Question: What major landmarks are in the district Rohrbach went to in 1803? Passage:Rohrbach was first mentioned in 795 as Roorbah when a local noble, Heribold, gave his lands in Madiswil to the church in Rohrbach. In the 9th century some land around the village was given to the Abbey of St. Gall. The Abbey established an administrator in Rohrbach to manage their lands in the Oberaargau region. Since the Abbey was an Imperial Abbey, the administrator and the landholders on the Abbey's land had immunity from the local count's court and could only be arrested or tried by the Abbey court. At the beginning of the 14th century the bailiwick and the low court of the local Barons of Ruti. Between 1314 and 1370 both offices were held by the Count of Signau and after 1371 by the Count of Grünenberg. The Grünenberg Counts incorporated the village into their personal territory. Hermann of Eptingen then acquired the rule over the village by marriage. He supported the Austrian Habsburgs in the Old Zürich War (1440–46) and lost the village to a Bernese army. After the war, the village was returned to his wife in 1449. In 1504 Bern bought the entire village from Hermann's decedents. In 1505 the village was incorporated into the bailiwick of Wangen. However, Rohrbach retained several special privileges. They were exempt from forced labor for the bailiff and in wars they marched under the banner of the city of Bern. After the 1798 French invasion it was part of the District of Langenthal in the Helvetic Republic and in 1803 it went to the District of Aarwangen.

Question: What was his first victory of the year? Passage:Race 1 was held on Saturday 10 May. Mark Winterbottom took his second race victory of the year, a surprisingly comfortable win ahead of the HRT pair of Mark Skaife and Garth Tander. Tander was pushed hard by Steven Richards and Craig Lowndes. A collision at race start saw Jason Bright touch Greg Murphy who in turn made contact with Michael Caruso, sending Bright and Caruso out of control towards turn 7, where crossing the track Caruso struck Shane van Gisbergen. The incident triggered a safety car. Jamie Whincup and Will Davison charged through to seventh and eight positions from poor qualifying places. James Courtney was fighting amongst that group but fading rear tyres led Courtney to attempt defensive moves that raised the ire of race control, leading to first the bad sportsmanship flag, then a black flag drive through penalty which dropped him down field.

Question: How long had Hastoe been in existence when Llewelyn-Davies became the Baroness of Hastoe? Passage:Llewelyn-Davies entered the civil service in 1940 and served in the Ministry of War Transport, the Foreign Office, the Air Ministry and the Commonwealth Relations Office. She resigned to contest the Wolverhampton South-West parliamentary seat for Labour during the 1951 general election, but was defeated by the incumbent Conservative Enoch Powell. She subsequently unsuccessfully contested the Wandsworth Central seat in 1955 and 1959, but didn't stand for parliament again. With support of those in the Wilson government and the backing of close friend Richard Crossman, who described her in his diaries as "the real politician" when her husband was elevated to the peerage, she was created a life peer as Baroness Llewelyn-Davies of Hastoe, of Hastoe in the County of Hertfordshire on 29 August 1967. She went on to serve as a Government whip in the House of Lords between 1969 and 1970, and as Opposition Deputy Chief Whip from 1972. In 1973 she was elected Chief Whip, becoming the first woman to take charge of a whip's office in either house. On the return of the Labour Party to government in 1974 she became Captain of the Gentlemen-at-Arms (Government Chief Whip). In 1975, she became a Privy Counsellor. From 1979 to 1982 she was once again Opposition Chief Whip. From 1982 to 1987, she was Principal Deputy Chairman of Committees in the House of Lords, an office carrying with it the role of Chairman of the European Communities Committee.
