Question 6: Which of the following revisions best corrects the misplaced modifier in the sentence below? 'Sprinting across the field, the ball was caught by the receiver just before the touchdown.'
- Sprinting across the field, the receiver caught the ball just before the touchdown. (Correct answer)
- The ball, sprinting across the field, was caught by the receiver just before the touchdown.
- The ball was caught by the receiver sprinting across the field just before the touchdown.

Correct answer: Sprinting across the field, the receiver caught the ball just before the touchdown.
A misplaced modifier is a phrase that is not placed near the word it modifies, causing confusion. In the original sentence, it sounds like 'the ball' was sprinting. The modifier 'Sprinting across the field' should describe 'the receiver.' The correct revision places 'the receiver' immediately after the introductory modifying phrase. [16, 25, 33]

This oxygen is what most living organisms, including humans, need to breathe. Thus, not only does photosynthesis provide the energy base for most of the world's ecosystems, but it also supplies the oxygen we depend on. What is the author's primary purpose in writing this passage?
- To inform readers about the process and importance of photosynthesis. (Correct answer)
- To persuade readers to plant more trees.
- To entertain readers with a story about plants.
- To argue that photosynthesis is the only important biological process.

Our fathers are both engineers but they work at different companies. On Mondays, Selena has violin class and I have piano class. On Tuesdays and Thursdays, she practices volleyball at the school’s gym and I play tennis on our school court. Friday is my favorite day because Selena stays overnight with us.

Correct answer: The manager's responsibilities include hiring new employees, training staff, and creating the weekly work schedule.
Parallel structure requires that items in a list or series have the same grammatical form. The original sentence mixes a gerund ('hiring'), another gerund ('training'), and a noun phrase ('the creation of'). The correct revision uses the gerund form for all three items in the list: 'hiring,' 'training,' and 'creating'. [2, 17, 20]

Question 55: Read the following passage and answer the question. The giant panda, a bear native to south-central China, is characterized by its bold black-and-white coat and rotund body. Despite its classification in the order Carnivora, the panda's diet is over 99% bamboo. In the wild, pandas will occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents, or carrion. In captivity, they may receive honey, eggs, fish, yams, and specially formulated biscuits. The giant panda lives in a few mountain ranges in central China, mainly in Sichuan province, but also in neighboring Shaanxi and Gansu. As a result of farming, deforestation, and other development, the giant panda has been driven out of the lowland areas where it once lived. What is the main idea of this passage?
- Giant pandas are exclusively found in the Sichuan province of China.
- The giant panda is an endangered species due to habitat loss.

The passage discusses multiple aspects of the giant panda: its appearance ('black-and-white coat'), its primary and occasional diet ('over 99% bamboo' but also other foods), and its geographical location and habitat challenges ('mountain ranges in central China' and 'driven out of the lowland areas'). Therefore, the main idea is a general overview. The other options are too specific or are not fully supported by the text.

- The Alpha model has a larger screen than the Delta model.
- The Beta model is cheaper than the Delta model.
- The cheapest model has the shortest battery life. (Correct answer)
- The model with the smallest screen size is the most expensive.
Correct answer: The cheapest model has the shortest battery life.
By evaluating each statement against the table: The statement 'The cheapest model has the shortest battery life' is true because the Gamma model costs $699 (the lowest price) and has a battery life of 11 hours (the shortest duration). The other statements are false.
Question 60: Which of the following best describes how an igneous rock is formed?
- From the cooling and solidification of magma or lava. (Correct answer)
- From the compaction and cementation of layers of sediment.
- From the weathering and erosion of a mountain range.
- From the transformation of existing rock by heat and pressure.
Correct answer: From the cooling and solidification of magma or lava.
Igneous rocks are formed when molten rock (magma below the surface or lava above the surface) cools and hardens. Sedimentary rocks are formed from the compaction of sediment, and metamorphic rocks are formed by applying heat and pressure to existing rock.
Question 61: Which of the following values for 'x' is the correct solution for the equation 4x + 7 = 35?
- 5
- 9
- 7 (Correct answer)
- 10.5
Correct answer: 7
To solve for 'x', you must isolate the variable. First, subtract 7 from both sides of the equation: 4x = 35 - 7, which simplifies to 4x = 28. Next, divide both sides by 4: x = 28 / 4, which results in x = 7.

