Phanerozoic

The Phanerozoic Eon[3]  is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers 541 million years to the present,[4] and began with the Cambrian Period when diverse hard-shelled animals first appeared. Its name was derived from the Ancient Greek words φανερός (phanerós) and ζωή (zōḗ), meaning visible life, since it was once believed that life began in the Cambrian, the first period of this eon. The term "Phanerozoic" was coined in 1930 by the American geologist George Halcott Chadwick (1876–1953).[5][6] The time before the Phanerozoic, called the Precambrian, is now divided into the Hadean, Archaean and Proterozoic eons.

Question: When did the Phanerozoic Eon begin?
Answer: covers 541 million years to the present
Catherine the Great

Princess Sophie's father, a devout German Lutheran, opposed his daughter's conversion to Eastern Orthodoxy. Despite his objection, on 28 June 1744 the Russian Orthodox Church received Princess Sophie as a member with the new name Catherine (Yekaterina or Ekaterina) and the (artificial) patronymic Алексеевна (Alekseyevna, daughter of Aleksey). On the following day, the formal betrothal took place. The long-planned dynastic marriage finally occurred on 21 August 1745 in Saint Petersburg. Sophia had turned 16; her father did not travel to Russia for the wedding. The bridegroom, known then as Peter von Holstein-Gottorp, had become Duke of Holstein-Gottorp (located in the north-west of present-day Germany near the border with Denmark) in 1739. The newlyweds settled in the palace of Oranienbaum, which remained the residence of the "young court" for many years to come.

Common law

The common law—so named because it was "common" to all the king's courts across England—originated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066.[10] The British Empire spread the English legal system to its historical colonies, many of which retain the common law system today.  These "common law systems" are legal systems that give great precedential weight to common law, and to the style of reasoning inherited from the English legal system.[11][12][13][14]

John F. Kennedy assassination rifle

In March 1963, Lee Harvey Oswald, using the alias "A. Hidell", purchased by mail order a 6.5×52mm Carcano Model 91/38 infantry rifle (described by the President's Commission on the Assassination of President Kennedy as a "Mannlicher–Carcano") rifle with a telescopic sight.[1] He also purchased a revolver from a different company, by the same method. The Hidell alias was determined from multiple sources to be Oswald.[2] Oswald fired the rifle from the Texas School Book Depository in Dallas, Texas, to assassinate U.S. President John F. Kennedy as his motorcade drove by on November 22, 1963.[3] Photographs of Oswald holding the rifle, a palmprint found upon examination of the rifle, and detective work tracing its sale, all eventually led to Oswald.[4] Marina Oswald later testified she was told by Lee that the rifle was also used before in an attempt to assassinate retired U.S. Army General Edwin Walker in Dallas.

Question: What gun was used in the assassination of JFK?
Answer: 6.5×52mm Carcano Model 91/38 infantry rifle

History of Sudan (1956–69)

On 1 January 1956 Anglo-Egyptian Sudan became the independent Republic of the Sudan. Before 1955, however, the government under Ismail al-Azhari had temporarily halted Sudan's progress toward self-determination, hoping to promote unity with Egypt. Despite his pro-Egyptian National Unionist Party (NUP) winning a majority in the 1953 parliamentary elections, however, Azhari realized that popular opinion had shifted against such a union. Azhari, who had been the major spokesman for the "unity of the Nile Valley", therefore reversed the NUP's stand and supported Sudanese independence. On December 19, 1955, the Sudanese parliament, under Azhari's leadership, unanimously adopted a declaration of independence that became effective on January 1, 1956. Azhari called for the withdrawal of foreign troops and requested the condominium powers to sponsor a plebiscite in advance.

Question: When did Sudan become a republic?
Answer: 1 January 1956
Hardness

Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood). Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness.

