1. According to the essay, how were stories first communicated and passed down?

• A. oral tradition
• B. printed books
• C. technology
• D. handwriting

Correct answer: A

Rationale: The essay clearly states that before the invention of the printing press, stories were passed down through oral tradition. The extract mentions, 'For centuries before the invention of the printing press, stories of the world were passed down to generations through oral tradition.' This shows that oral tradition was the primary method of communicating stories before the introduction of printed books. Therefore, the correct answer is 'oral tradition.' Printed books (choice B) were introduced later with the invention of the printing press, as mentioned in the extract. 'Handwriting' (choice D) is not the first way stories were communicated, and 'technology' (choice C) is a broad term that does not specifically refer to the initial method of story communication.

2. Which organelle provides energy for cellular functions?

• A. Nucleus
• B. Cell membrane
• C. Mitochondria
• D. Cytoplasm

Correct answer: C

Rationale: The correct answer is C, Mitochondria. Mitochondria are often referred to as the powerhouse of the cell as they produce energy in the form of ATP through cellular respiration. This process is essential for various cellular functions, making mitochondria crucial for energy production within the cell. Choice A, Nucleus, is incorrect as the nucleus is responsible for housing the cell's genetic material and controlling cellular activities but not for energy production. Choice B, Cell membrane, is incorrect as it is primarily involved in maintaining cell integrity and regulating the passage of substances in and out of the cell, not in energy production. Choice D, Cytoplasm, is incorrect as it is the jelly-like substance that fills the cell and is the site of many metabolic pathways, but it is not the specific organelle responsible for energy production.

3. 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.

4. Which of the following is important to do while writing the first draft of a research paper?

• A. Listen to soothing music to create a relaxed writing environment.
• B. Write the conclusion before writing the rest of the research paper.
• C. Write the introduction, the body, and the conclusion of the project.
• D. Check to ensure that all citations are accurate.

Correct answer: C

Rationale: When writing the first draft of a research paper, it is crucial to include the complete structure, which consists of the introduction, body, and conclusion. This approach helps in organizing your thoughts and ideas cohesively, ensuring that your paper flows logically. Choice A is not directly related to the drafting process. Choice B suggests an incorrect sequence by proposing to write the conclusion first, which should actually be crafted after the body of the paper. Choice D is important but typically done during the editing and revision stages rather than in the initial draft.

5. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

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

Correct answer: A

Rationale: According to Newton's second law of motion, acceleration is directly proportional to the force acting on an object when the mass is constant. Therefore, if the force acting on an object is increased while the mass remains constant, the acceleration of the object will also increase. This relationship is described by the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration. When force increases, acceleration increases, and vice versa, as long as the mass stays the same. Choice B (Acceleration decreases) is incorrect because acceleration and force have a direct relationship. Choice C (Acceleration remains constant) is incorrect because acceleration changes in response to changes in force. Choice D (Acceleration becomes zero) is incorrect because increasing force does not make acceleration zero; it actually increases it.
