1. "Ironic" and "serious" are:

• A. synonyms (have the same meaning)
• B. antonyms (have opposite meanings)
• C. homonyms (sound the same but have different meanings)
• D. none of the above

Correct answer: B

Rationale: "Ironic" means the opposite of "serious."

2. Which of the following is NOT a characteristic of a chemical reaction?

• A. Formation of new substances
• B. Release or absorption of energy
• C. Change in color
• D. Change in temperature

Correct answer: C

Rationale: While color change can be an indicator of a chemical reaction, it's not always present, and some reactions occur without a visible color change.

3. What property of matter determines its resistance to changes in shape or size?

• A. Solid
• B. Liquid
• C. Gas
• D. Plasma

Correct answer: B

Rationale: Liquids have a definite volume but can take the shape of their container, unlike solids with fixed shapes and volumes.

4. The human eye focuses light by adjusting the shape of its:

• A. Cornea
• B. Iris
• C. Lens
• D. Retina

Correct answer: C

Rationale: The human eye focuses light by adjusting the shape of its lens. The cornea is the transparent outer covering of the eye that helps to focus light, but it does not change shape. The iris regulates the amount of light entering the eye through the pupil but does not adjust the shape of the light. The retina is the layer at the back of the eye that receives and processes light signals but does not play a role in focusing light. Therefore, the correct answer is C, the lens, as it changes shape to focus light onto the retina, allowing for clear vision.

5. A closed system in ecology is one that:

• A. Exchanges energy but not matter
• B. Exchanges both energy and matter
• C. Exchanges neither energy nor matter
• D. Recycles nutrients efficiently

Correct answer: A

Rationale: Rationale: In ecology, a closed system is one that does not exchange matter with its surroundings but can exchange energy. This means that while energy can enter or leave the system, the amount of matter within the system remains constant. This definition aligns with option A, making it the correct answer. Options B and C are incorrect because a closed system does not exchange matter, and option D is not directly related to the definition of a closed system in ecology.

6. There are times when Katherine evaluates her staff as she makes her daily rounds. Which of

• A. The staff member is observed in natural setting.
• B. Incidental confrontation and collaboration is allowed.
• C. The evaluation is focused on objective data systematically.
• D. The evaluation may provide valid information for compilation of a formal report.

Correct answer: A

Rationale: The correct answer is A: 'The staff member is observed in a natural setting.' This option is the most appropriate because it aligns with the concept of naturalistic observation, where behavior is observed in its natural environment without interference or manipulation. In this scenario, Katherine is observing her staff during her daily rounds without any alterations to their behavior or environment. This allows for a more authentic and unbiased assessment of their performance. Options B, C, and D are not as relevant to the concept of naturalistic observation and do not accurately describe the situation presented in the question.
