Sample Practice Test Questions

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).

General Science

Which of blood component carries oxygen?

red blood cells

Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.

Math Knowledge

What is 4a7 - 9a7?

-5a7

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

4a7 - 9a7 = -5a7

General Science

A biological community of interacting organisms and their physical environment is known as:

ecosystem

An ecosystem is a biological community of interacting organisms and their physical environment. This includes both the biotic (living) and abiotic (non-living).

Automotive Information

Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:

bushings

Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.

Word Knowledge
Manifest most nearly means:
evident
Obvious.
Word Knowledge
The gargantuan monster towered over the ten–story bulding.
enormous
Gigantic.
Mechanical Comprehension

Specific gravity is a comparison of the density of an object with the density of:

water

Specific gravity is the ratio of the density of equal volumes of a substance and water and is measured by a hyrdometer.

Mechanical Comprehension

Hydraulics is the transmission of force through the use of which of the following?

liquids

Hydraulics is the transmission of force through the use of liquids. Liquids are especially suited for transferring force in complex machines because they compress very little and can occupy very small spaces. Hydraulic pressure is calculated by dividing force by the area over which it is applied: P = F/A where F is force in pounds, A is area in square inches, and the resulting pressure is in pounds per square inch (psi).

Word Knowledge
Curtail most nearly means:
shorten
To make less.
