In one class I took, we were examining a range of car engines for faults and the task was to get it running.

The rumour was that the previous years class had one engine where the ignition rotor arm wire had been replaced by section of coloured plastic which was covered in the usual grease and crap in the housing.

The instructor was looking for persistence and elimination of possibilities rather than actually solving it. But one team did. As long as you solved the others that was enough to complete the class.
