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, 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: When was Zimbabwe's new flag first raised? Passage:Following Rhodesia's Unilateral Declaration of Independence from the British Empire, the new Rhodesian authorities started to crack down on African liberation movements. One of their considerations was to ban performance of "Ishe Komborera Africa" in African schools and public performance of it often made people liable for arrest by the British South African Police. The District Commissioner for Gutu abolished the Gutu African Council after its leader opened a meeting by singing "Ishe Komborera Africa" in the District Commissioner's presence. The Commissioner also had the leader arrested but he was released without charge. Following the Southern Rhodesian general election, 1980, after Zimbabwe Rhodesia returned to British control as Southern Rhodesia, Robert Mugabe's Zimbabwe African National Union party won to become the first government of an independent Zimbabwe. After this, "Ishe Komborera Africa" was selected to replace the official "God Save the Queen" of Southern Rhodesia and the unofficial "Rise, O Voices of Rhodesia" of Rhodesia as the national anthem of an independent Zimbabwe as it was a symbol of black African struggles and solidarity against apartheid systems in South Africa and Namibia. At the Zimbabwean independence ceremony, the Union Jack was lowered to "God Save the Queen" and the new flag of Zimbabwe was raised to "Ishe Komborera Africa" in Salisbury.

Input: Consider Input: Question: Which of the institutions that MacIntyre attended in Arizona was founded first? Passage:MacIntyre was born in Redondo Beach, California to Douglas R. and Carole C. (Williams) MacIntyre and has a younger brother, Todd (born 1988) and a younger sister, Katelyn (born 1991). MacIntyre started playing the piano by ear when he was three years old. He was taught by a neighborhood piano teacher near their home in Redondo Beach, California. At six years of age, he began training in classical music. When Scott turned 10, the family moved to Toronto, Ontario, Canada. They lived there for four years, and in that time Scott studied at the Royal Conservatory of Music. The MacIntyre family then relocated to Arizona and Scott studied under Walter Cosand, a university professor of Arizona State University. He was home-schooled until the age of 14, when he was admitted into Arizona State University's Barrett Honors College and Herberger College of the Arts. Scott won the 2004 Arizona Young Artists Competition at Herberger Theater in the vocal division. In 2005, USA Today named him one of its twenty College Academic All-Stars. In 2005, MacIntyre performed as a guest soloist with the Phoenix Symphony. The same year, MacIntyre was diagnosed with kidney disease and in November 2006, he had to spend ten months undergoing dialysis, severely hampering his capacity to perform and travel. In 2007 on August 22, Walter Cosand's wife Patricia donated her kidney to MacIntyre, which saved his life. He graduated from ASU in 2005, and he was received in the White House by Laura Bush as one of the RFB&D (Recording for the Blind and Dyslexic) scholarship winners in 2006. He obtained his master's degree at Royal Holloway, University of London and the Royal College of Music, where he studied on a Marshall Scholarship, one of the most competitive scholarships in the United States, awarded to only 40 American students each year.
