Extract the answer to the question from the following context. Question: what machine is mentioned first? Context: Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

Extract the answer to the question from the following context. Question: What students is City of Bath School limited to? Context: Some of the county's secondary schools have specialist school status. Some schools have sixth forms and others transfer their sixth formers to colleges. Several schools can trace their origins back many years, such as The Blue School in Wells and Richard Huish College in Taunton. Others have changed their names over the years such as Beechen Cliff School which was started in 1905 as the City of Bath Boys' School and changed to its present name in 1972 when the grammar school was amalgamated with a local secondary modern school, to form a comprehensive school. Many others were established and built since the Second World War. In 2006, 5,900 pupils in Somerset sat GCSE examinations, with 44.5% achieving 5 grades A-C including English and Maths (compared to 45.8% for England).

Extract the answer to the question from the following context. Question: What did West originally say to defend his actions? Context: On September 13, 2009, during the 2009 MTV Video Music Awards while Taylor Swift was accepting her award for Best Female Video for "You Belong with Me", West went on stage and grabbed the microphone to proclaim that Beyonce's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently removed from the remainder of the show for his actions. When Beyonce later won the award for Best Video of the Year for "Single Ladies (Put a Ring on It)", she called Swift up on stage so that she could finish her acceptance speech. West was criticized by various celebrities for the outburst, and by President Barack Obama, who called West a "jackass". In addition, West's VMA disruption sparked a large influx of Internet photo memes with blogs, forums and "tweets" with the "Let you finish" photo-jokes. He posted a Tweet soon after the event where he stated, "Everybody wanna booooo me but I'm a fan of real pop culture... I'm not crazy y'all, I'm just real." He then posted two apologies for the outburst on his personal blog; one on the night of the incident, and the other the following day, when he also apologized during an appearance on The Jay Leno Show. After Swift appeared on The View two days after the outburst, partly to discuss the matter, West called her to apologize personally. Swift said she accepted his apology.
Ans: "Everybody wanna booooo me but I'm a fan of real pop culture... I'm not crazy y'all, I'm just real."
