I need in depth answers for each point (a-e) not only a short note per each point. Thank you so much in advanced!! :)

You manage and own an outdoor sports park, which includes baseball fields, basketball courts and a deck hockey rink.The sports park's regular business hours are from dawn until dusk.With sports in play, there are risks of foul balls, etc.Also, looking to expand and improve the facility, you begin construction on a new dugout, and the contractor's backhoe remains parked on the premises during the construction and a large ditch is exposed for several days prior to construction of the dugout walls.Discuss the duty that you, as owner, would owe to (a) families who visit the sports park during business hours to participate in sporting events, (b) workmen constructing the new dugout, (c) a newspaper reporter who wants to cover a game for his sports column (d) children who decide to play on the backhoe after hours having seen the backhoe during a recent visit to the sports park, and (e) a homeless man who unbeknownst to you, attempts to sleep in the sports park overnight.What steps you should take as manager/owner to demonstrate the appropriate standard of care to each of these parties?
