Sample Practice Test Questions

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

Universal donor blood can be given to a person with any blood type. Which blood type is the universal donor?

O-negative

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

Mechanical Comprehension

The science that deals with motion and the forces that produce motion is called which of the following?

mechanics

Mechanics deals with motion and the forces that produce motion.

Word Knowledge
Sadie's cowboy hat was incongruous with her black cocktail dress.
inappropriate
Not harmonious, incompatible.
Automotive Information

Which of the following regulates the flow of coolant through the radiator?

thermostat

The thermostat controls coolant (and, through it, engine) temperature by regulating the flow of coolant through the radiator. A bypass tube allows coolant to bypass the radiator and flow back into the water pump when its temperature is low enough that the thermostat is closed.

Automotive Information

A __________ is designed to drive a pair of wheels while allowing them to rotate at different speeds.

differential

A differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. A transaxle is a transmission that incorporates the differential in one package. Most front-wheel drive cars use a transaxle while rear-wheel drive cars use a transmission and separate differential connected via a drive shaft. The differential is incorporated into the drive axle which splits engine power delivered by the drive shaft between the two drive wheels. All-wheel drive cars typically use a transaxle that includes an output shaft to the rear differential.

Shop Information

Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?

rip saw

Wood saws are categorized primarily by their teeth. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.

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.

Mechanical Comprehension

The advantage of using a third-class lever is that it increases:

the speed of the load

A third-class lever is used to increase distance traveled by an object in the same direction as the force applied. The fulcrum is at one end of the lever, the object at the other, and the force is applied between them. This lever does not impart a mechanical advantage as the effort force must be greater than the load but does impart extra speed to the load. Examples of third-class levers are shovels and tweezers.

General Science

In the classification of life, which of the following is not a domain?

animalia

The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
