1. What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches?

• 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 meaning of the word 'popular' as it is used in the third paragraph?

• A. complicated
• B. old-fashioned
• C. beloved
• D. for the general public

Correct answer: D

Rationale: In the context provided, 'popular' refers to magazines intended for the general public. The paragraph mentions that Infotrac indexes hundreds of popular magazines and newspapers, including medical journals such as the Journal of the American Medical Association and New England Journal of Medicine. These magazines target a wide audience, making choice D ('for the general public') the correct answer. Choices A, B, and C are incorrect as they do not align with the context of the paragraph.

3. In the passage the word embark means to:

• A. Remove the covering from a tree
• B. Speak harshly to others
• C. Entertain the reader
• D. Put or go on board a ship

Correct answer: D

Rationale: The word 'embark' typically means to board a ship or begin a journey. In this context, it means to start or set out on a new undertaking or venture, often including the act of boarding a ship. In the provided passage about the Golden Gate Bridge, it is mentioned that builders, architects, and workers embarked on the challenge of building a bridge across the Golden Gate Strait, which refers to them starting this new undertaking. Therefore, the correct definition of 'embark' is D. Put or go on board a ship. The other choices are incorrect: A. Removing the covering from a tree is unrelated to the context of the passage. B. Speaking harshly to others and C. Entertaining the reader are also irrelevant to the meaning of 'embark' in this context.

4. What is the main idea of the passage about microbes?

• A. Recent discoveries are revealing the critical role of microorganisms in maintaining a properly functioning immune system.
• B. The human body is host to a staggering number of microorganisms.
• C. Bacteriotherapy reintroduces healthy bacteria into a colon lacking the capability to defend against pathogenic agents.
• D. Early research has shown remarkable discoveries in the possibilities of bacteriotherapy.

Correct answer: A

Rationale: The main idea of the passage is that recent discoveries are shedding light on the pivotal role of microorganisms in maintaining a properly functioning immune system. The passage discusses how the human body hosts a wide array of microorganisms, emphasizes the importance of these bacteria in the development of the immune system, and explores the potential applications of bacteriotherapy. Choice A is the correct answer because it accurately reflects the central theme discussed in the passage. Choices B, C, and D are incorrect because they focus on specific details or applications mentioned in the passage, rather than capturing the overarching theme of the critical role of microorganisms in immune system function.

5. What is implied by this paragraph about food and drink?

• A. We should eat and drink in reasonable quantities.
• B. Alcohol should be banned.
• C. People should eat in large quantities.
• D. We need stronger laws to control drunk drivers.

Correct answer: A

Rationale: The paragraph emphasizes that while food and drink are necessary and desirable, their abuse can lead to serious physical and mental problems. It highlights the negative consequences of overeating and alcohol abuse, such as strain on the heart, diabetes, and other health issues. The text suggests the importance of moderation in consumption to prevent health problems. Choices B, C, and D are incorrect because the paragraph does not call for a ban on alcohol, promote eating in large quantities, or specifically discuss the need for stronger laws to control drunk drivers.
