Input: Read this: The Gothic vault, unlike the semi-circular vault of Roman and Romanesque buildings, can be used to roof rectangular and irregularly shaped plans such as trapezoids. The other structural advantage is that the pointed arch channels the weight onto the bearing piers or columns at a steep angle. This enabled architects to raise vaults much higher than was possible in Romanesque architecture. While, structurally, use of the pointed arch gave a greater flexibility to architectural form, it also gave Gothic architecture a very different and more vertical visual character than Romanesque.
Question: What type of visual character is forgotten by using the pointed arch?

Output: unanswerable

Input: Read this: During the December 2014 press conference announcing the start of filming, Aston Martin and Eon unveiled the new DB10 as the official car for the film. The DB10 was designed in collaboration between Aston Martin and the filmmakers, with only 10 being produced especially for Spectre as a celebration of the 50th anniversary of the company's association with the franchise. Only eight of those 10 were used for the film, however; the remaining two were used for promotional work. After modifying the Jaguar C-X75 for the film, Williams F1 carried the 007 logo on their cars at the 2015 Mexican Grand Prix, with the team playing host to the cast and crew ahead of the Mexican premiere of the film.

Input: Read this: The Valencia Cathedral was called Iglesia Mayor in the early days of the Reconquista, then Iglesia de la Seo (Seo is from the Latin sedes, i.e., (archiepiscopal) See), and by virtue of the papal concession of 16 October 1866, it was called the Basilica Metropolitana. It is situated in the centre of the ancient Roman city where some believe the temple of Diana stood. In Gothic times, it seems to have been dedicated to the Holy Saviour; the Cid dedicated it to the Blessed Virgin; King James I of Aragon did likewise, leaving in the main chapel the image of the Blessed Virgin, which he carried with him and is reputed to be the one now preserved in the sacristy. The Moorish mosque, which had been converted into a Christian Church by the conqueror, was deemed unworthy of the title of the cathedral of Valencia, and in 1262 Bishop Andrés de Albalat laid the cornerstone of the new Gothic building, with three naves; these reach only to the choir of the present building. Bishop Vidal de Blanes built the chapter hall, and James I added the tower, called El Miguelete because it was blessed on St. Michael's day in 1418. The tower is about 58 m high and topped with a belfry (1660–1736).
Question: How tall is the cathedral's tower?

Output:
58 m
