Read the passage, and then answer the following question.

Which of the following changes should be made to Sentence 12?

  • Change “previous” to “previously”

  • Change “were” to “was”

  • Change “community” to “Community”

  • Change “marginal” to “marginally”

Correct answer: Change “previous” to “previously”

The adjective “previous” should be rewritten as the adverb “previously” as it is modifying the verb “denounced.” 

The plural verb “were” is referring to the three women, not the devil; therefore, it should remain plural. The word community is not a proper noun and should not be capitalized. The adjective “marginal” is not modifying a verb; therefore, it should not be changed to the adverb “marginally.”

  • 430,011

  • 400,311

  • 0.043011

  • 43,011

Correct answer: 430,011

400,311 reads four hundred thousand three hundred eleven, 0.043011 reads forty-three thousand eleven hundred thousandths, and 43,011 reads forty-three thousand eleven.

A marble rolled down a hill at an average speed of 20 feet / minute. The path it traveled was 120 feet long. How long did it take the marble to roll down the hill?

  • 6 minutes

  • 1 hour

  • 0.16 minutes

  • 0.16 hours

Correct answer: 6 minutes

To solve for average speed, the equation is average speed = distance / time. 

Rearrange the equation to solve for time: time = distance / average speed.

Time = 120 feet / (20 feet / minute)

Time = 6 minutes

Read the passage, and then answer the following question.

What do all four presidential assassinations have in common?

  • All four assassinations were committed using a gun

  • All four presidents were shot in the back

  • All four assassinations occurred on a Friday

  • All four presidents died instantly

Correct answer: All four assassinations were committed using a gun

All four presidents were shot; therefore, you can assume that all of the assassinations were committed using a gun. 

Not all of the presidents were shot in the back. Lincoln was shot in the back of the head, McKinley was shot in the abdomen, and Kennedy was shot in the neck and the head. All of the presidents except Garfield, who was assassinated on a Saturday, were assassinated on a Friday. Only Kennedy died instantly.

Read the passage, and then answer the following question.

Which of the following permitted the Union to seize the belongings of the Confederates?

  • Confiscation Act

  • Fugitive Slave Act

  • Emancipation Proclamation

  • Civil Rights Act

Correct answer: Confiscation Act

The Confiscation Act provided the Union with the right to seize the belongings of the Confederates. This act was put into place by Congress in the early months of the American Civil War and allowed the confiscation of any property that was being used to support the Confederate independence effort. 

The Fugitive Slave Act required the return of any escaped slave to his or her owner, the Emancipation Proclamation freed slaves, and the Civil Rights Act aimed to end discrimination in the United States.

51.

How many moles are contained in 0.455 L of a 7.182 M solution?

  • 3.268

  • 0.063

  • 15.785

  • 63.353

Correct answer: 3.268

Find the number of moles by using the molarity formula: molarity = moles of solute / liter of solution. 

Thus, 0.455 L x (7.182 M / 1.0 L) = 3.268 moles.

52.

5 1/4 ÷ 2 1/2 = ?

  • 2 1/10

  • 13 1/8

  • 2 1/8

  • 8 1/8

Correct answer: 2 1/10 

In order to simplify the expression, convert the mixed numbers to improper fractions.

5 1/4 = 21/4

2 1/2 = 5/2

5 1/4 ÷ 2 1/2 = 21/4 ÷ 5/2

To divide by a fraction, multiply by its reciprocal.

21/4 ÷ 5/2 = 21/4 × 2/5, or 42/20

Reduce to its lowest terms.

42/20 ÷ 2/2 = 21/10

Finally, express 21/10 as a mixed number.

21/10 = 2 1/10

53.

In 1859, Charles Darwin first introduced which of the following theories?

54.

Joyce runs 10 miles in 60 minutes. How much longer does it take her to run 12 miles?

