Problem: Post-punk:

During the initial punk era, a variety of entrepreneurs interested in local punk-influenced music scenes began founding independent record labels, including Rough Trade (founded by record shop owner Geoff Travis) and Factory (founded by Manchester-based television personality Tony Wilson). By 1977, groups began pointedly pursuing methods of releasing music independently , an idea disseminated in particular by the Buzzcocks' release of their Spiral Scratch EP on their own label as well as the self-released 1977 singles of Desperate Bicycles. These DIY imperatives would help form the production and distribution infrastructure of post-punk and the indie music scene that later blossomed in the mid-1980s.

When did releasing music indepentently really hit popularity?

A: 1977


Problem: Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers and scientists to tap into the clunky database. When the archive reached its fifth anniversary, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley.
What medium was originally used to keep California's data?

Answer: unanswerable


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
What term can be used to refer to the usable spectrum of an antennas frequency?
A: bandwidth


Context and question: Time has long been a major subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. Some simple definitions of time include "time is what clocks measure", which is a problematically vague and self-referential definition that utilizes the device used to measure the subject as the definition of the subject, and "time is what keeps everything from happening at once", which is without substantive meaning in the absence of the definition of simultaneity in the context of the limitations of human sensation, observation of events, and the perception of such events.
What fields use measuring systems to check the weight of their products?
Answer: unanswerable


Question: Increasing urbanisation of India in 7th and 6th centuries BCE led to the rise of new ascetic or shramana movements which challenged the orthodoxy of rituals. Mahavira (c. 549–477 BC), proponent of Jainism, and Buddha (c. 563-483), founder of Buddhism were the most prominent icons of this movement. Shramana gave rise to the concept of the cycle of birth and death, the concept of samsara, and the concept of liberation. Buddha found a Middle Way that ameliorated the extreme asceticism found in the Sramana religions.
Is there an answer to this question: Who was the founder of Jainism?

Answer: Mahavira


Though almost any variety of acoustic mandolin might be adequate for Irish traditional music, virtually all Irish players prefer flat-backed instruments with oval sound holes to the Italian-style bowl-back mandolins or the carved-top mandolins with f-holes favoured by bluegrass mandolinists. The former are often too soft-toned to hold their own in a session (as well as having a tendency to not stay in place on the player's lap), whilst the latter tend to sound harsh and overbearing to the traditional ear. The f-hole mandolin, however, does come into its own in a traditional session, where its brighter tone cuts through the sonic clutter of a pub. Greatly preferred for formal performance and recording are flat-topped "Irish-style" mandolins (reminiscent of the WWI-era Martin Army-Navy mandolin) and carved (arch) top mandolins with oval soundholes, such as the Gibson A-style of the 1920s.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  Why is it said that the Italian style can hold their own session?
Ah, so..
unanswerable
