Imagine that your father has a big farm that he has been running successfully for a very long time. His health is down at the moment. Thus he has asked you to go and clean the farm today. You know a thing or two about farm maintenance and so you readily accepted the responsibility and went to the farm to do the cleaning task. The cleaning of the farm was completed but then the farm exit key fell into the small pond in the farm. You will now need to find the diving equipment that you will have to use to dive into the pond to look for the key that you must have to get back home.
