Question: How many years apart in age were Sweyn's sons? Passage 1:Gorm's son, Harald Bluetooth succeeded his father as king and married possibly three times with Gunhild, Tove and Gyrid. Harald had a son named Sweyn Forkbeard. Sweyn succeeded his father as king and married Gunhild (Świętosława of Poland). They had a son named Cnut the Great. Sweyn also ruled England in his lifetime and established the Danish Empire. When Sweyn died, his elder son Harald Svendsen became the King of Denmark, while England's former king, Ethelred, reclaimed the throne. Following Harald's death, his brother Cnut the Great became king, re-established the Danish North Sea Empire. He married Emma of Normandy with whom he had a son named Harthacnut. When Cnut died (and after the brothers of Harthacnut also had died), Harthacnut became king of Denmark and England. Upon his death, Edward the Confessor became ruler of England in 1042. Sweyn Forkbeard also had a daughter, Estrid, from whom all ruling kings and queens of Denmark after 1047 descend.
 Passage 2:Mahaffey set a club record with 17 strikeouts in a game against the Chicago Cubs on April 23, 1961. Though he ended the season with an ERA of 4.10, and a record of 11–19 (leading the NL in losses), in 36 games, he was selected to represent the Phillies on the NL All-Star team. Mahaffey ended the season with a record of 19–14, and a 3.94 ERA, with a career high 177 strikeouts, in 41 games. He was selected again in 1962 for the NL All-Star team, finishing 26th in balloting for NL Most Valuable Player (MVP), despite leading the league in home runs allowed with 36, and earned runs allowed with 120. Mahaffey had a 7–10 record in 26 games with the Phillies, to go along with a 3.99 ERA. In , he finished the season with a record of 12–9, with an ERA of 4.52, in 34 games. The ill-fated 1964 team was in first place in the NL, with a 6-game lead, with just 12 games remaining in the season, before starting a 10-game losing streak that cost the team the pennant. Mahaffey pitched in two of the games in that infamous skid, losing a 1–0 game (the first of that losing streak) on a steal of home by Chico Ruiz of the Cincinnati Reds, and was taken out while winning 4-3 in a game against the Milwaukee Braves, in which Rico Carty hit a ninth-inning bases-loaded triple, plating all 3 runners, off of reliever Bobby Shantz, to win the game for the Braves, 6-4. was his last season in Philadelphia, which saw him finish with a 2–5 record, and an ERA of 6.21, in 22 games, mostly in relief.
 Passage 3:In 1795 Fijnje returned to the Netherlands (after the Batavian Revolution), after which he became a member of the commité van waakzaamheid (the Batavian version of the French Committee of Public Safety), chaired the Provisional Representatives of the People of Holland for a while. and - together with Samuel Iperusz Wiselius and professor Theodorus van Kooten - served on the committee for the liquidation of the VOC. In all these posts he took radical viewpoints, but he also enjoyed himself thoroughly. On 22 January 1798, he performed a Coup d'état with general Herman Willem Daendels, Pieter Vreede and Van Langen to guarantee "the unity and indivisibility" of the Batavian republic. The radical and omnipresent Fijnje represented the Uitvoerend Bewind and founded the "Binnenlandse Bataafse Courant" (Interior Batavian Courier). The controversial unitarissen did not long remain in power, for on 12 June 1798 general Daendels led another coup, this time putting the "moderates" in power in the Uitvoerend Bewind. For the corrupt former exiles with explicit opinions, whether democrat or aristocrat, there was no longer any place. Fijnje and Van Langen were locked up until the end of the year in the Gevangenpoort, accused of embezzling state money by the public prosecutor Van Maanen, but never put on trial.