Question 65: From the list below, identify the word that is spelled INCORRECTLY.
- Occurrence
- Definately (Correct answer)
- Embarrass
- Recommend
Correct answer: Definately
The correct spelling is 'definitely.' A common error is to spell it with an 'a' ('definately'), likely due to its pronunciation. To remember the correct spelling, think of the root word 'finite.'
Question 66: A bar graph shows that Class A read 30 books and Class B read 45 books. How many more books did Class B read?
- 20
- 10

Question 69: In a classroom, the ratio of boys to girls is 3:5. If there are 15 girls in the classroom, how many boys are there?
- 9 (Correct answer)
- 25
- 8
- 12
Correct answer: 9
The ratio 3:5 means for every 5 girls, there are 3 boys. To find the number of boys for 15 girls, set up a proportion: 3/5 = x/15. Since 5 was multiplied by 3 to get 15, you must also multiply the corresponding number of boys (3) by 3. So, 3 × 3 = 9 boys.
Question 70: What is the area of a square with sides of 6 inches?
- 12 square inches
- 36 square inches (Correct answer)
- 18 square inches
- 24 square inches
Correct answer: 36 square inches
Area of a square = side × side = 6 × 6 = 36 square inches.
Question 71: Which of the following fractions is equivalent to 5/8?
- 15/32
- 20/24
- 25/40 (Correct answer)
- 10/18
Correct answer: 25/40
To find an equivalent fraction, you must multiply both the numerator and the denominator by the same non-zero number. For the correct answer, 5/8 is multiplied by 5/5: (5 × 5) / (8 × 5) = 25/40. The other options do not maintain this equivalency.
Question 72: Which sentence is the best topic sentence for a paragraph about the benefits of exercise?
- Regular exercise provides numerous physical and mental health benefits. (Correct answer)
- Some people do not like to exercise at all.
- Many people go to the gym every day.
- Exercise equipment can be expensive to purchase.
Correct answer: Regular exercise provides numerous physical and mental health benefits.

Question 74: A catering company needs to transport 248 dinner plates to an event. If each box can hold a maximum of 18 plates, what is the minimum number of boxes required to transport all the plates?
- 14 (Correct answer)
- 15
- 13.77
- 13
Correct answer: 14
To find the number of boxes, divide the total number of plates by the number of plates per box: 248 ÷ 18 = 13 with a remainder of 14. This means 13 boxes will be completely full, but there will be 14 plates left over. A separate box is needed for these remaining plates, so the total number of boxes required is 13 + 1 = 14.
Question 75: The line graph shows the average daily temperature for a city over a 5-day period. <pre> Day 1: 55°F Day 2: 60°F Day 3: 58°F Day 4: 65°F Day 5: 68°F </pre> Between which two consecutive days was the greatest increase in temperature?
- Day 3 and Day 4 (Correct answer)
- Day 2 and Day 3
- Day 1 and Day 2
- Day 4 and Day 5
Correct answer: Day 3 and Day 4
Calculate the temperature change between each pair of consecutive days: Day 1 to 2 (+5°F), Day 2 to 3 (-2°F), Day 3 to 4 (+7°F), and Day 4 to 5 (+3°F). The largest increase was 7°F, which occurred between Day 3 and Day 4.
Question 76: The development of Cuneiform, considered the earliest known system of writing, is a major contribution of which ancient civilization?
- Ancient Rome
- Ancient Mesopotamia (Sumerians) (Correct answer)
- Ancient Greece
- Ancient Egypt
Correct answer: Ancient Mesopotamia (Sumerians)

