Sample Practice Test Questions

Word Knowledge
It was incumbent on Jack to attend his father's retirement party.
oblilgatory
Necessary as a duty or responsibility.
General Science

Carbohydrates are found in:

sugars and starches

Carbohydrates are major sources of energy for the body and are found in sugars (fruit, cane sugar, beets) and starches (bread, rice, potatoes, pasta).

Electronics Information

One of the lights on your Christmas tree burns out and this causes the rest of the lights connected to that strand to go dark. How are the lights in that strand connected?

series

Lights connected in series form a chain with each light connecting to adjacent lights via one wire. Therefore, if one of the lights burns out and breaks the series, none of the other lights will receive power and they'll go dark. Lights connected in parallel each connect to the positive and negative nodes of the power source and would not go dark if one of their neighbors burnt out.

Electronics Information

The ampere is a unit of measurement for:

current

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.

Math Knowledge

Simplify (9a)(8ab) + (7a2)(8b).

128a2b

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(9a)(8ab) + (7a2)(8b)
(9 x 8)(a x a x b) + (7 x 8)(a2 x b)
(72)(a1+1 x b) + (56)(a2b)
72a2b + 56a2b
128a2b

Mechanical Comprehension

Which of the following represents the force a surface exerts when an object presses against it?

normal force

Normal force (FN) represents the force a surface exerts when an object presses against it.

Electronics Information

The formula specifying Ohm's law is which of the following?

V = IR

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

Mechanical Comprehension

An object's resistance to changes in direction is known as:

inertia

The more mass a substance has the more force is required to move it or to change its direction. This resistance to changes in direction is known as inertia.

Arithmetic Reasoning

The __________ is the smallest positive integer that is a multiple of two or more integers.

least common multiple

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.

Word Knowledge
