Definition: 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.
Input: Question: How many total recipients of the Grand Cross of the Order of the Dannebrog were there at the time Kjeld Hillingsø was awarded his? Passage 1:Ward Thomas joined RAF Bomber Command in 1941 and trained as a navigator and pilot in South Africa. He joined 100 Squadron as a Lancaster pilot and was later moved to 550 Squadron stationed in Grimsby. He flew 36 trips over France and Germany over the course of the war, including taking part in the Nuremberg raid of March 1944 during which Bomber Command suffered its heaviest loses. He was awarded the Croix de Guerre for his involvement in bombing raids on the German Panzer training camp at Mailly-le-Camp in advance of the Normandy landings in June 1944. He also received the DFC "for utmost fortitude, courage and devotion to duty in air operations" during the War. By the time he left the RAF Ward Thomas had achieved the rank of flight lieutenant.
 Passage 2:Hillingsø was made a sergeant in the Royal Danish Navy in 1955, but changed to serve in the Royal Danish Army, in which he became a Lieutenant of the Danish Royal Life Guards in 1959. In 1986 he was made a colonel and became the chief of the Planning and Operations Staff in the Defence Command. In 1990, he became a Major General, and Chief of the Army. In 1991, he was made head of the newly-created Army Operational Command. In 1993 he became Lieutenant General and head of NATO's BALTAP command, and was also head of the Defence Operational Forces. He held this position until his retirement in 1995, when he was awarded the Grand Cross of the Order of the Dannebrog.
 Passage 3:The fruit bodies of A. abrupta grow on the ground, typically solitary, in mixed conifer and deciduous forests, usually during autumn. The frequency with which fruit bodies appear depends on several factors, such as season, location, temperature, and rainfall. The mushroom has been described as common in the Southeastern United States; in Texas, it has been called both infrequent, and common in the Big Thicket National Preserve. Like most other Amanita species, A. abrupta is thought to form mycorrhizal relationships with trees. This is a mutually beneficial relationship where the hyphae of the fungus grow around the roots of trees, enabling the fungus to receive moisture, protection and nutritive byproducts of the tree, and affording the tree greater access to soil nutrients. Amanita abrupta is widely distributed throughout eastern North America, where it has been found as far north as Quebec, Canada, and as far south as Mexico. Orson K. Miller claims to have found it in the Dominican Republic where it appeared to be growing in a mycorrizhal association with pine trees. Kuo also mentions a mycorrhizal relationship with both hardwoods and conifers, while Tulloss lists additional preferred tree hosts such as beech, birch, fir, tsuga, oak, and poplar. However, A. abrupta has been shown experimentally to not form mycorrhizae with Virginia Pine.
