Input: Consider Input: Question: How many years after the discovery of pulsars did Lyne retire? Passage:Andrew Geoffrey Lyne FRS (born 13 July 1942) is a British physicist. Lyne is Langworthy Professor of Physics in the School of Physics and Astronomy, University of Manchester, as well as an ex-director of the Jodrell Bank Observatory. Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group. Lyne was educated at The Portsmouth Grammar School, the Royal Naval School, Tal Handaq, Malta and at St. John's College at the University of Cambridge (natural sciences), continuing to the University of Manchester for a PhD in Radio Astronomy. Lyne writes that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."


Output: Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group

Input: Consider Input: Question: How long had the Khanate of Bukhara been in existence when the Russians occupied the territory?

In 1868, Schuyler was a guest of Tolstoi for a week at his estate at Yasnaya Polyana, at the time when Tolstoi was finishing War and Peace. He helped Tolstoi rearrange his library, and went hunting with him. Tolstoi, who was interested in public education in the United States, asked Schuyler for copies of American primers and school textbooks. Schuyler received Tolstoi's permission to translate his novel The Cossacks into English. In 1869, the new Administration of President Ulysses Grant removed Schuyler from his post in Moscow and replaced him with a political appointee. Schuyler was able to obtain a post as consul to the Russian port of Reval (now Tallinn). In November, 1869, President Grant appointed a new Minister to Russia, Andrew Curtin, a former Governor of Pennsylvania who knew nothing of Russia. Curtin was impressed by Schuyler and appointed him as the secretary of the American legation in St. Petersburg, a post which Schuyler held until 1876.
