1. What is the absolute value of -7?

• A. 49
• B. 17
• C. 7
• D. 14

Correct answer: A

Rationale: Absolute value refers to the non-negative distance of a number from zero. Regardless of being positive or negative, 7 is its distance from zero.

2. Electrons occupy specific energy levels around the nucleus, but not in fixed orbits. This concept is captured by the:

• A. Bohr model
• B. Quantum mechanical model
• C. Lewis structure
• D. Octet rule

Correct answer: B

Rationale: Quantum mechanical model. Unlike the Bohr model with its defined electron paths, the quantum mechanical model uses probability distributions to describe electron locations within energy levels.

3. Which blood type is a universal donor?

• A. A
• B. B
• C. AB
• D. O

Correct answer: D

Rationale: Rationale: Blood type O is considered the universal donor because individuals with type O blood can donate red blood cells to individuals with any ABO blood type (A, B, AB, or O) without causing an adverse reaction. This is because type O blood lacks A or B antigens on the surface of red blood cells, which helps minimize the risk of an immune response when transfused into individuals with different blood types. Therefore, type O blood is in high demand for blood transfusions in emergency situations when the recipient's blood type is unknown or when there is a shortage of specific blood types.

4. When proofreading your writing, focus on:

• A. Changing the wording to sound more original.
• B. Ignoring minor grammatical errors like typos.
• C. Checking for clarity, consistency, and overall flow.
• D. Replacing common words with thesaurus alternatives.

Correct answer: C

Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.

5. Define the term "momentum" in physics.

• A. Force exerted on an object
• B. Speed of an object in motion
• C. Mass in motion
• D. Distance traveled per unit time

Correct answer: c

Rationale: Momentum is the product of an object's mass and velocity, describing its motion and resistance to changes in motion.

6. Percent (%) is a way to express a fraction with a denominator of 100. 125% can be expressed as a fraction in lowest terms. Which of the following represents 125% as a fraction?

• A. 5/4
• B. 1/8
• C. 5/2
• D. 25/2

Correct answer: A

Rationale: Percent literally means "out of one hundred." So, 125% is equivalent to 125/100. We can simplify this fraction by dividing the numerator and denominator by 25, resulting in 5/2.
