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.

[Q]: Question: How many years had Gary Tallon been playing professionally by the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.

[Q]: Question: What was the capital of the Republic of Rawanda? Passage:In 1962, the Belgian mandate of Ruanda-Urundi received independence, creating the Republic of Rwanda and the Kingdom of Burundi. Both states had traditionally had monarchies dominated by the Tutsi ethnic group over a Hutu ethnic majority but Rwanda's monarchy was abolished by a political revolution in 1959-61. In the first years of independence, Burundi seemed to have achieved a balance between ethnic groups which brought members of the different ethnic groups into government, moderated in part by the mwami (king) Mwambutsa IV who was popular with all groups but was himself Tutsi. Both Tutsi, Hutu and Ganwa were part of the dominant political party, the Union for National Progress (Union pour le Progrès national, UPRONA). In October 1961, shortly before the date scheduled for independence, the Burundian Prime Minister Prince Louis Rwagasore was assassinated, raising ethnic tensions in the country. After a period of rule by Tutsi prime ministers, Mwambutsa appointed Burundi's first Hutu leader, Pierre Ngendandumwe, but Ngendandumwe was assassinated in January 1965 by a Rwandan Tutsi. Elections held in May 1965 took place in an atmosphere of strong ethnic tension. Hutu candidates gained a majority, but Mwambutsa deposed the Hutu Prime Minister Joseph Bamina and instead installed a Tutsi candidate, Léopold Biha, in October 1965.

[Q]: 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 Peenemünde 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, 400 kg (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).
