7. You have landed the plane safely on the lake and are ready to turn in for the night. So that it doesn't freeze overnight (the temparature has been known to drop to below -60C), you must remove the oil from the engine. How will you manage this?

By draining the oil onto the ground and letting it freeze so it can be taken inside to thaw overnight for use tomorrow.

No need to drain the oil; it won't freeze overnight.

By setting up a tarp over the engine, aiming a heater on the engine, and draining the oil into a container.
