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.

- B. We should implement stricter laws to prevent alcohol abuse.
- C. Emotional eating is a major health concern.
- D. Consuming food and drinks in moderation is crucial.
Correct answer: A
Rationale: The paragraph implies that overeating and alcohol abuse can lead to serious physical and mental health problems. It highlights the strain on the heart, risk of diabetes, and shortened lifespan due to overeating. It also mentions the negative consequences of alcohol abuse, such as alcoholism, drunk driving leading to accidents, and spousal/child abuse. While emotional eating is mentioned, the main focus is on the health risks of overeating and alcohol abuse. Therefore, choice A is the correct answer as it captures the essence of the paragraph's message.

- D. Space travel eliminated the need for utensils.
Correct answer: B
Rationale: The correct answer is B. The passage clearly states that China developed chopsticks as an efficient tool for eating, making choice B the correct statement. Choice A is incorrect as chopsticks were not developed in Europe but in China. Choice C is not supported by the passage as it does not discuss the difficulty of eating with forks. Choice D is also incorrect as space travel introduced new challenges but did not eliminate the need for utensils.

- A. Something that is able to resist and be flexible
- B. Something that is like plastic
- C. Something that is dynamic and electrifying

Correct answer: A
Rationale: 'Elasticity' refers to the ability of the arterial walls to resist and be flexible, which affects blood pressure. In the provided extract, it is mentioned that an increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. This demonstrates that elasticity refers to the property of being able to resist and be flexible, supporting choice A as the correct answer. The other choices, B, C, and D, do not accurately reflect the concept of elasticity in the context of arterial walls and blood pressure.
