Which version of the underlined portion makes the sentence correct?

After writing the note to Jane and I, Robert made himself dinner and turned on the television.

  • Jane and me, Robert

  • Jane and I, Robert

  • Jane and myself, Robert

  • Jane, and I Robert

  • Jane, and me, Robert

Correct answer: Jane and me, Robert

The pronoun is one of the objects of the preposition of, so it should be the objective-case me, not the subjective-case I. The comma should be placed between the pronoun and Robert, because that's the point at which the introductory subordinate clause ends and the main independent clause begins.

The remaining answer choices are incorrect because they either use the subjective-case I rather than the objective-case me, contain misplaced commas, or use the reflexive verb myself where there is no need to do so.

102.

Elizabeth bought two pairs of shoes for $44.99 each, three dresses for $29.98 each, and a belt for $14.79. She then used a coupon for 10% off her entire purchase. How much did she pay in total?

  • $175.24

  • $194.71

  • $162.80

  • $157.44

  • $151.98

Correct answer: $175.24

1. Multiply each amount by the number of items Elizabeth bought.

$44.99 × 2 = $89.98

$29.98 × 3 = $89.94

$14.79 × 1 = $14.79

2. Add all of these totals together.

$89.98 + $89.94 + $14.79 = $194.71

3. Multiply the total by 10% to determine Elizabeth's discount.

$194.71 × 0.10 = $19.47

4. Subtract Elizabeth's discount from her total to find the amount she paid.

$194.71 - $19.47 = $175.24

103.

Dividing a number by 4 is the same as multiplying that number by:

  • 1/4

  • 1/2

  • 4

  • 2

  • 0.4

Correct answer: 1/4

If you select the number 20, and divide it by 4, the result is 5. If you multiply the number 20 by 1/4, the result is 5.

1/4 means 1 divided by 4.

104.

Jason can build 5 storage barns a week. Peter can build 7 storage barns a week. Jason and Peter receive an order for 180 storage barns. If they work together, how many weeks will it take Jason and Peter to complete the order?

  • 15 weeks

  • 12 weeks

  • 36 weeks

  • 26 weeks

  • 24 weeks

Correct answer: 15 weeks

Together, Jason and Peter can build 12 storage barns a week. Divide 180 storage barns by 12 storage barns a week, and you get 15 weeks.

105.

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

  • 2,645,280 minutes

  • 1,837 minutes

  • 44,088 minutes

  • 1,825 minutes

  • 110,220 minutes

Correct answer: 2,645,280 minutes

Start by finding the number of days in 5 years.

5 years * (365 days / 1 year) = 1,825 days

Add the 12 days.

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

Convert the number of days to hours.

1,837 days * (24 hours / 1 day) = 44,088 hours

Convert the number of hours to minutes.

44,088 hours * (60 minutes / 1 hour) = 2,645,280 minutes

John had his dog for 2,645,280 minutes when he had him for exactly 5 years and 12 days.

106.

Use the table of contents below to answer the question that follows.

A Textbook on Biology
1 - The Life of the Cell
2 - The Chemical Basis of Life
3 - The Molecules of Cells
4 - A Tour of the Cell
5 - The Working Cell
6 - How Cells Harvest Chemical Energy
7 - Photosynthesis
About the Authors
Glossary
Bibliography
Index

The reader wants to see what the word photosynthesis means. Where can the reader look to determine the definition the quickest?

  • Glossary

  • Index

  • Bibliography

  • About the Authors

  • Chapter 7

Correct answer: Glossary

The glossary of a textbook is where you can find a list of difficult or specialized words with their definitions; thus, the glossary would be the quickest method to determine the definition of photosynthesis.

107.

The stem-and-leaf plot shows student heart rates after doing 1 minute of jumping jacks.

What is the mode?

  • 99 beats/minute

  • 90 beats/minute

  • 115 beats/minute

  • 121 beats/minute

  • 154 beats/minute

Correct answer: 99 beats/minute

In a stem-and-leaf plot, the tens place is represented by the stem and the ones place is represented by the leaf. The mode is the number that appears most often. Because 99 appears three times, it is the mode.

