In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

[Q]: Question: When was the mother of Hagood's daughter born? Passage:Hagood was born in Detroit, Michigan, and first sang at the age of 17 with Benny Carter. He sang with the Dizzy Gillespie Orchestra from 1946 to 1948 and then with Tadd Dameron later in 1948. He recorded two pieces with Thelonious Monk in 1948 and with Miles Davis on the Birth of the Cool sessions in 1950. He then moved to Chicago and later Paris. There in 1960 he had a short-lived marriage to Alice McLeod (later known as Alice Coltrane), who bore him a daughter. Hagood recorded with Guy Lafitte in the 1960s. He moved to Los Angeles, California, in 1965 to 1980. In the early 1980s he returned first to Chicago, and later to the Detroit area.

[Q]: Question: What team did the captain that left Stoke in 2007 go to? Passage:He joined fellow Championship side Stoke City for a £225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.

[Q]: Question: How old was von Braun when his team installed Walter rockerts into experimental aircrafts? 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).
