What is the purpose of a vehicle's tire pressure monitoring system (TPMS)?

  1. To monitor and alert the driver about tire pressure levels

  2. To improve the vehicle's fuel efficiency

  3. To provide traction and control while driving on different terrains

  4. To reduce noise and vibration from the wheels


Correct Option: A
Explanation:

The TPMS monitors tire pressure levels and alerts the driver if any tire is underinflated or overinflated, ensuring safe and optimal tire performance.

What is the role of a vehicle's differential?

  1. To distribute power from the engine to the wheels

  2. To allow the wheels to rotate at different speeds when turning

  3. To provide traction and control while driving on different terrains

  4. To reduce noise and vibration from the drivetrain


Correct Option: B
Explanation:

The differential allows the wheels on the same axle to rotate at different speeds, enabling the vehicle to turn smoothly without causing tire wear or damage.

What is the purpose of a vehicle's catalytic converter?

  1. To reduce harmful pollutants in the vehicle's exhaust gases

  2. To improve the vehicle's fuel efficiency

  3. To provide traction and control while driving on different terrains

  4. To reduce noise and vibration from the engine


Correct Option: A
Explanation:

The catalytic converter is designed to reduce harmful pollutants, such as carbon monoxide and nitrogen oxides, in the vehicle's exhaust gases before they are released into the atmosphere.

What is the role of a vehicle's oxygen sensor?

  1. To monitor and adjust the air-fuel ratio in the engine
