Passage: The Central Powers launched a crushing offensive on 26 October 1917, spearheaded by the Germans, and achieved a victory at Caporetto . The Italian Army was routed and retreated more than 100 kilometres to reorganise, stabilising the front at the Piave River. Since the Italian Army had suffered heavy losses in the Battle of Caporetto, the Italian Government ordered conscription of the so-called '99 Boys : all males born in 1899 and prior, who were 18 years old or older. In 1918, the Austro-Hungarians failed to break through in a series of battles on the Piave and were finally decisively defeated in the Battle of Vittorio Veneto in October. On 1 November, the Italian Navy destroyed much of the Austro-Hungarian fleet stationed in Pula, preventing it from being handed over to the new State of Slovenes, Croats and Serbs. On 3 November, the Italians invaded Trieste from the sea. On the same day, the Armistice of Villa Giusti was signed. By mid-November 1918, the Italian military occupied the entire former Austrian Littoral and had seized control of the portion of Dalmatia that had been guaranteed to Italy by the London Pact. By the end of hostilities in November 1918, Admiral Enrico Millo declared himself Italy's Governor of Dalmatia. Austria-Hungary surrendered on 11 November 1918.

Passage: While reliable figures are difficult to obtain, estimated global sales of The Hobbit run between 35 and 100 million copies since 1937. In the UK The Hobbit has not retreated from the top 5,000 books of Nielsen BookScan since 1995, when the index began, achieving a three-year sales peak rising from 33,084 (2000) to 142,541 (2001), 126,771 (2002) and 61,229 (2003), ranking it at the 3rd position in Nielsens "Evergreen" book list. The enduring popularity of The Hobbit makes early printings of the book attractive collectors items. The first printing of the first English-language edition can sell for between 6,000 and 20,000 at auction, although the price for a signed first edition has reached over 60,000.
Question: What year were the most copies of the Hobbit sold?

question:
Passage: The war took a heavy toll, especially in the northern British colonies. The losses of Massachusetts men alone in 1745-46 have been estimated as 8% of that colony's adult male population. According to the Treaty of Aix-la-Chapelle, Louisbourg was returned to France three years later, in exchange for the city of Madras in India, captured by the French from the British. This decision outraged New Englanders, particularly Massachusetts colonists who had contributed the most to the expedition The British government eventually acknowledged Massachusetts' effort with a payment of 180,000 after the war, which the province used to retire its devalued paper currency. The peace treaty, which restored all colonial borders to their pre-war status, did little to end the lingering enmity between France, Britain, and their respective colonies, nor did it resolve any territorial disputes. Tensions remained in both North America and Europe, and were reignited with the 1754 outbreak of the French and Indian War in North America, which spread to Europe two years later as the Seven Years' War. Between 1749 and 1755 in Acadia and Nova Scotia, the fighting continued in Father Le Loutre's War.
Question: When was Louisbourg returned to France?
