Article: The universal emergence of atomic hydrogen first occurred during the recombination epoch. At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Since hydrogen readily forms covalent compounds with most non-metallic elements, most of the hydrogen on Earth exists in molecular forms such as in the form of water or organic compounds. Hydrogen plays a particularly important role in acidbase reactions as many acid-base reactions involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) when it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The hydrogen cation is written as though composed of a bare proton, but in reality, hydrogen cations in ionic compounds are always more complex species than that would suggest. As the only neutral atom for which the Schrodinger equation can be solved analytically, study of the energetics and bonding of the hydrogen atom has played a key role in the development of quantum mechanics.

Question: What is the molecular make-up of hydrogen?
Ans: H2

Here is a question about this article: Georgian architecture is the name given in most English-speaking countries to the set of architectural styles current between 1714 and 1830. It is eponymous for the first four British monarchs of the House of HanoverGeorge I, George II, George III, and George IVwho reigned in continuous succession from August 1714 to June 1830. The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture. In America the term "Georgian" is generally used to describe all building from the period, regardless of style; in Britain it is generally restricted to buildings that are "architectural in intention", and have stylistic characteristics that are typical of the period, though that covers a wide range.
What is the answer to this question: Between what years was Georgian architecture in style?
****
So... between 1714 and 1830

The problem: Answer a question about this article:
As the Kulluk oil rig was being towed to the American state of Washington to be serviced in preparation for the 2013 drilling season, a winter storm on 27 December 2012 caused the towing crews, as well as the rescue service, to lose control of the situation. As of 1 January 2013, the Kulluk was grounded off the coast Sitkalidak Island, near the eastern end of Kodiak Island. Following the accident, a Fortune magazine contacted Larry McKinney, the executive director at the Harte Research Institute for Gulf of Mexico Studies at Texas A&M, and he explained that "A two-month delay in the Arctic is not a two-month delay ... A two-month delay could wipe out the entire drilling season."
Following the incident, which magazine contacted Larry McKinney?
****
The answer: Fortune

Problem: Please answer a question about the following article about Beyonce:
At age eight, Beyonce and childhood friend Kelly Rowland met LaTavia Roberson while in an audition for an all-girl entertainment group. They were placed into a group with three other girls as Girl's Tyme, and rapped and danced on the talent show circuit in Houston. After seeing the group, R&B producer Arne Frager brought them to his Northern California studio and placed them in Star Search, the largest talent show on national TV at the time. Girl's Tyme failed to win, and Beyonce later said the song they performed was not good. In 1995 Beyonce's father resigned from his job to manage the group. The move reduced Beyonce's family's income by half, and her parents were forced to move into separated apartments. Mathew cut the original line-up to four and the group continued performing as an opening act for other established R&B girl groups. The girls auditioned before record labels and were finally signed to Elektra Records, moving to Atlanta Records briefly to work on their first recording, only to be cut by the company. This put further strain on the family, and Beyonce's parents separated. On October 5, 1995, Dwayne Wiggins's Grass Roots Entertainment signed the group. In 1996, the girls began recording their debut album under an agreement with Sony Music, the Knowles family reunited, and shortly after, the group got a contract with Columbia Records.
What large record company recorded Beyonce's group's first album?
A: Sony Music

Question: Read this and answer the question

After the failed union of Sweden and Norway of 13191365, the pan-Scandinavian Kalmar Union was instituted in 1397. The Swedes were reluctant members of the Danish-dominated union from the start. In an attempt to subdue the Swedes, King Christian II of Denmark had large numbers of the Swedish aristocracy killed in the Stockholm Bloodbath of 1520. Yet this measure only led to further hostilities, and Sweden broke away for good in 1523. Norway, on the other hand, became an inferior party of the union and remained united with Denmark until 1814.

When was the Kalmar Union formed?
Answer: 1397

There are many styles of mandolin, but four are common, the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin. The round-back has a deep bottom, constructed of strips of wood, glued together into a bowl. The carved-top or arch-top mandolin has a much shallower, arched back, and an arched topboth carved out of wood. The flat-backed mandolin uses thin sheets of wood for the body, braced on the inside for strength in a similar manner to a guitar. Each style of instrument has its own sound quality and is associated with particular forms of music. Neapolitan mandolins feature prominently in European classical music and traditional music. Carved-top instruments are common in American folk music and bluegrass music. Flat-backed instruments are commonly used in Irish, British and Brazilian folk music. Some modern Brazilian instruments feature an extra fifth course tuned a fifth lower than the standard fourth course.
Which form of music do Neapolitan mandolins feature?
European classical music and traditional music.
