1. 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.

2. Which term describes the resistance of a substance to flow?

A. Density
B. Viscosity
C. Conductivity
D. Malleability

Correct answer: b

Rationale: Viscosity refers to the resistance of a substance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.

3. What is the most effective way to ensure clarity and conciseness in your writing?

A. Using complex sentence structures and passive voice.
B. Avoiding unnecessary repetition and redundant words.
C. Replacing simple words with more sophisticated synonyms.
D. Adding flowery introductions and lengthy conclusions.

Correct answer: B

Rationale: Concise writing eliminates unnecessary words and uses active voice to express ideas directly and clearly.

4. What is the acceleration due to gravity near the Earth's surface?

A. 9.8 meters per second squared (m/sÃ‚Â²)
B. 6.3 meters per second squared (m/sÃ‚Â²)
C. 5.0 meters per second squared (m/sÃ‚Â²)
D. 12.5 meters per second squared (m/sÃ‚Â²)

Correct answer: a

Rationale: The acceleration due to gravity near the Earth's surface is approximately 9.8 m/sÃ‚Â²

5. The element responsible for the green color of leaves is:

A. Magnesium
B. Iron
C. Copper
D. Zinc

Correct answer: A

Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis

6. Which of the following is the primary function of the cell membrane?

A. To provide structural support for the cell
B. To transport substances in and out of the cell
C. To synthesize proteins and lipids
D. To store genetic material

Correct answer: B

Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.
