What is the most dangerous toxic gas emitted by an engine's exhaust?

  • Carbon monoxide

  • Nitrogen

  • Carbon dioxide

  • Argon

Correct answer: Carbon monoxide

Even though the catalytic converter's purpose is to convert highly toxic gases into less dangerous ones, carbon monoxide is a by-product of the catalytic converter and is sent along with other exhaust gases through the muffler. Carbon monoxide is odorless and colorless, and it is extremely important that it is routed in a way that it does not come in contact with the drivers or passengers.

The remaining answer options are incorrect. Nitrogen, carbon dioxide, and argon are all gases that are not necessarily immediately dangerous to humans if inhaled.

182.

Read the passage and then answer the following question.

Which of the following options would be the best title for the passage?

  • The Revolution of the Cocoa Bean

  • The Manufacturing of Chocolate

  • Chocolate Creations

  • Spain Discovers Cocoa

Correct answer: The Revolution of the Cocoa Bean

When identifying a title for a passage, the best one is the one that describes the passage’s main idea. In the given passage, the author introduces Mexico as being the first country to use the cocoa bean, and the author continues by discussing how other countries discovered, used, and manufactured it. Therefore, the author takes you through the physical and cultural transformation of the cocoa bean.

"The Manufacturing of Chocolate" would not be a good title, as the passage does not describe how chocolate is made. "Chocolate Creations" also does not apply, as the passage does not talk about different foods made out of chocolate. The passage does state that Spain was the first European country to use cocoa, but Sentence 1 implies that Mexico was using cocoa before the Spaniards began doing the same.

183.

What is the best definition of the italicized word in the sentence below?

Though Sally wanted to start her own business, she was hampered by her lack of funds.

  • Hindered

  • Encouraged

  • Simplified

  • Assisted

Correct answer: Hindered

To be hampered is to be slowed down or impeded by someone or something. To be hindered means to encounter difficulties that create delays, so it is the best answer.

Hampered does not mean encouraged or simplified, so these answers are incorrect. Assisted is the opposite of hampered, so it is also incorrect.

184.

Power is calculated by multiplying volts by:

  • Current

  • Resistance

  • Distance

  • Energy

Correct answer: Current

Power refers to the actual rate at which energy is provided to and consumed by an electric circuit. It is expressed in watts and is calculated by multiplying voltage applied to the circuit by the current that flows in the circuit, or P = IV.

The remaining answer options are incorrect. The equation to determine power does not include resistance, distance, or energy.

185.

Add:

856 + 291 =

  • 1,147

  • 1,047

  • 1,137

  • 1,037

Correct answer: 1,147

In order to add two sets of numbers together, work from the right (ones place) and move to the left (hundreds place).

   856
+ 291

Calculate 6 + 1, which is 7.

   856
+ 291
=    7

Calculate 5 + 9, which is 14. Bring down the 4 and carry the 1 to the next column.

   1   
   856
+ 291
=   47

Calculate 8 + 2, which is 10. Add the 1 that was carried to get 11.

     1
     856
  + 291
= 1,147

Therefore, 856 + 291 = 1,147

186.

Tom works in a daycare center with three-, four-, and five-year-old children. The total enrollment at the center is 30 children. If two out of five children are five years old, how many children are five years of age?

  • 12

  • 10

  • 6

  • 15

Correct answer: 12

This problem can be solved using ratios. If two out of five children are five years old, the ratio used to solve the problem is 2:5. In the following equation used to solve the problem, x represents the unknown number of children who are five years old:

2/5 = x/30

Cross multiply: 5x = 2 × 30

5x = 60

x = 60/5

x = 12

Twelve children are five years old.

187.

Choose the option that best defines the word in italics.

The quarterback who is most adept is likely to lead his team to victory.

  • Proficient

  • Handsome

  • Fast

  • Strong

Correct answer: Proficient

It is clear from this sentence that a person who is adept is very good at something. Proficient means competent, which makes sense in this context, as the quarterback must be competent in order to help his team win.

Whether a football team wins or not does not depend on how handsome the quarterback is, so this can be eliminated. Although being fast and strong may help a quarterback become adept, the sentence refers to someone who is skilled and competent.

188.

Read the passage and then answer the following question.

Which of the following is cited by the author of the passage as one reason scholars have recently begun to regard Alexander in a negative light?

  • Excessive drinking

  • Plundering

  • Having affairs out of wedlock

  • Abusing his children

Correct answer: Excessive drinking

The author of the passage states that scholars have recently emphasized Alexander the Great's "conquering bloodlust, his megalomania, or alleged alcoholism." Since excessive drinking is the same as alcoholism, this is the correct answer.

The remaining answer options are incorrect. Though Alexander may have engaged in plundering, extramarital affairs, or child abuse, the author does not specifically state that these are reasons scholars have recently changed their views about Alexander the Great's character.

189.

A water tank can hold 372 gallons of water. It is a quarter empty and has to supply water to 7 families. If each family must get 30 gallons, what amount of water will remain in the tank?

  • 69 gallons

  • 117 gallons

  • 210 gallons

  • 93 gallons

Correct answer: 69 gallons

If the tank is a quarter empty, then it is three-quarters full. Multiply to find the amount of water in the tank.

3/4 × 372 = 279 gallons

Each family gets 30 gallons, so multiply to find the total number of gallons.

30 gallons × 7 families = 210 gallons

Subtract to find how much is left.

