1. Cuts and skinned knuckles
   Petrochemical exposure
2. Sore joints
   All of these

If you're allergic to petroleum-based products or don't want scrapes on your knuckles, this might not be the job for you. Also, mechanics like to say "It helps if your knees bend backward" because you will have to get in a lot of awkward positions.

1. The increase in onboard computers
   The high cost of tools
2. The increase in fuel-injection systems
   Increasingly car-savvy customers

Fuel injection has been around since the 80s, and most mechanics are familiar with it; the other two issues probably haven't changed much in the past forty or fifty years, either. More than anything, it's sophisticated onboard computers that make things hard for mechanics trained before the turn of the millennium.

1. Bugatti
   Idiosyncratic
2. Slushbox
   Standard

"Standard" and "manual" transmission are the same thing. "Slushbox" is a mocking term for an automatic transmission.

1. On a V8 truck
   On a Korean import
2. On a Prius
   On a vintage car

The humble fan belt used to connect the fan to the alternator. Nowadays, most cars have a more versatile "drive belt."

1. A 1997 Honda Accord
   A 1967 VW Beetle
2. A Tesla Model S
   A 2005 Toyota Prius

Both the Tesla and the Prius are "alternative energy" cars and would present some special challenges for a mechanic not trained in that area. But the Tesla is all-electric, expensive and rare -- three issues the everyday Prius does not share.

1. Rebuilding the carburetor
   Checking the timing
2. Replacing brake pads
   These are all easy jobs

Fuel injection has replaced carburetion on most modern cars. So if you talk to someone who's rebuilding a carburetor, you know that he or she owns something at least semi-vintage.

1. It improves handling
   It is more fuel-efficient
2. It creates cleaner emissions
   Both #2 and #3

Fuel injection and carburetion are both about how the car's fuel is mixed with air before ignition. It doesn't affect handling.

1. Combustion
   Cooling
2. Electrical
   Suspension

When the fuel-air mixture ignites too early, knocking or pinging can occur. The wrong octane of fuel can cause this, but more often it's a timing problem.

1. Compression
   Consumption
2. Power
   Exhaust

The four strokes are intake, compression, ignition (or "power") and exhaust. This is the essential "heartbeat" of the engine, that creates power to distribute to the powertrain.

1. True
2. False

The car's fuse box is usually found near or under the dashboard in the passenger cabin. A blown fuse to the fuel pump will cause a car to stop dead in the water.

1. The battery
   The camshaft
2. A coil
   The radiator

Like any other battery, a car's battery has a positive and negative terminal. You probably knew this from giving your car, or someone else's, a jump start.

1. Apparent leak sighting
   Anti-lube system
2. Anti-lock brakes
   A better solution

Anti-lock brakes began replacing drum brakes in the late 20th century. A key difference is that you shouldn't pump anti-lock brakes in a skid -- the system does it for you.

1. Flushing transmission fluid
   Flushing brake fluid
2. Replacing spark plugs
   Rebuilding a carburetor

Spark plugs are famous for settling into the engine block and getting comfortable -- so comfortable that after their working life is over, they can be wickedly hard to pull out and replace. Keep your head: Yanking furiously at them can cause them to snap off, and then you're REALLY in trouble.

1. Drive belt
   Helper belt
2. Multi-accessory belt
   Both #1 and #3

This belt gets its name(s) from the way it transmits power to several "accessories" in the engine, like the alternator, the fan, and the water pump. *Come to think of it, these don't sound like accessories at all -- they are pretty important!

1. In the exhaust system
   In the electrical system
2. In the radiator
   On a shop floor

A creeper is a rolling backboard that allows a technician to go comfortably under the car and move around down there. *Nowadays, it also means a creepy person, but that's a subject for an internet-lingo quiz.

1. ACE
   ASE
2. OBE
   LMFT

ASE certification is given out by the National Institute for Automotive Service Excellence. The test is taken by, and the certification awarded to, an individual, not a shop overall.

1. Air filter
   Fuel filter
2. Oil filter
   Tailpipe filter

Although there are several devices in the car that limit emissions, there isn't actually a "tailpipe filter."

1. Brakes
   Catalytic converter
2. Spark plugs
   Wheels

Alignment is done by tire shops, usually and not auto-repair shops. But a mechanic might well be called on to diagnose an alignment problem.

