	To go faster.	(b)	To use gasoline efficiently.
(c)	To provide a comfortable ride.	(d)	To become environmentally friendly.
Regenerative most closely means
(a)	restorative	(b)	electric
(c)	gasoline	(d)	powerful
In the context of the passage which of the following best articulates how the author regards the topic?
(a)	Conventional vehicles may be more powerful than hybrid vehicles but hybrid vehicles are more socially responsible.	(b)	Since hybrid vehicles use less gasoline and put fewer emissions into the atmosphere, they are better for the environment.
(c)	Hybrid vehicles are less expensive, so they are a smarter buy than conventional vehicles.	(d)	Conventional vehicles are faster but hybrid vehicles are better for the environment.
