Read the supporting details then correct the sentence below.

Sentence 11: A maglev line between Hamburg and Berlin is under consideration in Germany with private financing and potentially with additional support from individual states in northern Germany along the proposed route.

Which of the following changes should be made to correct sentence 11?

  • Change “northern” to “Northern”

  • Insert a comma after “Hamburg”

  • Change “states” to “States”

  • Change “from” to “for”

Correct answer: Change “northern” to “Northern”

In order to correct sentence 11, you should change “northern” to “Northern.” In this sentence, “northern” is being used to represent a section of Germany; therefore, it should be capitalized. If you used “northern” to show direction (head north), it would not be capitalized. 

When there are only two items in a list, you do not need to separate them with a comma; therefore, you do not need a comma after “Hamburg.” The other answer options are not options that would make the sentence grammatically correct.

64.

Read the supporting details then answer the following question.

In regard to the passage, which of the following statements best answers when bearded irises bloom?

  • Different varieties flower at different times

  • Only during the months that they are planted

  • They have to have full sun to bloom

  • They only bloom from April to June

Correct answer: Different varieties flower at different times

This is found in the first sentence of the second paragraph. You can eliminate “only during the months that they are planted,” as the passage does not state or imply this. It is true that they have to have full sun to bloom, but that does not answer when they bloom. Irises do bloom from April to June, but that also depends on what varieties are planted, as some varieties can rebloom after the summer resting period.

65.

Brandon's math average is based on five tests. Brandon's test scores were 75, 83, 94, 85, and 98. What is Brandon's math average for the five tests?

  • 87

  • 77

  • 80

  • 85

Correct answer: 87

To find the average, take the sum of the scores and divide it by the number of tests. 435 ÷ 5 = 87.

  • 240 billion

  • 100 billion

  • 50 billion

  • 150 billion

Correct answer: 240 billion

By the end of President Clinton's second term in office, his economic policies had balanced the federal budget and created a surplus in the year 2000.

67.

How many 6-inch by 4-inch bricks are needed to build a walk 6 feet wide and 24 feet long?

  • 864

  • 432

  • 648

  • 76

Correct answer: 864

The width of the walk is 6 ft., or 6 x 12 = 72 in. The width of each brick is 4 in. The number of bricks that can be fitted along the width is 72 / 4 = 18. The length of the walk is 24 ft., or 24 x 12 = 288 in. The length of each brick is 6 in. The number of bricks that can be fitted along the length is 288 / 6 = 48. 18 x 48 = 864.

68.

Read the supporting details then correct the sentence below.

Sentences 3 and 4: When the dress code demands a certain attire to be worn. But how do you know what to wear?

Which of the following options best represents how the underlined portion of these sentences should be written?

  • worn, how

  • worn. But how

  • worn, and how

  • worn, or how

Correct answer: worn, how

Sentences 3 and 4 are sentence fragments, which can be corrected by replacing the period with a comma and eliminating the word “But.” When using a coordinating conjunction, such as “but,” the first part of your sentence needs to be an independent sentence. In this case, the first part of the sentence was not a complete thought; therefore, a coordinating conjunction (i.e. but, and, or) cannot be used to correct it.

69.

Read the supporting details then answer the following question.

Which of the following options initially limited the rights of African Americans after the United States’ Reconstruction Amendments were ratified?

  • Jim Crow laws

  • Brown v. Board of Education decision

  • Civil Rights Act of 1964

  • Voting Rights Act of 1965

Correct answer: Jim Crow laws

The Jim Crow laws initially limited the rights of African Americans after the United States’ Reconstruction Amendments were ratified. Although the United States tried to reconstruct the American South after the Civil War, the states instituted their own laws that limited the rights of African Americans. It was not until the Brown v. Board of Education decision, the Civil Rights Act of 1964, and the Voting Rights Act of 1965 that the full benefits of the Reconstruction Amendments were realized.

70.

An investor invests $12,000 in a mutual fund and earns 4.9% on the principle for each of five years. How much interest has accrued at the end of the period?

  • $2,940

  • $3,148

  • $2,805

  • $2,674

Correct answer: $2,940

To calculate interest earned over a period of time, you would use the formula I=PRT.

Interest equals principle ($12,000) times the rate of return (.049) times the length of time (5 years): (12,000)(.049)(5) = $2,940.

71.

Read the supporting details then answer the following question.

Which of the following options might describe Charles Mitchell’s opinion regarding the Stock Market Crash of 1929?

  • The stock market could have been saved if people would not have panicked

  • The stock market caused the Great Depression to occur

  • The government could have backed the stock market to keep it from crashing

  • The stock market is a financial risk that should not be taken

Correct answer: The stock market could have been saved if people would not have panicked

Charles Mitchell was a banker who tried to save the stock market by reassuring the country; therefore, he would not agree that the stock market is a financial risk that should not be taken. The passage states that the stock market crashed at the beginning of the Great Depression, but it did not indicate that Mitchell believed that it caused the depression to occur. The passage does not mention the government; therefore, you can eliminate that option. 

The passage does indicate that Mitchell believed that the stock market could be saved if the panic was reduced; therefore, the correct option is: The stock market could have been saved if people would not have panicked.

72.

Elizabeth works 12 hours per week and earns $10.50 per hour. 20% of her paycheck is taken for taxes and other withholdings. How much money does Elizabeth take home in a two-week period?

  • $201.60

  • $100.80

  • $126.00

  • $252.00

Correct answer: $201.60

First, calculate how much Elizabeth makes per week:

$10.50 per hour × 12 hours = $126 per week

Next, multiply that by 20% to account for withholdings.

