Input: Consider Input: Question: Which of the construction materials that St Nicholas was constructed with has a higher value on the Mohs scale? Passage:St Nicholas is constructed in flint, with some conglomerate and brick, and has limestone dressings. The roofs are tiled. Its plan consists of a nave, a chancel with a north vestry (previously a porch), and a west tower. The tower is wholly octagonal. In each face of the upper stage of the tower is a lancet, and there is another lancet on the west side at a lower level. The parapet is battlemented. The tower has a west doorway in Norman style, which has possibly been re-set from elsewhere in the church. It has scalloped capitals, and zig-zag decoration on the arch. Inside the upper part of the tower is a 17th-century dovecote lined with brick nesting boxes. On the south side, between the tower and the nave, is a brick stair turret. The nave windows have two lights with Decorated tracery. Between the windows on the south side is another Norman doorway, again with zig-zag decoration. The north and south walls of the chancel have two-light windows with Y-tracery, and three-light windows with Perpendicular tracery. The east window has five lights. The east gable is decorated with grotesque carvings, and above the east window is head-corbel and a blocked niche. The vestry has two-light north and south windows. In the north wall of the nave is an Early English doorway, with dog-tooth ornament. Around the church are stepped buttresses.

Input: Consider Input: Question: What is the current capital of the Asian country that Cretin thought about traveling to as a missionary? Passage:He was born in Montluel, in the departement of Ain, France, 19 December 1799. He lived at St. Paul, Minnesota, 22 February 1857. He made his preparatory studies in the Petits seminaires of Meximieux (Ain) and Saint-Genis-l'Argentiere (Rhone), his studies of philosophy at Alix (Rhone), and of theology in the seminary of Saint-Sulpice, Paris. He was ordained priest 20 December 1823, and soon was appointed vicar in the parish at Ferney, once the home of Voltaire, and eventually became its parish priest. He built there a new church and founded a boys' college with funds gathered on a tour through France. At this period, he revived the Catholic faith among many indifferent parishioners, who were made indifferent by the surviving influence of Descartes, and the proximity of the Protestant cantons of Switzerland. But Cretin longed for a larger field of activity; at one time he thought earnestly of going as a missionary to China. His perplexities in that regard were solved by the advent of Bishop Mathias Loras, first bishop of Dubuque, Iowa, who arrived in France in 1838 in search of priests for to evangelize his vast diocese. Cretin was one of the few who volunteered and on 16 August 1838, he secretly left his parish, embarked at Le Havre with Bishop Loras, and landed in New York in October of the same year. The winter of 1838-39 was spent in St. Louis, Missouri, and on his arrival in Dubuque, 18 April 1839, he was immediately appointed vicar-general of the new diocese. For over eleven years, he exercised his priestly ministry in these new regions, dividing his time between Dubuque, Prairie du Chien, Wisconsin, and the Winnebago Indians in the neighborhood of Fort Atkinson, in Winneshiek County, Iowa. Only once, in 1847, did he absent himself, when he made a trip to Europe in the interest of his missions. In 1850 St. Paul, Minnesota became the seat of a new diocese. Cretin was appointed its first bishop, and went to France, to be consecrated, 26 January 1851, at Belley by Bishop Devie, who had ordained him to the priesthood.

Input: Consider Input: Question: Which Whig Party candidate that Gibson supported during U.S. presidential election died first? Passage:Gibson became involved in politics as a member of the Whig Party with strong anti-slavery views. During the U.S. Presidential campaign of 1844, he gave stump speeches for Henry Clay due to the Whig Party's platform that opposed admitting Texas into the Union because it was a slave state. In the U.S. Presidential campaign of 1848, Gibson supported Whig candidate, "Rough and Ready" General Zachary Taylor. However, he was concerned about the Whig Party's lack of opposition to the abolition of slavery and personally visited Henry Clay at his home in Ashland, Kentucky in 1848 to discuss this issue. He lost as a Whig candidate for Ohio Attorney General in 1853. In 1853, following the large defeat of the Whig candidate General Winfield Scott in the U.S. Presidential election of 1852, Gibson threw his support to the Free Soil Party and began organizing what would become the Republican Party in Ohio. He attended the first organization meeting of the Republican Party in spring of 1856 in Pittsburgh. He was one of the 69 Ohio delegates (of a total 600 delegates from around the country) that attended the first Republican National Convention held in Philadelphia in June 1856. In 1856, he ran and was elected as the first Republican to hold the office of Ohio State Treasurer.
