Ariel liked to make guacamole, but she could often find only unripe avocados at
the grocery store. In biology class, Ariel
learned that ripe fruits produce a gas
called ethylene that can cause other fruits
to ripen. Ariel wondered whether storing
ripe bananas with unripe avocados would
make the avocados ripen faster.
Ariel prepared four paper bags with five
unripe avocados in each bag. She added
one ripe banana to two of the bags and no
bananas to the reinaining two bags. Then,
Ariel sealed all four bags. After three days,
she opened each bag and counted the
number of ripe avocados in each bag.
