Input: Question: Which Armored Regiment was based in a larger town? Passage 1:In March 1945, the 1st Tank Division with its 5th Armored Regiment was reassigned to the Japanese home islands in preparation for the expected invasion by Allied forces. It gained the IJA 1st Armored Regiment from the 3rd Tank Division, and formed part of the IJA 36th Army under the Japanese Twelfth Area Army. The headquarters unit and IJA 1st Armored Regiment were based in Sano, Tochigi, with the IJA 5th Armored Regiment stationed at Otawara, Tochigi (and later relocated to Kazo, Saitama, and the IJA 1st Mechanized Infantry Regiment and the Division's mechanized artillery stationed at Tochigi. Anticipating that Allied forces would land at Kujukuri Beach, the 1st Tank Division was to hold a defensive line stretching from Mount Tsukuba to the Tama River, with forward units deployed to Choshi, Chiba. The surrender of Japan came before the landing, and the 1st Armored Division did not see any combat on Japanese soil.
Passage 2:Fredell Lack was born in Tulsa, Oklahoma, the oldest of three children of Jewish Eastern European (Latvian) immigrants, Abram I. Lack and Sarah Stillman Lack (who was a sister of noted painter Ary Stillman). She began violin lessons at age six, studying with Tosca Berger. When Fredell was 10, she moved with her family to Houston, Texas. There she studied with Josephine Boudreaux, the concertmaster of the Houston Symphony. At age 11, she first soloed with orchestra, performing the Wieniawski Concerto No. 2 with the Tulsa Philharmonic. At 12, Lack was accepted into the New York City studio of the legendary violinist and pedagogue Louis Persinger, whose other students included such artists as Yehudi Menuhin, Isaac Stern, and Ruggiero Ricci. She moved to New York and completed her pre-college schooling at the Bentley School while continuing her violin lessons with Persinger. At 17, she made her professional solo debut, playing the Mendelssohn Violin Concerto with the St. Louis Symphony. Subsequently she received a full scholarship to the Juilliard School in New York. She continued studying violin with Persinger there and also was deeply influenced by her study of chamber music with Felix Salmond. She received the Diploma from Juilliard at age 21.
Passage 3:When the song was first released as a single in 1994, no remixes were commissioned. Carey re-released the song commercially in Japan in 2000, with a new remix known as the So So Def remix. The remix contains new vocals and is played over a harder, more urban beat that contains a sample of Afrika Bambaataa & the Soulsonic Force's "Planet Rock;" it features guest vocals by Jermaine Dupri and Bow Wow. The remix appears on Carey's compilation album Greatest Hits (2001) as a bonus track. A video was created for the So So Def remix, but it does not feature Carey or the hip-hop musicians that perform in the song. Instead, the video is animated and based on a scene in the video from Carey's "Heartbreaker" (1999). It features cartoon cameo appearances by Carey, Jermaine Dupri, Bow Wow, Luis Miguel (Carey's boyfriend at the time), Carey's dog Jack, and Santa Claus. In 2009 and 2010, the song was included in a music video accompanying ESPN's (and their sister station, ABC) Christmas Day coverage of the NBA.
