Question: In what year was the house the Vogtei went to after the Lenzburg family established? Passage:The first mention of modern Hagglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromunster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hagglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.

Question: How many teams were a part of the league that ran from 2001-2003 and featured many World Cup stars? Passage:The first women's professional soccer league in the U.S. formed after the success of the 1999 Women's World Cup. The Women's United Soccer Association (WUSA) ran from 20012003 and featured many of the World Cup stars, including Mia Hamm, Michelle Akers and Brandi Chastain. Its successor Women's Professional Soccer (WPS) ran from 20092012. Currently, the National Women's Soccer League (NWSL) is the top professional league in the country and was formed in 2012. The NWSL season runs from spring to early fall (typically April October). In 2017, A&E Networks bought an equity stake in the league and broadcasts a game of the week on Lifetime, and formerly streamed all games online via the go90 platform. During the 2018 season, the NWSL moved some of the games originally scheduled to air on Lifetime to evening slots on ESPNews (both channels being part of the Disney family), and when go90 owner Verizon shut down that platform at the end of July, the NWSL streamed the games that were intended for go90 on its own website.

Question: How long did the battle in which Union troops deployed artillery westward to the Peach Orchard using Wheatfield Road last? Passage:During the Battle of Gettysburg, the dirt Wheatfield Road was used by various Union and Confederate troops (e.g., Crawford's Third Division of Pennsylvania Reserves), and Union troops deployed artillery westward to the Peach Orchard using the road. In 1884, the Round Top Branch's wye with double spurs and station was built at the east end of Wheatfield Road, and in 1894 the Gettysburg Electric Railway was laid along a west portion of the road (trolleys also crossed the east end near Round Top Station). In 1895, the Commonwealth of Pennsylvania ceded jurisdiction of Wheatfield Road to the War Department, and in 1900 two cast iron identification tablets were placed to label the road. The Gettysburg Electric Railway tracks were removed from the Wheatfield Road in 1917 and the road was repaired in 1931. The Wheatfield Road was resurfaced with asphalt west of Sykes Avenue in 1933, and completed "from the Rosensteel pavilion to the Taneytown road" in 1940 by the McMillan Woods Civilian Conservation Corps camp.
