If the United States could encourage its citizens to recycle 50 percent of the plastic bottles manufactured, how many total pounds of plastic bottles would be recycled?
-
947,000 pounds
-
992,819 pounds
-
627,456 pounds
-
673,275 pounds
Correct answer: 947,000 pounds
If the United States could encourage its citizens to recycle 50 percent of the plastic bottles manufactured, they would recycle a total of 947,000 pounds (1,894,000 x 50% = 947,000).
If you thought the answer was 992,819 pounds, it is important that you read the question and compare it to the data, as the question was not asking you for an additional amount that would be recycled, it was asking you for 50 percent of the total manufactured pounds.

Solve:
(3/4) - (2/5)
-
7/20
-
1/5
-
1/1
-
4/5
Correct answer: 7/20
To solve this question, we must first change both fractions to have the same denominator. To do this, we look for the lowest common multiple between the denominators, which in this case is 20. Now, we must change each fraction to have a denominator of 20:
- 3/4 becomes 15/20
- 2/5 becomes 8/20
Solve:
15/20 - 8/20 = 7/20
Since the denominators are the same, we just need to subtract the numerators and keep the same denominator.
7/20 is the answer as this cannot be reduced further.

Nora is buying a necklace that costs $6. Sales tax is 7 1/4 cents per dollar. How much will Nora pay in sales tax on her purchase?
-
$0.44
-
$0.88
-
$1.62
-
$0.24
Correct answer: $0.44
To find sales tax, first convert the fraction to a decimal percent: 7 1/4 percent = 0.0725. Next, multiply the amount of the purchase by the tax rate: $6 multiplied by 0.0725 = $0.44.

A pipe can supply 25 cubic centimeters of water to a tank in one second. How long will the pipe take to fill a 2000-liter tank?
-
80,000 seconds
-
800 seconds
-
8,000 seconds
-
80 seconds
Correct answer: 80,000 seconds
1 liter = 1,000 cubic centimeters
1 liter × 2,000 = 1,000 cubic centimeters × 2,000 = 2,000,000 cubic centimeters
If 25 cubic centimeters is supplied in one second, 2,000,000 cubic centimeters will be supplied in 2,000,000/25 seconds.
2,000,000/25 = 80,000 seconds

-
Insert a comma after “Mindfulness”
-
Replace “its” with “it’s”
-
Change “will be” to “would be”
-
Change “for the” to “of the”
Correct answer: Insert a comma after “Mindfulness”

Which of the following changes should be made to correct sentence 6?
-
Remove the comma after “Because”
-
Insert a comma after “of land”
-
Change “are” to “were”
-
Change “desire” to “desires”
Correct answer: Remove the comma after “Because”
In order to correct sentence 6, you should remove the comma after “Because.” You should use a comma after the conjunctive adverb “because” if it is following a transitional phrase. However, when the subordinating conjunction “Because” is used at the beginning of a sentence, it does not require the use of a comma after it.
The other answer options are not options that would make the sentence grammatically correct.
110.
The government has a road construction contract where 280 miles are to be paved. If the contractor has so far completed 180 miles, what percentage of the road is remaining on the contract?
-
36%
-
64%
-
56%
-
46%
Correct answer: 36%
The length of the road on contract = 280 miles
The completed section = 180 miles
The remaining section = 280 - 180 = 100 miles
To find the percentage of the road remaining, divide 100 by 280 and multiply by 100 to find a percentage.
100/280 × 100% ≅ 36%

Read the supporting details then correct the sentence below.
Sentence 9: However, consider that trees bring energy savings by moderating heat in commercial areas, and that landscaping with trees increase property values.
Which of the following changes should be made to correct sentence 9?
-
Change “increase” to “increases”
-
Remove the comma after “However”
-
Remove the comma after “areas”
-
Insert a comma after “savings”
Correct answer: Change “increase” to “increases”
In order to correct sentence 9, you would need to change “increase” to “increases.” The plural verb “increase” is referring to the singular subject “landscaping”; therefore, the verb also needs to be singular (“increases”).
The comma after “However” and “areas” are correct, as commas are used to set off interjections and interruptions. The insertion of a comma after “savings” would cause a grammatical error.
112.

