1. What type of writing is used in the passage?

• A. narrative
• B. persuasive
• C. expository
• D. technical

Correct answer: C

Rationale: The passage is expository because it presents information about 'The Five' group of Russian musicians and their contributions to classical music. It provides details about the background, works, and influence of each member of the group without telling a story, providing instructions, or attempting to persuade the reader. Choice A (narrative) is incorrect because the passage does not tell a story but rather presents factual information. Choice B (persuasive) is incorrect because the passage does not try to persuade the reader but instead informs about the musicians. Choice D (technical) is incorrect because the passage does not focus on technical details or procedures but rather on historical and musical information.

2. 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.

3. How does the author organize the passage?

• A. heading and subheadings
• B. superscripts
• C. diagrams
• D. labels and footnotes

Correct answer: A

Rationale: The author uses heading and subheadings to organize the passage. Each subheading focuses on either dairy (e.g., beverages, meals, snacks, dessert) or non-dairy options for obtaining more calcium from food. This organizational structure makes it easier for readers to identify and understand the different categories of tips provided within the text. Choices B, C, and D are incorrect because superscripts, diagrams, labels, and footnotes are not used as organizational features in the passage; instead, headings and subheadings play a key role in structuring the information.

4. Which definition best fits the word zymosis?

• A. Discontent
• B. An infectious disease
• C. Poverty
• D. Bad luck

Correct answer: B

Rationale: In this passage, the word 'zymosis' is described as a malady that the narrator has been suffering from since boyhood. This aligns with the definition of zymosis as an infectious disease, making option B the correct choice. Choices A, C, and D are incorrect because the passage clearly indicates that zymosis is a medical condition, not related to feelings of discontent, poverty, or bad luck.

5. 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.