Question 79: A roller coaster car is stopped at the very peak of its highest hill. Which statement best describes the energy of the car at this moment?
- It has maximum kinetic energy and minimum potential energy.
- It has maximum potential energy and minimum kinetic energy. (Correct answer)
- It has equal amounts of potential and kinetic energy.
- It has no potential or kinetic energy.
Correct answer: It has maximum potential energy and minimum kinetic energy.
Potential energy is stored energy due to an object's position. At the highest point, the car has the most stored energy (maximum potential). Since it is stopped, its energy of motion (kinetic energy) is at a minimum.
Question 80: Which of the following sentences is grammatically correct and avoids a comma splice?
- The team practiced for hours, they were determined to win the championship.
- The team practiced for hours they were determined to win the championship.
- The team practiced for hours, determined to win the championship.
- The team practiced for hours, for they were determined to win the championship. (Correct answer)
Correct answer: The team practiced for hours, for they were determined to win the championship.
A comma splice occurs when two independent clauses are joined only by a comma. Choice C correctly fixes this by adding the coordinating conjunction 'for' after the comma, properly linking the two clauses. Choice A is a comma splice. Choice B is a fused sentence with no punctuation. Choice D is grammatically correct but changes the structure to a main clause followed by a participial phrase, which is a different way of correcting the initial error but C directly addresses the comma splice by adding a conjunction.
Question 81: A city ordinance states: 'All public parks shall be closed to the public between the hours of 10:00 PM and 6:00 AM. No individual shall enter, remain, or congregate in any public park during these hours. This rule does not apply to city employees performing official duties or to individuals who have obtained a special permit from the Parks Department for a nighttime event.' On a Tuesday at 11:00 PM, a group of friends is having a picnic in a public park. They do not have a permit. Which of the following is true according to the ordinance?
- The ordinance only applies on weekends, so the group is not in violation.
- Only the park rangers are allowed in the park at this time.
- The group is in violation of the ordinance. (Correct answer)
- The group is allowed to be in the park because picnics are a permitted activity.
Correct answer: The group is in violation of the ordinance.
The ordinance clearly states that parks are closed from 10:00 PM to 6:00 AM. The group is in the park at 11:00 PM without a special permit. Therefore, they are in violation of the rule against entering, remaining, or congregating in the park during closing hours.
Question 82: The table shows the team size for three projects, and the bar chart shows the percentage of tasks completed for each. Which project has the largest team size and has completed the smallest percentage of its tasks? <pre> Table: Project Team Size | Project | Team Size | |-----------|-----------| | Project A | 8 members | | Project B | 5 members | | Project C | 12 members| Chart: Percentage of Tasks Completed Project A: ████████████████ (75%) Project B: ██████████████████ (90%) Project C: ██████████ (50%) </pre>
- Project C (Correct answer)
- Project A
- Project B
- This cannot be determined from the data.
Correct answer: Project C
To answer this question, you must use information from both the table and the chart. According to the table, Project C has the largest team size (12 members). According to the bar chart, Project C has the lowest task completion rate (50%). Therefore, Project C fits both criteria.
Question 83: Which of the following words is an abstract noun?
- Tent

Question 88: A movie is 150 minutes long. How long is the movie in hours and minutes?
- 2 hours and 30 minutes (Correct answer)
- 3 hours
- 2 hours and 50 minutes
- 1 hour and 50 minutes
Correct answer: 2 hours and 30 minutes
There are 60 minutes in 1 hour. To convert 150 minutes to hours, divide 150 by 60. The result is 2 with a remainder of 30. This means the movie is 2 full hours and 30 minutes long.
Question 89: A popular new video game is released, and demand for it is extremely high. However, due to a manufacturing issue, the company can only produce a very limited number of copies. Based on the economic principle of supply and demand, what is the most likely immediate outcome?
- The company will halt all production of the game.
- The price of the game will decrease.
- The price of the game will increase. (Correct answer)
- The government will regulate the price of the game.
Correct answer: The price of the game will increase.
The law of supply and demand states that when demand for a product is high and the supply is low, the price will tend to rise. Because many people want the game but few copies are available, sellers can charge a higher price. A price decrease would happen if supply were high and demand were low. Government regulation and halting production are not direct outcomes of this specific supply-and-demand scenario.
Question 90: A train travels 60 miles per hour. How far will it travel in 3 hours?
- 120 miles
- 20 miles
- 180 miles (Correct answer)

