Input: Consider Input: Question: Which of the seas that the Sibiryakov sailed to was larger? Passage:A. Sibiryakov sailed on 28 June 1932 from the Krasny (previously Sobornoy) docks in Arkhangelsk, crossed the Kara Sea and chose a northern, unexplored way around Severnaya Zemlya to the Laptev Sea. In September, after calling at Tiksi and the mouth of the Kolyma, the propeller shaft broke and the icebreaker drifted for 11 days. However, A. Sibiryakov crossed the Chukchi Sea using improvised sails and arrived in the Bering Strait in October. A. Sibiryakov reached the Japanese port of Yokohama after 65 days, having covered more than in the Arctic seas. This was regarded as a heroic feat of Soviet polar seamen and Chief of Expedition Otto Schmidt and Captain Vladimir Voronin were received with many honors at their return to Russia.

Input: Consider Input: Question: Who was the writer of Richard III? Passage:After leaving the Academy, German continued to teach at Wimbledon School and to play the violin in orchestras at various London theatres, including the Savoy. In 1888, an introduction by conductor Alberto Randegger to theatre manager Richard Mansfield led to German's appointment as conductor and musical director at the Globe Theatre in London. There he improved the orchestra and began providing incidental music for the theatre's lavish productions, starting with Richard III in 1889. This music was well received (The Times called for a concert suite to be arranged), and the overture soon became popular in concert halls. This eventually led to other incidental music commissions that gained success. In 1892, German composed music for a production of Henry Irving's version of Henry VIII at the Lyceum Theatre, London, where he incorporated elements of traditional old English dance. Within a year, sheet music of the dance numbers from the play's score had sold 30,000 copies. German was by then in great demand to write music for plays. His commissions included Henry Arthur Jones's The Tempter in 1893, Johnston Forbes-Robertson's Romeo and Juliet at the Lyceum in 1895, Herbert Beerbohm Tree's productions of As You Like It (1896) and Much Ado about Nothing (1898), and Anthony Hope's English Nell (later known as Nell Gwynn) in 1900, starring Marie Tempest.
