Input: Consider Input: Question: In what year did Jordan Roth buy 50% of Jujamcyn? Passage:Landesman was born and raised in St. Louis, Missouri, studied at Colby College and then the University of Wisconsin, Madison (BA English Literature 1969), and the Yale School of Drama (MFA Dramatic Literature and Criticism 1972, DFA 1976). At the Yale School of Drama he became a protégé and friend of Robert Brustein. At the completion of his course work he stayed at Yale for four years as an Assistant Professor. While at Yale, Landesman got to know novelist Jerzy Kosinski and he worked with Kosinski on two of his novels, Being There and The Devil Tree. Landesman was involved as an editor, helping Kosinski, not a native speaker of English, with his English syntax and writing. While at Yale Landesman was also involved in managing a private mutual fund and a racehorse he had bought. In 1977 he left to focus more time on his private investment fund, which he ran for many years. He also got involved in Broadway theater and he was heavily involved in the genesis and development of "Big River" (1985 Tony, Best Musical), a musical based on Huckleberry Finn. Landesman's involvement included persuading Roger Miller to write the music for the show. The show ultimately won seven Tonys and ran for over 1,000 performances on Broadway over two and a half years. This success attracted the attention of James H. Binger who shared two passions with Landesman: Broadway theater and horseracing. Binger owned the Jujamcyn Theatre group of five theatres, four of which were then dark. Binger and Landesman made a deal for Landesman to become President of Jujamcyn in 1987 with the inclusion of an option for Landesman to purchase Jujamcyn upon Binger's death. After taking the helm at Jujamcyn he shifted its business model away from the historical focus of renting of theatre facilities to shows and into a more active posture as a combination of a theater owner and a developer of new plays. Other theater owners have followed this pattern. After joining Jujamcyn Landesman has produced Broadway shows, the most notable of which include: "" (1993 and 1994 Tony, Best Play), and "The Producers" (2001 Tony, Best Musical). Landesman purchased Jujamcyn in 2005 and later sold a 50% interest to Jordan Roth.

Input: Consider Input: Question: What age difference was there between Anderson and his brother? Passage:Anderson was born in Edinburgh in 1832. He studied medicine at the University of Edinburgh, graduating with an MD in 1853. While at University he became interested in botany, and earned a gold medal for the best local collection of plants, and assisted in arranging the Indian herbarium. In 1854 he entered the Bengal medical service, and went to Calcutta. Subsequently he went to Delhi, where he was actively engaged during the mutiny, returning to Calcutta in 1858. His health failing, he came home, and, the steamer being detained at Aden for some days, he made an interesting collection of the plants of that region, upon which he based his ‘Florula Adenensis,’ published in 1860. About this time he returned to India, taking temporary charge of the Calcutta Botanic Garden during the absence of Dr Thomas Thomson, whom he afterwards succeeded as director. His brother, John Anderson was a zoologist.