  • 90 appears 0 times, so it is not the mode
  • 115 appears 0 times, so it is not the mode
  • 121 appears only 1 time, so it is also incorrect

108.

When the sum of 3.218 and 6.839 is rounded to the nearest tenth, the result is:

  • 10.1

  • 10.06

  • 10.0

  • 10.05

  • 10.2

Correct answer: 10.1

First, the answer must be rounded to the nearest tenth, so eliminate answer choices 10.06 and 10.05.

Next, add the two values together, but do not round yet. You are looking to round the sum, not the individual numbers. The equation: 3.218 + 6.839 yields a result of 10.057.

Now, you can round to the nearest tenth; the 5 digit in the hundredths place indicates that you need to round up. The correct answer is 10.1.

If you had rounded each number initially, the values would be 3.2 + 6.8, and the sum would be 10.0.

109.

The sentence below contains four portions that are identified with quotation marks. Read the sentence and determine which portion contains an error in diction, usage, idiom, or grammar.

That “specific” group of chickens “are” sometimes “referred to” as “feather dusters.”

  • Are

  • Specific

  • Referred to

  • Feather dusters

  • No error

Correct answer: Are

This sentence contains a subject-verb agreement error. The subject of the sentence is “group,” which is singular and requires the use of the singular verb “is,” not “are.” 

The other options are all appropriate uses of formal written English.

110.

Read the passage, then answer the following question.

Which of the following sentences represents an opinion of the author rather than a fact?

  • 9

  • 1

  • 3

  • 5

  • 7

Correct answer: 9

The statement “It is time to switch over to the reds” represents the feelings of the author, and would be difficult to prove. 

All other statements are facts.

111.

Darla makes $56,000.00 a year. Her company just announced that it is giving a 3.0% cash bonus to all of its employees, based on the employee's annual salary. How much will Darla's bonus be?

  • $1,680.00

  • $1,200.00

  • $1,600.00

  • $1,280.00

  • $1,480.00

Correct answer: $1,680.00

You will need to multiply to get the amount of Darla's bonus: $56,000.00 * 0.03 = $1,680.00.

112.

Simplify the following:

(x + 3)(x - 9)

  • x2 - 6x - 27

  • 3x2 - 9

  • x2 - 27

  • 2x2 - 6x - 6

  • 2x -6

Correct answer: x2 - 6x - 27

Use the FOIL (first, outside, inside, last) method.

1. Multiply x and x (first terms).

x * x = x2

2. Multiply x and -9 (outside terms).

x * -9 = -9x

3. Multiply 3 and x (inside terms).

3 * x = 3x

4. Multiply 3 and -9 (last terms).

3 * -9 = -27

4. Combine the terms.

x2 + -9x + 3x + -27

5. Simplify.

x2 - 6x - 27

113.

The sentence below contains four portions that are identified with quotation marks. Read the sentence and determine which portion contains an error in diction, usage, idiom, or grammar.

The teacher “overt” asked “that” the experiment be wrapped up on Friday, “frankly” requiring that his students stay after class “to finish.”

  • Overt

  • Frankly

  • That

  • To finish

  • No error

Correct answer: Overt

This sentence contains an adjective/adverb error. The adjective “overt” should be replaced with the adverb “overtly” to correctly modify the verb “asked.” 

The adverb “frankly” correctly modifies the verb “requiring,” and the prepositional phrase “to finish” is appropriately used.

114.

What is the circumference of a circle with a diameter of 6?

  • 18.84

  • 12.62

  • 15.06

  • 20.72

  • 16.52

Correct answer: 18.84

1. Find the radius.

Diameter = 2r

6 = 2r

r = 3

2. Find the circumference.

Circumference of a circle = 2πr

C = 2π(3)

C = 6π

C = 6(3.14) = 18.84

115.

Julie buys a car with power windows, air conditioning, and a sun roof. The car costs $20,000.00, and the options costs $500.00 each. Julie pays with a $22,000.00 check. Julie uses the following expression to calculate the amount of money she should receive back from the purchase:

$22,000.00 - ($20,000.00 + $500.00 + $500.00 + $500.00)

Which of the following expressions could Julie have also used?

