1. What can the reader infer from this passage? I would sometimes lie down, and let five or six of them dance on my hand; and at last the boys and girls would venture to come and play at hide-and-seek in my hair.

• A. The children tortured Gulliver.
• B. Gulliver traveled to meet new people.
• C. Gulliver is considerably larger than the children playing around him.
• D. Gulliver has a genuine love and enthusiasm for people of all sizes.

Correct answer: C

Rationale: The correct answer is C. The reader can infer from the passage that Gulliver is considerably larger than the children playing around him. This is evident from the fact that the children dance on his hand and play hide-and-seek in his hair, indicating a significant size difference between Gulliver and the children. Choice A is incorrect because there is no mention or implication of the children torturing Gulliver in the passage. Choice B is incorrect because Gulliver's reason for traveling is not mentioned in the provided excerpt. Choice D is incorrect as there is no explicit indication of Gulliver having a genuine love and enthusiasm for people of all sizes; the passage primarily focuses on the interaction between Gulliver and the children in terms of size and playfulness.

2. Which structure in the heart is responsible for pumping oxygenated blood to the body?

• A. Right ventricle
• B. Left ventricle
• C. Left atrium
• D. Right atrium

Correct answer: B

Rationale: The left ventricle is the chamber responsible for pumping oxygenated blood from the heart to the body. It receives oxygen-rich blood from the left atrium and contracts to push this blood out to the rest of the body through the aorta. The right ventricle pumps deoxygenated blood to the lungs for oxygenation, making choices A, C, and D incorrect for this function. Therefore, the correct answer is B, the Left ventricle.

3. What happens to the potential energy of an object as it falls freely near the Earth's surface?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: A

Rationale: As an object falls freely near the Earth's surface, its potential energy decreases. This decrease occurs because the gravitational potential energy is being converted into kinetic energy as the object accelerates due to gravity. According to the law of conservation of energy, the total mechanical energy (the sum of potential and kinetic energy) remains constant in the absence of non-conservative forces like air resistance. Choice B ('Potential energy increases') is incorrect because the object's potential energy is being converted into kinetic energy, leading to a decrease. Choice C ('Potential energy remains constant') is incorrect as the conversion of potential energy to kinetic energy results in a decrease in potential energy. Choice D ('Potential energy becomes zero') is incorrect because potential energy is not reduced to zero but is transformed into kinetic energy as the object falls.

4. Which of the following describes a graph that represents a proportional relationship?

• A. The graph has a slope of 2,500 and a y-intercept of 250
• B. The graph has a slope of 1,500 and a y-intercept of -150
• C. The graph has a slope of 2,000 and a y-intercept of 0
• D. The graph has a slope of -1,800 and a y-intercept of -100

Correct answer: C

Rationale: A graph that has a y-intercept of 0 indicates a proportional relationship because the starting value is 0, and no amount is added to or subtracted from the term containing the slope. In this case, choice C is correct as it has a y-intercept of 0, which aligns with the characteristics of a proportional relationship. Choices A, B, and D have non-zero y-intercepts, indicating a starting value other than 0, which does not represent a proportional relationship.

5. What is the most common cause of aseptic meningitis?

• A. Bacteria
• B. Viruses
• C. Fungi
• D. Parasites

Correct answer: B

Rationale: Aseptic meningitis is typically caused by viral infections, such as enteroviruses (e.g., coxsackievirus, echovirus), herpes simplex virus, varicella-zoster virus, and others. These viruses can infect the meninges, leading to inflammation and symptoms of meningitis without the presence of bacteria. While bacterial meningitis is a serious and life-threatening condition, aseptic meningitis caused by viruses is usually less severe and has a better prognosis. Fungi and parasites are less common causes of meningitis compared to bacteria and viruses.
