Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: What is the current population of the city that both Rodrigo's cousin and father were mayor of? Passage: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.

Example Input: Question: Did Louis XIV's cousin have any siblings? Passage:After Louis XIV's marriage to Maria Theresa of Spain on 9 June 1660, Queen Anne turned her attention to the marriage of Philippe. He had previously been encouraged to court his older cousin the Duchess of Montpensier, eldest daughter of Gaston and his first wife Marie de Bourbon. Known as Mademoiselle at this time, she had an immense private fortune and had previously rejected suitors such as Charles II of England. Born in 1627, she was the sole heiress of her mother who died in childbirth. Mademoiselle declined the union, complaining that Philippe always stayed near his mother as if he was "like a child". Mademoiselle instead remained unmarried. Philippe would marry instead another first cousin, Princess Henrietta of England, youngest child of King Charles I of England and his wife Queen Henrietta Maria, who was Philippe's aunt and had taken refuge at the court of France after the birth of Princess Henrietta in 1644. They lived at the Palais Royal and at the Palais du Louvre. In 1660, after the restoration of the House of Stuart to the throne of England under her brother Charles II, Princess Henrietta returned to England to visit her sister, the Princess of Orange, who later caught smallpox and died. The French court officially asked for Henrietta's hand on behalf of Philippe on 22 November 1660 while she was in England. The couple signed their marriage contract at the Palais Royal on 30 March 1661. The ceremony took place the next day in the same building in front of select members of the court. The dowry promised was a huge 840,000 livres. Known as Henriette d'Angleterre in France, and Minette to her intimates, she was known officially as Madame and was ever popular with the court. Court gossip later said that the king was the father of Henrietta's first child. Henrietta's very open flirting is said to have caused a jealous Philippe to retaliate by beginning to flaunt his sexuality openly in a less than accepting era.

Example Input: Question: What is the average daily load for the Duisburg to Dusseldorf railway line? Passage:The station is situated at the northern end of the relatively straight Duisburg to Düsseldorf railway line which has to cope with one of the highest daily loads in continental Europe. This line is slated to be widened to six tracks in the near future. Currently it has four—and in some places five—tracks. Parallel to it to the east is the local line to Duisburg-Wedau, remnant of a relief line to Düsseldorf which only sees a local shuttle service today but is heavily used by freight trains (which usually do not run through the station but bypass it on a freight-only line two miles to the east). The third line from the south is the railway line to Krefeld and Mönchengladbach. This crosses the River Rhine and then splits into the main line and a branch to Moers and Xanten at Rheinhausen. North of the station, seven tracks run to the River Ruhr crossing (which is a sight on the Route der Industriekultur (Route of industrial heritage) due to a maze of girder bridges) where a three track line split for Oberhausen and on to Antwerp and the other line runs to Dortmund via Gelsenkirchen. The four-tracked main line turns east and runs via Essen and Bochum to Dortmund.
