Sample Practice Test Questions

Automotive Information

The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.

brake fluid

The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.

Word Knowledge
Jonah regretted entangling Parker in his legal difficulties.
embroil
To involve in trouble.
Electronics Information
AC source

This circuit component symbol represents a(n):

AC source

In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.

Electronics Information

Capacitors are charged by what type of current?

direct

Capacitors store voltage and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

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

This circuit component symbol represents a(n):

fuse

Fuses are thin wires that melt when the current in a circuit exceeds a preset amount. They help prevent short circuits from damaging circuit components when an unusually large current is applied to the circuit, either through component failure or spikes in applied voltage.

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
Turmoil most nearly means:
chaos
Extreme confusion, agitation.
General Science

Which of the following temperatures is least like the others?

32°F

Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.

General Science

Which of the following is a decomposer?

fungi

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.
