PROBLEM: The Australian government controls the exclusive economic zone (EEZ) and revenue from it extending 200 nautical miles (370 km) around Norfolk Island (roughly 428,000km2) and territorial sea claims to three nautical miles (6 km) from the island. There is a strong belief on the island that some of the revenue generated from Norfolk's EEZ should be available to providing services such as health and infrastructure on the island, which the island has been responsible for, similar to how the Northern Territory is able to access revenue from their mineral resources. The exclusive economic zone provides the islanders with fish, its only major natural resource. Norfolk Island has no direct control over any marine areas but has an agreement with the Commonwealth through the Australian Fisheries Management Authority (AFMA) to fish "recreationally" in a small section of the EEZ known locally as "the Box". While there is speculation that the zone may include oil and gas deposits, this is not proven. There are no major arable lands or permanent farmlands, though about 25 per cent of the island is a permanent pasture. There is no irrigated land. The island uses the Australian dollar as its currency.

SOLUTION: What services do Norfolk Island residents believe should be made available from the Norfolk Island's EEZ profit?

PROBLEM: Building construction is the process of adding structure to real property or construction of buildings. The majority of building construction jobs are small renovations, such as addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, and design team for the entire project. Although building construction projects typically include various common elements, such as design, financial, estimating and legal considerations, many projects of varying sizes reach undesirable end results, such as structural collapse, cost overruns, and/or litigation. For this reason, those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome.

SOLUTION: What is the process of adding structure to real property or construction of buildings?

PROBLEM: Gram quantities of various copper salts have been taken in suicide attempts and produced acute copper toxicity in humans, possibly due to redox cycling and the generation of reactive oxygen species that damage DNA. Corresponding amounts of copper salts (30 mg/kg) are toxic in animals. A minimum dietary value for healthy growth in rabbits has been reported to be at least 3 ppm in the diet. However, higher concentrations of copper (100 ppm, 200 ppm, or 500 ppm) in the diet of rabbits may favorably influence feed conversion efficiency, growth rates, and carcass dressing percentages.

SOLUTION:
What are copper salts sometimes used for?
