1. What happens to the concentration of hydrogen ions (\([H^+]\)) in a solution as the pH increases?

• A. Increases
• B. Decreases
• C. Remains constant
• D. Becomes neutral

Correct answer: B

Rationale: As the pH increases, the concentration of hydrogen ions decreases. The relationship is inversely proportional

2. Certain medications can suppress the immune system to treat autoimmune diseases or prevent organ rejection after transplants. What is a potential risk associated with immunosuppressive drugs?

• A. Increased risk of developing allergies
• B. Increased susceptibility to infections
• C. Both a and b
• D. Neither a nor b

Correct answer: C

Rationale: The correct answer is C: 'Both a and b.' Immunocompromised individuals, who take immunosuppressive drugs, are at an increased risk of developing allergies due to the altered immune response. Additionally, these drugs suppress the immune system's ability to fight off infections, making individuals more susceptible to various pathogens. Therefore, both increased risk of developing allergies and increased susceptibility to infections are potential risks associated with immunosuppressive drugs, making option C the correct choice.

3. 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.

4. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?

• A. 1.4ml
• B. 2.1ml
• C. 2.8ml
• D. 3.5ml

Correct answer: D

Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.

5. A water wave approaches a shallow beach. What happens to its speed, wavelength, and frequency?

• A. Speed increases, wavelength decreases, frequency increases.
• B. Speed decreases, wavelength decreases, frequency remains the same.
• C. Speed increases, wavelength increases, frequency decreases.
• D. Speed, wavelength, and frequency remain the same.

Correct answer: B

Rationale: As waves enter shallow water, they slow down due to increased interaction with the bottom. This causes the wavelength to decrease to maintain the constant wave energy (E = hf). Frequency remains constant as it's determined by the source, not the medium.

6. What is the least common multiple (LCM) of 4 and 6?

• A. 24
• B. 12
• C. 6
• D. 3

Correct answer: B

Rationale: The LCM is the smallest number that is a multiple of both 4 and 6. We can find this by listing out the multiples of each number until we find a common value. In this case, 12 is the first number divisible by both 4 (4 x 3) and 6 (6 x 2).
