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.

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.

Correct Answer: A

Rationale: The passage implies that playing bridge requires concentration, focus, and mental effort. It mentions that Bridge can be complicated for beginners but with time, effort, and a good teacher, even novices can become proficient.

Rationale: The author's primary purpose for writing the passage on the Amazon Rainforest is to inform readers about the deforestation and environmental challenges facing the Amazon. The passage provides detailed information about the Amazon Rainforest, its biodiversity, the impact of deforestation on the environment, and the dangers associated with the destruction of the rainforest. Choice A is incorrect because the author's goal is not to entertain but to educate readers. Choice C is incorrect as there is no persuasive language used to encourage readers to visit the Amazon Rainforest. Choice D is also incorrect as the passage does not focus on criticizing farming practices but rather on highlighting the environmental threats and consequences of deforestation.

Correct Answer: B

Rationale: The author suggests that the Earth's tilt affects the amount of sunlight different areas receive, influencing the seasons. The passage explains how the tilt of the Earth towards the sun results in different regions receiving varying amounts of sunlight, leading to the existence of seasons. This tilt causes regions near the equator to receive more sunlight consistently, while the Poles experience periods of constant darkness or sunlight, creating different seasons. Choices A, C, and D are incorrect because the passage clearly states that the Earth's tilt influences sunlight distribution and subsequently impacts the seasons.
