Teacher: Now, understand the problem? Solve this instance: Question: When was the 17th Dynasty in Egyptian history? Passage 1:With the Treaty of Pozvol, concluded in 1557, the Livonian Confederation had turned to Poland-Lithuania for protection, triggering Ivan IV of Russia's intervention in what was to become the Livonian War. In 1558, Ivan IV had conquered the Dorpat (Tartu) area, annihilating the Bishopric of Dorpat. With the Treaty of Vilnius of 31 August 1559, Gotthard von Kettler, Grand Master of the Livonian Order, had put the order's lands under protection of Polish king and Grand Duke of Lithuania, Sigismund II Augustus. The order ceded about one seventh of its territory, allowed Sigismund to garrison its most important castles, and agreed to share with him any conquests made from Ivan IV. The alliance was intended to neutralize the imminent threat of annexation of the order's lands by Russia, yet despite earning military support from Polish-Lithuanian chancellor Mikołaj "the Black" Radziwiłł, Kettler was defeated in Ergeme (Ermes, 1560) and unable to prevent the occupation of most of Livonia by Russian forces. After the treaty, the disintegrating order agreed to secularization if necessary, and since Sigismund was reluctant to support it militarily, continued its search for a protector at the courts of Denmark-Norway and the Holy Roman Emperor.
 Passage 2:The Egyptian collection consists of about fifty itens, including some objects which stand out in the context of Brazilian museums, due to their quality and rarity. Since these objects are not related to official archeological excavations, their exact place of origin remains largely unknown. The collection includes a number of large pharaonic statuary, in which a head of a Pharaoh in a nemes headdress is the centerpiece. Among the funerary itens, there is a coffin mask with encrusted glass eyes dating back to the 17th Dynasty, and other pieces which reflect the importance of animals in Egyptian rituals, such as a coffin of a mummified cat from the Ptolemaic period. The collection also includes reliefs and fragments of architectural decoration, such as a prominent temple bas-relief of a goddess with the body of a woman and the head of a lioness, dating back to the 3rd Intermediate Period.
 Passage 3:Born in Muzzana del Turgnano, Frossi began his career as a professional footballer with Udinese, and, after a long stay in Serie B (with Padova, Bari, and L’Aquila), he was acquired by Ambrosiana Inter, where he made his debut on 21 June 1936, in Mitropa Cup. After that, Frossi was called up for the 1936 Summer Olympics by Vittorio Pozzo, the coach of the Italian national side, leading the team to the victory of the tournament with his prolific performances. In the following years, Frossi played with Inter from 1936 until 1942, winning the “Scudetto” or league championship, twice in 1938 and 1940, as well as the Coppa Italia in 1939. He scored 49 goals in 147 matches with Inter, 40 of which came in the league, in 125 appearances. During World War II, he later also played with Pro Patria between 1942 and 1943, and Como in 1945, before retiring.
