question: What was the capital of the Kingdom to which George Khevenhüller build a city-fortress? 
answer: Zagreb
context: Title: George Parsons (shipbuilder)
  Passage: George Parsons was born in Poole, the son of George Parsons, and was baptised at St James, Poole, 21 September 1729.  His father moved to Portsmouth to take up a position as a shipwright in the Royal Dockyard in 1740.  George junior began as a Quarter Boy entering 18 June 1744.  He continued in the Royal Dockyard until, as a 2nd shipwright he was discharged 6 April 1763.  His move to Bursledon therefore probably occurred later that year and certainly by 1764.  His first employer there was a shipowner, Thomas Cooper, and a few years later, Philemon Ewer, a descendant of the pre-eminent local shipbuilder of the previous generation.  He almost certainly moved into his own yard by 1774 at Bursledon Point on the Hamble, though the advertisement in 1776 for 'a good burthensome well built Sloop, about 30 tons, just finished' suggested this might have been built in partnership with Ewer.  By late 1778 he was ready to build on his own account when a Navy Board letter of 19 December refers to an offer from him to build 'a Ship of 32 guns'.
  Title: Kingdom of Croatia (Habsburg)
  Passage: The Kingdom of Croatia (Croatian: "Kraljevina Hrvatska"; Latin: "Regnum Croatiae" Hungarian: "Horvát Királyság" German: "Königreich Kroatien" ) was an administrative division that existed between 1527 and 1868 within the Habsburg Monarchy (also known between 1804 and 1867 as the Austrian Empire).  The Kingdom was a part of the Lands of the Crown of St. Stephen, but was subject to direct Imperial Austrian rule for significant periods of time, including its final years.  Its capital was Zagreb.
  Title: George Khevenhüller
  Passage: Georg von Khevenhüller (, also spelled as Gjuro or George Khevenhiller; 22 April 1533 – 9 September 1587) was a Carinthian nobleman of the Khevenhüller dynasty.  Though a dedicated Protestant by faith, he served as a governor of the Catholic House of Habsburg for several decades.  He is also famous for building the city-fortress of Karlovac in Croatia.
  Title: Light Railways Act 1896
  Passage: The Light Railways Act 1896 (59 & 60 Vict.  c.48) was an Act of the Parliament of the United Kingdom of Great Britain and Ireland (as it then was).  Before the Act each new railway line built in the country required a specific Act of Parliament to be obtained by the company that wished to construct it, which greatly added to the cost and time it took to construct new railways.  The economic downturn of the 1880s had hit agriculture and rural communities in the United Kingdom especially hard and the government wished to facilitate the construction of railways in rural areas, especially to facilitate the transport of goods.  The 1896 Act defined a class of railways which did not require specific legislation to construct – companies could simply plan a line under the auspices of the new Act, and, having obtained a Light Railway Order, build and operate it.  By reducing the legal costs and allowing new railways to be built quickly the government hoped to encourage companies to build the new 'light railways' in areas of low population and industry that were previously of little interest to them.
  Title: Let's Build a World Together (song)
  Passage: "Let's Build a World Together" is a love song by George Jones and Tammy Wynette.  It was the married couple's fourth single together on Epic Records and became the title track of their fourth LP in 1973.  Although the song expressed the promise of new love, 1973 would be the beginning of the end as far as their marriage was concerned, with Wynette filing for divorce for the first time in August of that year.  Their tumultuous personal life, which often made the gossip papers, coupled with their flawless vocal harmonies on love songs like "Let's Build a World Together," mesmerized their fans.  Indeed, the more their lives deteriorated, the bigger hits the couple would have, especially after their 1975 divorce.  However, "Let's Build a World Together" was not a hit, only making it to #32 on the "Billboard" singles chart.  Interestingly, co-writer George Richey would become Wynette's fifth husband.