-
Insert a comma after “Furthermore”
-
Replace “quality;” with “quality,”
-
Change “absorb” to “absorbs”
-
Change “improve” to “improved”
Correct answer: Insert a comma after “Furthermore”
In order to correct sentence 6, you would need to insert a comma after “Furthermore.” A comma should be used to set off interjections and interruptions; therefore, it is necessary to place a comma after the interjection (“Furthermore”).
The use of a semicolon after “quality” is appropriate, as it is being used to join two independent clauses. The other answer options are not options that would make the sentence grammatically correct.
113.
Write the following as an equation:
The sum of a certain number and twice the same number equals the product of 3 and 7.
-
2n + n = 3 × 7
-
2n = 10 + n
-
n = 2n + 10
-
2n = n + 3 + 7
Correct answer: 2n + n = 3 × 7
Let n be the number. Twice that number is 2n. Therefore, the sum of the number and twice that number is 2n + n.
"Equals the product of 3 and 7" means that 3 and 7 will be multiplied after the equal sign.
2n + n = 3 × 7

-
Change “main street” to “Main Street”
-
Change “that” to “which”
-
Change “compare” to “compares”
-
Change “benefits” to “benefit”
Correct answer: Change “main street” to “Main Street”
In order to correct sentence 3, you would need to change “main street” to “Main Street.” The names of streets, roads, and highways are capitalized; therefore, “Main Street” should be capitalized.
The other answer options are not options that would make the sentence grammatically correct.

Read the supporting details then answer the following question.
Which of the following options best explains how the washboard is currently being used?
-
As a musical instrument
-
As a washing machine
-
As a piece of artwork
-
As a magic act
Correct answer: As a musical instrument
The passage informs you that the festival is used to showcase the washboard’s musical attributes, and that the washboard company changed their mission to bolster support for washboard musicians.
You can eliminate “as a washing machine,” because today’s electric-powered washing machines have replaced the washboard. Washboards may be used as artwork or as a magic act, but this is not implied in the given passage; therefore, you can eliminate them as options.

Increase 97 by 23%.
-
119.31
-
122.31
-
120
-
121
Correct answer: 119.31
To increase 97 by 23%, first, convert 23% to a decimal and then multiply by 97.
23% = 23/100 = 0.23
0.23 × 97 = 22.31
Then, add this to the original value of 97.
97 + 22.31 = 119.31

Read the supporting details then answer the following question.
If enough of the endangered trees were replanted in order to classify them as threatened instead of endangered, how many total threatened tree species would there be?
-
4,435
-
1,705
-
5,200
-
2,470
Correct answer: 4,435
This environmental question can be answered simply by adding. If enough of the 235 endangered tree species being replanted were replanted, and they were now classified as threatened, there would be a total of 4,435 threatened tree species (4,200 threatened tree species + 235 replanted endangered tree species = 4,435).

A school has 27 classes with 9 students in each class. In order to reduce the class size to 6 students per class, how many new classes must be formed?
-
14
-
7
-
41
-
6
Correct answer: 14
There need to be 14 new classes formed. The number of students in the school is 27 x 9 = 243. If there are to be no more than 6 students in a class, the number of classes needed is 243/6 = 40.5. We will round up to 41, since there is no such thing as half a class.
Therefore, the number of new classes needed is 41 - 27 = 14.

Which of the following options best describes what “bitumen” is?
-
A natural sticky black substance
-
A man-made asphalt material
-
A concrete mortar
-
A brick-making skill
Correct answer: A natural sticky black substance
According to the passage, bitumen is a natural sticky black substance. This answer is found in the sixth sentence of the passage’s first paragraph.
Bitumen is used in asphalt, but it is not the asphalt itself. The Sumerians used bitumen like a mortar for their brick roads, but it is not a concrete mortar.
