Sample Practice Test Questions

Word Knowledge
Turmoil most nearly means:
chaos
Extreme confusion, agitation.
Automotive Information

Which of the following is the correct order for the engine stroke cycle?

intake, compression, power, exhaust

The stroke cycle order is intake stroke, compression stroke, power stroke, exhaust stroke.

Word Knowledge
The jewel thief entered the mansion under the pretense of fixing a leaky faucet.
cover
False intention or purpose.
General Science

In the water cycle, infiltration is most closely related to:

water table

The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.

General Science

A subatomic particle found in the nucleus of an atom. It carries a positive electric charge. This desribes which of the following?

proton

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.

General Science

A major difference between sound waves and light waves is which of the following?

all of these are correct

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.

Math Knowledge
y = -2x - 2

The endpoints of this line segment are at (-2, 2) and (2, -6). What is the slope-intercept equation for this line?

y = -2x - 2

The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is -2. The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 2) and (2, -6) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (2.0)}{(2) - (-2)} \) = \( \frac{-8}{4} \)
m = -2

Plugging these values into the slope-intercept equation:

y = -2x - 2

General Science

The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed by the gradual depositing of small rocks?

sedimentary

The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.

Automotive Information

What's the name of the low-voltage winding in the ignition coil?

primary coil winding

The ignition coil is a high-voltage transformer made up of two coils of wire. The primary coil winding is the low-voltage winding and has relatively few turns of heavy wire. The secondary coil winding is the high-voltage winding that surrounds the primary and is made up of thousands of turns of fine wire. Current flows from the battery through the primary coil winding which creates a changing magnetic field inside the secondary coil. This induces a very high-voltage current in the secondary coil which it feeds to the distributor.

Word Knowledge
Prudent most nearly means:
judicious
Marked by wisdom, shrewd.
