Input: Sumer
The Sumerian city-states rose to power during the prehistoric Ubaid and Uruk periods. Sumerian written history reaches back to the 27th century BC and before, but the historical record remains obscure until the Early Dynastic III period, c. the 23rd century BC, when a now deciphered syllabary writing system was developed, which has allowed archaeologists to read contemporary records and inscriptions. Classical Sumer ends with the rise of the Akkadian Empire in the 23rd century BC. Following the Gutian period, there is a brief Sumerian Renaissance in the 21st century BC, cut short in the 20th century BC by Semitic Amorite invasions. The Amorite "dynasty of Isin" persisted until c. 1700 BC, when Mesopotamia was united under Babylonian rule. The Sumerians were eventually absorbed into the Akkadian (Assyro-Babylonian) population.

During what periods did the Sumerican city-states rise to power?
Output: prehistoric Ubaid and Uruk

Input: Article: All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, etudes, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.

Now answer this question: Chopin wrote some music to lyrics, what language were the lyrics?

Output: Polish

Article: In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red. Two possibilities have been suggested for the origin of the white sleeves. One story reports that Chapman noticed a supporter in the stands wearing a red sleeveless sweater over a white shirt; another was that he was inspired by a similar outfit worn by the cartoonist Tom Webster, with whom Chapman played golf. Regardless of which story is true, the red and white shirts have come to define Arsenal and the team have worn the combination ever since, aside from two seasons. The first was 196667, when Arsenal wore all-red shirts; this proved unpopular and the white sleeves returned the following season. The second was 200506, the last season that Arsenal played at Highbury, when the team wore commemorative redcurrant shirts similar to those worn in 1913, their first season in the stadium; the club reverted to their normal colours at the start of the next season. In the 200809 season, Arsenal replaced the traditional all-white sleeves with red sleeves with a broad white stripe.

Question: What brighter shade of red did Chapman adopt?
Ans: pillar box red

Here is a question about this article: Once Pan had the audacity to compare his music with that of Apollo, and to challenge Apollo, the god of the kithara, to a trial of skill. Tmolus, the mountain-god, was chosen to umpire. Pan blew on his pipes, and with his rustic melody gave great satisfaction to himself and his faithful follower, Midas, who happened to be present. Then Apollo struck the strings of his lyre. Tmolus at once awarded the victory to Apollo, and all but Midas agreed with the judgment. He dissented and questioned the justice of the award. Apollo would not suffer such a depraved pair of ears any longer, and caused them to become the ears of a donkey.
What is the answer to this question: Who was the mountain-god?
****
So... Tmolus

The fighter aircraft of the USAF are small, fast, and maneuverable military aircraft primarily used for air-to-air combat. Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as Full Scale Aerial Targets (FSAT) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF has 2,025 fighters in service as of September 2012.
What aircraft is used by the US Air Demonstration group The Thunderbirds?
****
The answer: F-16

Sichuan consists of two geographically very distinct parts. The eastern part of the province is mostly within the fertile Sichuan basin (which is shared by Sichuan with Chongqing Municipality). The western Sichuan consists of the numerous mountain ranges forming the easternmost part of the Qinghai-Tibet Plateau, which are known generically as Hengduan Mountains. One of these ranges, Daxue Mountains, contains the highest point of the province Gongga Shan, at 7,556 metres (24,790 ft) above sea level.
What makes up majority of the eastern Sichuan province?
****
The answer:
Sichuan basin
