You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: Between Duke Albert and the man he wanted to liberate, which one is older? Passage 1:After the war, Norden wrote material for comedian Dick Bentley, before meeting Frank Muir (who wrote for comic actor Jimmy Edwards) in 1947; they were brought together by producer Ted Kavanagh. Muir and Norden's first joint venture was a radio show for both performers, Take it from Here!, which they scripted from 1948 to 1959. They went on to write many successful radio and television scripts, including Whack-O! (1956–1960) and three series of Faces of Jim (1961–1963) which were vehicles for Jimmy Edwards. They also wrote the satirical sketch Balham, Gateway to the South for the BBC Third Programme. The sketch, which had originally been broadcast in 1948 as part of a comedy series called The Third Division and which featured actor Robert Beatty, was later performed by Peter Sellers for his LP, The Best of Sellers (1959). In the early 1960s, Muir and Norden wrote the sitcom Brothers in Law, an early series featuring Richard Briers, and its spin-off Mr Justice Duncannon.
 Passage 2: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."
 Passage 3:In 1488 Duke Albert III "the bold" of Saxony, the Margrave of Meissen, campaigned to against the rebellious Flanders, aiming to liberate Emperor Maximilian I, who was held prisoner by the citizens of Bruges. As a reward, Maximilian I appointed Albert III governor of the Netherlands and, as compensation for the cost incurred, Albert was appointed in 1498 as hereditary governor of Frisia, with an understanding that he'd have to subdue Frisia by force of arms before he could take up this post. After subduing the Frisians, Albert III rushed to Leipzig to attend the Diet, the Frisians revolted and laid siege to Franeker, where Albert's second son, Henry had taken up the post of governor. Albert rushed back to Frisia and freed Henry. He then conquered Groningen before dying in Emden on 12 September 1500. Henry inherited the post of governor of Frisia. However, the Frisians kept resisting his rule and he resigned on 30 May 1505 in favour of his brother George, in exchange for two districts in the Ore Mountains.
