This is incredibly random, so be prepared:
An average person has never heard of the concept of anything rolling: no balls, no
gears, no wheels, nothing.
One day, he is standing atop a hill with a large, fairly round boulder next to him.
With one shove, he could start it rolling.
A deep trench encircles the hill. With spikes on the bottom. He cannot jump over the
trench, and if he stays on the hill he is in danger of starvation.
However, if he sends the boulder rolling down the hill, it will land and fit neatly
in the trench, crushing the spikes beneath and providing a bridge that the average-
primitive person could walk over.
Do you think it would occur to him to set the boulder rolling and thus save his life?
