PROBLEM: Question: Who was the head of the government that recalled Khalid in 841? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828832, briefly in 841 and again under Caliph al-Wathiq (r. 842845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

SOLUTION: As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately

PROBLEM: Question: Who were the members of the soul music grup Parliament? Passage:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.

SOLUTION:
Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience
