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.
Q: Question: When was the last prince-bishop of Warmia born? Passage 1:By the First Partition of Poland in 1772, Warmia was annexed by the Kingdom of Prussia; the properties of the Archbishopric of Warmia were secularized by the Prussian state. In 1773 Warmia was merged with the surrounding areas into the newly established province of East Prussia. Ignacy Krasicki, the last prince-bishop of Warmia as well as Enlightenment Polish poet, friend of Frederick the Great (whom he did not give homage as his new king), was nominated to the Archbishopric of Gnesen (Gniezno) in 1795. After the last partition of Poland and during his tenure as Archbishop of Poland and Prussian subject he was ordered by Pope Pius VI to teach his Catholic Poles to 'stay obedient, faithful, and loving to their new kings', Papal brief of 1795. The Prussian census in 1772 showed a total population of 96,547, including an urban population of 24,612 in 12 towns. 17,749 houses were listed and the biggest city was Braunsberg (Braniewo).
 Passage 2:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 – 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Académiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.
 Passage 3:The Chronicon Angliae Petriburgense is a 14th-century chronicle written in Medieval Latin at Peterborough Abbey, England, covering events from 604 to 1368, although the original manuscript ends with an entry for 868, and the remainder was added in the 17th century. It survives as part of a composite manuscript volume held at the British Library with the mark Cotton Claudius A.v, in which it appears on folios 2–45. An edition of the Chronicon was published in 1723 by Joseph Sparke, in a collection of English histories by various writers. According to John Allen Giles, in the preface to his own edition published by the Caxton Society in 1845, the Chronicon was attributed by both Simon Patrick and Henry Wharton to John of Caleto (or "Caux"), who was an abbot of Peterborough (1250–1262). Giles reported a marginal note in the manuscript making a similar attribution, besides a similar note at the beginning of the manuscript stating that it belonged to Peterborough Abbey. However, Giles observed that this manuscript attribution was "comparatively modern", and regarded the chronicle's author as unknown. In Giles's view, the Chronicon is "extremely valuable both on account of the numerous facts which it contains, and for the [700 years] which it embraces."