$126 × 20%

$126 × 0.20 = $25.20 (weekly withholding)

Subtract withholdings from her weekly earnings.

$126 - $25.20 = $100.80

To find her income for two weeks, multiply by 2.

$100.80 × 2 = $201.60

73.

Brent measured the board at 8 3/4 feet. Shawn measured the same board at 6 1/2 feet. What is the difference between Brent's measurement and Shawn's measurement?

  • 2 1/4 feet

  • 3 feet

  • 2 1/3 feet

  • 1 2/3 feet

Correct answer: 2 1/4 feet

To find the difference, convert all mixed numbers to improper fractions.

8 3/4 = 35/4

6 1/2 = 13/2

Next, find a common denominator and subtract the numbers.

35/4 - (13/2)(2/2)

35/4 - 26/4 = 9/4 = 2 1/4 feet

8 3/4 - 6 2/4 = 2 1/4

You could also use the Bowtie method where you first need to convert the mixed numbers into improper fractions:

8 3/4 = 35/4, and 6 1/2 = 13/2

Then, 35/4 - 13/2 = (70 - 52) / 8 = 18/8 = 9/4 = 2 1/4.

74.

During the months of June and July, a town received 1 2/3 inches and 2 1/5 inches of rainfall respectively. If, in the month of October, the town received twice the difference of the two months, how much was the amount?

  • 1 1/15 inches

  • 8/15 inches

  • 1 7/15 inches

  • 4/15 inches

Correct answer: 1 1/15 inches

To find twice the difference of the two months, multiply the difference by 2.

2(2 1/5 - 1 2/3)

Change to improper fractions.

2(2 1/5 - 1 2/3)

2(11/5 - 5/3)

Next, find common denominators and subtract the fractions.

2(11/5 - 5/3) 

2[(11/5)(3/3) - (5/3) (5/5)]

2(33/15 - 25/15)

2(8/15) = 16/15, or 1 1/15

75.

Read the supporting details then answer the following question.

It can be inferred from this passage that igloos should be:

  • Constructed in cold climates

  • Used for ice-fishing huts

  • Built in the mountains

  • Insulated with animal skins

Correct answer: Constructed in cold climates

From the passage, you can infer that igloos should be constructed in cold climates. Igloos are made from snow blocks; therefore, you can determine that igloos would only last in climates that were cold. 

Igloos could be used for ice-fishing huts, but the passage does not indicate that they are used for fishing purposes. Igloos could be built in the mountains, but the passage does not mention or indicate that igloos should be built in the mountains. The passage states that animal skins are used for bedding or as a door covering, but it does not imply that they are used to insulate an igloo.

76.

Roselyn lost 4% after selling her used couch for $320. Find the original price of the couch.

  • $333

  • $336

  • $340

  • $342

Correct answer: $333

The original price of the couch is 100% of the selling price minus 4%.

100% - 4% = 96%, or 0.96.

Set up an equation to solve for the original cost, c.

320 = 0.96c

320 ÷ 0.96 = c

c = 333.33 = ~$333

77.

If a 100-watt light bulb is using a 220-volt power source, what current is being drawn?

  • 0.45 amperes

  • 2.2 amperes

  • 1.1 amperes

  • 0.90 amperes

Correct answer: 0.45 amperes

The equation to use to find the current is I = P/V (Power divided by the voltage equals the current). 100-watt / 220-volt = 0.45 approximate amperes.

78.

Read the supporting details then answer the following question.

According to the passage, what must you do in order for a magnetic compass to work appropriately?

  • Lay it completely flat

  • Point it toward the North Pole

  • Place it in water

  • Hold it vertically toward the sun

Correct answer: Lay it completely flat

In order for a magnetic compass to work appropriately, you must lay it completely flat. This answer is found in the last sentence of the second paragraph. 

The purpose of the compass is to show you what direction is north; therefore, you would not need to point it north in order for it to work. The passage does not state anything in regard to placing it in water or holding it toward the sun; therefore, those two options can also be eliminated.

79.

If Steven gets paid $2,000 each month, what is his yearly income after an annual tax reduction of 23%?

  • $18,480 after taxes

  • $15,520 after taxes

  • $20,480 after taxes

  • $21,700 after taxes

Correct answer: $18,480 after taxes

Find out how much Steven earns per year by multiplying his monthly salary by 12.

$2,000 × 12 = $24,000

Find 23% of $24,000 by converting 23% to a decimal and multiplying.

23% = 23/100 = 0.23

0.23 × $24,000 = $5,520

Since the question asks for Steven's income after taxes, subtract the taxes from his yearly salary.

$24,000 - $5,520 = $18,480 after taxes

Arrange the following fractions in descending order:

1/3, 2/5, 4/11, 3/7

  • 3/7, 2/5, 4/11, 1/3

  • 4/11, 3/7, 2/5, 1/3

  • 1/3, 2/5, 3/7, 4/11

  • 4/11, 2/5, 3/7, 1/3

Correct answer: 3/7, 2/5, 4/11, 1/3

To arrange the fractions, compare their values by first multiplying them by 100%.

  • 1/3 × 100% = 33.33%
  • 2/5 × 100% = 40%
  • 4/11 × 100% = 36.36%
  • 3/7 × 100% = 42.86%

Arrange the percentages from largest to smallest (descending order).

42.86%, 40%, 36.36%, 33.33%

Convert back to fractions.

3/7, 2/5, 4/11, 1/3
