Input: Consider Input: Question: Were the Oz books the only books L. Frank Baum ever wrote? Passage:The Land of Ev is a fictional country in the Oz books of L. Frank Baum and his successors. Its exact location is unclear between text and maps. The Road to Oz states that Ev is to the north of the Land of Oz, and in Ozma of Oz, Princess Ozma of Oz and her procession enter the Munchkin Country and meet the King of the Munchkins upon leaving the palace at Evna, the capital city. Subsequent books place Ev nearer to the Winkie Country, and the map on the endpapers of Tik-Tok of Oz shows the Munchkin Country as having no northern border with the desert that surrounds Oz, as a thin strip of the Gillikin Country extends even farther east than most of the Munchkin Country. This map depicts Ev as a small country to the northwest (the compass rose is reversed) of Oz, with the Dominions of the Nome King as a separate area. James E. Haff and Dick Martin's map, following the text, place the Nome Kingdom under an Ev that takes up the entire portion allotted to the Nome King's dominions on Baum's map.

Input: Consider Input: Question: Which Cuffe family member had held public office for the greatest number of years by the time Elizabeth Cuffe married Thomas Pakenham? Passage:Alice Aungier, sister of the first and second Earl of Longford, married Sir James Cuffe, Member of Parliament for County Mayo. Their son Francis Cuffe also represented County Mayo in the Irish Parliament. Francis's son Michael Cuffe sat as Member of Parliament for County Mayo and Longford Borough. Michael's daughter Elizabeth Cuffe married Thomas Pakenham, of Pakenham Hall, just outside Castlepollard, County Westmeath, in 1739. Thomas represented Longford Borough in the Irish House of Commons. In 1756 the Longford title held by his wife's ancestors was revived when he was raised to the Peerage of Ireland as Baron Longford, in the County of Longford. In 1785 the earldom was also revived when Elizabeth was created Countess of Longford in her own right in the Peerage of Ireland. Lord Longford was succeeded by his eldest son, the second Baron. He represented Longford County in the Irish Parliament. He died aged only 49 and was succeeded by his son, the third Baron. In 1794 the third baron also succeeded his grandmother as second Earl of Longford. Lord Longford sat in the British House of Lords as one of the 28 original Irish Representative Peers. In 1821 he was created Baron Silchester, of Silchester in the County of Southampton, in the Peerage of the United Kingdom, which gave him and his descendants an automatic seat in the House of Lords.
