Example 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.

Example Input: Question: Did all the artists in the 1892 exhibition paint with the same materials? Passage:The Franco-German art dealer and publisher Siegfried Bing played a key role in publicizing the style. In 1891, he founded a magazine devoted to the art of Japan, which helped publicize Japonism in Europe. In 1892, he organized an exhibit of seven artists, among them Pierre Bonnard, Félix Vallotton, Édouard Vuillard, Toulouse-Lautrec and Eugène Grasset, which included both modern painting and decorative work. This exhibition was shown at the Société nationale des beaux-arts in 1895. In the same year, Bing opened a new gallery at 22 rue de Provence in Paris, the Maison de l'Art Nouveau, devoted to new works in both the fine and decorative arts. The interior and furniture of the gallery were designed by the Belgian architect Henry Van de Velde, one of the pioneers of Art Nouveau architecture. The Maison de l'Art Nouveau showed paintings by Georges Seurat, Paul Signac and Toulouse-Lautrec, glass from Louis Comfort Tiffany and Emile Gallé, jewellery by René Lalique, and posters by Aubrey Beardsley. The works shown there were not at all uniform in style. Bing wrote in 1902, "Art Nouveau, at the time of its creation, did not aspire in any way to have the honor of becoming a generic term. It was simply the name of a house opened as a rallying point for all the young and ardent artists impatient to show the modernity of their tendencies."
