• A. Law of Conservation of Matter

3. A new material is claimed to be stronger than steel. You design an experiment to test this claim. What is the MOST important control variable?

• A. The size of the material samples.
• B. The temperature at which the test is conducted.
• C. The force applied to the material.
• D. The color of the material.

Correct answer: A

Rationale: The size of the material samples is the most important control variable because it ensures that the comparison between the new material and steel is fair and accurate. By keeping the size consistent, any differences in strength can be attributed to the material composition rather than variations in sample size. Controlling for size helps eliminate confounding variables and increases the reliability of the experiment results. Temperature, force applied, and color are not as critical for directly testing the strength comparison between the new material and steel.

4. 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.

5. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

• A. sunset
