PROBLEM: Passage: Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.
 Link Information: Blackfish (c. 1729–1779) ( or ), was a Native American leader, war chief of the Chillicothe division of the Shawnee tribe Answer: Shawnee

SOLUTION: Which tribe was Chief Blackfish the Chief of?

PROBLEM: Passage: He was selected as Sepahan's assistant coach in 2006 by Luka Bonačić. After Sepahan was unable to win the 2007–08 season and was ranked as runner up like AFC Champions League and winning Hazfi Cup in both 2006 and 2007, Bonačić was resigned as Sepahan's head coach and was appointed as Dubai based team, Al-Nasr Sports Club. He was selected Ghanbari as his first team assistant coach which was worked with him until his dismissal in February 2009. After he expired his contract with Al-Nasr, he became assistant manager of Sepahan for a second time under management of Amir Ghalenoei. He continue his career with Sepahan after Ghalenoie's resignation in 2011. Bonačić was appointed as Sepahan head coach for a second tensure and Ghanbari was one of his assistants. On 14 August 2011 and after Bonačić was sacked by club due to bad results, Ghanbari became caretaker manager of Sepahan. He was replaced with Zlatko Kranjčar after Sepahan was eliminated from Hazfi Cup. On 30 May 2012, he was named as Mansour Ebrahimzadeh's assistant coach in Naft Tehran. After Ebrahimzadeh signed as head coach of Rah Ahan, Ghanbari also signs a contract to become his assistant.
 Link Information: On 28 May 2012, he signed a one-year contract with Naft Tehran.  Answer: 1

SOLUTION: How long was Ebrahimzadeh coach at Naft Tehran?

PROBLEM: Passage: Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions – identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space – that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Über die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
 Link Information: Issai Schur (January 10, 1875 – January 10, 1941) Answer: 53

SOLUTION:
What was the age of Issai Schur when Bieberbach wrote a book with him?
