Question: How much time was between the periods? Passage:Prior to Nepal’s unification, Srēṣṭha was a collective high-status title given to those Hindu clans referred to as 'Bhāju' (from Sanskrit bhadralok) who served as the key non-Brahmin class of ruling, administrative and merchant class of the Malla courts. From within this broad Srēṣṭha groups are two distinct caste groups. First, they count among them the high-caste aristocratic Kshatriyas, locally pronounced as Chatharīya, who are descended from the nobles and courtiers of the Malla period and consist of the ruling, land-owning and literate Hindu caste group of the Nepal Mandala, which later formed the core of government bureaucracy during the Shah and Rana period. Second, Srēṣṭha title is also attributed to the Pāñchthariya, who now mostly write their surnames as 'Shrestha', who were historically the Hindu merchant clans of the Valley, as opposed to the Buddhist merchant caste of Urāy. These Pāñchthariyas have Vaishya status in the traditional varna framework. Srēṣṭha group has also incorporated in it the socially upward Jyapu farmers and other peasants especially outside the Valley as a means of the Sanskritisation process, although their status is not accepted by the upper-level Srēṣṭha castes.

Question: In which city is the headquarter of the automaker that employed Bagot located? Passage:After the war he spent another eight years organising tourist services between Iraq, Persia (now Iran) and Syria for the Mesopotamian Trading Agency of Ashar, Basrah. His wife may have joined him in 1924. He returned to South Australia in 1926 with the intention of setting up a regular service between Adelaide and Darwin via Oodnadatta and Alice Springs. He conducted a demonstration run with eight men and four women in three Studebaker cars and a Thornycroft truck, leaving Adelaide on 18 May and arrived in Darwin on 3 June; left there on 7 June and returned to Adelaide on 25 June, travelling via Camooweal, Queensland and Marree, South Australia, publicised by Duncan and Fraser (agents for both Thornycroft and Studebaker) and as they were equipped with a short-wave transceiver, gave nightly reports on radio 5CL. Despite a second successful round trip that year, Bagot abandoned his idea of regular service when the Commonwealth Government turned down his application for a subsidy. He found employment with General Motors and in 1930 "Captain Bagot" as he was called by admirers (or "'Alphabetical Bagot' as he was known to the many who disliked him), founded the Citizens' League of South Australia, which opposed Unionism, Communism and the White Australia Policy as benefiting the working classes, yet also opposing Fascism. This was the time of the Great Depression and he also supported the Young People's Employment Council and the Rev. Samuel Forsyth's (1881–1960) Forsyth Industrial Colony "Kuitpo Colony" near Kuitpo Forest, which was training boys as farm workers. The Citizen's League attempted political influence by promising support to political candidates, and was a factor in the election of the Independent candidate George Connor to the Assembly seat of Alexandra in 1934.

Question: Which band member came from the largest town, the drummer or the guitarist? Passage:Casser lived in Liverpool in the late 1950s, having previously worked in the Merchant Navy. As singer and rhythm guitarist, he formed a trio, Cass & the Cassanovas, in May 1959, with singer and guitarist Adrian Barber (born 13 November 1938, Ilkley, Yorkshire), and drummer and singer Brian J. Hudson (born Brian James Hudson, 21 April 1938, Cleveland, Yorkshire). After a few months, Hudson left and was replaced by Johnny Hutchinson (born 18 July 1940, Malta), known as Johnny Hutch. In need of a bass guitarist, Hutchinson then brought in Johnny Gustafson (born 8 August 1942, Liverpool) in December 1959. At that time Gustafson did not have a proper bass guitar so Barber converted an acoustic for him. The group became popular playing a wide range of music, from Latin American music to rock and roll, in dance halls in the Liverpool area. Casser also started his own music club in Liverpool, the Casanova Club, whose guest groups included one known at the time as the "Silver Beetles"; according to some reports, Casser had suggested that they change their name from the earlier spelling of "Beatals" which Casser found "ridiculous". In May 1960 Cass & the Cassanovas took part in auditions in front of leading manager Larry Parnes who was looking for backing bands for his stable of pop singers. The group secured a place as backing group for singer Duffy Power and toured with him. By this time, Casser had begun using the stage names of "Casey Jones" and "Casey Valence".
