Input: Consider Input: Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

Input: Consider Input: 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, 1830–1880, 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.

Input: Consider Input: Question: When was the person born who gave Jon Gruden his nickname? Passage:Under Gruden, the Raiders posted consecutive 8–8 seasons in 1998 and 1999, and leapt out of last place in the AFC West. After uniting with journeyman quarterback Rich Gannon, Gruden led the Raiders to the top of the AFC West and they made the playoffs in three consecutive seasons from 2000 to 2002 (the third season was under head coach Bill Callahan). Oakland finished 12–4 in the 2000 season, the team's most successful season in a decade, and its first division title since 1990, ultimately reaching the , where they lost, 16–3, to the eventual Super Bowl champions Baltimore Ravens. In 2001, the Raiders would return to the postseason with a 10–6 record, but in the AFC Divisional Round a negated fumble proved costly as they were defeated, 16–13, in overtime by the eventual Super Bowl champions New England Patriots. While Gruden was with the Raiders, Gruden acquired his nickname "Chucky" from Raiders defensive lineman Grady Jackson, who thought that the coach looked like the fictional character "Chucky" in the 1988 slasher movie Child's Play.
