• A. At the nanoscale, metals are rigid, and at larger scales, they are bendable.
• B. Matter has different and special characteristics at the nanoscale.
• C. At the nanoscale, matter has different properties than matter at the atomic level.
• D. There is no difference.

Correct answer: B

Rationale: The correct answer is B. Matter at the nanoscale exhibits unique and special characteristics that distinguish it from matter at larger scales. This can include properties like increased surface area, different melting points, altered conductivity, and enhanced reactivity. Choice A is incorrect as metals at the nanoscale can be more rigid compared to their larger scale counterparts. Choice C is incorrect because matter at the nanoscale has properties that are distinct from both atomic and larger scales. Choice D is incorrect as there are significant differences in how matter behaves and interacts at the nanoscale compared to larger scales.

2. What is the author’s primary purpose in writing this essay?

• A. To persuade
• B. To entertain
• C. To analyze
• D. To reflect

Correct answer: A

Rationale: The author’s enthusiastic and supportive tone toward yoga—stating that it is an exercise that "everyone should try"—indicates a clear intent to persuade the audience about the benefits of yoga.

• A. The heart regulates oxygen flow and waste disposal, with the kidneys aiding in salt and water absorption.
• B. The cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys.
• C. Baroreceptors send impulses to regulate blood pressure by affecting the heart, arteries, and veins.
• D. Chemoreceptors monitor oxygen levels to impact blood pressure.

Correct answer: B

Rationale: The correct answer is B because it provides a comprehensive summary of the passage, explaining how the cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys. Choice A is incorrect as it only focuses on the heart and kidneys without mentioning the broader cardiovascular system. Choice C is incorrect as it solely emphasizes the role of baroreceptors in regulating blood pressure. Choice D is incorrect as it oversimplifies the role of chemoreceptors in monitoring oxygen levels without mentioning their impact on blood pressure regulation.

4. What is the meaning of the word "pulses" as it appears in the first paragraph?

• A. The regular throbbing of the arteries caused by successive contractions of the heart
• B. The general attitude of the public or a specific population toward health concerns
