Input: Consider Input: 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.

Input: Consider Input: Question: What country did Commandino study in? Passage:Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians.

He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (On the sizes and distances of the Sun and the Moon), Pappus of Alexandria (Mathematical collection), Hero of Alexandria (Pneumatics), Ptolemy of Alexandria (Planisphere and Analemma), Apollonius of Perga (Conics) and Euclid of Alexandria (Elements). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico.

Input: Consider Input: Question: How old was the original owner of the Padres when they joined the ranks of MLB? Passage:In 1969, the Padres joined the ranks of Major League Baseball as one of four new expansion teams, along with the Montreal Expos (now the Washington Nationals), the Kansas City Royals, and the Seattle Pilots (now the Milwaukee Brewers). Their original owner was C. Arnholt Smith, a prominent San Diego businessman and former owner of the PCL Padres whose interests included banking, tuna fishing, hotels, real estate and an airline. Despite initial excitement, the guidance of longtime baseball executives, Eddie Leishman and Buzzie Bavasi as well as a new playing field, the team struggled; the Padres finished in last place in each of its first six seasons in the NL West, losing 100 games or more four times. One of the few bright spots on the team during the early years was first baseman and slugger Nate Colbert, an expansion draftee from the Houston Astros and still the Padres' career leader in home runs.
