Problem: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 14January 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 31January 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 3:Duterte was born on March 28, 1945, in Maasin. His father was Vicente G. Duterte (19111968), a Cebuano lawyer, and his mother, Soledad Duterte (nee Roa; 19162012), 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.
