Input: Consider Input: Question: How long after the 1st Tanks Division was reassigned did the surrender of Japan occur? Passage: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 Ōtawara, 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 Kujūkuri 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.

Input: Consider Input: Question: What year was the person who Chantal met in the summer of 2003 born? Passage:Canadian singer-songwriter, producer and pianist Chantal Kreviazuk has written, produced and performed on albums and tracks for a wide range recording artists, spanning from adult contemporary, pop, rock, to indie and hip-hop music. Initially, she began writing her own pop songs, especially after a 1994 motorcycle accident in Italy left her immobile for several months, and was signed by Sony Canada, where she released her debut album in June 1997. Chantal later released another album in 1999, before being featured in a range of soundtracks to films and TV series. Chantal began writing for other artists in 2001, where she co-wrote the song "Always and Forever" for Eleanor McCain. However, it was only in 2004 that Chantal started writing for more artists and received recognition as a songwriter. In the summer of 2003, Chantal met Canadian singer-songwriter Avril Lavigne, they formed a relationship of mutual respect and sisterhood, and eventually became songwriting partners. They co-wrote six songs for Lavigne's sophomore album, Under My Skin (2004): "Slipped Away," "Forgotten," "Together," "How Does It Feel," "He Wasn't" and "Who Knows." Kreviazuk described "He Wasn't" as "a super-fun, punk, screw-you-to-boys song," while "Forgotten" is a driving rock song inspired by similarly vibed music Lavigne was consumed with at the time. Also in 2004, Chantal co-wrote "Rich Girl", for Gwen Stefani's solo debut album, "Love. Angel. Music. Baby.", along with Dr. Dre, Jerry Bock, Mark Batson, Kara DioGuardi, Mike Elizondo, Sheldon Harnick and Eve. The song became a chart success, reaching the top-ten in over fifteen countries. Chantal also wrote for Kelly Clarkson's breakthrough album "Breakaway" in the end of 2004, sharing writing credits for the tracks "Where is Your Heart" and "Walk Away". In 2005, Chantal's co-writing song "He Wasn't" was released as Lavigne's final single from "Under My Skin", receiving a moderate impact on the charts and reaching only the top-forty in some countries. While in 2006, Clarkson's "Walk Away" was released as "Breakaway"'s final single, reaching the top-twenty in some countries.
