It also mentions the vast variety of insects, trees, and plants present in the rainforest, showcasing its rich ecosystem. Choice A is incorrect as the passage does not directly state that the Amazon Rainforest is shrinking rapidly, although it does mention the dangers it faces. Choice C is incorrect as the passage clearly indicates that human activity, such as deforestation, poses a significant threat to the rainforest. Choice D is incorrect as the passage provides evidence of a high number of animals inhabiting the Amazon Rainforest.

Rationale: The correct answer is C: 'To explain the tradition of giving white elephants.' The passage provides historical context about the practice of giving white elephants as gifts in ancient Siam, now Thailand.

The author's purpose is to shed light on this tradition and its implications, not to inform readers about Thailand in general (choice A), entertain with fun facts (choice B), or criticize the tradition (choice D). Choices A and B are incorrect because the passage focuses specifically on the tradition of giving white elephants, not on broader aspects of Thailand or entertainment. Choice D is incorrect because the passage does not criticize the tradition but rather provides a factual account of its historical significance.
