Problem: According to the traditional narrative, several companions of Muhammad served as scribes and were responsible for writing down the revelations. Shortly after Muhammad's death, the Quran was compiled by his companions who wrote down and memorized parts of it. These codices had differences that motivated the Caliph Uthman to establish a standard version now known as Uthman's codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning.
By what name is the first standardized version of the Quran known?
The answer is the following: Uthman's codex


Richmond has a humid subtropical climate (Köppen Cfa), with hot and humid summers and generally cool winters. The mountains to the west act as a partial barrier to outbreaks of cold, continental air in winter; Arctic air is delayed long enough to be modified, then further warmed as it subsides in its approach to Richmond. The open waters of the Chesapeake Bay and Atlantic Ocean contribute to the humid summers and mild winters. The coldest weather normally occurs from late December to early February, and the January daily mean temperature is 37.9 °F (3.3 °C), with an average of 6.0 days with highs at or below the freezing mark. Downtown areas straddle the border between USDA Hardiness zones 7B and 8A, and temperatures seldom lower to 0 °F (−18 °C), with the most recent subzero (°F) reading occurring on January 28, 2000, when the temperature reached −1 °F (−18 °C). The July daily mean temperature is 79.3 °F (26.3 °C), and high temperatures reach or exceed 90 °F (32 °C) approximately 43 days out of the year; while 100 °F (38 °C) temperatures are not uncommon, they do not occur every year. Extremes in temperature have ranged from −12 °F (−24 °C) on January 19, 1940 up to 107 °F (42 °C) on August 6, 1918.[a]
About how many days a year does the temperature in Richmond go above 32 degrees Celsius?
43


Input: Dwight D. Eisenhower
Since the 19th century, many if not all presidents were assisted by a central figure or "gatekeeper", sometimes described as the President's Private Secretary, sometimes with no official title at all. Eisenhower formalized this role, introducing the office of White House Chief of Staff – an idea he borrowed from the United States Army. Every president after Lyndon Johnson has also appointed staff to this position. Initially, Gerald Ford and Jimmy Carter tried to operate without a chief of staff, but each eventually appointed one.

From where did Eisenhower get the idea of a White House Chief of Staff?
Output: United States Army


Input: Article: Before the advent of the ASA system, the system of Weston film speed ratings was introduced by Edward Faraday Weston (1878–1971) and his father Dr. Edward Weston (1850–1936), a British-born electrical engineer, industrialist and founder of the US-based Weston Electrical Instrument Corporation, with the Weston model 617, one of the earliest photo-electric exposure meters, in August 1932. The meter and film rating system were invented by William Nelson Goodwin, Jr., who worked for them and later received a Howard N. Potts Medal for his contributions to engineering.

Now answer this question: Who is credited with creating the film and meter system?

Output: William Nelson Goodwin, Jr.


Article: Strasbourg's status as a free city was revoked by the French Revolution. Enragés, most notoriously Eulogius Schneider, ruled the city with an increasingly iron hand. During this time, many churches and monasteries were either destroyed or severely damaged. The cathedral lost hundreds of its statues (later replaced by copies in the 19th century) and in April 1794, there was talk of tearing its spire down, on the grounds that it was against the principle of equality. The tower was saved, however, when in May of the same year citizens of Strasbourg crowned it with a giant tin Phrygian cap. This artifact was later kept in the historical collections of the city until it was destroyed by the Germans in 1870 during the Franco-Prussian war.

Question: Who ruled the city with an iron hand?
Ans: Eulogius Schneider


Input: United States Air Force
Beyond combat flight crew personnel, perhaps the most dangerous USAF jobs are Explosive Ordnance Disposal (EOD), Combat rescue officer, Pararescue, Security Forces, Combat Control, Combat Weather, Tactical Air Control Party, and AFOSI agents, who deploy with infantry and special operations units who disarm bombs, rescue downed or isolated personnel, call in air strikes and set up landing zones in forward locations. Most of these are enlisted positions augmented by a smaller number of commissioned officers. Other career fields that have seen increasing exposure to combat include civil engineers, vehicle operators, and Air Force Office of Special Investigations (AFOSI) personnel.

What do some of these special missions in the USAF who deploy with the infantry do?
Output:
rescue downed or isolated personnel