Distance = speed × time = 60 miles/hour × 3 hours = 180 miles.
Question 91: Which sentence correctly uses a colon?
- The team's weaknesses were: a lack of communication and inconsistent practice.
- She visited three cities on her trip, London: Paris: and Rome.
- I have one primary goal for this summer: to learn how to code in Python. (Correct answer)
- The recipe required several ingredients; flour, sugar, eggs, and butter.
Correct answer: I have one primary goal for this summer: to learn how to code in Python.
A colon is used to introduce a list, explanation, or example, but it must follow a complete independent clause (a full sentence). Choice B is correct because 'I have one primary goal for this summer' is a complete sentence. Choice A incorrectly uses a semicolon. Choice C incorrectly places a colon after a verb ('were'), separating it from its objects. Choice D incorrectly uses colons to separate items in a simple list where commas should be used. [6, 8, 9]
Question 92: Which of the following is an example of a compound sentence?
- Running through the park, he tripped on a root.
- Because it was raining, the game was canceled.
- The tall oak tree stood beside the old barn.
- She studied hard, so she passed the test. (Correct answer)
Correct answer: She studied hard, so she passed the test.
A compound sentence joins two independent clauses with a coordinating conjunction (such as 'so'); 'She studied hard' and 'she passed the test' are both independent clauses.
Question 93: What does 'predict' mean?

Question 96: Read the sentence: 'The politician's speech was filled with equivocal statements, leaving the audience unsure of his true stance on the critical issue.' In the context of this sentence, what is the best definition for the word 'equivocal'?
- Passionate and inspiring
- Ambiguous and open to more than one interpretation (Correct answer)
- Clear and direct
- Angry and confrontational
Correct answer: Ambiguous and open to more than one interpretation
The key context clue is that the audience was 'unsure of his true stance.' This indicates that the statements were not clear. 'Ambiguous and open to more than one interpretation' is the only option that fits this context, as it explains why the audience would be left feeling uncertain.
Question 97: What is the meaning of the prefix 'un-' in the word 'unhappy'?
- Before
- Again
- Very
- Not (Correct answer)
Correct answer: Not
The prefix 'un-' means not, so unhappy means not happy.
Question 98: Solve the following expression: 3 + 2 x (6 - 1) ÷ 5
- 5 (Correct answer)
- 3
- 2
- 4
Correct answer: 5
Following the order of operations (PEMDAS/BODMAS): First, solve the parentheses (6 - 1) = 5. The expression becomes 3 + 2 x 5 ÷ 5. Next, perform multiplication and division from left to right: 2 x 5 = 10, then 10 ÷ 5 = 2. The expression is now 3 + 2. Finally, perform the addition: 3 + 2 = 5.
Question 99: Look at the pattern: △○△△○△△△○. How many triangles come before the next circle?
- 2
- 4 (Correct answer)
- 1

