Q: 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.
 Passage 2:June started with striker Mark Stewart having the second year of his contract cancelled. Following this Turnberry Homes signed a new two-year deal to continue as the club's shirt sponsors. 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.