Question: How is hardness determined?
Answer: a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion
Goliath

The Books of Samuel, together with the books of Joshua, Judges and Kings, make up a unified history of Israel which biblical scholars call the Deuteronomistic history. The first edition of the history was probably written at the court of Judah's King Josiah (late 7th century BCE) and a revised second edition during the exile (6th century BCE), with further revisions in the post-exilic period.[3][4] Traces of this can be seen in the contradictions and illogicalities of the Goliath story - to take a few examples, David turns from Saul's adult shield-bearer into a child herding sheep for his father, Saul finds it necessary to send for him when as the king's shield-bearer he should already be beside his royal master, and then has to ask who David is, which sits strangely with David's status at his court.[5] The Goliath story is made up of base-narrative with numerous additions made probably after the exile:[6]

Question: When did the story of David and Goliath take place?
Answer: late 7th century BCE
Capacitor

In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar.[4] Von Kleist's hand and the water acted as conductors, and the jar as a dielectric (although details of the mechanism were incorrectly identified at the time). Von Kleist found that touching the wire resulted in a powerful spark, much more painful than that obtained from an electrostatic machine. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named the Leyden jar, after the University of Leiden where he worked.[5]  He also was impressed by the power of the shock he received, writing, "I would not take a second shock for the kingdom of France."[6]

Question: Who developed the capacitor?
Answer: Ewald Georg von Kleist
Muhajir people

The Muhajir people (also spelled Mahajir and Mohajir) (Urdu: مہاجر‎) are Muslim immigrants, of multi-ethnic origin, and their descendants, who migrated from various regions of India after the independence of Pakistan.[2][3][4][5][6] Although many of them speak different languages at the native level, they are primarily identified as native Urdu speakers and hence are called Urdu-speaking people. The term Muhajirs generally refers to those Muslim migrants from India who settled in urban Sindh.[7]

Question: Where are the Muhajir originally from?
Answer: various regions of India
Raphael (Teenage Mutant Ninja Turtles)

In the 1990 film adaptation, Raphael is voiced by Josh Pais. He speaks with a distinctive tough-sounding New York accent (that was imitated in the later versions of TMNT), and is the turtle whose character is explored most completely. He has a quick temper, uses profanity and verbally challenges his older brother Leonardo. This film focuses more so on his feeling of isolation from his brothers and sense of regret and anger when Splinter is eventually captured from the Shredder. Here, it is established that he shares a closer relationship with news reporter April O'Neil having saved her from the Foot Clan on several occasions.

Question: Who was the oldest turtle in TMNT?
Answer: Leonardo

Akbar

Abu'l-Fath Jalal-ud-din Muhammad Akbar [7] ابو الفتح جلال الدين محمد اكبر (15 October 1542[lower-alpha 1]– 27 October 1605[10][11]), popularly known as Akbar I (IPA:[əkbər]),[12] also as Akbar the Great[13][14][15][16] (Akbar-i-azam اکبر اعظم), was the third Mughal emperor, who reigned from 1556 to 1605. Akbar succeeded his father, Humayun, under a regent, Bairam Khan, who helped the young emperor expand and consolidate Mughal domains in India. A strong personality and a successful general, Akbar gradually enlarged the Mughal Empire to include nearly all of the Indian Subcontinent north of the Godavari river. His power and influence, however, extended over the entire country because of Mughal military, political, cultural, and economic dominance. To unify the vast Mughal state, Akbar established a centralised system of administration throughout his empire and adopted a policy of conciliating conquered rulers through marriage and diplomacy. To preserve peace and order in a religiously and culturally diverse empire, he adopted policies that won him the support of his non-Muslim subjects. Eschewing tribal bonds and Islamic state identity, Akbar strove to unite far-flung lands of his realm through loyalty, expressed through an Indo-Persian culture, to himself as an emperor who had near-divine status.

Question: What years did Akbar the Great live?
Answer: 15 October 1542[lower-alpha 1]– 27 October 1605

The first depiction of a sophisticated robot in a United States film was Gort in The Day the Earth Stood Still.

Question: What science fiction film first featured robots?
Answer: The Day the Earth Stood Still
AFL Grand Final

However, this method had flaws, so the VFL continued to experiment, playing "section" matches after the regular season and then a finals series where first on the ladder played the third team and second met fourth. The winners of these "semi" finals then met in a final to decide the premiership. The first such final was contested in 1898 between the Essendon Football Club and Fitzroy Football Club at the St Kilda Cricket Ground, which Fitzroy won scoring 5.8 (38) to Essendon's 3.5 (23).

Question: When was the first AFL Grand Final?

Oil shale economics

The production cost of a barrel of shale oil ranges from as high as US$95 per barrel to as low US$25 per barrel, although there is no recent confirmation of the latter figure.[4]  The industry is proceeding cautiously, due to the losses incurred during the last major investment into oil shale in the early 1980s, when a subsequent collapse in the oil price left the projects uneconomical.[5]

Question: How much does oil shale sell for?
Answer: as high as US$95 per barrel to as low US$25 per barrel
