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. What is the main idea conveyed in the extract?

• A. Shia hears strange noises in the dark hallway
• B. Shia is working late at the office
• C. Shia is preparing for a presentation
• D. Shia encounters a terrifying situation in the CFO's office

Correct answer: D

Rationale: The main idea conveyed in the extract is that Shia encounters a terrifying situation in the CFO's office. The passage describes Shia hearing strange noises, feeling fear, and encountering alarming events like crashes and howls. This builds tension and indicates a dangerous situation unfolding. Choices A, B, and C are incorrect as they do not capture the central theme of Shia facing a frightening encounter in the CFO's office.

3. Which of the following statements offers a supporting argument for the passage's claim that many coastal islands are eroding?

• A. Recent hurricane seasons have been expensive.
• B. The Atlantic Basin is entering an active period.
• C. Louisiana has lost 2,000 square miles of coastal land.
• D. Barrier islands are the first line of defense against coastal storms.

Correct answer: C

Rationale: Statement C directly provides evidence of coastal land erosion by stating that Louisiana has lost a significant amount of coastal land area. This supports the passage's claim that many coastal islands are eroding. Choice A is incorrect because the expense of recent hurricane seasons does not directly relate to coastal land erosion. Choice B is incorrect as the active period of the Atlantic Basin does not specifically address coastal land erosion. Choice D, while related to coastal storms, does not directly support the claim that many coastal islands are eroding.

4. Which of the following guides would be the best for Raul?

• A. A Beginner's Guide to Giza (2015)
• B. The Life of Zahi Hawass (2014)
• C. A History of Hieroglyphics (2013)
• D. Who Built the Great Pyramids? (2015)

Correct answer: D

Rationale: The best guide for Raul would be 'Who Built the Great Pyramids?' as it focuses on the construction of the pyramids, providing detailed research on the topic. Choices A, B, and C are less relevant as they do not specifically address the construction of the pyramids. Choice A is about Giza in general, Choice B is a biography, and Choice C is about hieroglyphics, none of which directly relate to the construction of the pyramids.

5. What role do the spiracles play in the respiration of the insects described in the passage?

• A. They allow insects to breathe atmospheric air even when submerged.
• B. They protect the insect's internal organs from water pressure.
• C. They filter oxygen from the water for underwater breathing.
• D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.
