Holy Roman Emperor

The Holy Roman Emperor was widely perceived to rule by divine right, though he often contradicted or rivaled the Pope, most notably during the Investiture controversy. 
In theory, the Holy Roman Emperor was primus inter pares (first among equals) among other Catholic monarchs. In practice, a Holy Roman Emperor was only as strong as his army and alliances, including marriage alliances, made him. There was never a Holy Roman Empress regnant, though women such as Theophanu and Maria Theresa of Austria served as de facto Empresses regnant.
Throughout its history, the position was viewed as a defender of the Roman Catholic faith.  Until the Reformation, the Emperor elect (imperator electus) was required to be crowned by the Pope before assuming the imperial title. Charles V,  Holy Roman Emperor was the last to be crowned by the Pope in 1530. Even after the Reformation, the elected Emperor always was a Roman Catholic.  There were short periods in history when the electoral college was dominated by Protestants, and the electors usually voted in their own political interest.

Rugby football

Rugby refers to the team sports rugby league and rugby union. Legend claims that Rugby football was started around the time of 1845 in Rugby School, Rugby, Warwickshire, England, although forms of football in which the ball was carried and tossed date to medieval times. Rugby eventually split into two sports in 1895 when twenty one clubs split from the original Rugby Football Union, to form the Northern Union (later to be named rugby league in 1922) in the George Hotel, Huddersfield, Northern England over the issue of payment to players, thus making rugby league the first code to turn professional and pay its players, rugby union turned fully professional in 1995. Both sports are run by their respective world governing bodies World Rugby (rugby union) and the Rugby League International Federation (rugby league). Rugby football was one of many versions of football played at English public schools in the 19th century.[1][2] Although rugby league initially used rugby union rules, they are now wholly separate sports. In addition to these two codes, both American and Canadian football evolved from rugby football.

Castle Bravo

Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on March 1, 1954, the device was the most powerful nuclear device detonated by the United States and its first lithium deuteride fueled thermonuclear weapon.[1][2] Castle Bravo's yield was 15 megatons of TNT, 2.5 times the predicted 6.0 megatons, due to unforeseen additional reactions involving 7Li,[3] which led to the unexpected radioactive contamination of areas to the east of Bikini Atoll.

Question: When was the Castle Bravo test performed?
State park

As of 2014, there were 10,234 state park units in the United States, according to the National Association of State Park Directors (NASPD).[2] There are some 739 million annual visits to the country's state parks.[2]  The NASPD further counts over 43,000 miles (69,000km) of trail, 217,367 campsites, and 8,277 cabins and lodges across U.S. state parks.[2] The largest state park system in the United States is Alaska State Parks, with over 100 sites encompassing 3.3 million acres.[3]

Religion in Austria

Christianity is the predominant religion in Austria. At the 2001 census, 73.6% of the country's population was Catholic.[5] As of 2018, the number of Catholics has dropped to 56.9% of the population, according to data provided by the Austrian Catholic Church itself.[3] There is a much smaller group of Evangelicals, totalling about 4.7% of the population in 2001, shrunk to 3.3% in 2018.[6] Since 2001, these two historically dominant religious groups in Austria recorded losses in the number of adherents. The Catholic Church reported an absolute drop of 15.7%, the Evangelical Lutheran and Evangelical Reformed churches of 1.3%. In relative numbers the losses of the smaller Evangelical churches account for 33.7%, compared to Catholic losses which account for 21.9%, since their maximum in 1971.

France–Vietnam relations

French–Vietnamese relations started as early as the 17th century with the mission of the Jesuit father Alexandre de Rhodes. Various traders would visit Vietnam during the 18th century, until the major involvement of French forces under Pigneau de Béhaine from 1787 to 1789 helped establish the Nguyễn Dynasty. France was heavily involved in Vietnam in the 19th century under the pretext of protecting the work of Catholic missionaries in the country. France progressively carved for itself a huge colony, which would form French Indochina in 1887. France continued to rule Vietnam as a colony until France's defeat in the First Indochina War and the proclamation of Vietnam's independence in 1954.

Question: What year was Vietnam colonized by the French?

Scotia

The name of Scotland is derived from the Latin Scoti, the term applied to Gaels.[2] The word Scoti (or Scotti) was first used by the Romans. It is found in Latin texts from the 4th century describing an Irish group which raided Roman Britain.[3] It came to be applied to all the Gaels. It is not believed that any Gaelic groups called themselves Scoti in ancient times, except when writing in Latin.[3] Old Irish documents use the term Scot (plural Scuit) going back as far as the 9th century, for example in the glossary of Cormac mac Cuilennáin.[4]

A Tale of a Tub




A Tale of a Tub was the first major work written by Jonathan Swift, arguably his most difficult satire and perhaps his most masterly. The Tale is a prose parody divided into sections each delving into the morals and ethics of the English. Composed between 1694 and 1697, it was eventually published in 1704. It was long regarded as a satire on religion, and has famously been attacked for that, starting with William Wotton.[1][2]

Question: When was Swift's A Tale of a Tub first published?

ABO blood group system

The ABO blood types were first discovered by an Austrian Physician Karl Landsteiner working at the Pathological-Anatomical Institute of the University of Vienna (now Medical University of Vienna). In 1900, he found that blood sera from different persons would clump together (agglutinate) when mixed in test tubes, and not only that some human blood also agglutinated with animal blood.[5] He wrote a two-sentence footnote:

Shipyard

A shipyard (also called a dockyard) is a place where ships are built and repaired.  These can be yachts, military vessels, cruise liners or other cargo or passenger ships.  Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction.  The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.

