Worn or stuck piston rings allow hot combustion gases to pass down into the scavenge space, igniting the oily residue.
Surging occurs when the pressure downstream of the compressor is higher than the pressure generated by the compressor itself, causing a reversal of airflow. Causes include sudden engine load variations, dirty scavenge ports, fouled exhaust valves, or a fouled turbocharger nozzle ring. Management must reduce engine load smoothly, inspect the air/exhaust paths, and clean the turbocharger components via water washing or dry grit washing as per manufacturer specifications.
That answer is 100% exclusive to slow-speed, 100% correct for STCW, and will differentiate you from the medium-speed candidates.

A scavenge fire requires three elements: fuel (unburnt cylinder oil or leaked fuel oil), air (highly pressurized scavenge air), and heat (blow-by of hot combustion gases past worn piston rings). Step-by-Step Emergency Response Protocol
The oil mist ignites at the hot spot. This creates a relatively mild pressure wave that opens the crankcase relief valves.

Localized overheating of a bearing (a "hot spot") vaporizes lubricating oil. When this oil vapor mixes with air, it creates a highly explosive oil mist.
