Question: Question: How many novels are included in Lund's historical fiction series? Passage:Mormon fiction is fiction by or about members of The Church of Jesus Christ of Latter-day Saints, also called Mormons or Latter-day Saints (LDS). Its history is commonly divided into four sections as first organized by Eugene England. During the first fifty years of the church's existence, 18301880, fiction was not popular, though Parley P. Pratt wrote a fictional Dialogue between Joseph Smith and the Devil. With the emergence of the novel and short stories as popular reading material, Orson F. Whitney called on fellow members to write inspirational stories. During the home literature movement, church-published magazines published many didactic stories and Nephi Anderson wrote the novel Added Upon. The generation of writers after the home literature movement produced fiction that was recognized nationally but was seen as rebelling against home literature's outward moralization. Vardis Fisher's Children of God and Maurine Whipple's The Giant Joshua were prominent novels from this time period. In the 1970s and 1980s, authors starting writing realistic fiction as faithful Mormons. Acclaimed examples include Levi S. Peterson's The Backslider and Linda Sillitoe's Sideways to the Sun. Home literature experienced a resurgence in popularity in the 1980s and 1990s when church-owned Deseret Book started to publish more fiction, including Gerald Lund's historical fiction series The Work and the Glory and Jack Weyland's novels.

Question: Question: How many siblings did Khalid have in total? 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.

Question: Question: Why did the Nok culture die off about 200 AD on the Jos Plateau? Passage:The Nok culture thrived from approximately 1,500 BC to about 200 AD on the Jos Plateau in north and central Nigeria and produced life-sized terracotta figures that include human heads, human figures, and animals. Iron smelting furnaces at Taruga, a Nok site, date from around 600 BC. The Nok culture is thought to have begun smelting iron by 600-500 BC and possibly some centuries earlier. Kainji Dam excavations revealed iron-working by the 2nd century BC. Evidence of iron smelting has also been excavated at sites in the Nsukka region of southeast Nigeria in what is now Igboland: dating to 2,000 BC at the site of Lejja (Uzomaka 2009) and to 750 BC and at the site of Opi (Holl 2009). The transition from Neolithic times to the Iron Age apparently was achieved indigenously without intermediate bronze production. Others have suggested that the technology moved west from the Nile Valley, although the Iron Age in the Niger River valley and the forest region appears to predate the introduction of metallurgy in the upper savanna by more than 800 years. The earliest iron technology in West Africa has also been found to be contemporary with or predate that of the Nile valley and North Africa, and some archaeologists believe that iron metallurgy was likely developed independently in sub-Saharan West Africa.
