Which of the following is not a purpose of mitosis?
-
Produce eggs and sperm
-
Repair damaged tissue
-
Replace dead cells
-
Develop an individual

Which of the following is an example of a cartel formation?
-
Two local pharmacies decide to use price fixing in order to force out the chain drug store
-
A local pharmacy owner purchases all retail pharmacies in a 50-mile radius
-
A local pharmacy owner advertises his new lower prices on the radio
-
A local pharmacy traded merchandise with an out-of-town pharmacy
Correct answer: Two local pharmacies decide to use price fixing in order to force out the chain drug store

According to the graph, how much money was spent on loans?
-
$1,380
-
$780
-
$300
-
$2,340
Correct answer: $1,380
$1,380 was spent on loans. In order to find out how much was spent in any given category, multiply the total amount of income for the month, $6,000, by the percentage spent. Since 23% was spent on loans, we will multiply $6,000 x 0.23 = $1,380.

Samantha drives x miles the first day, y miles the second day, and z miles the third day. What is the average mileage covered per day?
-
(x + y + z)/3
-
x + y + z
-
(x/3) + (y/3) + (z/3)
-
(xyz)/3
Correct answer: (x + y + z)/3
To find the average, divide the total mileage by the total time.
Total distance = x + y + z
Total time = 3 days
Therefore, (x + y + z)/3 = average mileage covered per day.

Read the supporting details then correct the sentence below.
Sentence 5: One issue arising from suburban growth is the disorganized, reckless manner in who neighborhoods are built, called sprawl.
Which of the following changes should be made to correct sentence 5?
-
Change “who” to “which”
-
Change “are” to “is”
-
Change “suburban” to “Suburban”
-
Change “sprawl” to “Sprawl”
Correct answer: Change “who” to “which”
In order to correct sentence 5, you should change “who” to “which.” You would use “who” to refer an individual in an adjective clause and you would use “which” to refer to an object in an adjective clause. In this sentence, the object is “disorganized, reckless manner”; therefore, you would want to use “which” instead of “who.”
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 best describes the poem’s subject?
-
Ailing
-
Blessed
-
Irked
-
Energetic
Correct answer: Ailing
The poem is about an eighty-eight year old woman who is bedridden and is in much pain; therefore, you can infer that the woman’s health is ailing.
The poem does not indicate that the woman feels blessed or energetic, as she yearns for death and is in a lot of pain. You may have thought that the woman was irked, or upset, but the poem does not imply that the woman is mad.

Sentence 13: The TR07 has been tested extensively in Emsland Germany, and is the only high-speed maglev system in the world ready for revenue service.
Which of the following changes should be made to correct sentence 13?
-
Insert a comma after “Emsland”
-
Change “has been” to “had been”
-
Change “world” to “World”
-
Change “service” to “services”
Correct answer: Insert a comma after “Emsland”
In order to correct sentence 13, you should insert a comma after “Emsland.” You should always use a comma to separate items in an address, and in this case, you need to separate the state (“Emsland”) and the country (“Germany”) with a comma.
“World” is not a proper noun and does not need to be capitalized, unless it is used at the beginning of a sentence or in a title. The other answer options are not options that would make the sentence grammatically correct.

-
0.01 meters
-
1,000 millimeters
-
0.1 millimeters

A group of coworkers formed a team in order to motivate themselves to walk more often. Each week, they reported their total miles to their team captain. Last week, the following miles were recorded: 15, 22, 18, 8, 12, and x.
What would the value of x equal if the average number of miles recorded were 15 miles?
-
15 miles
-
13 miles
-
17 miles
-
18 miles
Correct answer: 15 miles
If the average is 15 miles, then (15 + 22 + 18 + 8 + 12 + x) ÷ 6 = 15.
Breaking down the steps, we solve for x:
- (75 + x) / 6 = 15
- (12.5 + x/6) = 15
- x/6 = 2.5
- x = 15 miles

Read the supporting details then correct the sentence below.
Sentence 10: Eukaryotes grow and reproduce through an process called mitosis.
Which of the following changes should be made to correct sentence 10?
-
Change “an” to “a”
-
Change “through” to “thru”
-
Change “reproduce” to “reproduced”
-
Change “process” to “processes”
Correct answer: Change “an” to “a”
As a rule, “an” should only be used before words that start with a vowel (i.e. a, e, i, o, and u) or before a word that contains an unpronounced “h” (i.e. hour). Therefore, “a” should be used before words that begin with a consonant (i.e. b, c, d, f, …). In this sentence, the next word after “an” starts with a consonant; therefore, “a” should be used.
“Through” and “thru” can be used interchangeably; therefore, it would not correct the sentence to change one to the other. Using “reproduced” would create a parallelism error. The sentence is only talking about one process (“mitosis”); therefore, you should not change the singular form of “process” to the plural form.

The diameter of one bicycle tire is 32 inches, and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel is 24 inches. What is the difference in inches between the length of the spokes of the two wheels?
-
4
-
12
-
8
-
6
Correct answer: 4
The spoke is equivalent to the radius, which is the diameter divided by 2. Therefore, the spoke for the 32-inch wheel is 16 inches. The spoke for the 24-inch wheel is 12 inches.
16 - 12 = 4-inch difference between the two spokes.

If five 4-ohm resistors are wired in a series into a 120-V power supply, what is the current that would flow through the circuit?
-
6 amp
-
12 amp
-
24 amp
-
30 amp
Correct answer: 6 amp
Ohm’s law states that the current equals the voltage divided by the resistance.
In this problem, you are given the voltage (120) and the resistance (4*5 = 20). Thus, the current equals 120 ÷ 20, or 6 amp.
