Document 2: Military history of Italy during World War I: On 3 May 1915 Italy officially revoked the Triple Alliance. In the following days Giolitti and the neutralist majority of the Parliament opposed declaring war, while nationalist crowds demonstrated in public areas for it. (The nationalist poet Gabriele D'Annunzio called this period le radiose giornate di Maggio -- ``the sunny days of May ''). Giolitti had the support of the majority of Italian parliament so on 13 May Salandra offered his resignation to King Victor Emmanuel III, but then Giolitti learned that the London Pact was already signed: fearful of a conflict between the Crown and the Parliament and the consequences on both internal stability and foreign relationships, Giolitti accepted the fait accompli, declined to succeed as prime minister and Salandra's resignation was not accepted. On 23 May, Italy declared war on Austria - Hungary. This was followed by declarations of war on the Ottoman Empire (21 August 1915, following an ultimatum of 3 August), Bulgaria (19 October 1915) and the German Empire (28 August 1916).
Document 3: Elsa Hosk: Growing up in Sweden, Hosk was presented with offers to model during high school after her father submitted photographs to various modeling agencies in Sweden when she was 13; she began modeling at 14. She did some modeling in high school but decided to primarily concentrate on her studies instead (she did some notable work with Guess and other companies however). After graduating, she decided to pursue a career in the Swedish women's basketball league. Hosk has commented that the level of play in the Swedish professional basketball league was not on par with the WNBA, and that interest in the sport was not as great in Sweden as in the United States. Although she ultimately abandoned professional basketball for modeling, Hosk has said that the intense rigor of practices (8 per week when playing basketball) and travel helped prepare her for the physical and travel demands of the modeling world.After playing professional basketball for two years, she began receiving many job offers and soon moved to New York City to begin modeling full-time. Some writers have speculated that her work with Victoria's Secret was what brought her into the top tier fashion world, but Hosk also identifies her work with photographer Ellen von Unwerth in campaigns for Guess.She is ranked 15th on the Top Sexiest Models list by models.com. She opened the Victoria's Secret Fashion Show in 2016 and wore the Swarovski outfit in 2017.
