Problem: Given the question: Given the following context:  By the time Smetana completed his schooling, his father's fortunes had declined. Although František now agreed that his son should follow a musical career, he could not provide financial support. In August 1843 Smetana departed for Prague with twenty gulden, and no immediate prospects. Lacking any formal musical training, he needed a teacher, and was introduced by Kateřina Kolářová's mother to Josef Proksch, head of the Prague Music Institute—where Kateřina was now studying. Proksch used the most modern teaching methods, drawing on Beethoven, Chopin, Berlioz and the Leipzig circle of Liszt. In January 1844 Proksch agreed to take Smetana as a pupil, and at the same time the young musician's financial difficulties were eased when he secured an appointment as music teacher to the family of a nobleman, Count Thun.For the next three years, besides teaching piano to the Thun children, Smetana studied theory and composition under Proksch. The works he composed in these years include songs, dances, bagatelles, impromptus and the G minor Piano Sonata. In 1846 Smetana attended concerts given in Prague by Berlioz, and in all likelihood met the French composer at a reception arranged by Proksch. At the home of Count Thun he met Robert and Clara Schumann, and showed them his G minor sonata, but failed to win their approval for this work—they detected too much of Berlioz in it. Meanwhile, his friendship with Kateřina blossomed. In June 1847, on resigning his position in the Thun household, Smetana recommended her as his replacement. He then set out on a tour of Western Bohemia, hoping to establish a reputation as a concert pianist.  answer the following question:  What is the name of the person that had their friendship with Kateřina blossom?

The answer is:
Smetana

input question: Given the following context:  The boards of the covers, previously assumed to be limewood, are now thought to be birch, an unusual wood in later bindings, but one easily available in northern England.  Both have four holes where the binding threads were laced through; the two threads were run round the inner edges of the cover and knotted back at the holes.  The front cover has an additional 12 holes where the ends of the cords for the raised framing lines went through, at the four corners of the two main frames, and the ends of the horizontal bars between the interlace panels and the central vine motif.The stitching of the binding uses "Coptic sewing", that is "flexible unsupported sewing (produced by two needles and thread looping round one another in a figure-of-eight sewing pattern)"  Coptic sewing uses small threads both to attach the leaves together and, knotted together, to attach the pages to the cover boards. Normal Western binding uses thread for the former and thicker cord running across the spine of the book for the latter, with the thread knotted onto the cords.  Coptic sewing is also found in the earliest surviving leather bookbindings, which are from Coptic libraries in Egypt from the 7th and 8th centuries; in particular the design of the cover of one in the Morgan Library (MS M.569) has been compared to the St Cuthbert Gospel.  In the techniques used in the binding, apart from the raised decoration, the closest resemblance is to an even smaller Irish pocket gospel book from some 50 years later, the Cadmug Gospels at Fulda, which is believed to have belonged to Saint Boniface.  This is also in red goatskin, with coloured incised lines, and uses a similar unsupported or cordless stitching technique.  The first appearance of the cords or supports that these "unsupported" bindings lack is found in two other books at Fulda, and they soon became universal in, and characteristic of, Western bookbinding until the arrival of modern machine techniques.  The cords run horizontally across the spine, and are thicker than the threads...  answer the following question:  Which types of boards have four holes where the binding threads were laced through????
output answer: limewood

Please answer this: Given the following context:  The Treaty of San Stefano was signed on 3 March 1878 by Russia and the Ottoman Empire. It was to set up an autonomous Bulgarian principality spanning Moesia, Macedonia and Thrace, roughly on the territories of the Second Bulgarian Empire, and this day is now a public holiday called National Liberation Day. The other Great Powers immediately rejected the treaty out of fear that such a large country in the Balkans might threaten their interests. It was superseded by the Treaty of Berlin, signed on 13 July, which provided for a much smaller state only comprising Moesia and the region of Sofia, leaving large populations of ethnic Bulgarians outside the new country. This significantly contributed to Bulgaria's militaristic foreign affairs approach during the first half of the 20th century.The Bulgarian principality won a war against Serbia and incorporated the semi-autonomous Ottoman territory of Eastern Rumelia in 1885, proclaiming itself an independent state on 5 October 1908. In the years following independence, Bulgaria increasingly militarized and was often referred to as "the Balkan Prussia". It became involved in three consecutive conflicts between 1912 and 1918—two Balkan Wars and World War I. After a disastrous defeat in the Second Balkan War, Bulgaria again found itself fighting on the losing side as a result of its alliance with the Central Powers in World War I. Despite fielding more than a quarter of its population in a 1,200,000-strong army and achieving several decisive victories at Doiran and Monastir, the country capitulated in 1918. The war resulted in significant territorial losses and a total of 87,500 soldiers killed. More than 253,000 refugees from the lost territories immigrated to Bulgaria from 1912 to 1929, placing additional strain on the already ruined national economy.  answer the following question:  Which war resulted in significant territorial losses and a total of 87,500 soldiers killed?

Answer:
World War I
