[Q]: Pope John XXIII did not live to see the Vatican Council to completion. He died of stomach cancer on 3 June 1963, four and a half years after his election and two months after the completion of his final and famed encyclical, Pacem in terris. He was buried in the Vatican grottoes beneath Saint Peter's Basilica on 6 June 1963 and his cause for canonization was opened on 18 November 1965 by his successor, Pope Paul VI, who declared him a Servant of God. In addition to being named Venerable on 20 December 1999, he was beatified on 3 September 2000 by Pope John Paul II alongside Pope Pius IX and three others. Following his beatification, his body was moved on 3 June 2001 from its original place to the altar of Saint Jerome where it could be seen by the faithful. On 5 July 2013, Pope Francis – bypassing the traditionally required second miracle – declared John XXIII a saint, after unanimous agreement by a consistory, or meeting, of the College of Cardinals, based on the fact that he was considered to have lived a virtuous, model lifestyle, and because of the good for the Church which had come from his having opened the Second Vatican Council. He was canonised alongside Pope Saint John Paul II on 27 April 2014. John XXIII today is affectionately known as the "Good Pope" and in Italian, "il Papa buono".

[Q]: Many ancient civilizations alloyed metals for purely aesthetic purposes. In ancient Egypt and Mycenae, gold was often alloyed with copper to produce red-gold, or iron to produce a bright burgundy-gold. Gold was often found alloyed with silver or other metals to produce various types of colored gold. These metals were also used to strengthen each other, for more practical purposes. Copper was often added to silver to make sterling silver, increasing its strength for use in dishes, silverware, and other practical items. Quite often, precious metals were alloyed with less valuable substances as a means to deceive buyers. Around 250 BC, Archimedes was commissioned by the king to find a way to check the purity of the gold in a crown, leading to the famous bath-house shouting of "Eureka!" upon the discovery of Archimedes' principle.
[A]: Ancient civilizations often alloyed metals for what reason?


[Q]: The best-known medieval Chinese name for Tibet is Tubo (Chinese: 吐蕃 also written as 土蕃 or 土番; pinyin: Tǔbō or Tǔfān). This name first appears in Chinese characters as 土番 in the 7th century (Li Tai) and as 吐蕃 in the 10th-century (Old Book of Tang describing 608–609 emissaries from Tibetan King Namri Songtsen to Emperor Yang of Sui). In the Middle Chinese spoken during that period, as reconstructed by William H. Baxter, 土番 was pronounced thux-phjon and 吐蕃 was pronounced thux-pjon (with the x representing tone).
