[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.

[Q]: Question: Was the party that Dayan joined more right-wing than his previous party? Passage:Moshe Dayan (; 20 May 1915 16 October 1981) was an Ottoman-born Israeli military leader and politician. He was the second child born on the first kibbutz, but he moved with his family in 1921, and he grew up on a moshav (farming cooperative). As commander of the Jerusalem front in the 1948 ArabIsraeli War, chief of staff of the Israel Defense Forces (195358) during the 1956 Suez Crisis, but mainly as Defense Minister during the Six-Day War in 1967, he became to the world a fighting symbol of the new state of Israel. In the 1930s, he was trained by Orde Wingate to set traps for Palestinian-Arabs fighting the British and he later lost an eye in a raid on Vichy forces in Lebanon. Dayan was close to David Ben-Gurion and joined him in leaving the Mapai party and setting up the Rafi party in 1965 with Shimon Peres. Dayan became Defence Minister just before the 1967 Six-Day War. After the October War of 1973, Dayan was blamed for the lack of preparedness; after some time he resigned. In 1977, following the election of Menachem Begin as Prime Minister, Dayan was expelled from the Labor Party because he joined the Likud-led government as Foreign Minister, playing an important part in negotiating the peace treaty between Egypt and Israel.
