For Question 33:

When switching to high power from a clear low-power image, the issue is usually centering, focus, or lighting, not a dirty lens. Cleaning the lens is unnecessary as a first step, while verifying the low-power image, using fine focus, or asking for help are logical initial or follow-up steps.
