Which of the following numbers is the same as 6 1/4?
Correct Answer
E. 6.25
Explanation
The number 6 1/4 can also be written as a decimal by dividing the numerator (1) by the denominator (4), which equals 0.25. Therefore, the number that is the same as 6 1/4 is 6.25.
4.
Which of these four numbers is the largest?
Correct Answer
D. .25
Explanation
In comparing decimals, the value of each digit after the decimal point is examined starting from the left. The first non-matching digit determines the larger number. For .25 and .12, comparing hundredths shows that .25 (25 hundredths) is larger than .12 (12 hundredths). Therefore, .25, representing a quarter of a whole, is definitively larger than .12, or twelve hundredths of a whole.

Which of these words means intricate?
Correct Answer
A. Detailed
Explanation
The word "intricate" describes something that is highly complex or detailed. In a list of words that includes "detailed," "brave," "decorate," "accuse," and "courage," the word that best aligns with the meaning of intricate is "detailed." This is because "detailed" implies being filled with details and complexities, which matches the definition of intricate. The other options—brave, decorate, accuse, and courage—do not capture the complexity or detail-oriented nature that "intricate" suggests.

Without the use of compasses, what did the ancient Egyptians use to align the four sides of the Pyramid?
Correct Answer
A. Stars
Explanation
The ancient Egyptians used the stars, particularly the North Star, to align the sides of their pyramids with great precision. They observed the sky to determine true north and other cardinal directions. This astronomical method involved tracking the movement of stars across the night sky to establish a north-south line. They also employed other tools and methods, such as sighting rods and water-filled trenches, to ensure their constructions were accurately aligned. This attention to celestial objects and their use of rudimentary but effective tools allowed them to align the pyramids remarkably well with the cardinal points.

Correct Answer
E. Geology

Geology is the study of the earth's origin, history, and structure. It focuses on understanding the processes that have shaped the earth over millions of years, including the formation of rocks, minerals, and landforms. Geologists study the earth's layers, such as the crust, mantle, and core, and investigate the forces that have caused earthquakes, volcanic eruptions, and the movement of tectonic plates.

How _____________ sales did you make today?
Correct Answer
E. Many
Explanation
In English, when asking questions about the quantity of countable items, the word "many" is often used. In the context of the question "How many sales did you make today?" "many" is appropriate because sales are countable—meaning you can enumerate them one by one. The question is inquiring about the total number of sales transactions completed over a specific period, which in this case is today.
16.
Most of my co-workers have more experience __________________.
Correct Answer
C. Than me
Explanation
"Than" as a conjunction: When "than" is used as a conjunction (connecting two clauses), it's followed by a subject pronoun (I, he, she, they, we) in a full sentence. For example, "She is taller than I am."
"Than" as a preposition: In informal English, "than" can also act as a preposition. When it's a preposition, it's followed by an object pronoun (me, him, her, them, us).
In your sentence, "than" is acting as a preposition, so it needs the object pronoun "me".
17.

Explanation
The word "some" is the correct answer because it indicates an unspecified quantity of pens. It suggests that the person is open to having a few pens, without specifying a particular number.

Which device is considered the oldest time-telling device?
Correct Answer
C. Sundial
Explanation
A sundial is considered the oldest time-telling device because it uses the position of the sun to indicate the time. It consists of a flat plate with markings that indicate the hours, and a shadow-casting object called a gnomon. As the sun moves across the sky, the shadow cast by the gnomon moves along the markings, allowing people to determine the time of day. Sundials have been used for thousands of years and were widely used before the invention of mechanical clocks. They are still used today as decorative or educational objects.
22.
One of the cabinets ______________ open.
Correct Answer
B. Is
Explanation
In English, subject-verb agreement is a grammatical rule where the verb must be conjugated or modified so that it aligns in number (singular or plural) with the subject of the sentence. Since "one" is singular, the verb "is," which is the third person singular form of the verb "to be," is the appropriate choice. Using "is" indicates the state of being of the subject, in this case, that the cabinet is open. It’s specific to the condition of a single item (one cabinet) among potentially several, highlighting that while others might be closed, this particular one is not.
23.
The supervisor and her employees __________to the job fair.
Correct Answer
B. Went
Explanation
The correct answer is "went," as it correctly completes the sentence in the past tense, indicating that the supervisor and her employees attended the job fair in the past. "Will go" is future tense, "is" is present tense and singular (which doesn't match the plural subject), and "were" requires additional context. Therefore, "went" is the appropriate choice.

The correct answer is "It's" because it is a contraction of "it is," which is the correct verb form to use in this sentence.