1. A block heater
   Jack stands
2. Extra transmission fluid
   Drum brakes

A block heater keeps the engine warm in very cold temperatures, to make starting the car easier. *Canadians, you knew this one right away, eh?

1. Braking
   Cooling
2. Starter
   Steering

Brake pads and brake shoes are essential parts of the system. So are brake lines and the fluid that fills them -- as you'll know if you read vintage mystery novels; brake lines are always being cut.

1. The clutch
   The choke
2. The axle
   The transaxle

Both manual and automatic transmission cars have a clutch. It's in manual cars, though, that you put in the clutch yourself, before changing gears.

1. The crankshaft
   A coil
2. The fuel tank
   A spark plug

While all of these have a role to play in making the car go, only the crankshaft is part of the powertrain. It is turned by power from the pistons, just after the combustion process.

1. An Allen key
   A ball-peen hammer
2. That's not my job!
   Both #2 and #3

A ball-peen hammer is sometimes used for correcting dents in a car's body. However, bodywork and mechanical work are very different things. Most mechanics don't do bodywork.

1. The brakes
   The firewall
2. The fuel-injection system
   The starter motor

The firewall is pretty much what it sounds like -- an insulated wall that protects the driver from heat, flames or fumes in an accident. Without moving parts, there's not much that can go wrong, therefore little need for repair.

1. The clutch pedal
   The driveshaft
2. The flywheel
   Spark plugs

If the gap between the two electrodes of a spark plug is too wide, that plug won't fire efficiently. The feeler gauge will tell you if this is the case.

1. Diesel
   Domestic
2. Imported
   Less than 87 octane

It's hard to imagine anything living in the medium of fuel, but this is a problem with diesel fuel. Car parts stores sell biocides that combat the growth of fungus.

1. The carburetor
   The ignition wiring
2. The flywheel
   The rear differential

As the name indicates, the idle speed screw affects the number of rpms at which the engine idles. It's fairly easy to adjust -- but you'll only have this if you have an older vehicle, therefore a carburetor.

1. Enhancing
   Carbonating
2. Oxygenating
   Turbocharging

Turbocharging uses a fan, or turbine, to force more air into the cylinder and get a bigger bang out. Because the fan itself is powered by the flow of exhaust gases from the cylinder, the process is very efficient -- it's using the car's own waste product, exhaust, to create more power.

1. It uses a pump, not a fan
   It's less efficient
2. Superchargers are found on diesel engines
   Both #1 and #2

Supercharging is generally found on luxury sports cars, whose owners tend to worry less about fuel efficiency. It doesn't use the flow of exhaust gases to power a fan, so supercharging doesn't efficiently support itself in the way turbocharging does.

1. Burnt toast
   Exhaust fumes
2. A perfume-like smell
   A rotten-egg smell

The scent of exhaust inside the car suggests that a loose exhaust pipe is letting fumes in through the floorboards, which is very dangerous for the people inside. One of the stars of MTV's "Buckwild" died, along with two other men, when mud covered the tailpipe of their Bronco and exhaust backed up into the vehicle.

1. Chilton
   Harcourt Brace Jovanovich
2. Knopf
   Liebermann

Another company now publishes these manuals, in place of the now defunct Chilton. Fun fact: On the fiction side, Chilton Publishing published "Dune," the landmark science fiction novel.

1. About 15 minutes
   About 30 minutes
2. More than an hour
   Hey, that's a trick question!

The Mini Cooper has no rear differential. There's even a joke about this in the original movie "The Italian Job," in which one of the gang members tells Michael Caine, "Rozzer's having trouble with his rear differential."

1. Moonlight
   Two-bit
2. Roadshow
   Shade-tree

This term probably got started from the idea that casual mechanics, who did have shops, worked in the shade of an overhanging tree to stay out of the heat. The term was revived by the TV show "Shadetree Mechanic," which ran from 1992 to 2000 on what is now Spike TV.

1. Women don't like getting dirty
   They are not allowed to take certification exams
2. They can't do the heavy lifting involved
   There are female mechanics

Women are rare, but not nonexistent, in the field. But women seem to have made more inroads into engineering or computer programming -- also fairly male-dominated fields -- than car repair, perhaps because the wages are more desirable.

1. Car hygienist
   Automotive specialist
2. Automotive technician
   Car & truck diagnostician

The term "technician" isn't just a way of making the job sound harder than it is. Engine work really has gotten a lot more technical since the day of the '57 Chevy. A mechanic today, especially if he's passed a certification exam, has earned that term!
