• A. Hyperbole
• B. Oxymoron
• C. Simile
• D. Metaphor

Correct answer: B

Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.

2. What is the relationship between work and energy?

• A. Work is the rate of energy transfer
• B. Work and energy are the same concepts
• C. Work is the result of energy
• D. Work changes an object's energy from one form to another

Correct answer: d

Rationale: Work is the process that changes an object's energy from one form to another or transfers it from one object to another.

3. Which of the following terms refers to the abnormal sound heard during a stethoscope examination, potentially indicating a heart valve issue?

• A. Tachycardia
• B. Bradycardia
• C. Heart murmur
• D. Arrhythmia

Correct answer: D

Rationale: The correct answer is D: Arrhythmia. An arrhythmia refers to an irregular heart rhythm, which can manifest as abnormal sounds heard during a stethoscope examination. Tachycardia (A) and bradycardia (B) both pertain to heart rate abnormalities, with tachycardia indicating a fast heart rate and bradycardia a slow heart rate. However, these terms do not specifically relate to abnormal sounds. Heart murmur (C) is the term that refers to the abnormal sound heard during a stethoscope examination, potentially indicating a heart valve issue. Therefore, the correct answer is D as it best fits the description provided in the question.

4. The human body's largest organ, responsible for detoxification and a multitude of other functions, is the:

• A. Heart
• B. Liver
• C. Lungs
• D. Skin

Correct answer: B

Rationale: The correct answer is B: Liver. The liver is the largest internal organ in the human body and is responsible for detoxification, processing nutrients, producing bile, and regulating blood sugar levels, among other functions. While the heart is vital for pumping blood, the lungs are crucial for respiration, and the skin is the body's largest external organ, the liver plays a central role in detoxification and various metabolic processes, making it the correct answer to this question.

5. A solution is considered saturated when...

• A. More solute can be dissolved
• B. The solvent starts to evaporate
• C. The solution becomes cloudy
• D. It reaches a specific temperature

Correct answer: B

Rationale: The correct answer is B: 'The solvent starts to evaporate.' A solution is considered saturated when the solvent can no longer dissolve any more solute at a given temperature. When the solvent starts to evaporate, it means that the solution is becoming more concentrated and reaching its saturation point. This is a key indicator of a saturated solution. The other options do not accurately describe the concept of a saturated solution, making them incorrect choices.

6. What is the balanced chemical equation for the reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH)?

• A. H2SO4 + KOH → K2SO4 + H2O
• B. 2H2SO4 + 2KOH → 2K2SO4 + 2H2O
• C. H2SO4 + 2KOH → K2SO4 + 2H2O
• D. H2SO4 + 2KOH → K2SO4 + H2O

Correct answer: c

Rationale: The coefficients are adjusted to balance the number of atoms on both sides of the equation.
