During preflight, the engine oil level should be between which two marks on the sight glass when checked within 15 minutes of shutdown?

Explanation:
Oil level readings on the engine sight glass must fall within the labeled MIN and MAX marks after a brief cool-down, because oil drains back into the sump when the engine is shut down. Checking within 15 minutes lets the level settle so the reading is accurate, and being between MIN and MAX confirms there is enough oil for lubrication without overfill. Ranges that include the bottom, top, or exceed the MIN/MAX window don’t reflect the acceptable level, so they’re not correct.
