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. Which might be a good title for this passage?

A. “Everyone Should Run Barefoot”
B. “How to Prevent Running Injuries”

Rationale: The title "The Debate over Barefoot Running" encapsulates the central theme of the passage, which explores both the advantages and disadvantages of barefoot running.