Question 101: A line graph shows temperatures rising from Monday to Friday. What conclusion can you draw?
- Temperatures stayed the same all week
- Temperatures increased over the week (Correct answer)
- Temperatures were highest on Monday
- Temperatures decreased over the week
Correct answer: Temperatures increased over the week
A rising line on a line graph indicates that the values being measured are increasing over time.
Question 102: An auditorium has 1,250 seats. For a school play, 78% of the seats were sold. How many seats were NOT sold?
- 22
- 125
- 275 (Correct answer)
- 975
Correct answer: 275
First, calculate the number of seats sold by finding 78% of 1,250: 0.78 * 1250 = 975 seats sold. Then, subtract the number of sold seats from the total number of seats to find the seats that were not sold: 1250 - 975 = 275.
Question 103: A carpenter has a piece of wood that is 10 1/2 feet long. He needs to cut a piece from it that is 3 2/3 feet long. After he cuts the piece, what is the length of the remaining wood?
- 6 5/6 feet (Correct answer)
- 6 1/2 feet
- 7 1/6 feet
- 7 1/3 feet
Correct answer: 6 5/6 feet
To subtract the mixed numbers, first find a common denominator for the fractions, which is 6. Convert 10 1/2 to 10 3/6 and 3 2/3 to 3 4/6. Since 3/6 is smaller than 4/6, you need to borrow from the whole number. 10 3/6 becomes 9 + 1 + 3/6 = 9 9/6. Now subtract: 9 9/6 - 3 4/6 = 6 5/6 feet.
Question 104: A student graphs points (1,2), (2,4), (3,6), and (4,8) on a coordinate plane. What pattern do these points show?
- The points form a circle
- The y-value equals the x-value
- The y-value is always double the x-value (Correct answer)
- The y-value is always less than the x-value
Correct answer: The y-value is always double the x-value
In each point, the y-value is exactly twice the x-value (2=2×1, 4=2×2, 6=2×3, 8=2×4).
Question 105: No word must ever leak out about this military action! It has to be a clandestine operation in order to succeed. Which word is a synonym of "clandestine"?

Correct answer: bear
Explanation: <br> Bear is the correctly spelled form of the animal.
Question 107: When adding the suffix '-ing' to the verb 'refer,' what is the correct resulting word structure and spelling?
- Referring, because the final syllable is stressed and ends in a single vowel followed by a single consonant. (Correct answer)
- Refereing, because the 'e' must be kept for pronunciation.
- Refering, because the base word ends in 'r'.
- Refering, because suffixes are added without changing the base word.
Correct answer: Referring, because the final syllable is stressed and ends in a single vowel followed by a single consonant.
The rule for doubling the final consonant when adding a suffix like '-ing' applies when a verb ends in a single vowel followed by a single consonant, and the final syllable is stressed. In 're-FER,' the last syllable is stressed, so the 'r' is doubled to make 'referring.' In a word like 'OF-fer,' the stress is on the first syllable, so the 'r' is not doubled ('offering').
Question 108: A student scored 85, 92, 78, and 89 on four science tests. What is the student's average (mean) score for these tests?
- 344
- 86 (Correct answer)
- 88
- 85
Correct answer: 86
To find the mean, you first add all the scores together (85 + 92 + 78 + 89 = 344). Then, you divide the sum by the number of scores (4). So, 344 ÷ 4 = 86.
Question 109: What is the correct use of a period in the following sentence?
- She had a bad day
- She had. a bad day.

Correct answer: She had a bad day.
Explanation: <br> She had a bad day. A period is only used at the end of a sentence, and not anywhere in between.
Question 110: Read the following paragraph and answer the question. Echolocation is a fascinating biological sonar used by several animal species, including bats, dolphins, and some shrews. These animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use the echoes to locate and identify the objects. The time it takes for the echo to return helps the animal determine how far away the object is. The direction from which the echo comes tells the animal the object's location. By interpreting these echoes, an animal can form a 'sound map' of its surroundings, allowing it to navigate and hunt in complete darkness. Based on the passage, which of the following can be inferred about animals that use echolocation?
- They are all nocturnal animals that are active only at night.
- They can function effectively in environments with little to no light. (Correct answer)
- They primarily live in caves and deep ocean environments.
- They have superior hearing capabilities compared to animals that do not use echolocation.
Correct answer: They can function effectively in environments with little to no light.
The passage explicitly states that echolocation allows an animal to 'navigate and hunt in complete darkness.' This directly supports the inference that these animals can function effectively in low-light or no-light conditions. While some may be nocturnal (like bats), the passage doesn't state they all are. Superior hearing is implied but not explicitly stated as a comparison. Their habitats are not limited to caves and oceans.
