1. She tries to design an organizational structure that allows communication to flow in all

• A. Centralized
• B. Decentralized
• C. Matrix
• D. Informal

Correct answer: A

Rationale: The correct answer is 'A: Centralized.' In a centralized organizational structure, decision-making authority and communication flow through a single point of control or a specific group of individuals. This setup ensures that communication channels are streamlined and information is disseminated efficiently. By designing an organizational structure that allows communication to flow in all directions, it suggests a decentralized structure where decision-making authority is distributed across various levels and departments. Therefore, 'Centralized' is the best fit for the scenario described in the question.

2. In the context of the cardiac cycle, the P wave on an electrocardiogram (ECG) represents:

• A. Atrial depolarization
• B. Ventricular depolarization
• C. Atrial repolarization
• D. Ventricular repolarization

Correct answer: A

Rationale: The correct answer is A: "Atrial depolarization." The P wave on an ECG represents the depolarization of the atria, specifically the spread of electrical activity through the atria causing them to contract and push blood into the ventricles. This is the first wave observed on the ECG and signifies the beginning of the cardiac cycle. Ventricular depolarization is represented by the QRS complex, atrial repolarization is typically not visible on a standard ECG due to its timing with the QRS complex, and ventricular repolarization is represented by the T wave. Therefore, option A is the most appropriate choice in this context.

3. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

• A. Focuses on management tasks
• B. Is a caretaker
• C. Uses trade-offs to meet goals
• D. Inspires others with vision

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

4. Identify the type of error in the sentence "They went to the store, and bought groceries, then went home."

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The sentence combines two independent clauses without proper punctuation, forming a run-on sentence.

5. Which of the following describes a scalar quantity?

• A. Velocity
• B. Acceleration
• C. Force
• D. Speed

Correct answer: d

Rationale: Speed is a scalar quantity as it only indicates how fast an object is moving without any directional information.

6. What is the term for a solution that has exactly the same concentration of solute as another solution?

• A. Saturated solution
• B. Unsaturated solution
• C. Isotonic solution
• D. Concentrated solution

Correct answer: c

Rationale: An isotonic solution has the same concentration of solute as another solution. The other choices do not accurately describe an isotonic solution.
