Problem: House music:

The hypnotic electronic dance song "On and On", produced in 1984 by Chicago DJ Jesse Saunders and co-written by Vince Lawrence, had elements that became staples of the early house sound, such as the Roland TB-303 bass synthesizer and minimal vocals as well as a Roland (specifically TR-808) drum machine and Korg (specifically Poly-61) synthesizer. It also utilized the bassline from Player One's disco record "Space Invaders" (1979). "On and On" is sometimes cited as the 'first house record', though other examples from around that time, such as J.M. Silk's "Music is the Key" (1985), have also been cited.

Even though, both Kashmir Shaivism and Advaita Vedanta are non-dual philosophies which give primacy to Universal Consciousness (Chit or Brahman), in Kashmir Shavisim, as opposed to Advaita, all things are a manifestation of this Consciousness. This implies that from the point of view of Kashmir Shavisim, the phenomenal world (Śakti) is real, and it exists and has its being in Consciousness (Chit). Whereas, Advaita holds that Brahman is inactive (niṣkriya) and the phenomenal world is an illusion (māyā). The objective of human life, according to Kashmir Shaivism, is to merge in Shiva or Universal Consciousness, or to realize one's already existing identity with Shiva, by means of wisdom, yoga and grace.
What are dual philosophies?
A: unanswerable


Context and question: Unicode was designed to provide code-point-by-code-point round-trip format conversion to and from any preexisting character encodings, so that text files in older character sets can be naïvely converted to Unicode, and then back and get back the same file. That has meant that inconsistent legacy architectures, such as combining diacritics and precomposed characters, both exist in Unicode, giving more than one method of representing some text. This is most pronounced in the three different encoding forms for Korean Hangul. Since version 3.0, any precomposed characters that can be represented by a combining sequence of already existing characters can no longer be added to the standard in order to preserve interoperability between software using different versions of Unicode.
After what version did it become possible to add preexisting characters?
Answer: unanswerable

Paris' urbanism laws have been under strict control since the early 17th century, particularly where street-front alignment, building height and building distribution is concerned. In recent developments, a 1974-2010 building height limitation of 37 metres (121 ft) was raised to 50 m (160 ft) in central areas and 180 metres (590 ft) in some of Paris' peripheral quarters, yet for some of the city's more central quarters, even older building-height laws still remain in effect. The 210 metres (690 ft) Montparnasse tower was both Paris and France's tallest building until 1973, but this record has been held by the La Défense quarter Tour First tower in Courbevoie since its 2011 construction. A new project for La Defense, called Hermitage Plaza, launched in 2009, proposes to build two towers, 85 and 86 stories or 320 metres high, which would be the tallest buildings in the European Union, just slightly shorter than the Eiffel Tower. They were scheduled for completion in 2019 or 2020, but as of January 2015 construction had not yet begun, and there were questions in the press about the future of the project.
Until 1973, what was Paris; tallest building?
A:
Montparnasse
