1. If the shock absorbers are defective,
   1. the springs will wear out too soon.
   2. the front wheels will go out of alignment.
   3. the brakes will lock up too soon.
   4. the wheels will rebound excessively after the car hits a bump.
2. Some cylinder heads are made of aluminum because
   1. it is light and inexpensive.
   2. it is heavy and inexpensive.
   3. cast iron warps too easily.
   4. it is light and conducts heat well.
3. Disk brakes are sometimes used only on the front wheels because
   1. disk brakes are easier to steer.
   2. the front wheels provide most of the stopping force.
   3. disk brakes are cheaper to make than drum brakes.
   4. disk brakes are less likely to seize up than drum brakes.
4. In a 12-volt system, when the electric current is 12 volts, the battery is
   1. charging.
   2. discharging.
   3. neither charging nor discharging.
   4. I cannot tell. There is not enough information to answer the question.
5. In a hydraulic system, a 2-inch-diameter master cylinder drives a 1-inch-diameter wheel cylinder. If we move the piston 3 inches into the master cylinder,
   1. the force will be multiplied at the wheel cylinder.
   2. the force will be reduced at the wheel cylinder.
   3. the force will be the same at the wheel cylinder.
   4. nothing will happen. This hookup will not work because the slave cylinder needs to have a larger diameter than the master cylinder.
6. A higher viscosity rating is applied to oil that is
   1. thicker.
   2. thinner.
   3. less likely to freeze in winter.
   4. more likely to overheat.
7. If a car has a fuel injector, it will not have
   1. a regulator.
   2.  
   a carburetor.
   3. an Otto-cycle engine.
   4. a fuel filter.
8. When the brake shoes wear down too much, you are likely to see ___ in the drums.
   1. glazing
   2. scoring (gouges)
   3. hot spots
   4. rust
9. When you see blue smoke coming from the tailpipe, you should check the
   1. piston rings.
   2. intake valves.
   3. positive crankcase ventilation system.
   4. fuel system.
10. If a car suddenly stops responding to the starter and the headlights do not light, what would be the most likely problem?
    1. The battery terminals or cables are corroded.
    2. The battery has gone dead.
    3. The starter switch is bad.
    4. The starter motor has died.
11. If a manual transmission is in neutral,
    1. the wheels cannot turn.
    2. the engine can run without moving the car.
    3. the differential is locked up.
    4. the transmission cannot be shifted.
12. When you bolt a cylinder head into place, you should
    1. align the cylinders with the pistons.
    2. align the carburetor.
    3. check the main bearings.
    4. observe proper tightening torque.
13. If the oil light comes on while you are driving,
    1. drive home and check for problems.
    2. replace the oil within 1,000 miles.
    3. do not worry unless you see other evidence of trouble; the light is probably defective.
    4. as soon as it's safe, pull over to find the problem.
14. Which components are not found in a car with electronic ignition?
    1. Coil wire and distributor
    2. Coil and alternator
    3. Distributor and ECU
    4. ABS and ECU
15. If it's hard to shift gears in a car with manual transmission,
    1. add transmission oil.
    2. check the free play on the clutch.
    3. don't worry, the oil is probably cold.
    4. try starting in gear.
