1. Which word correctly completes the sentence: "He was _____ by the kindness of strangers."

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: "Effected" means to produce a result or impression, aligning with the emotional impact of the strangers' kindness.

2. Newton's rings are a visual demonstration of:

• A. Diffraction
• B. Doppler effect
• C. Polarization
• D. Thin-film interference

Correct answer: D

Rationale: Newton's rings are a series of concentric colored rings observed when light is reflected between a spherical surface and a flat surface. This phenomenon is a result of thin-film interference, which occurs due to the varying thickness of the air gap between the surfaces. The interference of light waves results in constructive and destructive interference, leading to the formation of the rings. Diffraction, the bending of light around obstacles, is not the cause of Newton's rings. The Doppler effect involves the change in frequency of waves due to motion and is not relevant in this context. Polarization refers to the orientation of electromagnetic waves, which is not the primary factor in the formation of Newton's rings. Therefore, the correct answer is D: Thin-film interference.

3. Which of the following is an example of a weak acid?

• A. Hydrochloric acid (HCl)
• B. Sulfuric acid (H2SO4)
• C. Acetic acid (CH3COOH)
• D. Nitric acid (HNO3)

Correct answer: C

Rationale: Weak acids only partially dissociate in water, releasing a lower concentration of hydrogen ions.

4. Which of the following is NOT a type of chemical bond?

• A. Ionic bond
• B. Covalent bond
• C. Metallic bond
• D. Gravitational bond

Correct answer: D

Rationale: Although gravity exists, it's not considered a chemical bond responsible for holding atoms together within molecules.

5. She is hopeful that her unit will make a big turnaround in the succeeding months. Which of

• A. Wonders why things are not what it used to be
• B. Finds solutions to the problems
• C. Integrate the solutions to his day-to-day activities
• D. Selects the best change strategy

Correct answer: C

Rationale: The correct answer is C: 'Integrate the solutions to his day-to-day activities.' In the given scenario, the individual is hopeful about a turnaround in their unit, indicating a desire for positive change. Option C aligns with this by suggesting that the individual is not only finding solutions to the problems (as in option B) but also integrating these solutions into their daily routines. This integration is crucial for sustained improvement and long-term success, making it the most appropriate choice among the options provided.

6. What is the primary function of the epiglottis in the respiratory system?

• A. Filtration of air
• B. Production of mucus
• C. Prevention of food entering the trachea
• D. Oxygen exchange in the alveoli

Correct answer: C

Rationale: The primary function of the epiglottis in the respiratory system is to prevent food from entering the trachea. When we swallow, the epiglottis covers the opening to the trachea, directing food and liquids to the esophagus instead of the airway. This action helps to protect the respiratory system from foreign objects that could obstruct airflow and cause choking or aspiration pneumonia. Filtration of air and production of mucus are functions associated with other respiratory structures like the nasal passages and bronchial tubes, while oxygen exchange in the alveoli occurs in the lungs, not the epiglottis.
