A car
Explanation ;
A car runs on multiple complicated objects, that arenât simply fixed or made by anybody,
a nail wether itâs a nail from the hand or nail to hammer, theyâre neither ran as a machine, that wouldnât be possible-
A pen isnât a machine but I would understand if you got stuck on that one,
A spoon, in no way shape or form is a complicated machine, or even a regular machine in general.
So your answer is car.
