You will be given a definition of a task first, then some input of the task.
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: Which was established first, Camp Chase or Camp Thomas? Passage 1:Henry I Kőszegi, a significant figure of the era of so-called "feudal anarchy", was killed in the Battle of Föveny in September 1274. His power and wealth in Western Transdanubia were largely inherited by his two elder sons, Nicholas and Ivan, who divided their heirdom and the most valuable domains among themselves in 1279. Henry was excluded from the contract, only his wine growers were mentioned, to whom they were assigned certain vineyards in Moson and Pozsony counties. Historians János Karácsonyi and Attila Zsoldos considered Henry was granted lands in Slavonia from his brothers sometime before 1279, during an unequal sharing; his first lands laid in Varaždin County, the northwestern part of the province. There, it is presumable, he owned the castles of the late "Farkas of Zagorje" from the beginning, including Krapina (Korpona). Subsequently, the forts of Belec, Kostel, Vrbovec (Orbolc) and Oštrc (Oszterc) also belonged to his branch's property, but the time and circumstances of their acquisition are unknown. From these lands and castles on the southwestern corner of the kingdom, Henry expanded his influence over the territory, which was ruled by Joachim Gutkeled prior to that, between the rivers Drava and Sava (called Slavonia superior, "Upper Slavonia"), in the upcoming decades, and was considered the most powerful lord in the region by the extinction of the Árpád dynasty in 1301. For instance, he acquired the castles of Susica (later Szentgyörgy, present-day Đurđevac in Croatia) and Koprivnica (Kapronca) in Križevci County. During their family contract, Nicholas and Ivan did not renounce the possibility of their expansion into Slavonia, they both possessed landholdings and castles in the province too. In their agreement at Dubica on 20 April 1278, the Kőszegis and the Babonići divided the spheres of interest in Slavonia between each other. Henry and his brothers renounced territorial claims from all areas south of the river Sava (Slavonia inferior, "Lower Slavonia") in favor of Stephen Babonić and his clan, who acknowledged the Kőszegis' power north of the river at the same time.
 Passage 2:Camp Chase was an American Civil War training and prison camp established in May 1861, on land leased by the U.S. Government. It replaced the much smaller Camp Jackson which was established by Ohio Governor William Dennison Jr as a place for Ohio's union volunteers to meet. It originally operated from a city park. The main entrance was on the National Road west of Downtown Columbus, Ohio. Boundaries of the camp were present-day Broad Street (north), Hague Avenue (east), Sullivant Avenue (south), and near Westgate Avenue (west). Named for former Ohio Governor, Salmon P. Chase, who was Lincoln's Secretary of the Treasury; it was a training camp for Ohio volunteer army soldiers, a parole camp, a muster outpost, and later a prisoner-of-war camp. The nearby Camp Thomas served as a similar base for the Regular Army. As many as 150,000 Union soldiers and 25,000 Confederate prisoners passed through its gates from 1861–1865. By February 1865, over 9,400 men were held at the prison. More than 2,200 Confederates are buried in the Camp Chase Cemetery. Western Virginia and Kentucky civilians suspected of actively supporting secession, including former three-term United States Congressman Richard Henry Stanton were held at the facility. The prison camp also held Confederates captured during Morgan's Raid in 1863, including Col. Basil W. Duke.
 Passage 3:The Dunckers returned to Germany in 1947, settling first in Rostock and later in Bernau, just outside Berlin. Home was now part of the Soviet occupation zone, relaunched in October 1949 as the German Democratic Republic a new separated German state with its political and economic structures modelled on those of the Soviet Union. By now chronically ill, Käte Duncker was no longer politically engaged, and never bothered to sign her communist party membership across to the new Socialist Unity Party ("Sozialistische Einheitspartei Deutschlands" / SED), which, following its creation in April 1946, quickly became the ruling party in a new kind of German one-party dictatorship. Nevertheless, on 2 June 1948 she wrote to her old friend and comrade, Wilhelm Pieck, imploring him to use his personal influence to find out what had happened to her younger son, . Like Wolfgang Duncker, Wilhelm Pieck had moved to Moscow in 1935: unlike Wolfgang, he had survived, and was now a top German politician in the Soviet occupation zone. (In 1949 he became East Germany's first president.) On 10 November 1948 the Dunckers received a message from the Red Cross informing them that their younger son had died in on 20 November 1942. According to a detailed report submitted by his wife to the Central Committee of the exiled German Communist Party in Moscow on 22 September 1939, Wolfgang had been arrested on 21 March 1938 and interrogated. He had been forced, after four months, to sign a false confession, and then taken to a concentration camp where conditions had been grim. (Wolfgang's widow had survived the war, working in a (military) tank factory, and returned to the Soviet occupation zone in 1945 accompanied by her second husband and her two surviving children.)
