Problem: Literature:

Literature consists of written productions, often restricted to those deemed to have artistic or intellectual value. Its Latin root literatura/litteratura (derived itself from littera, letter or handwriting) was used to refer to all written accounts, but intertwined with the roman concept of cultura: learning or cultivation. Literature often uses language differently than ordinary language (see literariness). Literature can be classified according to whether it is fiction or non-fiction and whether it is poetry or prose; it can be further distinguished according to major forms such as the novel, short story or drama; and works are often categorised according to historical periods or their adherence to certain aesthetic features or expectations (genre).

Prose literature can be sub-divided into what formats?
---
A: the novel, short story or drama

Problem: Database:

Having produced a conceptual data model that users are happy with, the next stage is to translate this into a schema that implements the relevant data structures within the database. This process is often called logical database design, and the output is a logical data model expressed in the form of a schema. Whereas the conceptual data model is (in theory at least) independent of the choice of database technology, the logical data model will be expressed in terms of a particular database model supported by the chosen DBMS. (The terms data model and database model are often used interchangeably, but in this article we use data model for the design of a specific database, and database model for the modelling notation used to express that design.)

What form is the input of a logical database design?
---
A: unanswerable

Problem: High-definition television:

The optimum format for a broadcast depends upon the type of videographic recording medium used and the image's characteristics. For best fidelity to the source the transmitted field ratio, lines, and frame rate should match those of the source.

For best fidelity to the source, the transmitted field ratio, lines, and frame rate should match what?
---
A: those of the source

Problem: Bras%C3%ADlia:

The Cathedral of Brasilia in the capital of the Federative Republic of Brazil, is an expression of the architect Oscar Niemeyer. This concrete-framed hyperboloid structure, seems with its glass roof reaching up, open, to the heavens. On 31 May 1970, the Cathedral's structure was finished, and only the 70 m (229.66 ft) diameter of the circular area were visible. Niemeyer's project of Cathedral of Brasilia is based in the hyperboloid of revolution which sections are asymmetric. The hyperboloid structure itself is a result of 16 identical assembled concrete columns. These columns, having hyperbolic section and weighing 90 t, represent two hands moving upwards to heaven. The Cathedral was dedicated on 31 May 1970.

How much does the glass weigh?

A:
