Correct Answer: C

Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.

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: B

Rationale: "Afforded to" in this context means "presented to," as it refers to the education options available to women at the time.

Correct Answer: B

Rationale: The passage mentions reduced blood pressure, improved memory, and alleviated depression as potential benefits of omega-3s but does not mention a reduced risk of diabetes.

Correct Answer: A

Rationale: The author primarily aims to persuade the reader of the health benefits of omega-3 fatty acids and encourages ensuring sufficient omega-3 intake through diet.
