1. The sentence 'The audience was captivated by the speaker's compelling story' implies that the audience:

• A. Was bored and disinterested.
• B. Found the story confusing.
• C. Was completely absorbed and engaged.
• D. Disagreed with the speaker's message.

Correct answer: C

Rationale: The term 'captivated' in the sentence indicates that the audience was completely engrossed and engaged by the speaker's compelling story. This implies that they were absorbed and highly interested in what was being presented. Choices A, B, and D are incorrect because 'captivated' suggests a positive and attentive reaction from the audience rather than boredom, confusion, or disagreement.

2. Through which structure do the kidneys reabsorb water, salts, and nutrients and return them to the body?

• A. Renal artery
• B. Renal vein
• C. Nephron
• D. Glomerulus

Correct answer: C

Rationale: The question has been corrected to specify the structure responsible for reabsorbing water, salts, and nutrients in the kidneys. The correct answer is the nephron, which is the functional unit of the kidney that performs filtration and reabsorption processes. The renal artery brings blood into the kidney for filtration, the renal vein carries filtered blood away from the kidney, and the glomerulus is a part of the nephron where filtration occurs. Therefore, the nephron is the structure that reabsorbs substances and returns them to the body.

3. Which type of blood cell is responsible for carrying oxygen?

• A. White blood cell
• B. Red blood cell
• C. Platelet
• D. Plasma

Correct answer: B

Rationale: The correct answer is B: Red blood cell. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues. They contain hemoglobin, a protein that binds to oxygen and transports it throughout the body. White blood cells (Choice A) are part of the immune system and help fight infections, not involved in carrying oxygen. Platelets (Choice C) are responsible for blood clotting, not oxygen transport. Plasma (Choice D) is the liquid component of blood that carries various substances like nutrients and waste products, but it does not directly carry oxygen.

4. What can one reasonably conclude from the final comment of this passage?

• A. The speaker is considering a name change.
• B. The speaker is experiencing an identity crisis.
• C. The speaker has mistakenly been looking for the wrong person.
• D. The speaker intends to continue to look for Hyde.

Correct answer: D

Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery. Choices A, B, and C are incorrect because there is no indication in the passage that the speaker is considering a name change, experiencing an identity crisis, or mistakenly looking for the wrong person. The passage focuses on Mr. Utterson's persistent search for Hyde, emphasizing his unwavering resolve.

5. Which of the following vessels is responsible for transporting blood from the heart to the lungs?

• A. Pulmonary vein
• B. Pulmonary artery
• C. Aorta
• D. Superior vena cava

Correct answer: B

Rationale: The correct answer is B, Pulmonary artery. The pulmonary artery carries deoxygenated blood from the heart's right ventricle to the lungs for oxygenation. This blood then undergoes the gas exchange process in the lungs, where carbon dioxide is removed, and oxygen is absorbed. The pulmonary vein, identified in choice A, carries oxygenated blood from the lungs back to the heart, which is the opposite direction of the blood flow specified in the question. Choice C, Aorta, is responsible for carrying oxygen-rich blood from the heart's left ventricle to the rest of the body, not to the lungs. Choice D, Superior vena cava, returns deoxygenated blood from the upper body to the heart's right atrium, but it does not transport blood specifically to the lungs as requested in the question.
