Sample Practice Test Questions

Word Knowledge
The impatient Zoe found the longwinded lecture interminable.
ceaseless
Never ending, or seemingly endless.
Shop Information

Which of the following nuts provide appendages that allow tightening and loosening by hand?

wing

Wrenches are used with threaded fasteners like bolts and nuts. A bolt has external threads while a nut has internal threads and this thread pattern combination allows them to lock together and act as fasteners. Nuts come in a variety of configurations including wing nuts which provide appendages that allow tightening and loosening by hand, slotted nuts that use a cotter pin to lock the nut in place and prevent it from loosening, and lock nuts that also prevent loosening via nylon in their threads. Threads are identified by pitch which is the number of threads per inch.

Automotive Information

Which of the following is the name for a transmission that incorporates the differential in one package?

transaxle

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.

Automotive Information

Which of the following is not part of an engine's cooling system?

air conditioner

The purpose of an automobile engine's cooling system is to circulate coolant around the engine so it can absorb and dissipate heat. The water pump pumps coolant through the various components in the system and the radiator cools down coolant after it has heated up after passing through the engine. The thermostat controls the flow of coolant based on engine temperature while the cooling fan draws air through the radiator when the car isn't moving fast enough for unforced air to cool things down on its own.

Arithmetic Reasoning

A circular logo is enlarged to fit the lid of a jar. The new diameter is 40% larger than the original. By what percentage has the area of the logo increased?

20%

The area of a circle is given by the formula A = πr2 where r is the radius of the circle. The radius of a circle is its diameter divided by two so A = π(\( \frac{d}{2} \))2. If the diameter of the logo increases by 40% the radius (and, consequently, the total area) increases by \( \frac{40\text{%}}{2} \) = 20%

Word Knowledge
The soldiers cherished the kindly Nurse Nightingale for her pathos.
compassion
Sympathetic pity.
Automotive Information

Coolant is circulated through the engine by the:

water pump

The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.

Word Knowledge
Augment most nearly means:
enhance
To make greater.
Math Knowledge

What is the circumference of a circle with a radius of 18?

36π

The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:

c = πd
c = π(2 * r)
c = π(2 * 18)
c = 36π

Word Knowledge
Jennifer's outspoken criticism of the meal disoncerted the waiter.
unnerve
To throw into confusion.
