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: Which of the two politicians that announced the Senate and Assembly committee investigating the Fort Lee lane closure scandal would merge into the bi-partisan joint New Jersey Legislative Select Committee on Investigation had the longest carreer? Passage:On January 21, 2014, Assemblyman John S. Wisniewski and State Senate majority leader Loretta Weinberg, whose district includes Fort Lee, announced that the Senate and Assembly committee investigating the matter would merge into the bi-partisan joint New Jersey Legislative Select Committee on Investigation, which they would co-chair and would have 12 members. While the committee initially focused on the Bridgegate scandal, it had the power to investigate other allegations against the Christie administration. On January 24, 2014 the members of the bi-partisan committee were announced; eight Assembly representatives, including five Democrats and three Republicans, and four Senators, including three Democrats and one Republican. At the time, 40% of the members of the New Jersey Legislature were Republican. Besides the two Democratic co-chairs, members included Assemblywoman Marlene Caride (D-Bergen), Assemblyman Michael Patrick Carroll (R-Morris), Senator Nia Gill (D-Essex), Senator Linda Greenstein (D-Middlesex), Assembly Majority Leader Louis Greenwald (D-Camden), Assemblywoman Amy Handlin (R-Monmouth), Assemblywoman Valerie Huttle (D-Bergen), Assemblywoman Holly Schepisi (R-Bergen), Assemblywoman Bonnie Watson Coleman (D-Mercer), and an unnamed Republican Senator. On January 27, both houses voted unanimously to combine the investigations, maintaining the partisan balance, and announced Kevin O'Toole's (R-Essex) inclusion despite his mention in a December 5 email from Wildstein to Michael Drewniak. Assemblyman Paul Moriarty (D-4th Legislative) District subsequently replaced Watson.

Input: Consider Input: Question: Did the same person establish the Meridian and Mean time? Passage:Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban Conservatoire of Music and Dance.
