1. Supports the roof
   Supports electrical wires
2. Allows you to hang art on it
   All of these

As you'd probably expect, a load-bearing wall holds up the roof. A wall doesn't need to be load-bearing to support art or a flat-screen TV.

1. Angle
   Density
2. Pitch
   Yaw

Though "angle" also sounds right, the correct term for this is "pitch." Among other things, a roof's pitch allows it to shed snow that might otherwise accumulate and put strain on it.

1. True
2. False

Carpenters also make furniture, as well as boats. Someone who makes a boat from wood in a traditional way is called a "shipwright."

1. Barn-raising
   Framing
2. Lifting
   Establishing

The basic wood skeleton of a house is its "frame." Framing was a big part of old-fashioned "barn raising," but that's actually a New England term for a community effort, putting up most of a new barn in a single day.

1. Abes
   Lays
2. Joists
   Studs

You're probably familiar with the term even you've done even a small amount of home decorating. Finding the studs in walls allows you to hang heavier pieces of art or a rack to keep your bike indoors.

1. Cross-cutting
   Marking
2. Shearing
   Very difficult

What exactly is "grain?" Funny you should ask ...

1. The darker knots in wood
   The denseness of the wood's molecules
2. The way the wood cells grew when the tree was alive
   Corn, barley, rye and such

Wood, like meat, has "grain," a result of the natural way the tree (or animal muscle) grew. Butchers, like carpenters, either cut with or against the grain.

1. Marking
   Obfuscating
2. Ripping
   There is no other term for it

Sounds violent, but this is the common term for cutting with the grain. Experienced carpenters know when to cross-cut and when to rip.

1. In a bathroom
   Between the wall and the ceiling
2. Above a door frame
   In a wooden door

Crown molding is ornamental woodwork between the top of a wall and the ceiling. Why can't the wall and ceiling just, you know, meet? We're not sure!

1. Band saws
   Miter saws
2. Plumb bobs
   Screwdrivers

This isn't just something that carpenters would know. The difference between a flat and a Phillips screwdriver is one of the first things people learn when they're learning about home repair.

1. The material of the blade: One is much stronger than the other.
   The shape of the tip: one is straight-across, while the other is cross-hatched.
2. The shape of the tip: One is straight-across and the other is hexagonal.
   One has a small motor and the other doesn't.

A Phillips screwdriver is meant to fit into a plus-sign-shaped notch on the screwhead. If the notch is narrow and straight across, you need a flat screwdriver.

1. Eco-friendly
   Expensive
2. Newly cut
   Of a rare type

Green lumber usually needs to be air-dried or kiln-dried before use. Working immediately with green lumber is unwise.

1. A band saw
   A drill
2. A Geiger counter
   A spirit level

A Geiger counter detects levels of dangerous radiation, named for Hans Geiger. If you're a carpenter and you need this tool, ask for a raise -- you're working under dangerous conditions!

1. Branches
   Joists
2. Chords
   Hypotenuses

You hear the word "joist" less often than stud. This is probably because it's rarer to mount things on joists than on studs.

1. Screws are smaller.
   Screws are larger.
2. Screws can be made of wood.
   Screws need no nut.

Bolts require nuts on the other side of the building material to be correctly fastened. Screws embed themselves directly in the material, and do not require a nut; in fact, they usually don't emerge from the other side of the wood.

1. 5 inches
   One foot
2. 16 inches
   Two feet

This reminds us of our favorite parody of ghost-hunting shows and the tech they use. In it, a ghost hunter turns a stud seeker into a "spectre detector" and is shocked to find there's a spirit "every 16 inches!" His partner sighs sadly and says, "There usually are."

1. Two
   Three
2. Four

Doors between rooms tend to be lighter than ones between the building and the outdoors. That's why interior doors need only two hinges, usually, while exterior doors commonly have three.

1. Any horizontal surface
   Any surface that's been sanded smooth
2. A gauge for determining smoothness
   A gauge for determining pitch

"Plane" is a broad term in carpentry, and related to the same term in geometry. Instruments used for determining whether a plane is level are called, not surprisingly, "levels."

