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. While researching Chomsky's Jewish heritage, Teddy wants to research traditional Judaism. Which section of the library would most likely contain the most relevant information?

• A. 100
• B. 200
• C. 300
• D. 900

Correct answer: B

Rationale: The correct answer is B: '200.' According to the Dewey Decimal System, religion falls under section 200. Traditional Judaism research aligns with religious studies, making section 200 the most suitable for finding relevant information. Choices A, C, and D do not directly relate to religious topics and are therefore less likely to contain information on traditional Judaism.

3. How does the author distinguish between different groups of insects mentioned in the passage?

• A. By describing the specific characteristics and adaptations of each insect group.
• B. By grouping them based on their habitat into aquatic and aerial categories.
• C. By explaining the stages of development each insect undergoes.
• D. By identifying their habitats and the environments they are adapted to.

Correct answer: B

Rationale: The author distinguishes between different groups of insects based on their habitat, categorizing them into aquatic and aerial categories. The passage mentions how some insects spend time under water while others live in the air, emphasizing the distinction between aquatic and aerial habitats. Therefore, choice B is correct. Choices A, C, and D are incorrect because the passage does not focus on describing the specific characteristics, adaptations, stages of development, or environments of the insects, but rather on their habitat and lifestyle.

4. Which detail from the passage best supports the conclusion that the little girl is no older than three years old?

• A. For lunch, she likes ham and cheese (torn into bites), yogurt, raisins, applesauce, peanut butter sandwiches in the fridge drawer, or any combo of these.
• B. It’s fine if you want to go somewhere, just leave us a note of where you are.
• C. As for nap, try after lunch. She may not sleep, but try anyway.
• D. Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep.

Correct answer: D

Rationale: The detail from choice D, 'Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep,' best supports the conclusion that the little girl is no older than three years old. This detail suggests that the child is still using a crib for sleeping, a common practice for infants and toddlers. Additionally, the mention of a bottle indicates that the child is likely young, as older children typically do not use bottles for sleep. Choices A, B, and C do not provide specific details related to the child's age like the mention of a crib and a bottle does in choice D.

5. 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.
