National Football League television blackout policies

From 1973 through 2014, the NFL maintained a blackout policy that states that a home game cannot be televised in the team's local market if 85%  of the tickets are not sold out 72hours prior to its start time. This makes the NFL the only major professional sports league in the US that requires teams to sell out tickets in order to broadcast a game on television locally. Although nationally televised games in the other leagues are often blacked out on the national networks on which the game is airing in the local markets of the participating teams, they can still be seen on the local broadcast TV station or regional sports network that normally holds their local/regional broadcast rights. The league blackout policy has been suspended on a year-to-year basis since 2015.

Question: When did the NFL first introduce its television blackout policies?
Answer: 1973
Crime film

Crime films, in the broadest sense, are a cinematic genre inspired by and analogous to the crime fiction literary genre. Films of this genre generally involve various aspects of crime and its detection. Stylistically, the genre may overlap and combine with many other genres, such as drama or gangster film[1], but also include comedy, and, in turn, is divided into many sub-genres, such as mystery, suspense or noir.

Question: What is a crime drama?
Answer: a cinematic genre inspired by and analogous to the crime fiction literary genre
History of Tibet

Some archaeological data suggests archaic humans passed through Tibet at the time India was first inhabited, half a million years ago.[1] Modern humans first inhabited the Tibetan Plateau at least twenty-one thousand years ago.[2] This population was largely replaced around 3000 BC by Neolithic immigrants from northern China. However, there is a "partial genetic continuity between the Paleolithic inhabitants and the contemporary Tibetan populations".[2]

Question: How old is Tibet?
Answer: twenty-one thousand years ago
Mitrailleuse

A mitrailleuse (French pronunciation:​[mitʁajøz]; from French mitraille, "grapeshot") is a type of volley gun with multiple barrels of rifle calibre that can fire either multiple rounds at once or several rounds in rapid succession. The earliest true mitrailleuse was invented in 1851 by Belgian Army captain Fafschamps, 10 years before the advent of the Gatling gun. It was followed by the Belgian Montigny mitrailleuse in 1863. Then the French 25 barrel "Canon à Balles", better known as the Reffye mitrailleuse, was adopted in great secrecy in 1866. It became the first rapid-firing weapon deployed as standard equipment by any army in a major conflict when it was used during the Franco-Prussian War of 1870–71. A steel block containing twenty-five 13mm (.51 calibre) centre-fire cartridges was locked against the breech before firing. With the rotation of a crank, the 25 rounds were discharged in rapid succession. The sustainable firing rate of the Reffye mitrailleuse was 100 rounds per minute. The maximum effective range of the Reffye mitrailleuse was about 2000 yards; a distance which placed their batteries beyond the reach of Prussian Dreyse needle rifle fire. Reffye mitrailleuses were deployed in six gun batteries and were manned by artillery personnel. They were not infantry support weapons, but rather a form of special artillery.

Question: When was the first mitrailleuse developed?
Answer: 1851
Three Laws of Robotics

In The Rest of the Robots, published in 1964, Asimov noted that when he began writing in 1940 he felt that "one of the stock plots of science fiction was... robots were created and destroyed their creator. Knowledge has its dangers, yes, but is the response to be a retreat from knowledge? Or is knowledge to be used as itself a barrier to the dangers it brings?" He decided that in his stories robots would not "turn stupidly on his creator for no purpose but to demonstrate, for one more weary time, the crime and punishment of Faust."[2]

Question: When did Issac Asimov publish his rules on robotics?
Answer: 1964
Broiler

A broiler (Gallus gallus domesticus) is any chicken that is bred and raised specifically for meat production.[1] Many typical broilers have white feathers and yellowish skin.  Most commercial broilers reach slaughter-weight between four[2] and seven weeks of age, although slower growing breeds reach slaughter-weight at approximately 14 weeks of age. Due to extensive breeding selection for rapid early growth and the husbandry used to sustain this, broilers are susceptible to several welfare concerns, particularly skeletal malformation and dysfunction, skin and eye lesions and congestive heart conditions. Management of ventilation, housing, stocking density and in-house procedures must be evaluated regularly to support good welfare of the flock. The breeding stock (broiler-breeders) do grow to maturity but also have their own welfare concerns related to the frustration of a high feeding motivation and beak trimming. Broilers are usually grown as mixed-sex flocks in large sheds under intensive conditions.

Question: What is the most common breed of chicken used for commercial meat production?
Answer: A broiler
Tokyo Dome

It was built on the site of the Velodrome, adjacent to the predecessor ballpark, Kōrakuen Stadium. It has a maximum total capacity of 57,000 depending on configuration, with an all-seating configuration of 42,000.[3][4][5]

Question: When was the Tokyo Dome built?
Answer: March 17, 1988
List of leading Thoroughbred racehorses

It is common to compare racehorses on multiple factors such as their overall race record, the quality of the horses they beat and the brilliance of their wins. Comparison of raw times is generally unreliable between horses of different eras or even in different countries due to a variety of factors such as the racing surface and the pace at which the race is run. Timeform ratings, introduced in 1948,[1] and Beyer Speed Figures, introduced in the United States in 1992, are relatively recent attempts to compensate for such variables.[2] Thoroughbred Winning Brew holds the Guinness world record for the fastest speed for a Thoroughbred racehorse, at 70.76km/h (43.97mph) over two furlongs,[3] although Quarter Horses attain higher speeds over shorter distances than Thoroughbreds.[4] Looking at average speeds for longer distances may be misleading as many races are run with a slow initial pace followed by a sprint in the stretch drive.

