Question:
Further work on MPEG audio was finalized in 1994 as part of the second suite of MPEG standards, MPEG-2, more formally known as international standard ISO/IEC 13818-3 (a.k.a. MPEG-2 Part 3 or backwards compatible MPEG-2 Audio or MPEG-2 Audio BC), originally published in 1995. MPEG-2 Part 3 (ISO/IEC 13818-3) defined 42 additional bit rates and sample rates for MPEG-1 Audio Layer I, II and III. The new sampling rates are exactly half that of those originally defined in MPEG-1 Audio.  This reduction in sampling rate serves to cut the available frequency fidelity in half while likewise cutting the bitrate by 50%. MPEG-2 Part 3 also enhanced MPEG-1s audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel. An MP3 coded with MPEG-2 results in half of the bandwidth reproduction of MPEG-1 appropriate for piano and singing.

How many suites of MPEG standards were there?

Answer:
2


Question:
Henry suffered a serious setback in 1437 after the failure of an expedition to capture Tangier, having encouraged his brother, King Edward, to mount an overland attack from Ceuta. The Portuguese army was defeated and only escaped destruction by surrendering Prince Ferdinand, the king's youngest brother. After the defeat at Tangier, Henry retired to Sagres on the southern tip of Portugal where he continued to direct Portuguese exploration until his death in 1460. In 1443 Prince Pedro, Henry's brother, granted him the monopoly of navigation, war and trade in the lands south of Cape Bojador. Later this monopoly would be enforced by the Papal bulls Dum Diversas  and Romanus Pontifex , granting Portugal the trade monopoly for the newly discovered countries, laying the basis for the Portuguese empire. A major advance which accelerated this project was the introduction of the caravel in the mid-15th century, a ship that could be sailed closer to the wind than any other in operation in Europe at the time. Using this new maritime technology, Portuguese navigators reached ever more southerly latitudes, advancing at an average rate of one degree a year. Senegal and Cape Verde Peninsula were reached in 1445. The first feitoria trade post overseas was established then under Henry's directions, in 1445 on the island of Arguin off the coast of Mauritania, to attract Muslim traders and monopolize the business in the routes traveled in North Africa, starting the chain of Portuguese feitorias along the coast. In 1446, Álvaro Fernandes pushed on almost as far as present-day Sierra Leone and the Gulf of Guinea was reached in the 1460s.

How many years did Henry live after his failure to capture Tangier?

Answer:
23


Question:
During the closing ceremony of the 2013 Southeast Asian Games, the SEAGF Flag was formally handed over from Myanmar to Singapore. This was followed by a song and dance section highlighting Singapore as the next venue. On 27 June 2014, a series of festivities were held at the Singapore Sports Hub, including a fireworks display, to mark the one year countdown to the games. The Sports Hub Community Open House was held in conjunction with the launch to introduce the new sports facilities to the general public. The countdown to the games began on 15 February 2014 with a launch party at the Gardens by the Bay, where the logo, theme and mascot were also introduced. 800 Nanyang Polytechnic students organised a major countdown event on 11 April 2015 to mark the final 50 days in a few days, where about 4,000 people turned up to attend a concert and a sports carnival. On 16 April 2015, the 50-day countdown began with various organisations stacking a number each through a video tribute. This included: Nanyang Polytechnic and Ang Mo Kio residents and Changkat Primary School , London School of Business and Finance Singapore , Compassvale Primary School , Development Bank of Singapore , National Kidney Foundation , CWT Limited , SportCares , Park View Primary School , Sport Singapore  and 41st Battalion Singapore Armoured Regiment . Other organisations were:

How many organisations had video tributes?

Answer:

Question:
Theobald I of Lorraine died in May 1220 under mysterious circumstances, and to seal the peace the 19-year-old Theobald IV of Champagne married Lorraine's 16-year-old widow, Gertrude of Dagsburg.  Duke Theobald I's brother Matthew II, who succeeded in Lorraine, made peace and swore fealty to Blanche.  Bishop William of Langres was elected archbishop of Reims in 1219, resulting in his fortuitous departure from the conflict.  Erard renounced any claim on Champagne on 2 November 1221 and Philippa in April 1222.  In return for renouncing his claims, Erard received a substantial cash settlement.  The last rebel baron, Erard II of Chacernay, swore his renewed loyalty to Theobald IV in March 1222.  Two months later in May 1222, Theobald IV reached the age of maturity and began his reign as count, and the triumphant Countess-Regent Blanche withdrew to the Cistercian convent of Argensolles for her retirement.

How many regions did Erard renounce any claim of?

Answer:
2
