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 theme of the passage?

• A. Patronizing
• B. Skeptical
• C. Objective
• D. Nostalgic

Correct answer: C

Rationale: The correct answer is C: 'Objective.' The passage presents a factual account of Clara Barton's life events without showing bias or personal feelings. The text outlines significant milestones in Barton's life chronologically, from her birth to her contributions during and after the Civil War, culminating in her advocacy for the establishment of an American branch of the International Red Cross Organization. The passage does not exhibit a patronizing tone (choice A), as it does not talk down to Barton or belittle her achievements. It is also not skeptical (choice B), as it does not express doubt or disbelief in the information presented. Furthermore, the passage is not nostalgic (choice D), as it does not dwell on sentimental feelings or memories of the past. Therefore, 'Objective' is the most suitable description of the passage's theme.

3. Which of the following can the reader infer about the author's point of view when they state: 'the work Lamarr and Antheil did creating this frequency-hopping system led to many technologies that are often taken for granted today?'

• A. The author believes that we have underestimated the value of the contributions of lesser-known inventors
• B. The author believes that the frequency-hopping system has damaged the potential of modern electronics
• C. The author believes that the work of Lamarr and Antheil was instrumental to victory in World War II
• D. The author believes we spend too much time using technologies derived from...

Correct answer: A

Rationale: The author highlights the significance of the contributions made by lesser-known inventors like Lamarr and Antheil.

4. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

5. Which of the following best expresses the meaning of "intelligence (instinct)" in the context of this passage?

• C. Instinct is a natural ability to perform actions without learned behavior.
• D. Instinct refers to an animal's natural survival mechanism.

Correct answer: A

Rationale: Instinct refers to natural, unlearned behaviors, particularly in survival and reproduction.
