Problem: Background: Hasan ibn Ali ibn Muhammad (c. 846 - 874) was the 11th Imam of Twelver Shia Islam, after his father Ali al-Hadi. He was also called Abu Muhammad and Ibn al-Ridha. Because Samarra, the city where he lived, was a garrison town, he is generally known as al-Askari (Askar is the word for military in Arabic). Al-Askari married Narjis Khatun and was kept under house arrest or in prison for most of his life, until, according to some Shia sources, he was poisoned at the age of 28 on the orders of the Abbasid caliph Al-Mu'tamid and was buried in Samarra.
Context: Various legends relate to al-Askari's wife, Narjis Khatun (the mother of the twelfth Imam, Muhammad al-Mahdi). It is said that al-Askari's father, Ali al-Hadi, wrote a letter in the script of Rum; put it in a red purse, with 220 Dinars; and gave it to his friend Bashar ibn Sulaiman. The letter instructed him to go to Baghdad, to a ferry place on the river where the boats from Syria were unloaded, and female slaves were sold. Bashar was told to look out for a shipowner named Amr ibn Yazid, who had a slave girl who would call out in the language of Rum: "Even if you have wealth and the glory of Solomon the son of David, I can never have affection for you, so take care lest you waste your money." And that if a buyer approached her, she would say "Cursed be the man who unveils my eyebrow!" Her owner would then protest, "But what recourse do I have I; I am compelled to sell you?" "You will then hear the slave answer", said the Imam, "Why this hast, let me choose my purchaser, that my heart may accept him in confidence and gratitude."  Bashar gave the letter, as he was instructed, to the slave girl; who read it, and was not able to keep from crying afterward. Then she said to Amr ibn Yezid, "Sell me to the writer of this letter, for if you refuse I will surely kill myself." "I therefore talked over the price with Amr until we agreed on the 220 Dinars my master had given me," said Bashar. On her way to Samarra, the slave girl would kiss the letter and rub it to her face and body; and when asked by Bashar why she did so despite not knowing the writer of the letter, she said, "May the offspring of the Prophet dispel your doubts!" Later on, however, she gave a full description of the dream she had had, and how she had escaped from her father's palace. A lengthier version of this story is recorded in Donaldson's book, along with further discussion on the authenticity of this story.  Some Shia sources have recorded her as being a "Roman (i.e. Byzantine) princess" who pretended to be a slave so that she might travel from her kingdom to Arabia. Mohammad Ali Amir-Moezzi, in the Encyclopedia of Iranica, suggests that the last version is "undoubtedly legendary and hagiographic".
Question: what did he do with it then?
Answer: and gave it to his friend Bashar ibn Sulaiman. The letter instructed him to go to Baghdad, to a ferry

Problem: Background: Frederick Carlton "Carl" Lewis (born July 1, 1961) is an American former track and field athlete who won nine Olympic gold medals, one Olympic silver medal, and 10 World Championships medals, including eight gold. His career spanned from 1979 to 1996, when he last won an Olympic event. He is one of only three Olympic athletes who won a gold medal in the same individual event in four consecutive Olympic Games. Lewis was a dominant sprinter and long jumper who topped the world rankings in the 100 m, 200 m and long jump events frequently from 1981 to the early 1990s.
Context: The International Association of Athletics Federations (IAAF), the governing body of track and field, organized the first World Championships in 1983. Lewis' chief rival in the long jump was predicted to be the man who last beat him: Larry Myricks. But though Myricks had joined Lewis in surpassing 28 ft 0 in (8.53 m) the year before, he failed to qualify for the American team, and Lewis won at Helsinki with relative ease. His winning leap of 8.55 m (28 ft 0 1/2 in) defeated silver medalist Jason Grimes by 0.26 m (0 ft 10 in).  He also won the 100 m with relative ease. There, Calvin Smith who had earlier that year set a new world record in the 100 m at altitude with a 9.93 s performance, was soundly beaten by Lewis 10.07 s to 10.21 s. Smith won the 200 m title, an event which Lewis had not entered, but even there he was partly in Lewis' shadow as Lewis had set an American record in that event earlier that year. He won the 200 m on June 19 at the TAC/Mobil Championships in 19.75 s, the second-fastest time in history and the low-altitude record, only 0.03 s behind Pietro Mennea's 1979 mark. Observers here noted that Lewis probably could have broken the world record if he did not ease off in the final meters to raise his arms in celebration. Finally, Lewis ran the anchor in the 4 x 100 m relay, winning in 37.86 s, a new world record and the first in Lewis' career.  Lewis' year-best performances in the 100 m and long jump were not at the World Championships, but at other meets. He became the first person to run a sub-10 second 100 m at low-altitude with a 9.97 s clocking at |Modesto on May 14. His gold at the World Championships and his other fast times earned him the number one ranking in the world that year, despite Calvin Smith's world record. At the TAC Championships on June 19, he set a new low-altitude record in the long jump, 8.79 m (28 ft 10 in) and earned the world number one ranking in that event. Track and Field News ranked him number two in the 200 m, despite his low-altitude record of 19.75 s, behind Smith, who had won gold at Helsinki. Lewis was again named Athlete of the Year by the magazine.
