instruction:
In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.
question:
Question: Do more than 10,000 people live in the city where Bonnaroo is held? Passage:After the release of Levitate, his first full-length album, in 2011, he began to play shows and festivals around the country. Starting in 2012 with a US tour that saw him hit the road with The M Machine, he continued on to play the Coachella Valley Music and Arts Festival, more commonly known as Coachella, a festival that takes place in April in Indio, California. After Coachella he played Electric Forest Festival in Rothbury, Michigan in June 2012. He then played Lollapalooza Music Festival in Chicago, Illinois Grant Park (Chicago) in early August 2012 before Heading to New York City to play Electric Zoo Festival at the end of August 2012 on Randall's Island. He then kicked off his very own solo Night Vision Tour 2012 in September by releasing a 30-minute mix entitled Night Vision Tour Mix 2012. He has also played at Bonnaroo Music Festival in June 2013 in Manchester, Tennessee.

question:
Question: What time period did George II serve as king? Passage:Born to an aristocratic family in Ithaca, Metaxas took part in the Greco-Turkish War of 1897 and the Balkan Wars (191213), quickly rising through the ranks of the Hellenic Army. A royalist during the National Schism, Metaxas unsuccessfully opposed Prime Minister Eleftherios Venizelos and Greece's entry in World War I; as a result, he was exiled to Corsica in 1917. On his return, Metaxas moved into politics and founded the Freethinkers' Party, but had only limited success under the Hellenic Republic. The Greek monarchy was restored in 1935, and Metaxas was appointed Prime Minister in April 1936. On 4 August 1936, with the support of King George II, Metaxas initiated a self-coup and established an authoritarian, nationalist and anti-communist regime.

question:
Question: Who was in charge of Messerschmitt when the Heinkel He 176 first flew? Passage:At the same time that Walter was developing submarine engines, he was also applying his ideas to rocketry. The high-pressure gas mixture created by the rapid decomposition of hydrogen peroxide could not only be used in a turbine, but if simply directed out of a nozzle, created considerable thrust. Wernher von Braun's rocketry team working at Peenemunde expressed interest in Walter's ideas, and in 1936 began a programme of installing Walter rockets into aircraft. The experimental results obtained by von Braun created interest among Germany's aircraft manufacturers, including Heinkel and Messerschmitt, and in 1939, the Heinkel He 176 became the first aircraft to fly on liquid-fuelled rocket power alone. This type of engine went on to become the cornerstone of the Messerschmitt Me 163 rocket-powered fighter, when married to Alexander Lippisch's revolutionary airframe design. Throughout the course of World War II, Walter's aircraft engines became increasingly powerful and refined. The original design of simply decomposing hydrogen peroxide was soon changed to its use as an oxidizer (much like dinitrogen tetroxide would be used later) when combined with a hydrazine/methanol true rocket fuel designated C-Stoff, into the hot, high-pressure gases, and in later, never-deployed developments, a second, 400kg (880 lb) thrust "cruising" combustion chamber, nicknamed a Marschofen, was added below the main chamber to allow for more precise control of the engine. Versions of this engine were intended to power a variety of aircraft design proposals and missile projects and was also licence-built in Japan (see HWK 109-509).
