A student notices that when bananas are kept near other fruits, the other fruits ripen faster. She wonders what causes the other fruits to ripen more quickly and
thinks that bananas must have an influence on the ripening process. She decides to perform an experiment. She gathers bananas and apples and places an apple by
itself at location A and an apple next to a banana at location B. She then waits for five days and records the how ripe each apple is.
What would be the next step in this experiment?
