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.

Input: Consider Input: Question: During what years was "Joliet" Jake Blues in prison? Passage:Blues vocalist and petty criminal "Joliet" Jake Blues is paroled on good behavior grounds from Joliet Correctional Center after serving three years of a five-year sentence, and is picked up by his blood brother Elwood in his Bluesmobile, a battered, decommissioned police car. Elwood demonstrates its capabilities by jumping an open drawbridge. The brothers visit the Roman Catholic orphanage where they were raised, and learn from Sister Mary "the Penguin" Stigmata and old friend Curtis that it will be closed unless $5,000 in property taxes is collected. Jake offers to steal the money, but Sister Mary is offended. During a sermon by the Reverend Cleophus James at the Triple Rock Baptist Church, Jake has another idea: they can re-form their band, the Blues Brothers, which disbanded while Jake was in prison, and raise the money to save the orphanage.

Input: Consider Input: Question: How many season did the HBO show that forced Dean Winters to leave Law & Order last? Passage:For the lead roles, Christopher Meloni was cast as Detective Elliot Stabler and Mariska Hargitay was cast as Detective Olivia Benson after they auditioned together. Hargitay, who had to move from Los Angeles to New York when she got the role, said she was able to do this on short notice because she was already planning on moving to New York to pursue a Broadway career. The squad commander role was filled by Dann Florek, who had portrayed Captain Don Cragen for the first three seasons on the original Law & Order and later reprised his role in . He joined the cast on the condition that he not be asked to audition. Richard Belzer was cast as Detective John Munch, continuing his role from the series . In Belzer's words, he was cast because "Dick Wolf and Tom Fontana got drunk at a party". Halfway through the season, Richard Belzer reprised his role of Munch in , which briefly shows his character out on a case in his SVU context in New York. At Belzer's insistence, his character was partnered with Brian Cassidy, who was portrayed by Dean Winters. However, Winters' contractual obligation to the HBO series Oz forced him to leave halfway through the season. Michelle Hurd, who portrayed Detective Monique Jeffries, filled Winters' void for the remainder of the season, and was at that point added to the main credits.

Input: Consider Input: Question: What was the age of Issai Schur when Bieberbach wrote a book with him? Passage:Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Uber die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
