Input: Consider Input: Question: How long is the river along which the Polanie remained in situ? Passage:The Poles are the most numerous of the West Slavs and occupy what some believe to be the original homeland of the Slavic peoples. While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea. There is no other European nation centred to such an extent on one river. The establishment of a Polish state is often identified with the adoption of Christianity by Mieszko I in 966 CE (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. In 1025 CE, Poland became a kingdom. In 1569, Poland cemented a long association with the Grand Duchy of Lithuania by signing the Union of Lublin, forming the PolishLithuanian Commonwealth. The PolishLithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.

Output: While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea

Input: Consider Input: Question: Which is the oldest city that borders Garden Grove? Passage:West Grove, officially recognized as the West Grove Business District by the City of Garden Grove, and sometimes called West Garden Grove, is a neighborhood in the city of Garden Grove, located in Orange County, California, United States. West Grove encompasses the pene-exclave western portion of the city of Garden Grove. It is bordered to the north by Cypress, to the west by Los Alamitos and Seal Beach, to the south by Westminster, and to the east by Stanton, and connected to the rest of Garden Grove by a narrow strip along Garden Grove Boulevard. It includes the entire 92845 ZIP Code, which is designated as the areas west of Knott Avenue to the Seal Beach and Los Alamitos city borders, and the industrial area east of Knott Avenue to the Stanton border. The community is more "affluent" than the rest of Garden Grove, with a median income $25,000 greater than the main body of the city. There is also less crime, a lower poverty rate, and the population density is lower compared to the rest of Garden Grove. As of the 2010 Census, 16,333 people reside in West Grove.

Output: It is bordered to the north by Cypress, to the west by Los Alamitos and Seal Beach, to the south by Westminster, and to the east by Stanton, and connected to the rest of Garden Grove by a narrow strip along Garden Grove Boulevard

Input: Consider Input: Question: What was the name of the convicted rapist/murderer's mother that Don Dunstan advocated for? Passage:In the late 1950s, Dunstan became well known for his campaign against the death penalty being imposed on Max Stuart, who was convicted of rape and murder of a small girl. He harried Premier Thomas Playford IV aggressively over the matter, creating an uproar over what he saw as an unfair process. Playford eventually relented, and appeared shaken thereafter; the event was seen as a turning point in the Liberal and Country League's decline, and Labor gained momentum. During Labor's time in opposition, Dunstan was prominent in securing some reforms in Aboriginal rights, and was at the forefront of Labor abandoning the White Australia Policy. Labor conducted an extensive campaign in marginal LCL seats at the 1965 election, resulting in 21 of 39 seats, with Frank Walsh and the Labor Party taking power and Dunstan becoming Attorney-General. The LCL opposition changed leaders and installed the young Steele Hall, worrying Labor as the elderly Walsh appeared bumbling in contrast. This resulted in Labor replacing Walsh with Dunstan. Despite maintaining a much larger vote over the LCL, Labor lost two seats at the 1968 election, with the LCL forming government with support of an independent. Dunstan responded by increasing his attacks on the Playmander and was able to convincingly sustain Playmander attacks with the effect of convincing the LCL into watering down the malapportionment. Again with little change in Labor's vote but with the Playmander removed, Labor won 27 of 47 seats at the 1970 election. With a fairer seat and boundary system in place, Dunstan won three more elections, in 1973, 1975 and 1977.
Output: In the late 1950s, Dunstan became well known for his campaign against the death penalty being imposed on Max Stuart, who was convicted of rape and murder of a small girl
