Sample Practice Test Questions

Word Knowledge
Her excellent lecture illuminated the complicated subject of nuclear physics.
elucidate
To make clear.
General Science

Which of these is important for the body's maintenance, growth, and repair?

protein

Found in both animal sources (meat, fish, eggs, cheese) and vegetables (beans, nuts, some grains), proteins are important for the body's maintenance, growth, and repair.

Word Knowledge
The singer's prominence ensured that the concert would sell out.
renown
Importance.
General Science

Which of the following indicates the correct reproductive sequence?

ovum → zygote → fetus

During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.

General Science

Cirrus clouds are thin, wispy clouds composed of ice crystals. At what elevation to cirrus clouds form?

high-altitude

Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.

Mechanical Comprehension

Which of these will have the most impact on the kinetic energy of an object?

its speed

Kinetic energy is the energy of movement and is a function of the mass of an object and its speed: \(KE = {1 \over 2}mv^2\) where m is mass in kilograms, v is speed in meters per second, and KE is in joules. The most impactful quantity to kinetic energy is velocity as an increase in mass increases KE linearly while an increase in speed increases KE exponentially.

Word Knowledge
Retroactive most nearly means:
retrograde
effective as of a prior time or condition.
Word Knowledge
Colossal most nearly means:
gigantic
Immense, enormous.
Automotive Information

Which of the following is not a component in the engine lubrication system?

differential

In engine lubrication, oil remains in the oil pan until the engine is turned on. It then gets sucked up the pickup tube by the oil pump and pressurized. This pressure is moderated by the pressure relief valve and the oil is fed through the oil filter into the engine to lubricate it.

Mechanical Comprehension

Collinear forces:

act along the same line of action

Collinear forces act along the same line of action, concurrent forces pass through a common point and coplanar forces act in a common plane.
