Problem:Question: What was the reason for the event Alfred was expelled for participating in? Passage 1:On 1 September 2012, Affane made his debut for the club against Willem II where he came on as a substitute in the second half and provided the assist for Krisztián Németh's goal and also won the Man of the match. Roda JC went on to win the match 3–0 and this was their first league win in the 2012–13 season. He started his first game for Roda in their next fixture on 16 September 2012 away to AZ Alkmaar, where the game ended in a 4–0 loss. On 25 September 2012, Affane made his KNVB Cup debut for Roda, where they lost 1–0 at home to PEC Zwolle in the extra time. On 30 September 2012, he scored his first goal for Roda in an Eredivisie match where they lost 3–2 to Groningen. He came in as a substitute in the 71st minute and awarded the team with a hard shot from 22 meters and scored the equalizer from a pass by Abel Tamata, 2–2 in the 78th minute. On 20 October 2012, Amin again came in to play as a substitute in the second half of the match where they were drawn 1–1 to FC Twente and assisted the only goal by them, which was scored by Guus Hupperts, while Affane's low cross was missed by Twente goalkeeper Nikolay Mihaylov. On 11 November 2012, Affane set up their two goals which were scored by Senharib Malki and Bart Biemans, both from corners in a 5–2 away loss against Feyenoord at De Kuip. Amin Affane returned to Chelsea after seeing the loan spell at Eredivisie side Roda JC cut short. He initially saw plenty of first-team football at Roda, but fell out of favour in February and has subsequently been deemed surplus to requirements.
 Passage 2:Alfred Stillé (October 30, 1813 – September 24, 1900) was an American physician. Born in Philadelphia, he studied classics at Yale, but was expelled for participating in the Conic Sections Rebellion. He then transferred to the University of Pennsylvania in the same year, where he received an A.B. degree in 1832. He went on to get an A.M. from the University of Pennsylvania in 1835 and in 1836 an M.D. from the school's department of medicine. He settled to practice in his native city, but spent parts of 1841 and 1851 in Paris and Vienna. From 1854 to 1859 he was professor of medicine at the Pennsylvania Medical College and from 1864 to 1884 at the University of Pennsylvania, later becoming its Chair. Stillé was one of the first in America to distinguish between typhus and typhoid fever. His observations in this connection he made during a typhus epidemic in Philadelphia in 1836 and reported in 1838. He acquired a great reputation as a practitioner, teacher, and writer, and was the first secretary, and in 1871–72 the president, of the American Medical Association. However, as evidenced by his later writings, he was also known for refusing to accept the germ theory or laboratory medicine.
 Passage 3:Eritrea returned to the 2009 CECAFA Cup in Nairobi. A young squad was assembled with just 12 days' training. In Group B, they gained a surprise draw with Zimbabwe, lost narrowly to Rwanda, and beat Somalia 3–1. They were easily beaten 4–0 in the quarter-finals by Tanzania. Twelve squad members failed to report for the return flight, and sought the assistance of the Refugee Consortium of Kenya. They were believed to be in hiding in Eastleigh, an eastern suburb of Nairobi home to many immigrants. Nicholas Musonye, the secretary-general of CECAFA, feared that the government might react by refusing to let the team travel abroad in future. The twelve players were later granted interim asylum by the United Nations High Commissioner for Refugees in Kenya. Eleven of these players have since travelled to Adelaide in Australia with two of them, Samuel Ghebrehiwet and Ambes Sium, signing for Gold Coast United in the A-League in August 2011.
