read the passage \how hybrid cars work\ and then answer numbers 7 through 10.
how hybrid cars work
with nearly 300 million automobiles on the road, the united states consumes a staggering amount of gasoline every day. in response, scientists and car companies have teamed together to lessen the strain on earths natural resources and create a vehicle that uses alternative forms of energy. the result is the hybrid car. a hybrid is a vehicle that uses both a gasoline engine and an electric motor.
how do gas and electric cars go?
before we discuss how hybrid cars work, lets first examine the difference between gas - powered cars and electric cars. gas - powered cars have a fuel tank that supplies gasoline to an engine. the engine turns a transmission. the transmission uses the engines power to turn the wheels on a car. in contrast, electric cars are powered by a set of batteries. electric power from the batteries moves the electric motor that turns the transmission. then the transmission turns the wheels as usual.
how does this diagram (text feature) better help you understand the text?

Explanation:

1. Summary of the paragraph: In the US, with a large number of automobiles consuming much gasoline daily, scientists and car - companies collaborated to ease the strain on natural resources and created hybrid cars which use both a gasoline engine and an electric motor.
2. Summary of the section: Before discussing hybrid cars, it first explains the difference between gas - powered and electric cars. Gas - powered cars have a fuel tank for gasoline to power the engine which turns the transmission. Electric cars are powered by batteries which move an electric motor to turn the transmission.
3. Explanation of the diagram's help: The diagram visually represents the components (fuel tank, gasoline engine, electric motor, battery, generator, transmission, and wheels) and their connections in a hybrid car, making it easier to understand how the different parts work together as described in the text.

Answer:

1. In the US, due to high gasoline consumption by many cars, hybrid cars using both gas and electric power were developed.
2. Gas - powered cars use gasoline from a tank to power the engine and transmission, while electric cars use battery - powered electric motors for the transmission.
3. The diagram visually shows hybrid car components and their connections, aiding text comprehension.
