Input: Consider Input: Question: Which state is Albert P. Laning a Senator for? Passage:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.

Input: Consider Input: Question: Who was the author of the Genji Monogatari Emaki? Passage:Mandalas became predominant in the paintings of the early Heian period as esoteric Buddhism emerged with the Shingon and Tendai sects in the 8th and 9th centuries. The evolution of Pure Land Buddhism caused raigō-zu to be developed as a genre, characterised by depictions of the Amida welcoming the souls of the faithful to his Western Paradise as seen in a 1053 painting in the Phoenix-Hall of Byōdō-in. By the mid-Heian period, Chinese style kara-e painting was replaced with the classical Japanese yamato-e style, in which the images were painted primarily on sliding screens and byōbu folding screens. At the close of the Heian period around 1185, the practice of adorning emakimono hand scrolls with yamato-e paintings flourished. Examples of illustrated hand scrolls include novels such as Genji Monogatari Emaki, historical writings like The Tale of Great Minister Ban, or religious works such as the Scroll of Hungry Ghosts. These genres continued to be produced into the Kamakura period from 1185 to 1333. As during the Nara period, sculpture remained the preferred art form of the period.
