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.

Correct Answer: A

Rationale: In this context, "moderate" means to diminish or reduce the severity of symptoms, such as those of attention deficit hyperactive disorder.

Choice A is incorrect because the passage does not specify that humans are the only mammals that exhibit symptoms when infected by Borrelia burgdorferi. Choice B is incorrect as the passage mentions that the life cycle of an uninfected tick includes a dormant phase before the nymph stage, without excluding it. Choice D is incorrect because the passage does not state that the combination of fever, headache, and joint pain is a definitive sign of Lyme disease.
