Article: All current USB On-The-Go (OTG) devices are required to have one, and only one, USB connector: a micro-AB receptacle. Non-OTG compliant devices are not allowed to use the micro-AB receptacle, due to power supply shorting hazards on the VBUS line. The micro-AB receptacle is capable of accepting both micro-A and micro-B plugs, attached to any of the legal cables and adapters as defined in revision 1.01 of the micro-USB specification. Prior to the development of micro-USB, USB On-The-Go devices were required to use mini-AB receptacles to perform the equivalent job.

Question: Why are the Non-OTG compliant devices not allowed to use the micro-AB receptacle?
Ans: power supply shorting hazards on the VBUS line


Article: The Cork area has seen improvements in road infrastructure in recent years. For example, the Cork South Link dual carriageway was built in the early 1980s, to link the Kinsale Road roundabout with the city centre. Shortly afterwards, the first sections of the South Ring dual carriageway were opened. Work continued through the 1990s on extending the N25 South Ring Road, with the opening of the Jack Lynch Tunnel under the River Lee being a significant addition. The Kinsale Road flyover opened in August 2006 to remove a bottleneck for traffic heading to Cork Airport or Killarney. Other projects completed at this time include the N20 Blackpool bypass and the N20 Cork to Mallow road projects. The N22 Ballincollig dual carriageway bypass, which links to the Western end of the Cork Southern Ring road was opened in September 2004. City Centre road improvements include the Patrick Street project - which reconstructed the street with a pedestrian focus. The M8 motorway links Cork with Dublin.

Question: When was the Cork South Link dual carriageway built?
Ans: 1980s


Article: In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated façade so that this might be achieved at a later date.

Question: What was the name of the building style that resulted from the use of brick?
Ans: Brick Gothic, is called "Backsteingotik"


Article: From September 1823 to 1826 Chopin attended the Warsaw Lyceum, where he received organ lessons from the Czech musician Wilhelm Würfel during his first year. In the autumn of 1826 he began a three-year course under the Silesian composer Józef Elsner at the Warsaw Conservatory, studying music theory, figured bass and composition.[n 3] Throughout this period he continued to compose and to give recitals in concerts and salons in Warsaw. He was engaged by the inventors of a mechanical organ, the "eolomelodicon", and on this instrument in May 1825 he performed his own improvisation and part of a concerto by Moscheles. The success of this concert led to an invitation to give a similar recital on the instrument before Tsar Alexander I, who was visiting Warsaw; the Tsar presented him with a diamond ring. At a subsequent eolomelodicon concert on 10 June 1825, Chopin performed his Rondo Op. 1. This was the first of his works to be commercially published and earned him his first mention in the foreign press, when the Leipzig Allgemeine Musikalische Zeitung praised his "wealth of musical ideas".

Question: During what years did Frédéric visit the Warsaw Lyceum for lessons?
Ans:
1823 to 1826
