1. The athlete ran the race in record time. Which word is the present participle of the verb "run"?

• A. ran
• B. runs
• C. running
• D. runner

Correct answer: C

Rationale: The present participle form of a verb describes an ongoing action.

2. The term "magic number" in nuclear physics refers to specific numbers of protons or neutrons that contribute to:

• A. Increased nuclear instability
• B. Enhanced radioactive decay rates
• C. Exceptional stability of the nucleus
• D. All of the above

Correct answer: C

Rationale: The term "magic number" in nuclear physics refers to specific numbers of protons or neutrons that result in exceptional stability of the nucleus. When the number of protons or neutrons in a nucleus align with a magic number, the nucleus is more stable and less likely to undergo spontaneous radioactive decay. This stability is due to the arrangement of nucleons within the nucleus, leading to lower energy states and increased binding energy. Magic numbers play a crucial role in determining the overall stability and behavior of atomic nuclei. Therefore, the correct answer is C: "Exceptional stability of the nucleus."

3. Which of the following is a redox reaction?

• A. 2H2 + O2 → 2H2O
• B. Zn + 2HCl → ZnCl2 + H2
• C. 2NaCl → 2Na + Cl2
• D. CH4 + 2O2 → CO2 + 2H2O

Correct answer: b

Rationale: The oxidation state of Zn changes from 0 to +2, indicating a redox reaction.

4. Which nitrogenous bases pair with each other in DNA?

• A. A-G and T-C
• B. A-T and C-G
• C. -A and T-T
• D. C-C and G-G

Correct answer: B

Rationale: Rationale: In DNA, nitrogenous bases pair with each other in a specific manner known as complementary base pairing. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This pairing is essential for maintaining the structure and function of DNA. Therefore, option B is the correct answer as it correctly identifies the nitrogenous bases that pair with each other in DNA.

5. The process of a gas changing directly into a solid is called:

• A. Condensation
• B. Deposition
• C. Sublimation
• D. Evaporation

Correct answer: B

Rationale: This process, also known as sublimation, involves gas particles losing energy and transitioning directly into the solid state.

6. Julius orients his staff on the patterns of reporting relationship throughout the organization.

• A. Span of control
• B. Hierarchy
• C. Esprit d’ corps
• D. Unity of direction

Correct answer: B

Rationale: The correct answer is B: Hierarchy. Hierarchy refers to the structure of authority and responsibility within an organization, including the levels of management and the reporting relationships. In this scenario, Julius is orienting his staff on the patterns of reporting relationships, which is a key aspect of hierarchy. Span of control refers to the number of employees a manager can effectively supervise, esprit de corps pertains to team spirit and unity among employees, and unity of direction relates to ensuring all activities are focused on the same objectives. Therefore, the most appropriate term for Julius's action is hierarchy.
