question:
Passage: The town was built on the mouth of a small tributary of the Severn Estuary near the mouth of the River Avon. The old pill or jetty provided protection for craft against the Bristol Channel's large tidal range, and iron rings can be seen in the high street at which fishing boats used to moor. Its position meant Portishead was used to guard the "King Road", as the waters around the headland are called. In 1497 it was the departure point for John Cabot on the Matthew. A fort was built on Battery Point, and was used during the English Civil War when the town supported the Royalists, but surrendered to Fairfax in 1645. Guns were also placed at Battery Point during World War II. The King Road was the site of a naval action in 1758 when HMS Antelope captured HMS Belliqueux, one of a French squadron returning from Quebec.

question:
Passage: In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.

question:
Passage: In 1007, Holy Roman Emperor Henry II made Bamberg a family inheritance, the seat of a separate diocese. The Emperor's purpose in this was to make the Diocese of Würzburg less unwieldy in size and to give Christianity a firmer footing in the districts of Franconia, east of Bamberg. In 1008, after long negotiations with the Bishops of Würzburg and Eichstätt, who were to cede portions of their dioceses, the boundaries of the new diocese were defined, and Pope John XVIII granted the papal confirmation in the same year. Henry II ordered the building of a new cathedral, which was consecrated 6 May 1012. The church was enriched with gifts from the pope, and Henry had it dedicated in honor of him. In 1017 Henry also founded Michaelsberg Abbey on the Michaelsberg ("Mount St. Michael"), near Bamberg, a Benedictine abbey for the training of the clergy. The emperor and his wife Kunigunde gave large temporal possessions to the new diocese, and it received many privileges out of which grew the secular power of the bishop. Pope Benedict VIII visited Bamberg in 1020 to meet Henry II for discussions concerning the Holy Roman Empire. While he was here he placed the diocese in direct dependence on the Holy See. He also personally consecrated some of Bamberg's churches. For a short time Bamberg was the centre of the Holy Roman Empire. Henry and Kunigunde were both buried in the cathedral.
