Question: Question: When was the Empire that dominated the People of Totanac ethnicity formed? Passage:Totonacapan refers to the historical extension where the Totonac people of Mexico dominated, as well as to a region in the modern states of Veracruz and Puebla. The historical territory was much larger than the currently named region, extending from the Cazones River in the north to the Papaloapan River in the south and then west from the Gulf of Mexico into what is now the Sierra Norte de Puebla region and into parts of Hidalgo. When the Spanish arrived, the Totonac ethnicity dominated this large region, although they themselves were dominated by the Aztec Empire. For this reason, they allied with Hernán Cortés against Tenochtitlán. However, over the colonial period, the Totonac population and territory shrank, especially after 1750 when mestizos began infiltrating Totonacapan, taking political and economic power. This continued into the 19th and 20th centuries, prompting the division of most of historical Totonacpan between the states of Puebla and Veracruz. Today, the term refers only to a region in the north of Veracruz were Totonac culture is still important. This region is home to the El Tajín and Cempoala archeological sites as well as Papantla, which is noted for its performance of the Danza de los Voladores.

Question: 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.

Question: Question: What army did the USS Gunston Hall engage with during the assault on Kwajalein?  Passage:After intensive shakedown along the California coast Gunston Hall prepared to sail for the Western Pacific, where she was to participate in every major operation from February 1944 to the end of the war, 18 months later. Loading 225 men from the 4th Marine Tank Battalion and 2 amphibious units, as well as 15 LVTs, 15 tanks, 17 LCMs, and 15,000 gallons of gasoline, Gunston Hall departed San Diego on 13 January 1944. On D-Day for the assault on Kwajalein, 1 February 1944, she stood offshore to unload her cargo as the Marines stormed the beaches on Roi and Namur Islands. Gunston Hall remained in the area to repair small craft until 6 February, when she reembarked her former passengers and equipment and sailed to Guadalcanal via Funa Futi. The pattern she set here held for her participation in eight further key invasion efforts in the Pacific as the Navy "Island-hopped" marines and Army troops ever closer to the Japanese home islands.
