instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
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.
answer:
radio

question:
Where is the MLS based?, Context: New York City is home to the headquarters of the National Football League, Major League Baseball, the National Basketball Association, the National Hockey League, and Major League Soccer. The New York metropolitan area hosts the most sports teams in these five professional leagues. Participation in professional sports in the city predates all professional leagues, and the city has been continuously hosting professional sports since the birth of the Brooklyn Dodgers in 1882. The city has played host to over forty major professional teams in the five sports and their respective competing leagues, both current and historic. Four of the ten most expensive stadiums ever built worldwide (MetLife Stadium, the new Yankee Stadium, Madison Square Garden, and Citi Field) are located in the New York metropolitan area. Madison Square Garden, its predecessor, as well as the original Yankee Stadium and Ebbets Field, are some of the most famous sporting venues in the world, the latter two having been commemorated on U.S. postage stamps.
answer:
New York City

question:
What does the third letter in "KANU" refer to?, Context: The first direct elections for native Kenyans to the Legislative Council took place in 1957. Despite British hopes of handing power to "moderate" local rivals, it was the Kenya African National Union (KANU) of Jomo Kenyatta that formed a government. The Colony of Kenya and the Protectorate of Kenya each came to an end on 12 December 1963 with independence being conferred on all of Kenya. The United Kingdom ceded sovereignty over the Colony of Kenya and, under an agreement dated 8 October 1963, the Sultan of Zanzibar agreed that simultaneous with independence for the Colony of Kenya, the Sultan would cease to have sovereignty over the Protectorate of Kenya so that all of Kenya would be one sovereign, independent state. In this way, Kenya became an independent country under the Kenya Independence Act 1963 of the United Kingdom. Exactly 12 months later on 12 December 1964, Kenya became a republic under the name "Republic of Kenya".
answer:
National
