Question: Did the chief who predicted the massacre of Mormon towns survive the Black Hawk War? Passage:The Navajo War was not directly a part of the Black Hawk War, but it may have been a source of some of the native warriors who fought in the Black Hawk War. Black Hawk's success drew fighters from other Utes in Colorado, Apaches from New Mexico, and many Navajos. In the winter of 1866 Black Hawk and his band went to the Four Corners region where he received many new recruits. So many Navajos joined him that they formed almost half his raiders. The Navajo had been decimated by the U.S. Army under Kit Carson and forced out of their ancestral homeland. The remaining Navajos were eager for a chance to build up their herds at the expense of white settlers. Manuelito, the most important chief refusing to relocate to the Bosque Redondo Reservation, jointly led Black Hawk's raids on Mormon settlements in southern Utah during 1866. The attacks commenced at Pipe Springs, then a Mormon settlement on the Arizona-Utah border. The retaliation for the Pipe Springs raid left four unarmed Paiutes dead for murders they had nothing to do with. This brought some Paiute fighters to Black Hawk's band. Hopis hearing of the Navajo's movements feared they were to be attacked and struck first ambushing Manuelito's Navajos. The raids continued at the Paria settlements, and Kanab, who sent pleas for help against the raids. In subsequent years, the raids continued in the south by Navajos and Paiutes, which raised tensions to a fever pitch which would result in the worst massacre of the war at Circleville. Chief Kanosh predicted that in 1867 six thousand Navajos would wipe out the Mormon towns in southern Utah.

Question: Who created the character with whom the goddess Bast made her first appearance in Fantastic Four #52? Passage:Characters based on ancient Egyptian deities were first mentioned in Captain America Comics #20 (November 1942), published by Marvel Comics' predecessor Timely Comics, in which Captain America and Bucky investigate the murder of Colonel Fitzpatrick, who was studying the Book of Thoth while stationed in Egypt. The Heliopolitans first full Golden Age appearance was in the story "The Terror That Creeps" by Stan Lee and Werner Roth, published in Marvel Tales #96 (June 1950), and involves a man that fails to convince the public that the Great Sphinx of Giza is slowly moving to the edge of the desert, where it will be empowered by Set and destroy mankind. The goddess Bast would later make her first appearance (as a totem) with the Black Panther in Fantastic Four #52 (July 1966). Many of the other deities, including Horus, Isis and Osiris, were introduced in Thor #239 (September 1975). Khonshu, who became associated with Moon Knight, first appeared in Moon Knight #1 (November 1980). Joseph Muszynski argued in his book Everything I Needed to Know About Life I Learned from Marvel Comics that the introduction of Egyptian deities "excited our tendency to enjoy variety" as the pantheon contained multiple gods and personalities as opposed to the Judeo-Christian religions. Ed Strauss contended that Marvel was able to dive into ancient Egyptian religion because it "had long been retired into the realm of mythology" unlike Christianity.

This was Khan's third film for Sagar Movietone after Al Hilal (1935) and Deccan Queen (1936). The cinematographer was Faredoon Irani who, starting from Mehboob Khan's Al Hilal (Judjement of Allah) (1935) went on to establish a long working relationship with him lasting till Khan's last film Son of India (1962). The music was composed by Ashok Ghosh assisted by Anil Biswas. The story writer was Zia Sarhadi who also wrote the lyrics, screenplay and dialogue in addition to acting in the film. Though he had started his writing career on Khan's backing for Deccan Queen (1936), it was with Manmohan that he achieved success. The film was inspired by Devdas, (1935), which was a big hit at the box office. Surendra was chosen as the singing star to rival K. L. Saigal from New Theatres Calcutta, whose songs from Devdas had mesmerised the nation. Though Manmohan was referred to as the "poor man's Devdas" it went on to do well and the songs became very popular. The film starred Bibbo, Surendra, Yakub, Kayam Ali, Bhudo Advani and Mehdi Raza.
