14. Jack and Jill wanted to prove their theory so they
invited 60 individuals to participate in their
experiment. They sent the participants up their
most hated hill, on foot, to fetch water and
recorded how many times they fell down and
broke their crown and stumbled after. Jack and
Jill were happy to learn that it was not just them.
So they sent them to fetch water again but this
time, they wore special boots. They recorded again
the number of times they fell down and broke their
crown and stumbled after.
