Problem: Gothic architecture:

The Basilica of Saint Denis is generally cited as the first truly Gothic building, however the distinction is best reserved for the choir, of which the ambulatory remains intact. Noyon Cathedral, also in France, saw the earliest completion of a rebuilding of an entire cathedral in the new style from 1150 to 1231. While using all those features that came to be known as Gothic, including pointed arches, flying buttresses and ribbed vaulting, the builders continued to employ many of the features and much of the character of Romanesque architecture including round-headed arch throughout the building, varying the shape to pointed where it was functionally practical to do so.

When was the Noyon Cathedral abandoned?

Problem: Gamal Abdel Nasser:

Zakaria Mohieddin, who was Nasser's vice president, said that Nasser gradually changed during his reign. He ceased consulting his colleagues and made more and more of the decisions himself. Although Nasser repeatedly said that a war with Israel will start at a time of his, or Arab, choosing, on 1967 he started a bluffing game "but a successful bluff means your opponent must not know which cards you are holding. In this case Nasser's opponent could see his hand in the mirror and knew he was only holding a pair of deuces" and Nasser knew that his army is not prepared yet. "All of this was out of character...His tendencies in this regard may have been accentuated by diabetes... That was the only rational explanation for his actions in 1967".

What did Mohieddin attribute Nassir's mistakes in 1967 to?
---
A: diabetes


Problem: Montevideo:

Palacio Salvo, at the intersection of 18 de Julio Avenue and Plaza Independencia, was designed by the architect Mario Palanti and completed in 1925. Palanti, an Italian immigrant living in Buenos Aires, used a similar design for his Palacio Barolo in Buenos Aires, Argentina. Palacio Salvo stands 100 metres (330 ft) high, including its antenna. It is built on the former site of the Confitería La Giralda, renowned for being where Gerardo Matos Rodríguez wrote his tango "La Cumparsita" (1917.) Palacio Salvo was originally intended to function as a hotel but is now a mixture of offices and private residences.

How high does the Palacio Salvo stand?
---
A: 100 metres (330 ft) high


Problem: Database:

The first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like "can a customer also be a supplier?", or "if a product is sold with two different forms of packaging, are those the same product or different products?", or "if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.
