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. What is the SI unit of measurement for momentum?

• A. Newton (N)
• B. Kilogram-meter per second (kg·m/s)
• C. Joule (J)
• D. Newton-second (N·s)

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).

3. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

• A. Look for elements with similar atomic weights
• B. Identify the group number, which often indicates the typical ionic charge
• C. Identify the group number, which often indicates the typical ionic charge
• D. Analyze the element's position within the period

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table.

4. What is the primary function of the coronary arteries in the cardiovascular system?

• A. Carry oxygenated blood to the heart muscle
• B. Carry deoxygenated blood from the heart muscle
• C. Pump blood to the lungs for oxygenation
• D. Regulate blood pressure in the systemic circulation

Correct answer: A

Rationale: The primary function of the coronary arteries in the cardiovascular system is to carry oxygenated blood to the heart muscle. These arteries supply the heart muscle with the necessary oxygen and nutrients it needs to function properly. Without adequate blood flow through the coronary arteries, the heart muscle can become deprived of oxygen, leading to conditions like angina or even a heart attack. Options B, C, and D are incorrect as they do not accurately describe the function of the coronary arteries. Option B is incorrect because the coronary arteries carry oxygenated blood, not deoxygenated blood. Option C is incorrect because the pulmonary arteries, not the coronary arteries, carry blood to the lungs for oxygenation. Option D is incorrect because the regulation of blood pressure in the systemic circulation is primarily controlled by mechanisms such as the kidneys and the autonomic nervous system, not the coronary arteries.

5. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."

• A. "My biggest fear"
• B. "that I wouldn't live life to the fullest"
• C. "life"
• D. "the fullest"

Correct answer: B

Rationale: Option B functions as the object of the verb "is," making it a noun clause.

6. Which of the following organs is NOT directly involved in the mechanical breakdown of food?

• A. Mouth
• B. Stomach
• C. Small intestine
• D. Esophagus

Correct answer: D

Rationale: The correct answer is D, esophagus. The esophagus is a muscular tube that connects the mouth to the stomach, but it is not directly involved in the mechanical breakdown of food. The mouth is responsible for the initial mechanical breakdown of food through chewing, the stomach further breaks down food through muscular contractions, and the small intestine aids in the digestion process. However, the esophagus primarily serves to transport chewed food from the mouth to the stomach via peristaltic movements, without actively breaking down the food itself.
