             steering wheel.
      c.     Make the driver exert more effort when moving the
             steering wheel.
11.   The set of mechanisms that make up the steering system have
      the mission of:
      a.     Align the front wheels so that the vehicle takes the trajectory.

12.   The mission of the suspension system of a car, truck, or bus is:
      a.     Absorb the vehicle's energy to increase speed.
      b.     Absorb the irregularities of the terrain over which one travels to
             increase the comfort and control of the vehicle.
             Absorb more fuel and improve the engine power.
13.   The purpose of the braking system is:
      a.     Allow the vehicle to stop at a greater distance.
      b.     Allow the driver to safely stop the vehicle as soon as possible.
             distance.
      c.     Allow the driver to drive the vehicle at a higher speed.
