1. Choose the best summary of the passage about microbes.

A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.

Correct answer: C

Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.

2. 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.

3. How does the author want the reader to feel after reading about Bridge?

A. As though the game of Bridge is too hard for novices to learn
B. Frustrated and confused about playing bridge
C. Confident and excited about learning Bridge
D. Overwhelmed by all the rules for the game of Bridge

Correct answer: C

Rationale: The author wants the reader to feel confident and excited about learning the game of Bridge.

The tone of the writing is encouraging and informative, providing tips and explanations to help the reader understand the game better and increase their interest in playing Bridge. Choices A, B, and D are incorrect because the text does not convey that the game is too hard for novices, aims to frustrate or confuse the reader, or overwhelm them with rules. Instead, the author's intention is to inspire confidence and excitement in learning this exciting card game.

4. What can the reader conclude from this passage about ponds and lakes?

A. They are examples of groundwater reservoirs.
B. They are part of the evaporation process.
C. They are formed by runoff.
D. They are formed by condensation.

Correct answer: A

Rationale: The correct answer is A: 'They are examples of groundwater reservoirs.' The passage mentions that runoff collects in groundwater reservoirs, among other places. Ponds and lakes are typically reservoirs of groundwater, as stated in the passage. Choice B is incorrect because ponds and lakes are not directly mentioned as part of the evaporation process. Choice C is incorrect as ponds and lakes are not stated to be formed by runoff. Choice D is incorrect as ponds and lakes are not formed by condensation.

5. Why was the roadway so dangerous to build?

A. There weren't enough materials available to build the road
B. The workers might get hit by passing cars
C. The men would fall to their deaths
D. The men would be attacked by animals.

Correct answer: C

Rationale: The roadway was dangerous to build because the men involved in the construction were at risk of falling to their deaths. The excerpt mentions that the construction of the roadway was the most dangerous and treacherous part of the entire task, indicating a high risk of falling due to the height and precarious nature of the construction site. Choice A is incorrect because the danger was due to the physical risks of falling and not due to a lack of materials. Choice B is incorrect as passing cars were not the primary danger during the construction of the roadway. Choice D is incorrect since there is no mention of workers being attacked by animals during the construction of the Golden Gate Bridge.
