1. 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.

2. Which of the following best describes the instructor's purpose in writing this email to his students?

• A. to berate students for the poor scores they received on the recent essay exam
• B. to encourage students to continue working hard despite failure
• C. to give students the opportunity to make up the bad score and avoid failing the course
• D. to admit that the essay exam was likely too difficult for most students

Correct answer: C

Rationale: The correct answer is C. The instructor's primary purpose in writing the email is to offer students the chance to make up the bad score they received on the recent essay exam, which was worth 70% of their final course score. The email does not berate students for their poor performance, nor does it admit that the exam was too difficult. While the instructor does offer encouragement to students who choose to complete an extra credit project, the main focus is on providing an opportunity to improve their scores and avoid failing the course.

3. Teddy has been assigned to write a history paper about the United States during the Cold War. What choice of three classes would likely be the most useful?

• A. 100, 300, 700
• B. 100, 300, 800
• C. 100, 400, 900
• D. 200, 300, 900

Correct answer: C

Rationale: Based on the Dewey Decimal System, which is a library classification system, the subjects related to Chomsky's work, which touches on philosophy, social sciences, and history, fall under classes 100, 400, and 900. Therefore, these classes would be the most useful for Teddy's history paper about the United States during the Cold War. Choices A, B, and D are incorrect because they do not include the specific classes related to the required subjects for Teddy's paper.

4. The author's purpose, major ideas, supporting details, visual aids, and vocabulary are the five key elements of what type of text?

• A. Fictional texts
• B. Narratives
• C. Persuasive texts
• D. Informational texts

Correct answer: D

Rationale: The author's purpose, major ideas, supporting details, visual aids, and vocabulary are key elements typically found in informational texts. Informational texts aim to inform and educate readers about a specific topic, which is why these elements are crucial for effectively conveying information in a clear and organized manner. Fictional texts focus more on storytelling and creativity rather than presenting facts and information, so they do not always include these specific elements. Narratives primarily focus on telling a story or recounting events, while persuasive texts aim to convince or sway the audience's opinion, so they may not always encompass all the elements mentioned in the question.

5. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to separate fact from fiction. Which of the following describes this type of writing?

• A. Narrative
• B. Persuasive
• C. Expository
• D. Technical

Correct answer: C

Rationale: Expository writing is used to explain or inform, as seen in the factual account of the Bermuda Triangle. The passage provides information to explain the phenomenon of the Bermuda Triangle, presenting facts and details without attempting to persuade or tell a story (narrative) or focusing on technical details. While the Bermuda Triangle has inspired many stories and theories, the passage aims to inform rather than persuade or delve into technical aspects.