  • 12 minutes

  • 18 minutes

  • 10 minutes

  • 15 minutes

Correct answer: 12 minutes

Set up a proportion to find out how long it will take Joyce to run 12 miles.

10 miles/60 minutes = 12 miles/x minutes

10/60 = 12/x

720 = 10x

x = 72 minutes

Subtract 72 minutes from 60 minutes to find the difference.

72 - 60 = 12 minutes

55.

4/5 is how many times greater than 2/5?

  • 2

  • 1.5

  • 1.2

  • 4

Correct answer: 2 

The mathematical expression is 4/5 = x(2/5).

Solve:

4/5 = x(2/5)

x = 4/5 ÷ 2/5 = 4/5 × 5/2 = 20/10 = 2

x = 2

Read the passage, and then answer the following question.

Which of the following would describe the majority of the Confederate soldiers who fought in the American Civil War?

  • Young, white men

  • Black men in their twenties and thirties

  • Elite, middle-aged men

  • Poor white and black men

Correct answer: Young, white men

The majority of Confederate soldiers who fought in the American Civil War were young, white men. This is one reason that the deaths of the soldiers, many of whom were the main breadwinners for their families, was so devastating to the southern economy. 

The remaining answers do not accurately describe the majority of Confederate soldiers; although, there were certainly both black and white soldiers, ranging in age from young teenagers to older men.

Arrange in descending order:

5, 1/6, 280%

  • 5, 280%, 1/6

  • 280%, 1/6, 5

  • 5, 1/6, 280%

  • 1/6, 280%, 5

Correct answer: 5, 280%, 1/6

Convert all the values to decimals to determine the appropriate order:

5 = 5.0

1/6 = 0.16667

280% = 2.80

Therefore, in descending order - which means from greatest to least - the values are:

5.0, 2.80, 0.16667 or 5, 280%, 1/6

Nick has 2 3/4 pounds of wheat flour, while his friend has 4 1/5 pounds of wheat flour. How many pounds of flour do they have altogether?

  • 6 19/20 pounds

  • 7 1/20 pounds

  • 6 9/20 pounds

  • 6 1/25 pounds

Correct answer: 6 19/20 pounds

First, change the fractions to improper fractions by multiplying the denominator by the base number and adding it to the numerator.

2 3/4 = 4 × 2 + 3 = 11/4

4 1/5 = 5 × 4 + 1 = 21/5

Next, find a common denominator by multiplying the two denominators.

4 × 5 = 20

Now convert each fraction so that both have denominators of 20.

11/4 × (5/5) = 55/20

21/5 × (4/4) = 84/20

Add the fractions together.

55/20 + 84/20 = 139/20

To convert to a proper fraction, divide 139 by 20.

139/20 = 6 19/20 pounds

John adopted his dog exactly 5 years and 12 days ago. At this instant, how many minutes has John had his dog? (Ignore leap years.)

  • 2,645,280 minutes

  • 2,217,116 minutes

  • 3,098,732 minutes

  • 1,872,234 minutes

Correct answer: 2,645,280 minutes

Start by finding the number of days in 5 years.

1 year = 365 days

1 year x 5 = 365 days x 5 = 1,825 days

Add the 12 days.

1,825 days + 12 days = 1,837 days

Convert the number of days to hours.

1 day = 24 hours

1 day x 1,837 = 24 hours x 1,837 = 44,088 hours

Convert the number of hours to minutes.

1 hour = 60 minutes

1 hour x 44,088 = 60 minutes x 44,088 = 2,645,280 minutes

Read the passage, and then answer the following question.

According to the passage, when are about a quarter of a person's daily calories consumed?

  • Between meals

  • At breakfast

  • After dinner

  • On the run

Correct answer: Between meals

The passage states in the third sentence that "...nearly a quarter of the calories in the American diet, about 504 per day, are eaten between meals." Though many of these snacks are eaten on the run, the passage does not explicitly say that all extra calories consumed are eaten at this time.
