Question: Which of the people that Sir Simon Fraser fought with during the Scottish Wars of Independence was the oldest? Passage:During the Scottish Wars of Independence, Sir Simon Fraser, known as "the Patriot", fought first with the Red Comyn, and later with Sir William Wallace and Robert the Bruce. Sir Simon is celebrated for having defeated the English at the Battle of Roslin in 1303, with just 8,000 men under his command. At the Battle of Methven in 1306, Sir Simon Fraser led troops along with Bruce, and saved the King's life in three separate instances. Simon was allegedly awarded the 3 Crowns which now appear in the Lovat Arms for these three acts of bravery. He was however captured by the English and executed with great cruelty by Edward I of England in 1306, in the same barbaric fashion as Wallace. At the Battle of Bannockburn in 1314, Sir Simon's cousin, Sir Alexander Fraser of Touchfraser and Cowie, was much more fortunate. He fought at Bannockburn, married Bruce's sister, and became Chamberlain of Scotland. The Frasers of Philorth who are chiefs of the senior Clan Fraser trace their lineage from this Alexander. Alexander's younger brother, another Sir Simon Fraser, was the ancestor of the chiefs of the Clan Fraser of Lovat. This Simon Fraser was killed at the Battle of Halidon Hill in 1333, along with his younger brothers Andrew and James.

Question: Who are the Gestapo? Passage:On 30 June 1943 he was arrested by the Gestapo in Warsaw and sent to Berlin. Rowecki was arrested due to his betrayal by Ludwik Kalkstein "Hanka", Eugeniusz Swierczewski "Genes" and Blanka Kaczorowska "Sroka" who were Gestapo agents. All of them were members of the Home Army but in fact collaborated with the Gestapo. Swierczewski, Kalkstein and Kaczorowska were sentenced to death for high treason by the Secret War Tribunal of the Polish Secret State. The sentence on Eugeniusz Swierczewski was carried out by troops commanded by Stefan Rys ("Jozef"). They hanged Swierczewski in the basement of the house at 74 Krochmalna Street in Warsaw. Kalkstein received protection from the Gestapo and was not harmed. He fought in a Waffen SS unit during the Warsaw Uprising of 1944 under the name of Konrad Stark. After the war, he worked for the Polish Radio station in Szczecin and was later recruited as an agent by the Urzad Bezpieczenstwa. In 1982, he emigrated to France; he died in 1994. Blanka Kaczorowska also survived the war. Her death sentence was not carried out because she was pregnant. After the war, she also worked as a secret agent for the Urzad Bezpieczenstwa and later for the renamed Suzba Bezpieczenstwa. She emigrated to France in 1971. She died in 2002

Question: How many weeks did Jackson's debut single stay on the Billboard Hot Country Singles chart? Passage:The singles discography of Wanda Jackson, an American recording artist, consists of seventy-eight singles, nine international singles, one charting b-side, and three music videos. In 1954 at age sixteen, she signed as a country artist with Decca Records. Her debut single was a duet recording with Billy Gray which reached the eighth spot on the Billboard Hot Country Singles chart, also in 1954. Refusing to tour until completing high school, Jackson's further singles for Decca failed gaining success. She signed with Capitol Records in 1956 and began incorporating rock and roll into her musical style. Jackson's first Capitol single exemplified this format ("I Gotta Know") and became a national top-twenty country hit. Follow-up rock singles between 1957 and 1959 failed gaining enough attention to become hits including, "Hot Dog! That Made Him Mad", "Fujiyama Mama", and "Honey Bop". In 1960 however, the rock and roll-themed, "Let's Have a Party", became Jackson's first Billboard top-forty pop hit after it was picked up by an Iowa disc jockey.
