[EX Q]: Question: Which of the Sotto brothers who became senators is the eldest? Passage:Political families started becoming more apparent in the national political scene after World War II and gradually turned into hereditary politics, especially in the provinces. In 1946, Vicente Sotto became a senator after his brother Filemon Sotto previously held a position in the Senate before the war. The 60s saw more frequent instances of relatives getting elected in the Senate such as the election of the brother of then President Ramon Magsaysay; of Magnolia Antonino as Senator after her husband Senator Gaudencio died; of Sergio Osmena Jr. who was the son of 4th President Sergio Osmena Sr.; of Gerardo Roxas who was another son of a previous president; and of Benigno Aquino Jr. who was the son of Benigno Sr.. During the martial law years, it only became worse as Marcos named his wife Imelda as the governor of Metro Manila while his son Bongbong became the governor of Ilocos Norte.

[EX Q]: Question: Who did Manuel's uncle run against for the mayorship of Ciales? Passage:Natal was born into a family with strong ties to the local politics. His maternal uncle, Javier Albelo Matos, served as a candidate for the mayorship of Ciales the 2000 general election, while his paternal grandfather was an activist for the Partido Popular Democratico (PPD). He studied at Colegio Espiritu Santo in Hato Rey, where he was president of the Student Council. Natal obtained a bachelor's degree from Cornell University in 2008, where he was president of the Puerto Rican Student Association. He did not expect to be accepted by the institution, having applied to study in it as a protocolary measure. When the acceptance letter was received, Natal was surprised and this event triggered a period of adaptation. He offered a speech at his graduation in his role of class president. After returning to Puerto Rico, Natal received a juris doctor from the University of Puerto Rico School of Law in 2011, also serving as president of the student council during his tenure. After graduating from Cornell, Natal became a key figure in a series of strikes held at the University of Puerto Rico in protest of a quota being introduced to the students. Consequently he became involved with the Popular Democratic Party and participated in an internal election for the presidency of the party's National Youth organization. After completing his juris doctor Natal opened his own lawfirm and worked for Charlie Hernandez and Luis Vega Ramos, prominent members of the free association movement. In 2013, Natal was named director of the House of Representatives of Puerto Rico Commission on the Judiciary.
