Question: Polin succeeded ambassador Antoine de Rincon  in Constantinople. In early 1542, Polin successfully negotiated the details of a Franco-Ottoman alliance for the Italian War of 1542-1546, with the Ottoman Empire promising to send 27,500 troops against the territories of the Spanish king Ferdinand, as well as 110 galleys against Charles, while France promised to attack Flanders, harass the coasts of Spain with a naval force, and send 40 galleys to assist the Turks for operations in the Levant. Polin tried to convince Venice to join the alliance, but in vain. The execution of the alliance would most notably lead to the Franco-Ottoman Siege of Nice in 1543. In July 1543, Polin sailed on board the Ottoman fleet of Barbarossa to the Île Saint-Honorat in the Lérins Islands off Cannes on 5 July 1543, only to find very little ready for the offensive on the French side. Polin went to see king Francis I of France to obtain troops, which led to the Siege of Nice in August 1543. Polin supervised the wintering of the Ottomans at Toulon. 
Question: Which country agreed to send more galleys?

Answer: Ottoman Empire

Question: As of 2013, Ratanakiri Province had a population of approximately 184,000. Its population nearly doubled between 1998 and 2013, largely due to internal migration. In 2013, Ratanakiri made up 1.3% of Cambodia's total population; its population density of 17.0 residents per square kilometer was just over one fifth the national average. About 70% of the province's population lives in the highlands; of the other 30%, approximately half live in more urbanized towns, and half live along rivers and in the lowlands, where they practice wetland rice cultivation and engage in market activities. Banlung, the provincial capital located in the central highlands, is by far the province's largest town, with a population of approximately 25,000. Other significant towns include Veun Sai in the north and Lomphat in the south, with populations of 2,000 and 3,000 respectively.In 2013, 37% of Ratanakiri residents were under age 15, 52% were age 15 to 49, 7% were age 50 to 64, and 3% were aged 65 or older; 49.7% of residents were male, and 50.3% were female. Each household had an average of 4.9 members, and most households (85.6%) were headed by men.While highland peoples have inhabited Ratanakiri for well over a millennium, lowland peoples have migrated to the province in the last 200 years. As of 2013, various highland groups collectively called Khmer Loeu made up approximately half of Ratanakiri's population, ethnic Khmers made up 36%, and ethnic Lao made up 10%. Within the Khmer Loeu population, 35% were Tampuan as of 1998, 24% were Jarai, 23% were Kreung, 11% were Brou, 3% were Kachok, and 3% were Kavet, with other groups making up the remaining one percent. There are also very small Vietnamese, Cham, and Chinese minorities.  Though the official language of Ratanakiri (like all of Cambodia) is Khmer, each indigenous group speaks its own language. Less than 10% of Ratanakiri's indigenous population can speak Khmer fluently.