Question: How fast is the fastest horse in the world?
Answer: 70.76km/h
Climate of Mars

Differing in situ values have been reported for the average temperature on Mars,[21] with a common value being −63°C (210K; −81°F).[22][23]  Surface temperatures may reach a high of about 20°C (293K; 68°F) at noon, at the equator, and a low of about −153°C (120K; −243°F) at the poles.[24] Actual temperature measurements at the Viking landers' site range from −17.2°C (256.0K; 1.0°F) to −107°C (166K; −161°F). The warmest soil temperature estimated by the Viking Orbiter was 27°C (300K; 81°F).[25] The Spirit rover recorded a maximum daytime air temperature in the shade of 35°C (308K; 95°F), and regularly recorded temperatures well above 0°C (273K; 32°F), except in winter.[26]

Oakum

Oakum can be used to seal cast iron pipe drains. After setting the pipes together, workers pack oakum into the joints, then pour molten lead into the joint to create a permanent seal. The oakum swells and seals the joint, the "tar" in the oakum prevents rot, and the lead keeps the joint physically tight. Today, modern methods, such as rubber seals (for example, gaskets or o-rings) are more common.[5]

Question: Why is tar used to seal cracks?
Answer: The oakum swells and seals the joint, the "tar" in the oakum prevents rot, and the lead keeps the joint physically tight

Cerebellum

The unusual surface appearance of the cerebellum conceals the fact that most of its volume is made up of a very tightly folded layer of gray matter: the cerebellar cortex. Each ridge or gyrus in this layer is called a folium. It is estimated that, if the human cerebellar cortex were completely unfolded, it would give rise to a layer of neural tissue about 1meter long and averaging 5centimeters wide—a total surface area of about 500square cm, packed within a volume of dimensions 6cm × 5cm × 10cm.[8] Underneath the gray matter of the cortex lies white matter, made up largely of myelinated nerve fibers running to and from the cortex. Embedded within the white matter—which is sometimes called the arbor vitae (tree of life) because of its branched, tree-like appearance in cross-section—are four deep cerebellar nuclei, composed of gray matter.[10]

Question: How large is the human cerebellum?
Answer: total surface area of about 500square cm

National Flower of the Republic of China

The National Flower of the Republic of China was officially designated as the plum blossom by the Executive Yuan of the Republic of China on July 21, 1964.[1] The plum blossom, known as the meihua (Chinese:梅花; pinyin:méihuā), is symbol for resilience and perseverance in the face of adversity, because plum blossoms often bloom most vibrantly even amidst the harsh winter snow.[2][3] As the plum tree can usually grow for a long time, ancient trees are found throughout China. Huangmei county (Yellow Mei) in Hubei features a 1,600-year-old plum tree from the Jin Dynasty which is still flowering. The three stamens represents Dr. Sun Yat-sen's Three Principles of the People, while the five petals symbolize the five branches of the government: Executive Yuan, Legislative Yuan, Judicial Yuan, Examination Yuan and Control Yuan.[1][3] The flower has also been proposed to be one of the national flowers for the People's Republic of China.[4]

Kingdom of Aksum

The Kingdom of Aksum (also known as the Kingdom of Axum, or the Aksumite Empire) was an ancient kingdom located in what is now Tigray Region (northern Ethiopia) and Eritrea.[2][3]. Axumite Emperors were powerful sovereigns, styling themselves King of kings, king of Aksum, Himyar, Raydan, Saba, Salhen, Tsiyamo, Beja and of Kush.[4] Ruled by the Aksumites, it existed from approximately 100 AD to 940 AD. The polity was centered in the city of Axum and grew from the proto-Aksumite Iron Age period around the 4th century BC to achieve prominence by the 1st century AD.  Aksum became a major player on the commercial route between the Roman Empire and Ancient India. The Aksumite rulers facilitated trade by minting their own Aksumite currency, with the state establishing its hegemony over the declining Kingdom of Kush. It also regularly entered the politics of the kingdoms on the Arabian Peninsula and eventually extended its rule over the region with the conquest of the Himyarite Kingdom. The Manichaei prophet Mani (died 274 AD) regarded Axum as one of the four great powers of his time, the others being Persia, Rome, and China.[2][5]

Question: How long did the Aksumites rule in Ethiopia?
Answer: 100 AD to 940 AD
Red blood cell

Adult humans have roughly 20–30 trillion red blood cells at any given time, constituting approximately 70% of all cells by number.[18] Women have about 4–5 million red blood cells per microliter (cubic millimeter) of blood and men about 5–6 million; people living at high altitudes with low oxygen tension will have more. Red blood cells are thus much more common than the other blood particles: there are about 4,000–11,000 white blood cells and about 150,000–400,000 platelets per microliter.

Question: How many red blood cells are in the human body?
Answer: 20–30 trillion
