Problem: Background: Jason Leonard (born 14 August 1968) is an English former rugby union player, and has been the president of the Rugby Football Union since 2015. Nicknamed The Fun Bus, Leonard was a prop forward who won 114 caps for England and five for the British and Irish Lions. His total of 119 was a world record until 2006, when it was surpassed by George Gregan. Leonard played in England teams which won four Grand Slams (1991, 1992, 1995 and 2003) and the 2003 Rugby World Cup, and was part of the British and Irish Lions squad that won the test series during their 1997 tour of South Africa.
Context: With Dick Best no longer England head coach, the RFU appointed well-known and highly successful Bath coach Jack Rowell as his replacement. There was much speculation amongst many established England players as to what changes the new coach would bring to the England setup, particularly one with such close ties to a successful Bath Rugby Club. Rowell claimed he would rid England of the cautious, forward-dominated 10-man game which had done so well for them earlier in the decade, and play running rugby more similar to Bath's. Leonard kept his place in the England team, which now included several new players such as Mike Catt, Ben Clarke, Victor Ubogu, Steve Ojomoh (all Bath players) and Tim Rodber. In the 1995 Five Nations, Leonard won a record (for a prop) 38th cap for England, playing against Scotland, and the victory meant his third Grand Slam. England held high hopes for the upcoming Rugby World Cup in South Africa. At the World Cup, England were drawn in Pool B, generally regarded as one of the easier groups in the competition. However, England experienced setbacks, gaining only narrow victories over Argentina (24-18) and Italy (27-20). In England's final pool match against Western Samoa, Leonard was rested and his record of 40 consecutive England caps ended. England won that match 44-22 and also won the subsequent quarter-final against Australia 25-22, before losing the semi-final to New Zealand 29-45 and finishing the tournament in fourth place. In November 1996, Leonard skippered England for the first time, against Argentina at Twickenham. The game was very close, with Argentina taking a narrow lead close to full-time. From a rolling maul, Leonard scored a try to level the scores, and a Mike Catt penalty won the game 20-18. The try remains Leonard's only score for England. In the 1996-1997 season, Leonard began to play for England at tighthead prop (number 3) to make room for Leicester Tigers loosehead prop (number 1), Graham Rowntree, and in 1997, Leonard was selected for his second British and Irish Lions tour, this time to South Africa. In September 1997, the RFU appointed Clive Woodward as head coach. The Autumn internationals saw England playing Australia, South Africa and New Zealand. Against Australia, Leonard found himself selected at loosehead prop again, with Wasps' Will Green winning his first cap at tighthead. For the remaining two tests, Leonard was moved back to tighthead. The ability to scrummage effectively on either side of the scrum proved to be one of Leonard's great assets.
Question: Did he do well there?
Answer: Leonard was selected for his second British and Irish Lions tour, this time to South Africa.

Problem: Background: Umar was born in Mecca to the Banu Adi clan, which was responsible for arbitration among the tribes. His father was Khattab ibn Nufayl and his mother was Hantama bint Hisham, from the tribe of Banu Makhzum. In his youth he used to tend to his father's camels in the plains near Mecca. His merchant father was famed for his intelligence among his tribe.
Context: Umar attended the event of Ghadir Khumm, which took place a few months before Muhammad passed away. According to both Shia and Sunni sources, he was among the many who pledged allegiance to Ali at the event. In Medina, after the Farewell Pilgrimage and the event of Ghadir Khumm, Muhammad ordered an army under the command of Usama bin Zayd. He commanded all the companions, except for his family, to go with Usama to Syria to avenge the Muslims' defeat at the Battle of Mu'tah. Muhammad gave Usama the banner of Islam on the 18th day of the Islamic month of Safar in the year 11 A.H. Abu Bakr and Umar were among those that Muhammad commanded to join Usama's army. However, Abu Bakr and Umar resisted going under the command of Usama because they thought that he, who was 18 or 20 at the time, was too young to lead an army, despite Muhammad's teachings that age and standing in society did not necessarily correspond to being a good general. In response to these worries, the Prophet said: "O Arabs! You are miserable because I have appointed Usama as your general, and you are raising questions if he is qualified to lead you in war. I know you are the same people who had raised the same question about his father. By God, Usama is qualified to be your general just as his father was qualified to be a general. Now obey his orders and go." Whenever Muhammad felt any relief from his fatal sickness, he would inquire as to whether Usama's army had left for Syria yet, and would continue urging his companions to leave for Syria. Muhammad even said, "Usama's army must leave at once. May Allah curse those men who do not go with him." However, while a few companions were ready to join Usama's army, many other companions, including Abu Bakr and Umar, disobeyed Muhammad's orders. It is also noted that this was the only battle expedition where Muhammad urged his companions to go the battle no matter what; for other battles, if someone was unable to go to the fight, Muhammad would let them stay at home.
Question: What was he too young to do?
Answer:
to lead an army,