279 - 210 = 69 gallons

190.

Choose the option that best defines the word in italics.

The security guard asked the people in line not to obstruct the doorway.

  • Impede

  • Clear

  • Close

  • Pass

Correct answer: Impede

To obstruct means to block passage through or against something (or someone). Impede, which means hinder or delay, has the closest meaning to obstruct among the given options.

Clear is the opposite of obstruct. Pass means to move in a specific direction, which is different from the meaning of obstruct. Close means to shut off access to something, but impede is still the best answer.

191.

Which type(s) of blood can donate to people with all types of blood?

  • O

  • A and B

  • B and O

  • AB and O

Correct answer: O

A blood type is a classification of blood based on the presence or absence of antigenic substances on the surface of red blood cells. The O blood type does not have A or B antigens on red cells, so it can donate to all types of blood. A person with the O blood type can only receive O blood, however, because the presence of A or B antigens can trigger that person's immune system. 

Because of the danger stated above to the blood recipient's immune system, the A blood type can receive A and O blood, but it can only donate to A and AB blood types. The B blood type can receive B and O blood, but it can only donate to B and AB blood types. The AB blood type can receive all types of blood, but it can only donate to AB blood types.

192.

A club has an estimated 4,200 members. A third of the members are children, 4/7 of the remainder are women, while the rest are men. Find the number of adult men who are members of the club.

  • 1,200

  • 2,800

  • 1,400

  • 1,800

Correct answer: 1,200

Total number of members = 4,200

1/3 of the members are children, so 4,200 × 1/3 = 1,400 children

Subtract the number of children from the number of members.

4,200 - 1,400 = 2,800

Of the number of adult members, 4/7 are women.

2,800 × 4/7 = (2,800 × 4)/7 = 1,600

Subtract the number of women from the total number of adults

2,800 - 1,600 = 1,200

There are 1,200 adult men who are members of the club.

193.

In this image of an equilateral triangle, what does ∠A equal?

  • 60º

  • 90º

  • 45º

  • More information is needed

Correct answer: 60º

An equilateral triangle is one in which all angles and sides are equal. Since all the angles of a triangle total 180º, each angle of an equilateral triangle is 60º.

194.

All of the following materials are found in the earth's mantle except which one?

  • Carbon monoxide

  • Iron

  • Magnesium

  • Calcium

Correct answer: Carbon monoxide

The earth's mantle lies below the crust, which is the outermost layer of the earth's surface. It does not contain carbon monoxide as a major element, though does contain some carbon dioxide.

The mantle is made up of iron, magnesium, and calcium and is hotter and denser than the earth's surface due to increased pressure and temperature. It is roughly 3,500 kilometers thick.

195.

Which of the following is a polynomial?

  • 3a + 5b + c

  • x + y

  • x2

  • √x

Correct answer: 3a + 5b + c

A polynomial is an algebraic expression of more than two terms. This example has three separate terms (3a, 5b, and c), so it is a polynomial.

x + y is a binomial because it is an expression with two separate terms (x and y). x2 and √x are monomials because they each consist of only one term. 

196.

If you were to glue two pieces of wood together, which of the following tools would you most likely use to hold them together while the glue sets?

  • Bar clamp

  • Locking pliers

  • Arc-joint pliers

  • Adjustable wrench

Correct answer: Bar clamp

A bar clamp is also known as an "F-clamp" and consists of two horizontal bars held together by a vertical bar. It is generally used to hold objects together while glue is setting; therefore, it would be the best tool to use in this case.

Locking pliers are generally used when you need to have a strong hold on something; however, they can easily damage objects due to their locking system. Arc-joint pliers and adjustable wrenches are generally used to turn bolts or other objects.

197.

You are looking at a machine that has a sheave system. The driving sheave has a diameter of 9 inches, and the driven sheave has a diameter of 27 inches. What is the mechanical advantage of the sheave system?

  • 3

  • 1/3

  • 6

  • 1.5

Correct answer: 3

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 sheave system, divide the driven diameter by the drive diameter.

MA = Driven Diameter ÷ Drive Diameter

MA = 27 ÷ 9 = 3

198.

What is the circumference of a circle that has a radius of 6?

  • 37.68

  • 12

  • 16.99

  • 3

Correct answer: 37.68

The circumference of a circle is equal to πd, and d is equal to 2r.

Diameter = 2r = 2(6) = 12

Circumference = πd = 12π

Since π = 3.14, multiply it by 12.

Circumference = 12(3.14) = 37.68

199.

How many feet are in 7,224 inches?

  • 602 feet

  • 722.4 feet

  • 903 feet

  • 86,688 inches

Correct answer: 602 feet

There are 12 inches in one foot; therefore, there are 602 feet in 7,224 inches (7,224/12 = 602).

200.

What is the main advantage a soldering gun has over a soldering iron?

  • The soldering gun has a quick warm-up cycle

  • The soldering gun is electrically powered

  • The soldering gun is more precise

  • Soldering guns can be used in sheet metal work

Correct answer: The soldering gun has a quick warm-up cycle

Soldering guns have a two-step trigger that allows the user to select a low or high heat setting. The main advantage the soldering gun has over a soldering iron is a rapid warm-up cycle. Soldering guns also usually have lights built into them to illuminate the work.

The remaining answer options are incorrect. Both soldering irons and soldering guns are powered by electricity, and each tool is equally precise. Both types of tools can also be used in sheet metal work.
