Article: By 1353, the three original cantons had joined with the cantons of Glarus and Zug and the Lucerne, Zurich and Bern city states to form the "Old Confederacy" of eight states that existed until the end of the 15th century. The expansion led to increased power and wealth for the federation. By 1460, the confederates controlled most of the territory south and west of the Rhine to the Alps and the Jura mountains, particularly after victories against the Habsburgs (Battle of Sempach, Battle of Nafels), over Charles the Bold of Burgundy during the 1470s, and the success of the Swiss mercenaries. The Swiss victory in the Swabian War against the Swabian League of Emperor Maximilian I in 1499 amounted to de facto independence within the Holy Roman Empire.

Question: Which century did the Old Confederacy of the eight states exist until?
Ans: end of the 15th century

Article: The immediate predecessors of MP3 were "Optimum Coding in the Frequency Domain" (OCF), and Perceptual Transform Coding (PXFM). These two codecs, along with block-switching contributions from Thomson-Brandt, were merged into a codec called ASPEC, which was submitted to MPEG, and which won the quality competition, but that was mistakenly rejected as too complex to implement. The first practical implementation of an audio perceptual coder (OCF) in hardware (Krasner's hardware was too cumbersome and slow for practical use), was an implementation of a psychoacoustic transform coder based on Motorola 56000 DSP chips.

Question: What was the name of the codec that OCF, PFXM and other contributes merged into?
Ans: ASPEC

Article: About 20% of pupils at Eton receive financial support, through a range of bursaries and scholarships. The recent Head Master, Tony Little, said that Eton is developing plans to allow any boy to attend the school whatever his parents' income and, in 2011, said that around 250 boys received "significant" financial help from the school. In early 2014, this figure had risen to 263 pupils receiving the equivalent of around 60% of school fee assistance, whilst a further 63 received their education free of charge. Little said that, in the short term, he wanted to ensure that around 320 pupils per year receive bursaries, and that 70 were educated free of charge, with the intention that the number of pupils receiving financial assistance would continue to increase. These comparatively new developments will run alongside long-established courses that Eton has provided for pupils from state schools, most of them in the summer holidays (July and August). Launched in 1982, the Universities Summer School is an intensive residential course open to boys and girls throughout the UK who attend state schools, are at the end of their first year in the Sixth Form, and are about to begin their final year of schooling. The Brent-Eton Summer School, started in 1994, offers 40-50 young people from the London Borough of Brent, an area of inner-city deprivation, an intensive one-week residential course, free of charge, designed to help bridge the gap between GCSE and A-level. In 2008, Eton helped found the Eton, Slough, Windsor and Hounslow Independent and State School Partnership (ISSP), with six local state schools. The ISSP's aims are "to raise pupil achievement, improve pupil self-esteem, raise pupil aspirations and improve professional practice across the schools". Eton also runs a number of choral and English language courses during the summer months.

Question: How many students attended Eton free of charge in 2014?
Ans:
63
