Article: The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.

Question: What fraction of land was under cultivation using the two-field system?
Ans: one half

Article: Although the Catholics and the Orthodox may honor and venerate Mary, they do not view her as divine, nor do they worship her. Roman Catholics view Mary as subordinate to Christ, but uniquely so, in that she is seen as above all other creatures. Similarly Theologian Sergei Bulgakov wrote that the Orthodox view Mary as "superior to all created beings" and "ceaselessly pray for her intercession". However, she is not considered a "substitute for the One Mediator" who is Christ. "Let Mary be in honor, but let worship be given to the Lord", he wrote. Similarly, Catholics do not worship Mary as a divine being, but rather "hyper-venerate" her. In Roman Catholic theology, the term hyperdulia is reserved for Marian veneration, latria for the worship of God, and dulia for the veneration of other saints and angels. The definition of the three level hierarchy of latria, hyperdulia and dulia goes back to the Second Council of Nicaea in 787.

Question: Which theologian wrote that Mary is considered to be "superior to all created beings," but is not to be the object of worhip?
Ans: Sergei Bulgakov

Article: In September 1939, Britain entered the Second World War, which lasted until 1945. During the war, many of London's children were evacuated to avoid the frequent aerial bombing. The suggestion by senior politician Lord Hailsham that the two princesses should be evacuated to Canada was rejected by Elizabeth's mother, who declared, "The children won't go without me. I won't leave without the King. And the King will never leave." Princesses Elizabeth and Margaret stayed at Balmoral Castle, Scotland, until Christmas 1939, when they moved to Sandringham House, Norfolk. From February to May 1940, they lived at Royal Lodge, Windsor, until moving to Windsor Castle, where they lived for most of the next five years. At Windsor, the princesses staged pantomimes at Christmas in aid of the Queen's Wool Fund, which bought yarn to knit into military garments. In 1940, the 14-year-old Elizabeth made her first radio broadcast during the BBC's Children's Hour, addressing other children who had been evacuated from the cities. She stated: "We are trying to do all we can to help our gallant sailors, soldiers and airmen, and we are trying, too, to bear our share of the danger and sadness of war. We know, every one of us, that in the end all will be well."

Question: Who rejected the idea of sending the princesses away?
Ans: Elizabeth's mother

Article: Prior Diego saw immediately one of the paramount reasons for the spread of the unorthodox movement: the representatives of the Holy Church acted and moved with an offensive amount of pomp and ceremony. On the other hand, the Cathars lived in a state of self-sacrifice that was widely appealing. For these reasons, Prior Diego suggested that the papal legates begin to live a reformed apostolic life. The legates agreed to change if they could find a strong leader. The prior took up the challenge, and he and Dominic dedicated themselves to the conversion of the Albigensians. Despite this particular mission, in winning the Albigensians over by persuasion Dominic met limited success, "for though in his ten years of preaching a large number of converts were made, it has to be said that the results were not such as had been hoped for."

Question: Who did Diego and Dominic try to convert?
Ans:
the Albigensians
