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 source provides the best material for your assignment?

• A. It may be true that some businesses profit from buying up wetlands; however, the important point is that wetlands are disappearing. An ecologist noted that there are not enough private donors to buy these places.
• B. Greedy businesses are at the heart of the problem: they simply want to buy up cheap land to build and make money. They don't care about destroying our natural treasures. The physics professor noted that our town needs to buy this land.
• C. It's clear that wetlands are endangered; they are going to disappear unless we do something about it. We should get private donors to buy the land. An ecologist noted that wetlands are in danger.
• D. Businesses are part of the wetland problem. Without developers to buy them up, the town would not need to purchase the land to protect it. A physics professor noted that the wetland problem is related to greed.

Correct answer: C

Rationale: Source C provides the best material for the assignment because it emphasizes the importance of preserving wetlands, acknowledges the endangered status of wetlands, and suggests a solution involving private donors. The source highlights the crucial issue at hand - the disappearance of wetlands - and proposes a practical solution, making it a reliable and relevant source for an assignment on wetlands conservation. Choice A focuses more on the profit aspect rather than conservation. Choice B blames greedy businesses without offering a practical solution. Choice D discusses the relationship between businesses and wetlands but lacks a clear solution for conservation compared to Source C.

3. Assuming this statement is true, which of the answer choices is a logical conclusion?

• A. Whole language is more effective at teaching people to read than phonics.
• B. Phonics is more effective at teaching people to read than whole language.
• C. Literacy rates will probably continue to decline over the next 15 years.
• D. The definition of what it means to be literate is much stricter now.

Correct answer: B

Rationale: If we consider the information provided in the extract that literacy rates were higher when phonics was predominantly used and have declined since whole language programs became more popular, it logically follows that phonics is more effective at teaching people to read than whole language. Choice A is incorrect as the extract suggests the opposite. Choice C cannot be concluded based on the information provided; it is an assumption beyond the scope of the data. Choice D is also unrelated to the information given and does not logically follow from the provided statement.

4. What word best describes the organization of this passage?

• A. Modeling
• B. Hypothesizing
• C. Explaining
• D. Observing

Correct answer: C

Rationale: The correct answer is 'Explaining.' The passage is structured in an explanatory manner, providing a detailed account of how a plunger works. It explains the process step by step, from the initial depression of the plunger to the increase in pressure inside the clogged pipe. 'Modeling' and 'Observing' are not suitable choices as the passage does not involve creating models or direct observations. 'Hypothesizing' is also incorrect as the passage focuses on describing the functioning of a plunger rather than proposing or discussing potential hypotheses.

5. Which of the following statements would be LEAST relevant in a formal essay about artist Salvador Dalí?

• A. Although his works are famed for their dream-like qualities, Dalí executed them with realism reminiscent of the Renaissance masters.
• B. Salvador Dalí’s eccentricity extended beyond his artwork, affecting the strange public persona he created, which can be witnessed in his numerous television appearances.
• C. I’ve always found Dalí’s painting The Persistence of Memory to be really disturbing for some reason.
• D. Although Salvador Dalí is best known for his paintings, he also was active in cinema and collaborated with such filmmakers as Luis Bunuel and Alfred Hitchcock.

Correct answer: C

Rationale: Option C is subjective and personal, making it less suitable for a formal essay about Salvador Dalí. In formal writing, it is important to maintain objectivity and focus on factual information rather than personal opinions. Choices A, B, and D provide relevant information about Dalí, his artwork, and his collaborations, which are more appropriate for inclusion in a formal essay.
