Sam can lift a 176-pound weight for one minute less than Cecil. Arnold can lift the same weight for two minutes less than the total time taken by Sam and Cecil. If y represents Sam's time, find the expression showing the total lifting time for the three people.

  • 4y

  • 2y + 1

  • 4y - 4

  • 2y - 3

Correct answer: 4y

Sam = y minutes

Cecil = y + 1 minute

The sum of Sam's time and Cecil's time y + y + 1 = 2y + 1

Arnold = (2y + 1) - 2 = 2y - 1

Find the sum for Sam, Cecil and Arnold.

(2y + 1) + (2y - 1) = 4y

Which unit of measurement is used for electric frequency?

  • Hertz

  • Ohm

  • Volt

  • Watt

Correct answer: Hertz

A hertz (Hz) is the unit of measurement used for frequency, which is the rate of occurrence of an event within a certain period of time. The hertz is equivalent to cycles per second.

An ohm (R) is the unit of measurement used for electrical resistance. A volt (V) is the unit of measurement used for voltage, or electrical pressure. A watt (W) is the unit used to measure electric power consumption.

83.

A set of tongs is classified as a Class 3 lever. If you are using the tongs to pick up a 2-pound object using 4 pounds of effort, what is the mechanical advantage?

  • 0.5

  • 2

  • 8

  • 16

Correct answer: 0.5

Mechanical advantage is a measure of the force amplification achieved by using a tool or system. In order to find the mechanical advantage of a Class 3 lever, use the following formula:

MA = Load ÷ Effort

Plug in the values.

MA = 2 ÷ 4 = 0.5

84.

Read the passage and then answer the following question.

What does the author mean by the phrase reinventing of the wheel in Sentence 11?

  • Recreating something that has already been created

  • Finding new, innovative ways to enhance something

  • Overanalyzing others’ previous decisions

  • Using circle graphs to brainstorm

Correct answer: Recreating something that has already been created

Throughout the passage, the author is informing the reader that data visualization has been around for hundreds of years; however, it has not been studied in recent times. Therefore, the lack of knowledge has caused young visualizers to recreate maps that have already been created (i.e., reinventing of the wheel) because they have not received proper geographical training.

Sentence 11 is not implying that there are new and innovative ways to enhance something. Reinventing the wheel also does not mean overanalyzing others' decisions or using circle graphs to brainstorm.

85.

Choose the option that best defines the word in italics.

The brevity of the film allowed us to get dinner before the restaurant closed.

  • Shortness

  • Encore

  • Horror

  • Popularity

Correct answer: Shortness

Brevity refers to the concise use of words in writing or speech. Shortness, therefore, matches the definition of brevity the closest of all the given options.

Encore is the repeated or additional performance of something, which would extend the movie rather than making it shorter. Horror and popularity are not related to the definition of brevity and, therefore, shortness is the correct answer.

86.

Which of the following time periods occurred during the Mesozoic Era?

  • Jurassic

  • Tertiary

  • Permian

  • Mesoproterozoic

Correct answer: Jurassic

The Mesozoic Era lasted about 180 million years and ended about 66 million years ago. The three time periods that occurred during the Mesozoic Era are the Jurassic, Triassic, and Cretaceous periods.

The two time periods that occurred during the Cenozoic Era are the Quaternary and Tertiary periods. The six time periods that occurred during the Paleozoic Era are the Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian periods. The three time periods that occurred during the Proterozoic Era are the Neoproterozoic, Mesoproterozoic, and Paleoproterozoic periods.

87.

Read the passage and then answer the following question.

What does the author of the passage mean when stating that newer theories "advocated a reverse direction of the causal arrow"?

  • It is social change that triggers technological innovation

  • Technological change drives historical processes

  • Society and technology influence each other

  • The source of technological innovation depends on the historical context

Correct answer: It is social change that triggers technological innovation

In the second sentence of the passage, the author states that the first philosophers of technology believed that technological change drove historical processes. Since that time, newer views actually believe the opposite ("a reverse direction of the causal arrow"), meaning that social change triggers technological innovation.

As stated above, original theories believed that technological change drove historical processes, but the reverse means that historical processes actually drive technological change. The author does state that society and technology interact, but specifically states that historical and societal factors strongly influence technology. The author does not address the source of technological innovation, so this answer is also incorrect.

88.

A machine is operating with two pulleys that are connected by a belt. The pulley on the left is 9 inches in diameter, and the pulley on the right is 9 inches in diameter. Which of the following statements is true?

  • The two pulleys will run at the same speed

  • The pulley on the left will run faster than the pulley on the right

  • The pulley on the left will run slower than the pulley on the right

  • Only the pulley on the right will run

Correct answer: The two pulleys will run at the same speed

When two pulleys are connected by a belt, they will run at the same speed if they are the same size. If the two pulleys are not the same size, the pulley that is larger will run slower than the smaller one because it makes fewer turns to move the belt.

89.

Which of the following support structures has the most strength?

  • One with a triangular design

  • One with a rectangular design

  • One with a horizontal design

  • One with a circular design

Correct answer: One with a triangular design

A support structure that is built using a triangular design is the strongest, since it will keep its shape unless it completely breaks apart.

Rectangular, horizontal, and circular support structures can easily bend out of shape due to their individual constructions and weight distributions.

90.

An individual’s heart is a component of which body system?

  • Circulatory

  • Respiratory

  • Nervous

  • Muscular

Correct answer: Circulatory

The circulatory system is the body’s transportation system. It transports items such as oxygen, waste products, and hormones throughout the body. The heart, arteries, veins, and capillaries are all components of the circulatory system that aid in transportation.

