Problem: Norfolk Island Hospital is the only medical centre on the island. Medicare and the Pharmaceutical Benefits Scheme do not cover Norfolk Island. All visitors to Norfolk Island, including Australians, are recommended to purchase travel insurance. Although the hospital can perform minor surgery, serious medical conditions are not permitted to be treated on the island and patients are flown back to mainland Australia. Air charter transport can cost in the order of A$30,000. For serious emergencies, medical evacuations are provided by the Royal Australian Air Force. The island has one ambulance staffed by St John Ambulance Australia volunteers.
Where are Norfolk Island patients who need serious treatment imprisoned?

Problem: Among other inhabitants of London are 10,000 foxes, so that there are now 16 foxes for every square mile (2.6 square kilometres) of London. These urban foxes are noticeably bolder than their country cousins, sharing the pavement with pedestrians and raising cubs in people's backyards. Foxes have even sneaked into the Houses of Parliament, where one was found asleep on a filing cabinet. Another broke into the grounds of Buckingham Palace, reportedly killing some of Queen Elizabeth II's prized pink flamingos. Generally, however, foxes and city folk appear to get along. A survey in 2001 by the London-based Mammal Society found that 80 percent of 3,779 respondents who volunteered to keep a diary of garden mammal visits liked having them around. This sample cannot be taken to represent Londoners as a whole.

Problem: The Eastern Roman Empire today conventionally named the Byzantine Empire, a name not in use during its own time became increasingly influenced by Greek culture after the 7th century, when Emperor Heraclius (AD 575 - 641) decided to make Greek the empire's official language. Certainly from then on, but likely earlier, the Roman and Greek cultures were virtually fused into a single Greco-Roman world. Although the Latin West recognized the Eastern Empire's claim to the Roman legacy for several centuries, after Pope Leo III crowned Charlemagne, king of the Franks, as the "Roman Emperor" on 25 December 800, an act which eventually led to the formation of the Holy Roman Empire, the Latin West started to favour the Franks and began to refer to the Eastern Roman Empire largely as the Empire of the Greeks (Imperium Graecorum).
