Problem: Background: Robert Stewart, 2nd Marquess of Londonderry,  (18 June 1769 - 12 August 1822), usually known as Lord Castlereagh, which is derived from his courtesy title Viscount Castlereagh, (UK:  KAH-s@l-rey), was an Irish/British statesman. As British Foreign Secretary, from 1812 he was central to the management of the coalition that defeated Napoleon and was the principal British diplomat at the Congress of Vienna. Castlereagh was also leader of the British House of Commons in the Liverpool government from 1812 until his suicide in August 1822. Early in his career, as Chief Secretary for Ireland, he was involved in putting down the Irish Rebellion of 1798 and was instrumental in securing the passage of the Irish Act of Union of 1800.
Context: Stewart had recurring health problems throughout his childhood, and his family elected to send him to The Royal School, Armagh, rather than to England for his secondary education. At the encouragement of Charles Pratt, first Earl of Camden, who took a great interest in him and treated him as a grandson by blood, he later attended St. John's College, Cambridge (1786-87), where he applied himself with greater diligence than expected from an aristocrat and obtained first class in his last examinations. He left Cambridge due to an extended illness, and after returning to Ireland did not pursue further formal education.  In 1790, Stewart was elected as a Member of the Irish Parliament for Down in one of the most expensive elections in Irish history. Though for a time he was associated with the Northern Whig Club, he entered the Irish House of Commons as an Independent. He ran on a platform supporting Whig principles of electoral reform and opposing the Irish policies of the British Government. But even from the outset of his career, he was a personal supporter of the Prime Minister, William Pitt. Stewart was a lifelong advocate of Catholic concessions, though his position on the specific issue of Catholic Emancipation varied depending on his assessment of the potential repercussions on other policy priorities.  When war with France forced British Government attention on Ireland as a possible place of French invasion, the Irish Volunteers, seen as a potential source of disaffection, were disbanded by Dublin Castle, and a reorganised Militia was created in 1793. Stewart enrolled as an officer, a matter of course for a young Protestant aristocrat, and served as Lieutenant Colonel under the command of his wife's uncle, Thomas Conolly. Between Stewart's attendance to his militia duties, his pursuit of cultural, family and political interests in London, two trips to the Continent (in 1791, when he visited revolutionary Paris, and 1792), and the courtship of his wife whom he married in 1794, his life during this period was not centred on the activities of the Irish House of Commons, where he was listened to with respect but where he was not yet an important player. He was also beginning to disappoint some of his more radical original supporters in his constituency. As the French Revolution grew more bloody and Ireland more rebellious, Stewart increasingly worried about Ireland's future if the threats from France succeeded in breaking Ireland's links to Britain. He became further inclined to support not only Pitt personally but the British Government, even when he did not approve of a specific line taken in Irish policy.  In 1794, partly as a result of the promotion of Stewart's interests by his Camden connections, he was offered the Government-controlled seat of Tregony in Cornwall, where he was elected to the British House of Commons on a similar platform of reform principles and support for Pitt, on whose side he sat in Westminster. In 1796, he transferred to a seat for the Suffolk constituency of Orford, which was in the interest of his mother's family, the Seymour-Conways (Marquess of Hertford).
Question: What type of illness did he suffer from?
Answer: He left Cambridge due to an extended illness,

Problem: Background: Britney Jean Spears (born December 2, 1981) is an American singer, dancer, and actress. Born in McComb, Mississippi, and raised in Kentwood, Louisiana, she performed acting roles in stage productions and television shows as a child before signing with Jive Records in 1997. Spears's first and second studio albums, ...Baby One
Context: In February 2001, Spears signed a $7-8 million promotional deal with Pepsi, and released another book co-written with her mother, titled A Mother's Gift. Her self-titled third studio album, Britney, was released in November 2001. While on tour, she felt inspired by hip hop artists such as Jay-Z and The Neptunes and wanted to create a record with a funkier sound. The album debuted at number one in the Billboard 200 and reached top five positions in Australia, the United Kingdom and mainland Europe and sold over 12 million copies worldwide. Stephen Thomas Erlewine of AllMusic called Britney "the record where she strives to deepen her persona, making it more adult while still recognizably Britney. [...] It does sound like the work of a star who has now found and refined her voice, resulting in her best record yet." The album was honored with two Grammy nominations--Best Pop Vocal Album and Best Female Pop Vocal Performance for "Overprotected"-- and was listed in 2008 as one of Entertainment Weekly's "100 Best Albums from the Past 25 Years". The album's first single, "I'm a Slave 4 U", became a top-ten hit worldwide.  Spears's performance of the single at the 2001 MTV Video Music Awards featured a caged tiger and a large albino python draped over her shoulders. It was harshly received by animal rights organization PETA, who claimed the animals were mistreated and scrapped plans for an anti-fur billboard that was to feature Spears. To support the album, Spears embarked on the Dream Within a Dream Tour. The show was critically praised for its technical innovations, the piece de resistance being a water screen that pumped two tons of water into the stage. The tour grossed $43.7 million, becoming the second highest grossing tour of 2002 by a female artist, behind Cher's Farewell Tour. Her career success was highlighted by Forbes in 2002, as Spears was ranked the world's most powerful celebrity. Spears also landed her first starring role in Crossroads, released in February 2002. Although the film was largely panned, critics praised Spears's acting and the film was a box office success. Crossroads, which had a $12 million budget, went on to gross over $61.1 million worldwide.  In June 2002, Spears opened her first restaurant, Nyla, in New York City, but terminated her relationship in November, citing mismanagement and "management's failure to keep her fully apprised". In July 2002, Spears announced she would take a six-month break from her career; however, she went back into the studio in November to record her new album. Spears's relationship with Justin Timberlake ended after three years. In December 2002, Timberlake released the song "Cry Me a River" as the second single from his solo debut album. The music video featured a Spears look-alike and fueled the rumors that she had been unfaithful to him. As a response, Spears wrote the ballad "Everytime" with her backing vocalist and friend Annet Artani. The same year, Limp Bizkit frontman Fred Durst said that he was in a relationship with Spears. However, Spears denied Durst's claims. In a 2009 interview, he explained that "I just guess at the time it was taboo for a guy like me to be associated with a gal like her."
