• C. To entertain
• D. To analyze

Correct answer: B

Rationale: The author's primary purpose is to inform readers about the crucial role of microorganisms in the immune system. The essay focuses on presenting factual information and recent discoveries regarding the impact of microbes on human health. The author aims to educate the readers on the significance of microbes in human health rather than persuade them of a particular viewpoint (Choice A), entertain them with light-hearted content (Choice C), or analyze in-depth data and findings (Choice D).

Correct answer: A

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.

• A. The author explains differences in eating methods.
• B. Eating habits vary across different cultures.
• C. Space travel has posed challenges for eating habits.
• D. Chopsticks are more suitable than forks for space travel.

Correct answer: A

Rationale: The correct answer is A. The passage discusses different eating methods in various cultures, focusing on their differences. The author describes the development of cutlery in European cultures, the use of chopsticks in China, and how space travel has influenced eating tools for astronauts. Choice B is incorrect because the passage emphasizes the differences rather than the similarities in eating habits across cultures. Choice C is partially supported by the passage as it mentions that space travel has created new challenges for consuming food, but it is not the main conclusion of the article. Choice D is not directly supported by the passage as it discusses the challenges of using chopsticks and forks in space rather than stating that chopsticks are superior to forks.

• A. Global warming is caused by deforestation.
• B. Global warming is unrelated to deforestation.
• C. Global warming is exaggerated.
• D. Global warming is not a concern.

Correct answer: A

Rationale: The correct statement about global warming in the passage on the Amazon Rainforest is that it is caused by deforestation. The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year. Choice B is incorrect as the passage clearly establishes a direct link between deforestation and global warming. Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation. Choice D is incorrect as the passage emphasizes the serious concern of global warming due to deforestation.
