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. According to the passage, what effect does encountering an automobile with eighteen wheels have on the hypothesis 'All automobiles have only four wheels'?

• A. It proves the hypothesis.
• B. It raises the hypothesis's probability.
• C. It disproves the hypothesis.
• D. It decreases the hypothesis's probability.

Correct answer: C

Rationale: Encountering an automobile with eighteen wheels contradicts the hypothesis that all automobiles have only four wheels. This contradicts the initial hypothesis, proving it to be false. The passage explains that when evidence disproves a hypothesis, it directly contradicts the hypothesis, leading to its disproof. In the context of the monkey example provided, encountering a hairless monkey out of many hairy monkeys disproved the hypothesis 'All monkeys are hairy.' Therefore, the presence of an automobile with eighteen wheels disproves the hypothesis that all automobiles have only four wheels. Other choices are incorrect because encountering such an automobile directly contradicts the initial hypothesis, leading to its disproof, rather than proving it, raising its probability, or decreasing its probability.

3. According to the essay, how were stories first communicated and passed down?

• A. oral tradition
• B. printed books
• C. technology
• D. handwriting

Correct answer: A

Rationale: The essay clearly states that before the invention of the printing press, stories were passed down through oral tradition. The extract mentions, 'For centuries before the invention of the printing press, stories of the world were passed down to generations through oral tradition.' This shows that oral tradition was the primary method of communicating stories before the introduction of printed books. Therefore, the correct answer is 'oral tradition.' Printed books (choice B) were introduced later with the invention of the printing press, as mentioned in the extract. 'Handwriting' (choice D) is not the first way stories were communicated, and 'technology' (choice C) is a broad term that does not specifically refer to the initial method of story communication.

4. Which of the following is true about calcium-rich foods? I. Canned salmon with bones contains calcium. II. Cheese is a lactose-free food. III. Condensed soup made with water is a calcium-rich food.

• A. I only
• B. I and II only
• C. II and III only
• D. III only

Correct answer: A

Rationale: The correct answer is 'I only.' Canned salmon with bones contains calcium as the bones are a good source of calcium, making statement I true. However, statement II is false as cheese is not a lactose-free food. Statement III is also incorrect as condensed soup made with water is not necessarily a calcium-rich food. Other calcium-rich options include dairy products like milk, yogurt, and specific non-dairy products like calcium-fortified juices, canned fish with bones, soybeans, and leafy greens.

5. Which of the following would be the best concluding statement for this passage?

• A. States should consider the importance of foreign languages for the global economy when making policies regarding foreign language requirements for high school graduation.
• B. Policies for high school graduation should consider the significance of foreign languages for the global economy, college acceptance rates, and job opportunities.
• C. Influence of a second language on college acceptance rates warrants a foreign language class as a high school graduation requirement.
• D. The difficulty of obtaining a job in today’s economy without knowledge of multiple languages should be considered when setting foreign language requirements for high school graduation.

Correct answer: B

Rationale: Choice B provides the best concluding statement for this passage as it encapsulates the main argument and key supporting details presented in the extract. The passage emphasizes the importance of foreign languages for the global economy, the impact on college acceptance rates, and enhanced job opportunities for individuals proficient in more than one language. Choice B effectively summarizes these points, making it the most appropriate conclusion. Choices A, C, and D, while related to the main argument, only touch on one supporting detail each. Choice A focuses solely on the importance of foreign languages for the global economy, while choice C emphasizes the influence of a second language on college acceptance rates. Choice D highlights the difficulty of job acquisition without knowledge of multiple languages. These choices do not encompass the breadth of supporting details provided in the passage, making them less effective as concluding statements.
