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. What was the author's purpose in writing this passage about George Washington?

• A. To inform readers about Washington's advice and its relevance to modern times.
• B. To introduce George Washington as a historical figure.
• C. To emphasize that George Washington had a multifaceted role beyond being a military hero.
• D. To persuade readers that George Washington is a hero of liberty.

Correct answer: A

Rationale: The correct answer is A: 'To inform readers about Washington's advice and its relevance to modern times.' The passage focuses on Washington's advice, leadership, and legacy, particularly his farewell address, highlighting its significance in current times. This choice accurately reflects the primary purpose of the passage. Choice B is incorrect because the passage goes beyond mere introduction, delving into Washington's actions and beliefs. Choice C is incorrect as while the passage does mention Washington's multifaceted role, the primary focus is on his advice and legacy. Choice D is incorrect because the passage does not aim to persuade readers of Washington's heroism but rather inform them about his advice and principles.

3. What does the following sentence most nearly mean? 'The preparatory instars of such insects are aquatic; the adult instar is aerial.'

• A. The volume of water is necessary for preparing the insect for transition rather than the volume of the air.
• B. The insect's body is shaped like a star in both water and air.
• C. The stage of preparation between molting occurs in water, while the final stage happens in the air.
• D. These insects first breathe in water through gills and then continue to use the same organs to breathe in the air.

Correct answer: C

Rationale: The sentence indicates that the insects undergo different stages of development, with the preparatory instars being aquatic and the adult instar being aerial. This highlights the adaptability of these insects to different environments. Choice A is incorrect as it focuses on the volume of water and air rather than the stages of development in different environments. Choice B is unrelated to the content of the sentence and does not capture the meaning accurately. Choice D is incorrect as it specifically mentions breathing through gills, which is not explicitly stated in the sentence. Therefore, choice C is the best interpretation of the sentence.

4. How is this passage structured?

• A. cause and effect
• B. problem and solution
• C. chronological order
• D. compare and contrast

Correct answer: C

Rationale: The passage is structured in chronological order as it presents events in the order in which they occurred. It starts with Harriet Tubman's background as a slave, then progresses through her marriage, escape, and subsequent actions to help other slaves. Each event is presented in a time sequence, making it clear that the passage follows a timeline of events. Choices A, B, and D are incorrect because the passage does not focus on demonstrating cause and effect relationships, outlining problems and solutions, or comparing and contrasting different elements. Instead, it provides a historical account of Harriet Tubman's life in a sequential manner.

5. Which statement from the passage best supports the conclusion that taking notes and recording audio during an interview is a good practice for journalists?

• A. Journalists often use a recording device to capture the audio transcript of an interview with a subject.
• B. Relying on a recording device is not without troubles, however.
• C. As a result, a portion of an interview can be lost without any way to reclaim it.
• D. This dual-note method means that most of the time, a wise journalist has two good resources to use as he or she writes the article draft.

Correct answer: D

Rationale: The statement about the dual-note method best supports the conclusion that taking notes and recording audio is a good practice. It highlights the advantage of having two resources - notes and audio recordings - which provide comprehensive coverage of the interview. Choice A simply mentions the use of a recording device but does not emphasize the benefits of combining it with note-taking. Choices B and C focus on the limitations or potential issues with using recording devices, which do not promote the practice as positively as Choice D.
