Question: Comparing the city in which Ptacek was born with the US city to which his family settled in, which city is larger in size? Passage 1:Secretary of State for Employment and Productivity Barbara Castle introduced an Employed Persons (Health and Safety) Bill in 1970 but the debate around the Bill soon generated a belief that it did not address fundamental issues of workplace safety. In the same year, the Occupational Safety and Health Act was passed into United States federal law. As a result, a committee of inquiry chaired by Lord Robens was established towards the end of Harold Wilson's first government. When the Conservative Party came to power following the 1970 United Kingdom general election, they gave Castle's Bill no parliamentary time, preferring to wait for the Robens Report which was published in 1972. Conservative Secretary of State for Employment William Whitelaw introduced a new Bill on 28 January 1974 but Labour were returned to power in the February 1974 United Kingdom general election and the Bill again lost. The new Labour administration finally secured the passage of a Bill that year.

Bobby Barr became the club's second signing of the summer, joining on a year long deal from Raith Rovers. Ross Forbes was announced as the club's third summer signing on 11 June - signing a season long deal nine years after a loan spell with the club. A day later the club's top scorer from the 2017–18 season, Calum Gallagher, signed a new one-year deal. The week ended with Grant Adam becoming the club's fourth signing of the summer, joining on a one year deal from Forfar Athletic. His arrival was followed by that of striker Rory Loy, who joined after leaving Falkirk, however Danny Handling turned down a new deal with the club to join Scottish League Two side Edinburgh City. Stuart Carswell was the next player to commit himself for another season, signing a new one-year deal after 54 appearances and two goals in his 18 months at the club. The following week defenders Ross Perry and Cammy Ballantyne signed for the club on year-long deals, and they were joined by Ryan Thomson who joined after leaving Stranraer. A day after signing Thomson marked his debut with a goal, which was added to by strikes from Calum Gallagher and Iain Russell (playing as a trialist) as Dumbarton overcame Lowland League side East Kilbride in their first friendly of the season.
 Passage 3:Ptacek was born in East Berlin to a family of Czech and German descent. His family fled East Germany for the United States when he was five years old. They eventually settled in Chicago, where young Ptacek was first exposed to blues music. He moved to Tucson in the early 1970s, where he began his own musical career, most often solo, but sometimes he plugged in and led a trio as Rainer & Das Combo. He co-founded Giant Sandworms with Howe Gelb in the late 1970s. When the band decided to move to New York and became Giant Sand, Ptacek opted to stay in Tucson to make sure that he would not disrupt his then-new family. Although he never became well known in the United States, he became more and more recognized in Europe. ZZ Top guitarist Billy Gibbons was so impressed with the singer-guitarist that he arranged to have Kurt Loder review Ptacek's "Mush Mind Blues" cassette in Rolling Stone. Ptacek later traveled to Houston at the invitation of Billy Gibbons to record at Gibbons' Gold Star Sound Services studio which saw release as "The Texas Tapes" meeting international attention and approval. Robert Plant, similarly impressed, flew Ptacek to England for the sessions for B-sides to supplement the singles from Fate of Nations.

Question: Where was the Ottoman Empire's capital when Mehmed the Conqueror was Sultan? Passage 1:The British eventually recaptured Grappler from the French in September 1809 in the daring raid on Saint-Paul on the Île de Bourbon (now Réunion) from the nearby British-held island of Rodrigues. The British force consisted of a naval squadron under Commodore Josias Rowley and an Army force under Lieutenant Colonel Henry Sheehy Keating. The Army contingent, which consisted of 368 soldiers from the 1st Battalion of the 56th Regiment of Foot under the command Keating, embarked on HMS Nereide under Captain Robert Corbett, Otter under Captain Nesbit Willoughby and the East India Company schooner Wasp under Lieutenant Watkins. The rest of Rowley's squadron, the flagship , and the frigates under Captain Samuel Pym and HMS Boadicea under Captain John Hatley joined off St. Paul. These ships contributed an additional 236 seaman volunteers and Royal Marines to the assault. The entire invasion force then embarked on Nereide, as Corbett had experience with coastline of the Île Bonaparte coastline. On the early morning of 21 September the force seized the port of St. Paul. There they destroyed its defences and recovered a number of British vessels. Nereide and the landing party captured the 44-gun French frigate Caroline, and recovered Grappler as well as the East Indiamen (850 tons (bm) and pierced for 30 guns) and (820 tons (bm) and pierced for 26 guns). The expedition also captured three small merchant vessels (Fanny of 150 tons, and Tres Amis and Creole of 60 tons each), destroyed three others, and burnt one ship that was building on the stocks. The British did not sustain any loss on board the squadron or to their vessels. The British completed the demolition of the different gun and mortar batteries and of the magazines by evening and the whole of the troops, marines, and seamen returned on board their ships.
 Passage 2:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
 Passage 3:From the beginning of the city's history as the western bank of Springfield, Irish families have resided in and contributed to the development of the civics and culture of Holyoke, Massachusetts. Among the first appellations given to the city were the handles "Ireland", "Ireland Parish", or "Ireland Depot", after the village was designated the 3rd Parish of West Springfield in 1786. Initially occupied by a mixture of Yankee English and Irish Protestant families, many of whom belonged to the Baptist community of Elmwood, from 1840 through 1870 the area saw a large influx of Irish Catholic workers, immigrants to the United States, initially from the exodus of the Great Famine. During that period Irish immigrants and their descendants comprised the largest demographic in Holyoke and built much of the early city's infrastructure, including the dams, canals, and factories. Facing early hardships from Anti-Irish sentiment, Holyoke's Irish would largely build the early labor movement of the city's textile and paper mills, and remained active in the national Irish nationalist and Gaelic revival movements of the United States, with the Holyoke Philo-Celtic Society being one of 13 signatory organizations creating the Gaelic League of America, an early 20th century American counterpart of Conradh na Gaeilge.
