Please answer this: Extract the answer to the question from the following context. Question: When John was rising to power, what were the four men associated with him? Context: Historical interpretations of John have been subject to considerable change over the years. Medieval chroniclers provided the first contemporary, or near contemporary, histories of John's reign. One group of chroniclers wrote early in John's life, or around the time of his accession, including Richard of Devizes, William of Newburgh, Roger of Hoveden and Ralph de Diceto. These historians were generally unsympathetic to John's behaviour under Richard's rule, but slightly more positive towards the very earliest years of John's reign. Reliable accounts of the middle and later parts of John's reign are more limited, with Gervase of Canterbury and Ralph of Coggeshall writing the main accounts; neither of them were positive about John's performance as king. Much of John's later, negative reputation was established by two chroniclers writing after the king's death, Roger of Wendover and Matthew Paris, the latter claiming that John attempted conversion to Islam in exchange for military aid from the Almohad ruler Muhammad al-Nasir - a story which is considered to be untrue by modern historians.

Please answer this: Extract the answer to the question from the following context. Question: What is the Canadian term for Gesamtschule? Context: A comprehensive school is a state school that does not select its intake on the basis of academic achievement or aptitude. This is in contrast to the selective school system, where admission is restricted on the basis of selection criteria. The term is commonly used in relation to England and Wales, where comprehensive schools were introduced on an experimental basis in the 1940s and became more widespread from 1965. About 90% of British secondary school pupils now attend comprehensive schools. They correspond broadly to the public high school in the United States and Canada and to the German Gesamtschule.[citation needed]

Please answer this: Extract the answer to the question from the following context. Question: __ conceded the Peace of Augsburg. Context: Martin Luther, a German monk, started the German Reformation by posting 95 theses on the castle church of Wittenberg on October 31, 1517. The immediate provocation spurring this act was Pope Leo X's renewal of the indulgence for the building of the new St. Peter's Basilica in 1514. Luther was challenged to recant his heresy at the Diet of Worms in 1521. When he refused, he was placed under the ban of the Empire by Charles V. Receiving the protection of Frederick the Wise, he was then able to translate the Bible into German.
