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.

What record label was never independent?

Problem: The state is well known for its handicrafts. The carpets, leather works, shawls, metalware, woodwork and paintings are worth appreciating. Pashmina shawls are a product that is highly in demand in Himachal and all over the country. Himachali caps are famous art work of the people. Extreme cold winters of Himachal necessitated wool weaving. Nearly every household in Himachal owns a pit-loom. Wool is considered as pure and is used as a ritual cloth. The well-known woven object is the shawl, ranging from fine pashmina to the coarse desar. Kullu is famous for its shawls with striking patterns and vibrant colours. Kangra and Dharamshala are famous for Kangra miniature paintings.
What is Kullu famous for?

Answer: shawls with striking patterns and vibrant colours


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The term "Sumerian" is the common name given to the ancient non-Semitic inhabitants of Mesopotamia, Sumer, by the Semitic Akkadians. The Sumerians referred to themselves as ùĝ saĝ gíg-ga (cuneiform: 𒌦 𒊕 𒈪 𒂵), phonetically /uŋ saŋ giga/, literally meaning "the black-headed people", and to their land as ki-en-gi(-r) ('place' + 'lords' + 'noble'), meaning "place of the noble lords". The Akkadian word Shumer may represent the geographical name in dialect, but the phonological development leading to the Akkadian term šumerû is uncertain. Hebrew Shinar, Egyptian Sngr, and Hittite Šanhar(a), all referring to southern Mesopotamia, could be western variants of Shumer.
What did the term Shumer lead to?
A: unanswerable


Context and question: The importation of slaves was made illegal in 1792. Governor Robert Patton (1802–1807) recommended that the company import Chinese labour to supplement the rural workforce. The coolie labourers arrived in 1810, and their numbers reached 600 by 1818. Many were allowed to stay, and their descendents became integrated into the population. An 1814 census recorded 3,507 people on the island.
How many coolie labourers were on the island by 1818?
Answer: 600


Question: Despite the lack of a coastline, Punjab is the most industrialised province of Pakistan; its manufacturing industries produce textiles, sports goods, heavy machinery, electrical appliances, surgical instruments, vehicles, auto parts, metals, sugar mill plants, aircraft, cement, agricultural machinery, bicycles and rickshaws, floor coverings, and processed foods. In 2003, the province manufactured 90% of the paper and paper boards, 71% of the fertilizers, 69% of the sugar and 40% of the cement of Pakistan.
Is there an answer to this question: Which province has an extended coastline?

Answer: unanswerable


An early advantage of AC is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic "universal" AC/DC motor to be largely replaced with the three-phase induction motor fed by a variable frequency drive, a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What taps can provide lighting supply?
Ah, so..
low-voltage transformer windings
