Input: Greeks
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).

What made the Eastern Empire be known as the Imperium Graecorum ?
Output: Pope Leo III crowned Charlemagne, king of the Franks, as the "Roman Emperor"

Input: Article: Internationally, Victoria took a keen interest in the improvement of relations between France and Britain. She made and hosted several visits between the British royal family and the House of Orleans, who were related by marriage through the Coburgs. In 1843 and 1845, she and Albert stayed with King Louis Philippe I at chateau d'Eu in Normandy; she was the first British or English monarch to visit a French one since the meeting of Henry VIII of England and Francis I of France on the Field of the Cloth of Gold in 1520. When Louis Philippe made a reciprocal trip in 1844, he became the first French king to visit a British sovereign. Louis Philippe was deposed in the revolutions of 1848, and fled to exile in England. At the height of a revolutionary scare in the United Kingdom in April 1848, Victoria and her family left London for the greater safety of Osborne House, a private estate on the Isle of Wight that they had purchased in 1845 and redeveloped. Demonstrations by Chartists and Irish nationalists failed to attract widespread support, and the scare died down without any major disturbances. Victoria's first visit to Ireland in 1849 was a public relations success, but it had no lasting impact or effect on the growth of Irish nationalism.

Now answer this question: What was the name of the King of Normandy that Victoria and Albert stayed with in 1843 and 1845?

Output: King Louis Philippe I

Article: Whitehead's most complete work on education is the 1929 book The Aims of Education and Other Essays, which collected numerous essays and addresses by Whitehead on the subject published between 1912 and 1927. The essay from which Aims of Education derived its name was delivered as an address in 1916 when Whitehead was president of the London Branch of the Mathematical Association.

He opined that "education with inert ideas is not only useless: it is, above all things, harmful."

China, France, Russia, the United Kingdom and the United States are often referred to as great powers by academics due to "their political and economic dominance of the global arena". These five nations are the only states to have permanent seats with veto power on the UN Security Council. They are also the only recognized "Nuclear Weapons States" under the Nuclear Non-Proliferation Treaty, and maintain military expenditures which are among the largest in the world. However, there is no unanimous agreement among authorities as to the current status of these powers or what precisely defines a great power. For example, sources have at times referred to China, France, Russia and the United Kingdom as middle powers.
How many countries are permanent seats on the UN Security Council?
