1. Which of the following minerals is important for bone health and is stored in bones by the skeletal system?

• A. Iron
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: C

Rationale: The correct answer is Calcium (Choice C). Calcium is essential for bone health and is stored in bones by the skeletal system. Bones act as a reservoir for calcium, playing a critical role in maintaining bone strength and density. Iron, sodium, and magnesium are important for various bodily functions but are not primarily stored in bones for bone health. Iron is crucial for oxygen transport, sodium helps regulate fluid balance, and magnesium is involved in over 300 enzymatic reactions in the body.

2. What is the purpose of the use of repetition in the following passage?

• A. It serves as a demonstration of Mr. Lanyon's mental state.
• B. It is reminiscent of the church bells mentioned in the story.
• C. It mimics Mr. Utterson's ambivalence.
• D. It emphasizes Mr. Utterson's anguish in failing to identify Hyde's whereabouts.

Correct answer: D

Rationale: The repetition in the passage, especially the reiteration of Mr. Utterson's struggle and the continuous digging at the problem, serves to emphasize Mr. Utterson's internal turmoil and anguish. It highlights his failure to identify Hyde's whereabouts and his increasing obsession with the mystery. Choice A is incorrect because the repetition does not primarily reflect Mr. Lanyon's mental state but focuses on Mr. Utterson's dilemma. Choice B is incorrect as the repetition does not directly relate to the church bells but to Mr. Utterson's persistent contemplation. Choice C is incorrect as the repetition does not specifically mirror Mr. Utterson's ambivalence but rather his distress and preoccupation with the problem.

3. How does the respiratory system facilitate gas exchange between air and blood?

• A. Diffusion
• B. Exhalation
• C. Inspiration
• D. Ventilation

Correct answer: A

Rationale: The correct answer is 'Diffusion.' Diffusion is the process by which gases are exchanged between air in the alveoli and blood in the capillaries. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli through diffusion. Exhalation is the process of expelling air from the lungs, inspiration is the process of inhaling air into the lungs, and ventilation refers to the overall movement of air in and out of the lungs. While these processes are essential for the respiratory system to function, they are not directly responsible for the gas exchange between air and blood, which is primarily achieved through diffusion.

4. Which of the following statements would be LEAST relevant in a formal essay about artist Salvador Dalí?

• A. Although his works are famed for their dream-like qualities, Dalí executed them with realism reminiscent of the Renaissance masters.
• B. Salvador Dalí’s eccentricity extended beyond his artwork, affecting the strange public persona he created, which can be witnessed in his numerous television appearances.
• C. I’ve always found Dalí’s painting The Persistence of Memory to be really disturbing for some reason.
• D. Although Salvador Dalí is best known for his paintings, he also was active in cinema and collaborated with such filmmakers as Luis Bunuel and Alfred Hitchcock.

Correct answer: C

Rationale: Option C is subjective and personal, making it less suitable for a formal essay about Salvador Dalí. In formal writing, it is important to maintain objectivity and focus on factual information rather than personal opinions. Choices A, B, and D provide relevant information about Dalí, his artwork, and his collaborations, which are more appropriate for inclusion in a formal essay.

5. Which term in physics describes the resistance of an object to changes in its motion?

• A. Inertia
• B. Momentum
• C. Gravity
• D. Kinetic energy

Correct answer: A

Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is explained by Newton's First Law of Motion, which states that objects tend to maintain their state of motion unless acted upon by an external force. Inertia is closely related to mass, where objects with more mass exhibit more resistance to changes in motion. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force of attraction between objects, and kinetic energy (D) is the energy associated with an object's motion. Therefore, the correct answer is A because inertia specifically addresses the resistance of an object to changes in its motion.
