Sample Practice Test Questions

General Science

I biome is made up of naturally occurring flora and fauna.  Fauna is which of the following?


A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).

Electronics Information

The conductivity of an element depends on how many electrons occupy which electron shell?


All electricity is the movement of electrons which are subatomic particles that orbit the nucleus of an atom. Electrons occupy various energy levels called shells and how well an element enables the flow of electrons depends on how many electrons occupy its outer (valence) electron shell.

General Science

The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:


Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee. 

Automotive Information

Engines with radial cylinder configurations are most common in:

aircraft engines

A radial arrangement places cylinders in a circle around the crankshaft and is used almost exclusively in aircraft engines.

Word Knowledge
The impenitent criminal received a harsh penalty, but his remorseful accomplice was released.
Lacking remorse.
General Science

The respiratory and circulatory systems are similar in that they:

transport oxygen

Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.

Arithmetic Reasoning

What is \( \sqrt{\frac{16}{4}} \)?


To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:

\( \sqrt{\frac{16}{4}} \)
\( \frac{\sqrt{16}}{\sqrt{4}} \)
\( \frac{\sqrt{4^2}}{\sqrt{2^2}} \)
\( \frac{4}{2} \)

Electronics Information

Which of the following is not a characteristic of a step-up transformer?

the primary voltage is higher than the secondary voltage

As their names indicate, a step-up transformer is used to step up or increase voltage and a step-down transformer is used to step down or decrease voltage. In a step-up transformer, the secondary voltage is higher than the primary voltage and it has more turns in the secondary winding than in the primary winding.

Word Knowledge
Demeanor most nearly means:
Behavior towards others.
Mechanical Comprehension

A box is resting on a smooth floor. Static friction is present:

when an attempt is made to move the box

For any given surface, the coefficient of static friction is higher than the coefficient of kinetic friction. More force is required to initally get an object moving than is required to keep it moving. Additionally, static friction only arises in response to an attempt to move an object (overcome the normal force between it and the surface).
