Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: What is the current population of the city that both Rodrigo's cousin and father were mayor of? Passage 1:Petre was awarded the Military Cross on 14 January 1916, and was mentioned in despatches twice more over the course of the year. In May 1916 he contracted typhoid and was sent to India for recuperation. He transferred out of No. 30 Squadron in December, and was awarded the Distinguished Service Order the same month. In February 1917, he was posted to France with No. 15 Squadron RFC, a reconnaissance unit operating B.E.2s. Two months later his youngest brother John, a squadron commander in the Royal Naval Air Service and a Distinguished Service Cross recipient, was killed in a flying accident. Petre subsequently returned to England and took charge of No. 5 Squadron AFC (also known as No. 29 Squadron RFC), a training unit for Australian fighter pilots, particularly those destined for Palestine. He had hoped to command No. 1 Squadron AFC in Palestine but received an adverse report concerning his leadership abilities, and the position went to Williams. Petre was discharged from the AFC as a major on 31 January 1918, to take a commission with the RFC. In April that year, he transferred to the newly formed Royal Air Force, establishing and commanding No. 75 (Home Defence) Squadron.
 Passage 2:In music, Pearman released her debut studio album at the age of seven, Here's to New Dreams (1993), which saw the moderate commercial success of the single "That's What Little Girls Are Made Of".

Pearman has also lent her voice to the animated series Kim Possible for the character Monique, and films such as Tinker Bell (2008). In 2011, she starred in the lead role on the short-lived ABC Family sitcom State of Georgia. After appearing in recurring roles on Empire and Black-ish, she joined the panel of the ABC daytime talk show The View from 2015 to 2016. Since 2017, Pearman has reprised her role as Raven Baxter on Raven's Home, for which she was nominated for the Daytime Emmy Award for Outstanding Performer in Children's Programming.

 Passage 3:Duterte was born on March 28, 1945, in Maasin. His father was Vicente G. Duterte (1911–1968), a Cebuano lawyer, and his mother, Soledad Duterte (née Roa; 1916–2012), was a school teacher from Cabadbaran, Agusan and a civic leader of Maranao descent. Duterte's father was mayor of Danao, Cebu, and subsequently the provincial governor of (the then-undivided) Davao province. Rodrigo's cousin Ronald was mayor of Cebu City from 1983 to 1986. Ronald's father, Ramon Duterte, also held the position from 1957 to 1959. The Dutertes consider the Cebu-based political families of the Durano and the Almendras clan as relatives. Duterte also has relatives from the Roa clan in Leyte through his mother's side. Duterte's family lived in Maasin, and in his father's hometown in Danao, until he was four years old. The Dutertes initially moved to Mindanao in 1948 but still went back and forth to the Visayas until 1949. They finally settled in the Davao Region in 1950. Vicente worked as a lawyer engaged in private practice. Soledad worked as a teacher until 1952 when Vicente entered politics.