  • $22,000.00 - $20,000.00 - 3($500.00)

  • 3 * ($22,000.00 - $25,000.00 - $500.00)

  • $20,000.00 + (3 * $500.00) - $22,000.00

  • $500.00 - $22,000.00 + $20,000.00

  • 3($22,000.00 - $500.00) + ($22,000.00 - $20,000.00)

Correct answer: $22,000.00 - $20,000.00 - 3($500.00)

If you solve the expression given to you, you have $22,000.00 - $21,500.00 = $500.00. Therefore, the correct expression needs to produce a value of $500.00.

The expression $22,000.00 - $20,000.00 - 3($500.00) = $500.00. This yields the same value as the given expression, so it is the correct answer.

116.

Read the passage and then answer the following question.

In this passage, initiatives most nearly means:

  • Proposals

  • Withdrawals

  • Refusals

  • Levels

  • Products

Correct answer: Proposals

Initiatives refers to strategies intended to improve a situation. Proposals are plans or suggestions, just as the National Farmer’s Alliance and Industrial Union had many suggestions for improving the farmers' situation. Proposals, therefore, is the best answer.

Withdrawals and refusals are near opposites of initiatives, so these answers are incorrect. Initiatives does not mean levels or products.

117.

Read the passage, then answer the following question.

Which of the following best describes the main point of the passage?

  • Pharmacists and nurses who work together can reduce hospital expenses and the risk of medication errors

  • Hospitals make too many medication errors

  • Hospital patients have daily medication regimens that need to be managed

  • Hospital patients do not provide information regarding their current medications, which causes medication errors to occur

  • Pharmacists and nurses work well together

Correct answer: Pharmacists and nurses who work together can reduce hospital expenses and the risk of medication errors

In the passage, the author discusses the need to reduce medication errors, the expense that the errors create, the harm to the patient, and the increase in the number of people with daily medication regimens. However, the author goes on to state how having pharmacists and nurses work together can help reduce these errors. This is the main point of the passage.

118.

Ken needs to increase his weekly pay to $248.00. Ken currently works 20 hours a week and earns $7.75 an hour. How many additional hours would Ken need to work in order to meet his goal of $248.00 per week?

  • 12

  • 10

  • 8

  • 14

  • 16

Correct answer: 12

First, you need to calculate the current amount of money that Ken earns per week. By multiplying 20 by $7.75, you find that Ken earns $155.00 per week.

To get to $248.00 per week, Ken needs to increase his weekly pay by $93.00.

Divide this total by his rate of $7.75 per hour, and you get the answer: 12 more hours.

119.

Read the passage, then answer the following question.

Which of the following best outlines the structure of the passage?

  • I. Research, II. Implications

  • I. Statement, II. Facts, III. Quotations

  • I. Theory, II. Facts, III. Examples

  • I. Question, II. Research, III. Answer

  • I. Quote, II. Statement, III. Facts

Correct answer: I. Research, II. Implications

The passage does not start with a question or a quote, so those answer choices can be eliminated. The passage does not end with a quote, so you can eliminate that answer choice. The passage does start with the research conducted and ends with the implications of the research done.

120.

Choose the option that best expresses the intended meaning of the quoted portion of the original sentence; this answer should use proper grammar, diction, sentence construction, and punctuation.

During the blizzard, road workers placed barrels along the “roads, and they thereby blocked them to all motorists.”

  • Roads, thereby blocking them to all motorists

  • Roads, and they thereby blocked them to all motorists

  • Roads, by which all motorists were therefore blocked

  • Roads and therefore blocking them to all motorists

  • Roads, and by which all motorists were now blocked

Correct answer: Roads, thereby blocking them to all motorists

The error with the original sentence is wordiness. The option “roads, thereby blocking them to all motorists” is the shortest and clearest option. 

The conjunction “thereby” is more precise than “therefore” when being used to refer to an event.
