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.

4. What is the meaning of the word delicate as used in the first paragraph?

A. Subtle
B. Fragile
C. Refined
D. Intricate

Correct answer: D

Rationale: In the context of microsurgery, the word 'delicate' refers to the intricate, precise, and fine nature of surgeries performed using microscopy. These surgeries require intricate attention to detail and precision due to the small and delicate structures involved, making 'intricate' the most appropriate synonym. 'Subtle' implies understated or not obvious, 'fragile' suggests easily broken or damaged, and 'refined' refers to something developed or improved over time, none of which fully capture the detailed and precise nature of microsurgery. Therefore, 'intricate' is the correct answer.

C. The different colors can be used in simple medical tests to indicate infection or disease.
D. Unique properties of materials emerge.

Correct answer: D

Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.
