5. The passage mentions all of these uses for microscopy EXCEPT ___________.

A. Ear surgery

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.
