1. Which of the following is an opinion, rather than a historical fact, expressed by the author?

• A. Leif Erikson was definitely the son of Erik the Red.
• B. Leif Erikson's crew called the land Vinland.
• C. Leif Erikson deserves more credit for his accomplishments.
• D. Leif Erikson explored the Americas nearly five hundred years before Columbus.

Correct answer: C

Rationale: The statement 'Leif Erikson deserves more credit for his accomplishments' is an opinion rather than a historical fact. Historical facts can be verified through evidence and documentation, while opinions are subjective viewpoints. Choices A, B, and D provide historical facts about Leif Erikson's lineage, the name given to the land he discovered, and his exploration, respectively, which can be supported by historical records and research.

2. Which of the following is a chief difference between evaporation and boiling?

• A. Liquids boil only at the surface, while they evaporate equally throughout the liquid.
• B. Evaporating substances change from liquid to gas, while boiling substances change from gas to liquid.
• C. Evaporation can happen below a liquid's boiling point.
• D. Evaporation happens in nature, while boiling is a man-made phenomenon.

Correct answer: C

Rationale: The chief difference between evaporation and boiling is that evaporation can happen below a liquid's boiling point, while boiling only occurs at the liquid's boiling point. Evaporation is the process of a liquid turning into a gas at any temperature, while boiling specifically refers to the rapid vaporization that occurs when a liquid reaches its boiling point. Choice A is incorrect because liquids evaporate throughout the liquid, not just at the surface. Choice B is incorrect as evaporating substances change from liquid to gas, while boiling substances change from liquid to gas. Choice C is incorrect as boiling is not a man-made phenomenon; in fact, it is a natural process based on temperature changes. Choice D is incorrect because evaporation can happen naturally and is not limited to man-made processes.

3. Identify the INCORRECT function of the liver.

• A. Bile production to aid digestion.
• B. Synthesis of blood proteins, such as albumin.
• C. Storage of glucose for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

4. What is the term for the process of breaking a large molecule into smaller fragments by applying heat?

• A. Polymerization
• B. Hydrogenation
• C. Isomerization
• D. Pyrolysis

Correct answer: D

Rationale: Pyrolysis is the correct answer. It is the process of breaking down large molecules into smaller fragments by applying heat in the absence of oxygen. This results in the decomposition of molecules into simpler compounds. Polymerization, the process of synthesizing large molecules from smaller units, is incorrect as it is the opposite process. Hydrogenation involves adding hydrogen atoms to a compound, usually with a catalyst, which is not related to breaking down large molecules. Isomerization refers to rearranging atoms within a molecule to form isomeric compounds with the same molecular formula but different structural arrangements, which is also unrelated to the process described in the question.

5. Which of the following best summarizes the central theme of Wilde's play?

• A. The absurdity of the British aristocracy and its social conventions.
• B. The importance of being sincere and honest in personal relationships.
• C. The dual nature of social standing and the conflicts it creates.
• D. The challenges of maintaining personal integrity in a hypocritical society.

Correct answer: A

Rationale: The correct answer is A: 'The absurdity of the British aristocracy and its social conventions.' The central theme of Wilde's play, as revealed through satire, is the critique of the absurdities and trivialities of the British aristocracy. Wilde uses clever dialogue, puns, and irony to expose the superficiality and hypocrisy of the upper classes. While sincerity and honesty in personal relationships are explored in the play, they are not the central theme. Choice C, the dual nature of social standing and resulting conflicts, is a partial theme but not the central one. Choice D, the challenges of maintaining personal integrity in a hypocritical society, touches on a theme present in the play, but it is not as central as the critique of the British aristocracy's absurdities and social conventions.