1. Interior carpentry
   Finish carpentry
2. Trim carpentry
   Either "finish" or "trim"

It's not interior carpentry, because it's also done on the outside of the house. Essentially, this kind of work is the opposite of "framing," which is vital but hides under the plaster and drywall.

1. The baluster
   The banister
2. The landing
   The riser

The other terms are also the names of staircase parts. But "banister" is probably the best-known one, because of the joy kids take in "sliding down the banister."

1. Creating an angle on the edge of a piece of wood
   Putting stone or cement under a sill plate
2. Restoring serration to a dull saw
   Staining wood with natural materials

Beveling can be ornamental; you'll see it in crown molding, for example. It can also soften the edge of wood that people might come into contact with often -- like the edge of a dining table.

1. A basement
   A door frame
2. A roof
   Old Hollywood

A gable is a triangular section of roof. You'll see smaller gables jutting out from the roof of a house with an attic -- they provide extra head space. This is especially useful when the attic is used as living space, like a bedroom.

1. An air level
   A hydro-level
2. A spirit level
   A Wright level

The "spirit" is the fluid inside. When the bubble of trapped air is completely in the center of the tube, the surface the level is resting on isn't slanted.

1. Drill
   Hammer
2. Plumb bob
   C-clamp

The term "bore" refers to the diameter of the drill bit, and the size of the hole it makes. You hear the same term in the engineering of tunnels.

1. The floor
   The doors
2. The staircase
   The walls

The riser is the vertical part of the step. The tread is the horizontal part, on which the foot lands. The "going" refers to the distance in feet the staircase covers from the first step to the top landing. (It helps to visualize this as a line drawn along the bottom of the staircase.)

1. Dovetail joint
   Eave
2. Miter joint
   Prefabrication

A miter joint connects two angled pieces of wood. In an ecclesiastical setting, a miter is a bishop's hat.

1. Eldritch
   Gambrel
2. Ichor
   Antiquarian

Gambrel roofs are common to New England, and appear with clockwork regularity in the work of Rhode-Island-born horror writer H.P. Lovecraft. (Bonus points if you recognized the other words as three of Lovecraft's favorites as well!)

1. True
2. False

Generally speaking, a "softwood" comes from a conifer tree, like a pine. Hardwoods come from deciduous trees like oak. Within those categories, there is a varying degree of actual hardness.

1. The chuck
   The collar
2. The join
   The mouth

We're not sure why this needed a specialized term, but there it is. Don't mark yourself as a novice by saying you inserted the drill bit "into the drill." Amateur!

1. Ground plate
   Sill plate
2. Sole plate
   Any of these

This important part of the frame has several names. "Midnight sill" is another that you might hear.

1. An exam in architecture school
   Decorative woodwork around a door frame.
2. Extra support for the sill plate
   The arms that hold up rain gutters

Architraves are molding that hides where the door frame meets the wall. Seriously, what's with builders not wanting people to see where surfaces join?

1. Biscuit
   Huckleberry
2. Onion
   Slice of pie

A "biscuit" is an oval disk of wood. It has several purposes in woodwork. Putting gravy on this sort of biscuit is not recommended, and you'd be wasting jam on it, as well.

1. Keeping different weights of nails apart
   Keeping nails from bending during hammering
2. Sinking a nailhead a bit lower than the wood's surface
   Manicures

When nailheads are lower than the surface of the wood, things look nicer. But it's a pain if you're a homeowner trying to remove a nail with a simple claw hammer.

1. The grit of sandpaper
   How pieces of wood fit together
2. The decorations on a roofline
   They are slang terms for master, journeyman and apprentice

You've probably heard the term "flush" for pieces of any material that fit perfectly together. Rarer are "proud" and "shy"; they are terms for the piece that sticks up and the piece that's lower down, respectively.

1. Canada
   Italy
2. Poland
   Sweden

IKEA is actually the enemy of carpenters everywhere, what with their meticulously assembled furniture kits. However, thanks to the complexity of the directions to assemble said kits, a lot of carpenters have lucrative side gigs assembling IKEA furniture!
