Problem: Architecture:

In the late 20th century a new concept was added to those included in the compass of both structure and function, the consideration of sustainability, hence sustainable architecture. To satisfy the contemporary ethos a building should be constructed in a manner which is environmentally friendly in terms of the production of its materials, its impact upon the natural and built environment of its surrounding area and the demands that it makes upon non-sustainable power sources for heating, cooling, water and waste management and lighting.

What novel concept was introduced at the end of the 20th century?
---
A: sustainability

Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry. Asthma is classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. It may also be classified as atopic or non-atopic where atopy refers to a predisposition toward developing a type 1 hypersensitivity reaction.
How is asthma classified?
A: according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate


Context and question: Regarding the monastic rules, the Buddha constantly reminds his hearers that it is the spirit that counts. On the other hand, the rules themselves are designed to assure a satisfying life, and provide a perfect springboard for the higher attainments. Monastics are instructed by the Buddha to live as "islands unto themselves". In this sense, living life as the vinaya prescribes it is, as one scholar puts it: "more than merely a means to an end: it is very nearly the end in itself."
The rules themselves are designed to assure a satisfying what?
Answer: life


Question: Heitaro Nakajima, who developed an early digital audio recorder within Japan's national public broadcasting organization NHK in 1970, became general manager of Sony's audio department in 1971. His team developed a digital PCM adaptor audio tape recorder using a Betamax video recorder in 1973. After this, in 1974 the leap to storing digital audio on an optical disc was easily made. Sony first publicly demonstrated an optical digital audio disc in September 1976. A year later, in September 1977, Sony showed the press a 30 cm disc that could play 60 minutes of digital audio (44,100 Hz sampling rate and 16-bit resolution) using MFM modulation. In September 1978, the company demonstrated an optical digital audio disc with a 150-minute playing time, 44,056 Hz sampling rate, 16-bit linear resolution, and cross-interleaved error correction code—specifications similar to those later settled upon for the standard Compact Disc format in 1980. Technical details of Sony's digital audio disc were presented during the 62nd AES Convention, held on 13–16 March 1979, in Brussels. Sony's AES technical paper was published on 1 March 1979. A week later, on 8 March, Philips publicly demonstrated a prototype of an optical digital audio disc at a press conference called "Philips Introduce Compact Disc" in Eindhoven, Netherlands.
Is there an answer to this question: How many minutes could Sony's 1976 optical digital disk play?

Answer: unanswerable


"By May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a thick wall of red mangroves spread mile after mile, some reaching as high as 70 feet (21 m), with intertwined and elevated roots making landing difficult. Very soon, 'many smokes' appeared 'along the whole coast', billowing against the sky, when the Native ancestors of the Seminole spotted the newcomers and spread the alarm by signal fires". The Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida.[full citation needed] Both the Spanish and French established settlements in Florida, with varying degrees of success. In 1559, Don Tristán de Luna y Arellano established a colony at present-day Pensacola, one of the first European settlements in the continental United States, but it was abandoned by 1561.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was founded in 1561?
Ah, so..