Question: What does a shipyard do?

UNESCO

After the signing of the Atlantic Charter and the Declaration of the United Nations, the Conference of Allied Ministers of Education (CAME) began meetings in London which continued from 16 November 1942 to 5 December 1945. On 30 October 1943, the necessity for an international organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States and the USSR. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944. Upon the proposal of CAME and in accordance with the recommendations of the United Nations Conference on International Organization (UNCIO), held in San Francisco in April–June 1945, a United Nations Conference for the establishment of an educational and cultural organization (ECO/CONF) was convened in London 1–16 November 1945 with 44 governments represented. The idea of UNESCO was largely developed by Rab Butler, the Minister of Education for the United Kingdom, who had a great deal of influence in its development.[10] At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, and a Preparatory Commission was established.[11] The Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCO's Constitution came into force with the deposit of the twentieth ratification by a member state.[12]

Causes of the Great Depression

The causes of the Great Depression in the early 20th century have been extensively discussed by economists and remain a matter of active debate. They are part of the larger debate about economic crises. The specific economic events that took place during the Great Depression are well established. There was an initial stock market crash that triggered a "panic sell-off" of assets. This was followed by a deflation in asset and commodity prices, dramatic drops in demand and credit, and disruption of trade, ultimately resulting in widespread unemployment (over 13 million people were unemployed by 1932) and impoverishment. However, economists and historians have not reached a consensus on the causal relationships between various events and government economic policies in causing or ameliorating the Depression.

Question: What was the main cause of the Great Depression?
Religion in Egypt

According to research by Pew Research Center for the PEW-TEMPLTON Global Religion Futures Project in 2010 94.9% of Egyptians are Sunni Muslim, 5.1% are Christian, and less than 1% are Jewish, Buddhist, or other religions.[4] The share of Christians in the Egyptian population has been declining with the highest share reported in the past century being in 1927, when the official census put the percentage of Egyptian Christians at 8.3%. In each of the seven subsequent censuses, the percentage shrank, ending at 5.7% in 1996. However, most Christians refuted these figures claiming they have been undercounted.  Christians uphold that they represent up to 15 or even 20% of the Egyptian population.[5][6][7][8][9] In 2017 state-owned newspaper Al Ahram claimed that the percentage of Christians ranged from 10 to 15%[10][11][12], similar to the range claimed by the Washington Institute for Near East Policy.[13]

2000 Pacific hurricane season

The season officially started on May 15, 2000 in the eastern Pacific, and on June 1, 2000 in the central Pacific, and lasted until November 30, 2000. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. This season had an above average number of storms. However, it had a below-average number of hurricanes and major hurricanes. There were also two tropical depressions that did not reach storm strength. In the central Pacific, two tropical storms formed. The first storm formed on May 22 and the last storm dissipated on November 8.

Question: What was the last Pacific hurricane in 2000?

Porsche

Ferdinand Porsche founded the company called "Dr. Ing. h. c. F. Porsche GmbH" in 1931,[3] with main offices at Kronenstraße 24 in the centre of Stuttgart.[4] Initially, the company offered motor vehicle development work and consulting,[3] but did not build any cars under its own name. One of the first assignments the new company received was from the German government to design a car for the people, that is a "Volkswagen".[3]  This resulted in the Volkswagen Beetle, one of the most successful car designs of all time.[5] The Porsche 64 was developed in 1939 using many components from the Beetle.[3]

Question: When was Porsche founded?
English football league system

The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with six teams from Wales and one from Guernsey also competing.  The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system, although in practice it would take a team at the bottom levels at least two decades of consistently finishing at or near the top of each successive league to reach the top level, and even then additional restrictions, particularly in regard to stadium facilities, would then come into effect at the highest levels that could prevent a club from being allowed access to the top levels.  There are more than 140 individual leagues, containing more than 480 divisions.[1]

Question: How many professional football leagues are there in the U.K.?

Submarine

In 1578, the English mathematician William Bourne recorded in his book Inventions or Devises one of the first plans for an underwater navigation vehicle. A few years later the Scottish mathematician and theologian John Napier wrote in his Secret Inventions (1596) the following: "These inventions besides devises of sayling under water with divers, other devises and strategems for harming of the enemyes by the Grace of God and worke of expert Craftsmen I hope to perform." It's unclear whether he ever carried out his idea.[5]

Question: Who invented the submarine?

Royal Canadian Air Force

The Canadian Air Force (CAF) was established in 1920 as the successor to a short-lived two-squadron Canadian Air Force that was formed during the First World War in Europe. John Scott Williams, MC, AFC, was tasked in 1921 with organizing the CAF, handing command over later the same year to Air Marshal Lindsay Gordon.[7] The new Canadian Air Force was a branch of the Air Board and was chiefly a training militia that provided refresher training to veteran pilots.[8][9] Many CAF members also worked with the Air Board's Civil Operations Branch on operations that included forestry, surveying and anti-smuggling patrols.[10]  In 1923, the CAF became responsible for all flying operations in Canada, including civil aviation.  In 1924, the Canadian Air Force, was granted the royal title, becoming the Royal Canadian Air Force (RCAF). Most of its work was civil in nature; however, in the late 1920s the RCAF evolved into more of a military organization. After budget cuts in the early 1930s, the air force began to rebuild.
