Problem: British Isles:

At the time of the Roman Empire, about two thousand years ago, various tribes, which spoke Celtic dialects of the Insular Celtic group, were inhabiting the islands. The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark the northern frontier of their empire in 122 AD. At that time, Ireland was populated by a people known as Hiberni, the northern third or so of Great Britain by a people known as Picts and the southern two thirds by Britons.

What was the name of the native people that lived in the southern parts of the British Isles during the Roman Empire occupation?
---
A: Britons

Problem: Between 1836 and 1842 Victorian Aboriginal groups were largely dispossessed[by whom?] of their land. By January 1844, there were said to be 675 Aborigines resident in squalid camps in Melbourne. The British Colonial Office appointed five Aboriginal Protectors for the Aborigines of Victoria, in 1839, however their work was nullified by a land policy that favoured squatters to take possession of Aboriginal lands. By 1845, fewer than 240 wealthy Europeans held all the pastoral licences then issued in Victoria and became a powerful political and economic force in Victoria for generations to come.
Who appointed five Aboriginal Protectors for the Aborigines of Victoria in 1839?

Answer: The British Colonial Office

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the Roman Catholic Church, obstinate and willful manifest heresy is considered to spiritually cut one off from the Church, even before excommunication is incurred. The Codex Justinianus (1:5:12) defines "everyone who is not devoted to the Catholic Church and to our Orthodox holy Faith" a heretic. The Church had always dealt harshly with strands of Christianity that it considered heretical, but before the 11th century these tended to centre around individual preachers or small localised sects, like Arianism, Pelagianism, Donatism, Marcionism and Montanism. The diffusion of the almost Manichaean sect of Paulicians westwards gave birth to the famous 11th and 12th century heresies of Western Europe. The first one was that of Bogomils in modern day Bosnia, a sort of sanctuary between Eastern and Western Christianity. By the 11th century, more organised groups such as the Patarini, the Dulcinians, the Waldensians and the Cathars were beginning to appear in the towns and cities of northern Italy, southern France and Flanders.
What group moved westward to give rise to the famous 11th and 12th century heresy in western Europe?
A: Paulicians
