1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

• A. Wheezing
• B. Difficulty breathing
• C. Chest tightness
• D. Fever

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

3. What is the name of a condition where the immune system mistakenly attacks healthy body tissues?

• A. Allergy
• B. Autoimmune disease
• C. Immunodeficiency
• D. Sepsis

Correct answer: B

Rationale: The correct answer is B: Autoimmune disease. This condition occurs when the immune system mistakenly targets and attacks healthy tissues in the body, leading to inflammation and tissue damage. Autoimmune diseases can affect various organs and systems in the body, such as rheumatoid arthritis, lupus, and multiple sclerosis. Allergies (A) involve the immune system overreacting to harmless substances, but they do not involve attacking healthy tissues. Immunodeficiency (C) refers to a weakened immune system that is less able to fight off infections. Sepsis (D) is a life-threatening condition caused by the body's response to an infection, not an autoimmune reaction.

4. Which additional information would be MOST relevant to the passage's argument?

• A. A detailed biography of a historical figure with no analysis of their impact on society.
• B. A timeline of technological advancements throughout history with no connection to social consequences.
• C. A case study of how historical knowledge informed the development of a successful solution to a contemporary problem.
• D. A statistical analysis of economic trends without any reference to historical events or context.

Correct answer: C

Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.

5. What is the function of the pericardium, the sac surrounding the heart?

• A. o generate electrical impulses for heart contraction
• B. To transport blood throughout the body
• C. To provide lubrication for heart movement
• D. To protect the heart and anchor it in place

Correct answer: D

Rationale: The pericardium, the sac surrounding the heart, serves primarily to protect the heart and anchor it in place. It acts as a protective barrier against external infections or damage and helps to maintain the heart's position within the chest cavity. Additionally, the pericardium also provides some degree of shock absorption to minimize physical trauma to the heart. While the heart's electrical impulses for contraction originate from within the heart itself and are not generated by the pericardium, it does not play a role in directly generating these impulses. Therefore, option D, 'To protect the heart and anchor it in place,' is the correct function of the pericardium.

6. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.
