Inner ear problem, hearing.

Correct Answer: B

Rationale: The correct answer is B: Nerves. In the context of an inner ear problem related to hearing, the issue is most likely related to the auditory nerve, which transmits signals from the cochlea to the brain for interpretation. Problems with this nerve can lead to hearing difficulties. Choice A (Conduction) typically refers to issues with sound conduction through the ear canal or middle ear, not the inner ear. Choices C and D are likely irrelevant since they are not specified and do not directly pertain to the inner ear or hearing. Therefore, choice B is the most appropriate because it directly addresses the nerve involvement in hearing function.

Correct Answer: B

Rationale: The correct answer is B: Inside a jar. Stool specimens should be collected inside a clean, dry, leak-proof container such as a jar to prevent contamination and ensure accurate testing. Choice A (1 inch) is too vague and does not specify the proper collection method. Choices C and D are incomplete and do not provide any relevant information on how to collect and store a stool specimen. It is essential to follow proper collection procedures to avoid inaccurate test results.
