Input: Article: The DIN system, officially DIN standard 4512 by Deutsches Institut fur Normung (but still named Deutscher Normenausschu (DNA) at this time), was published in January 1934. It grew out of drafts for a standardized method of sensitometry put forward by Deutscher Normenausschu fur Phototechnik as proposed by the committee for sensitometry of the Deutsche Gesellschaft fur photographische Forschung since 1930 and presented by Robert Luther (de) (18681945) and Emanuel Goldberg (18811970) at the influential VIII. International Congress of Photography (German: Internationaler Kongre fur wissenschaftliche und angewandte Photographie) held in Dresden from August 3 to 8, 1931.

Now answer this question: What was proposed at the VIII International Congress of Photography?

Output: a standardized method of sensitometry

Input: Article: Georgian architecture is characterized by its proportion and balance; simple mathematical ratios were used to determine the height of a window in relation to its width or the shape of a room as a double cube. Regularity, as with ashlar (uniformly cut) stonework, was strongly approved, imbuing symmetry and adherence to classical rules: the lack of symmetry, where Georgian additions were added to earlier structures remaining visible, was deeply felt as a flaw, at least before Nash began to introduce it in a variety of styles. Regularity of housefronts along a street was a desirable feature of Georgian town planning. Until the start of the Gothic Revival in the early 19th century, Georgian designs usually lay within the Classical orders of architecture and employed a decorative vocabulary derived from ancient Rome or Greece.

Now answer this question: What decorative vocabulary did Georgian designs draw from?

Output: ancient Rome or Greece

Input: Article: A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance. An example would be the Moonlight towers in Austin, Texas, where the elevator holds only one person and equipment for maintenance. The Glasgow Tower an observation tower in Glasgow, Scotland also makes use of two climbing elevators.

Now answer this question: What defines a climbing elevator?

Output:
a self-ascending elevator with its own propulsion
