1. What property of a substance refers to its ability to be drawn into thin wires without breaking?

• A. Malleability
• B. Viscosity
• C. Ductility
• D. Conductivity

Correct answer: C

Rationale: Ductility is the property that allows a substance to be drawn into thin wires without breaking. Malleability, on the other hand, is the ability to be hammered or rolled into thin sheets. Viscosity is the measure of a fluid's resistance to flow. Conductivity, lastly, refers to a substance's ability to conduct electricity or heat. Therefore, in this context, the correct answer is ductility as it specifically relates to the ability of a substance to be drawn into thin wires without breaking.

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

• A. To 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: C

Rationale: The pericardium is a double-walled sac that surrounds the heart and contains a small amount of fluid to provide lubrication for the movement of the heart within the chest cavity. It helps reduce friction as the heart beats and moves. Choice A is incorrect because the generation of electrical impulses for heart contraction is primarily the function of the heart's specialized conduction system. Choice B is incorrect as the pericardium is not involved in the transportation of blood throughout the body. Choice D is also incorrect as while the pericardium does protect the heart, its primary function is to provide lubrication and reduce friction.

3. The athlete ran the race in record time. Which word is the present participle of the verb 'run'?

• A. ran
• B. runs
• C. running
• D. runner

Correct answer: C

Rationale: The present participle form of a verb is used to indicate continuous or ongoing action. In this case, 'running' is the present participle of the verb 'run.' It shows that the action is in progress, unlike the past tense 'ran' or the simple present 'runs.' 'Runner' is a noun derived from the verb but not the present participle form.

4. Which of the following correctly lists the normal blood flow through the heart?

• A. Left ventricle, left atrium, body, right ventricle, right atrium, lungs
• B. Left atrium, left ventricle, lungs, right atrium, right ventricle, body
• C. Right atrium, right ventricle, lungs, left atrium, left ventricle, body
• D. Right ventricle, right atrium, body, left atrium, left ventricle, lungs

Correct answer: B

Rationale: The correct order of normal blood flow through the heart is as follows: from the body, blood flows into the right atrium, then to the right ventricle, followed by the lungs through the pulmonary artery for oxygenation. Oxygenated blood then returns to the heart through the pulmonary veins into the left atrium, then moves into the left ventricle before being pumped out to the body. Choice B correctly depicts this sequential flow of blood through the heart. Choices A, C, and D are incorrect as they do not follow the typical path of blood flow through the heart.

5. In which of the following materials would the author be most likely to include this passage?

• A. A history textbook
• B. An obituary
• C. A fictional story
• D. A newspaper editorial

Correct answer: A

Rationale: A history textbook is the most appropriate place for the passage about George Washington because it provides historical context, factual information, and analysis of significant events related to his life and contributions. The passage discusses Washington's role in the American Revolution, his leadership during the Revolutionary War, his decision to step down after the war, his farewell address, and his views on governance and foreign affairs. This type of detailed historical content is commonly found in history textbooks. Choices B, C, and D are incorrect because an obituary focuses on a person's death and life achievements in a brief manner, a fictional story is based on imagination and creativity, and a newspaper editorial typically presents opinions on current events or issues rather than historical accounts.