The respiratory system consists of the lungs, trachea, bronchi, and diaphragm. The nervous system consists of the brain, spinal cord, and neurons. The muscular system consists of skeletal, smooth, and cardiac muscles (but not the heart itself).

91.

Silicon is an element with 4 valence electrons. What does this tell us about one atom of silicon?

  • There are 4 electrons in the atom's outer shell

  • The atom has no more than 4 electrons 

  • There are 4 electrons in the atom's inner shell

  • It takes a minimum of 4 electrons for the atom to conduct electricity

Correct answer: There are 4 electrons in the atom's outer shell

The valence shell is the outer shell of an atom. Therefore, since silicon has 4 valence electrons, this tells us that there are 4 electrons in the outer shell of the silicon atom.

The remaining answer options are incorrect. The silicon atom actually has 14 electrons total, occupying 3 shells. The inner shell has 2 electrons. Silicon is a semiconductor, meaning the valence shell is exactly half full.

92.

What is the ratio of 8 feet to 28 inches?

  • 24:7

  • 2:7

  • 5:3

  • 7:24

Correct answer: 24:7

When comparing distances, we have to make sure that the terms are the same. To accomplish this, convert to inches.

Multiply 8 by 12, since there are 12 inches in a foot. This gives us 96 inches.

The ratio then becomes 96 inches to 28 inches, or 96:28.

Divide both numbers by 4 to reduce the ratio to 24:7.

93.

Change 1/8 to a decimal.

  • 0.125

  • 0.25

  • 0.8

  • 0.08

Correct answer: 0.125

To change a fraction to a decimal, divide the numerator by the denominator.

1/8 = 1 ÷ 8 = 0.125

94.

In order to remove a fastener that is extremely tight, which type of wrench should you use?

  • A longer box-end wrench

  • A longer open-end wrench

  • A shorter box-end wrench

  • A shorter open-end wrench

Correct answer: A longer box-end wrench

The longer the wrench, the more leverage and torque it can apply to loosen a fastener. Box-end wrenches are also better at loosening tight fasteners because they can wrap completely around the head of the bolt.

Open-end wrenches are made for speed as they can slide easily on and off a fastener. As stated above, shorter wrenches have less leverage and twisting force than longer wrenches and are not a good choice to use when a fastener is particularly tight.

95.

All of the following methods except ______ use molten metal for fastening.

  • Gluing

  • Welding

  • Soldering

  • Brazing

All of the following methods except gluing use molten metal for fastening.

Gluing is a process that uses an adhesive to fasten objects to one another. It is often used in woodworking, and does not work well with metals.

Fastening objects using molten metal is done by welding, soldering, and brazing. Welding is a process that joins metals by causing fusion when the base metal is melted. Soldering is the fastening method that is best used for plumbing and electrical equipment. Brazing is the fastening method that uses a bronze joining material and is used to fasten metal objects.

96.

Where is the most likely place for a rope to snap?

  • Near the place where the rope is being pulled

  • Near the object the rope is pulling

  • At the end farthest from the source of tension

  • More information about the amount of tension and weight of the object being pulled is needed

Correct answer: Near the place where the rope is being pulled

Barring any imperfections or weaknesses in the material under tension, the most likely place for a rope or cable to snap is near the place where the rope or cable is being pulled. This is due to the amount of tension in that portion of the rope.

The end farthest from the source of tension (the source of the pulling) is not the most likely place for the rope to snap. Additional information is not needed to determine the answer, as in any situation the tension is greater near where it is being pulled than the object itself.

97.

Where is the moon located during a solar eclipse?

  • Between the sun and the earth

  • Behind the earth

  • Behind the sun

  • The moon is not part of the solar eclipse

Correct answer: Between the sun and the earth

During a solar eclipse, the moon passes between the sun and the earth, completely or partially blocking the sun from view. This happens only at a new moon, when the sun and the moon are aligned.

During a lunar eclipse, the moon is behind the earth, which is also in a straight line with the sun. As stated above, the moon is a significant part of a solar eclipse.

98.

You are looking at a machine that has two gears. The driving gear has 8 teeth, and the driven gear has 32 teeth. What is the mechanical advantage of the gear?

  • 4

  • 256

  • 40

  • 24

Correct answer: 4

Mechanical advantage is a measure of the force amplification achieved by, in this case, using a gear system. In order to find the mechanical advantage of a gear, you will need to divide the number of teeth on the driven gear by the number of teeth on the driving gear.

MA = Number of teeth on the driven gear ÷ Number of teeth on the driving gear

Insert the values and solve.

MA = 32 teeth ÷ 8 teeth = 4

99.

In her garden, Sylvia picked 45 flowers in three days. Each day she picked five more flowers than the previous day. How many flowers did Sylvia pick from her garden on the third day?

  • 20

  • 25

  • 15

  • 10

Correct answer: 20 

Let x = the number of flowers Sylvia picked on day 1.

Set up the following equation and solve for x:

x + (x + 5) + (x + 10) = 45

Combine like terms.

3x + 15 = 45

Solve.

3x = 30

x = 10

Therefore, we know that Sylvia picked 10 flowers on the first day.

Since each day she picked 5 more flowers than the previous day, find the number she picked the second and third days.

Second day: 10 + 5 = 15

Third day: 15 + 5 = 20

100.

Threads are identified by their:

  • Pitch

  • Tightness

  • Lubrication

  • Versatility

Correct answer: Pitch

Threads are identified by their pitch, which is the distance between threads expressed in millimeters. Therefore, a thread pitch of 1.25 means the distance between two threads is 1.25 mm. 

The remaining answer options are incorrect. Threads are identified by their pitch, not their tightness, lubrication, or versatility.
