Apart from temperature there are few differences between carrying cargoes of chilled meat, minus 1 degree Celsius, and frozen meat, minus 18 degrees Celsius. A key difference is that for frozen meat the cooling fans are operated at half speed or some are switched off whereas for chilled meat the fans are run constantly at full speed. Select, from the options given, the main reason for this difference in fan operation.
It is an energy saving measure since chilled meat cargoes do not require as much cold air.
The chilled meat is more sensitive to damage and therefore tighter temperature control is necessary.
The fans may be damaged if they were run at full speed delivering very cold air to the frozen cargo.
Running the fans at full speed would generate too much heat which may affect the frozen meat.

Large slow speed diesel engines are usually of the crosshead type and have various arrangements to deliver lubricating oil directly to the crosshead bearings and guides to ensure adequate lubrication. Why are the crosshead bearings considered differently to the other bearing in this type of engine in respect of lubrication requirements?
The lubricating oil has further to travel to the crosshead bearing and so a separate arrangement is necessary
The crosshead bearing is more heavily loaded than other bearings in the engine so requires more oil to keep it cool.
The crosshead bearing is closer to the engine cylinder and therefore runs hotter.
The running surfaces oscillate relative to each other during operation rather than rotate and therefore full film hydrodynamic lubrication is not possible.
