You are doing research for a state law problem about the liability of owners of the recreational land to people who use those premises. Your client has sued a landowner for the death of his sons, aged 6 and 8, who drowned in a pond on the landowners' property. There are two questions involved, whether the land is "recreational land", and if so, whether the landowner did not fulfill his legal duties.

How relevant are the following authorities to your analysis of this problem?

1. A newspaper article about accidents in parks.

1. A Statue of the state that limits the liability of owners of recreation land.

1. The regulations of a state agency requiring safety features on recreational land that is open to the public.

1. A brochure printed by the owner of the recreational land.

e. Case law from the state's intermediate appellate courts interpreting the statutory term "recreational land".

f. Case law from the highest court of another state that has an almost identical statute, interpreting the term "recreational land".

g. A case from your state's appellate court that interprets the term "recreational area" in a different statute in that same state about licensing for privately owned recreational areas.

h. The notes of the drafters of a uniform act about liability of owners of recreational areas, an act that your state has adopted.
