Sample Practice Test Questions

Automotive Information

The vehicle's computer system gets data from:

sensors

Sensors provide the data necessary for the vehicle's computer to make decisions and monitor everything from simple vehicle information like tire pressure to complexities like the chemical content of an engine's exhaust.

Word Knowledge
Allison's painting met with plaudits from the critics, who had dismissed her earlier work.
kudos
Enthusiastic approval.
Word Knowledge
Derivative most nearly means:
banal
Lacking originality.
Mechanical Comprehension

The force exerted on an object due to gravity is called:

weight

Mass is an intrinsic property of matter and does not vary. Weight is the force exerted on the mass of an object due to gravity and a specific case of Newton's Second Law of Motion. Replace force with weight and acceleration with acceleration due to gravity on Earth (g) and the result is the formula for weight: W = mg or, substituting for g, weight equals mass multiplied by 9.8 m/s2.

General Science

During digestion, after proteins are broken down where does the undigested food go next?

small intestine

Food is mixed with gastric acid and pepsin in the stomach to help break down protein.

Word Knowledge
Onset most nearly means:
start
Beginning.
General Science

Molecules and atoms that are outputs from a chemical reaction are known as which of the following?

products

During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).

Word Knowledge
Rashid made the untenable statement that George Washington was the second president of the United States.
baseless
Not able to be defended.
General Science

An electrically charged atom is a(n):

ion

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.

Arithmetic Reasoning

A machine in a factory has an error rate of 6 parts per 100. The machine normally runs 24 hours a day and produces 5 parts per hour. Yesterday the machine was shut down for 6 hours for maintenance.

How many error-free parts did the machine produce yesterday?

84.6

The hourly error rate for this machine is the error rate in parts per 100 multiplied by the number of parts produced per hour:

\( \frac{6}{100} \) x 5 = \( \frac{6 \times 5}{100} \) = \( \frac{30}{100} \) = 0.3 errors per hour

So, in an average hour, the machine will produce 5 - 0.3 = 4.7 error free parts.

The machine ran for 24 - 6 = 18 hours yesterday so you would expect that 18 x 4.7 = 84.6 error free parts were produced yesterday.
