1. 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.

2. Which type of energy is associated with the random motion of particles in a substance?

• A. Potential energy
• B. Mechanical energy
• C. Thermal energy
• D. Chemical energy

Correct answer: c

Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.

3. The scientist discovered a new species of butterfly in the rainforest. What is the past tense of the verb "discover"?

• A. discovers
• B. discovered
• C. discovering
• D. discovery

Correct answer: B

Rationale: The past tense of a verb describes an action that happened in the past.

4. Which muscle type is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by a combination of voluntary and involuntary control, as the heart can beat involuntarily while also responding to signals from the autonomic nervous system. It is striated, meaning it has a striped appearance under a microscope due to the arrangement of contractile proteins. Cardiac muscle is responsible for pumping blood throughout the circulatory system, making it crucial for maintaining circulation and delivering oxygen and nutrients to tissues. Skeletal muscle (option A) is primarily under voluntary control and is responsible for movement, while smooth muscle (option B) is predominantly involuntarily controlled and found in organs like the intestines. Connective tissue (option D) provides support and structure but is not a muscle type responsible for pumping blood.

5. She decides to have a decentralized staffing system. Which of the following is an advantage

• A. greater control of activities
• B. Conserves time
• C. Compatible with computerization
• D. Promotes better interpersonal relationship

Correct answer: A

Rationale: The correct answer is A: 'greater control of activities.' Having a decentralized staffing system allows for the delegation of decision-making to lower levels of the organization, which can result in greater control over activities. This can lead to quicker responses to issues and better alignment with specific departmental needs. Options B, C, and D do not directly relate to the advantage of a decentralized staffing system. While conserving time, compatibility with computerization, and promoting better interpersonal relationships are important considerations in staffing decisions, they do not specifically align with the advantage of greater control that a decentralized system provides.

6. Which phenomenon describes the separation of light into its component colors when passing through a prism?

• A. Refraction
• B. Diffraction
• C. Dispersion
• D. Reflection

Correct answer: c

Rationale: Dispersion occurs when light passes through a prism, causing different wavelengths (colors) to separate due to their varying speeds through the medium.
