Sample Practice Test Questions

General Science

During the water cycle, water enters the atmosphere as a gas through which process?

transpiration

The water (hydrologic) cycle describes the movement of water from Earth through the atmosphere and back to Earth. The cycle starts when water evaporates into a gas from bodies of water like rivers, lakes and oceans or transpirates from the leaves of plants.

Word Knowledge
Accommodate most nearly means:
oblige
To give consideration to.
Automotive Information

The steering __________ transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

linkage

The steering linkage is a system of pivots and connecting parts between the steering gear and the control arms. The steering linkage transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

General Science

Elements in the Periodic Table of the Elements are ordered by which of the following?

atomic number

The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.

Electronics Information
series circuit

This circuit diagram represents a(n):

series circuit

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

Electronics Information

Capacitors store:

electricity

Capacitors store electricity 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
Buffer most nearly means:
cushion
Protective barrier.
Shop Information

Which of the following is not a common pliers configuration?

wire

Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.

Math Knowledge
19

If a = 4, b = 2, c = 9, and d = 4, what is the perimeter of this quadrilateral?

19

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 4 + 2 + 9 + 4
p = 19

General Science

Which of the following is the narrowest classification of life?

species

The narrowest classification of life, species, contains organisms that are so similar that they can only reproduce with others of the same species.
