Q: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Question: What is the current population of Quesnel's birthplace? Passage 1:White Serbia (; Sorbian: Biеło Srbsko), called also Boiki (; Sorbian: Boika), is the name applied to the assumed homeland of the White Serbs, a tribal subgroup of Wends, who were the westernmost group of Early Slavs. They are the ancestors of the modern Serbs and Sorbs. While White Serbia is not explicitly mentioned, Boiki is mentioned in De Administrando Imperio, a 10th-century work by Byzantine Emperor Constantine VII (r. 913–959). According to it the "White Serbs" lived on the "other side of Turkey" (i.e. Hungary), in the area that they called "Boiki" (Bohemia). The area adjacent to it was known as White Croatia, where the White Croats trace their origin.
 Passage 2:The "three now cosmopolitan commensal rodent pest species" (the brown rat, the black rat and the house mouse) have been dispersed in association with humans, partly on sailing ships in the Age of Exploration, and with a fourth species in the Pacific, the Polynesian rat (Rattus exulans), have severely damaged island biotas around the world. For example, when the black rat reached Lord Howe Island in 1918, over 40 percent of the terrestrial bird species of the island, including the Lord Howe fantail, became extinct within ten years. Similar destruction has been seen on Midway Island (1943) and Big South Cape Island (1962). Conservation projects can with careful planning completely eradicate these pest rodents from islands using an anticoagulant rodenticide such as brodifacoum. This approach has been successful on the island of Lundy in the United Kingdom, where the eradication of an estimated 40,000 brown rats is giving populations of Manx shearwater and Atlantic puffin a chance to recover from near-extinction.
 Passage 3:Quesnel was born on 18 January 1765 in Saint-Germain-en-Laye which is now part of Yvelines department near Paris. He enlisted in the 25th Infantry Regiment in the French Royal Army on 18 July 1782. He was promoted to corporal on 18 September 1783, sergeant on 10 October 1784, and farrier on 7 July 1786. After the outbreak of the French Revolution he advanced in rank to sergeant major on 12 September 1789 and sous lieutenant on 15 September 1791. After this, his promotions followed with dizzying swiftness. He became a lieutenant of grenadiers on 19 April 1792 and captain on 1 May of the same year. Promotion to adjutant general chef de bataillon came on 15 May 1793 and adjutant general chef de brigade on 30 September 1793. He became a general of brigade on 26 December 1793.
