Input: Read this: The system was later extended to cover larger ranges and some of its practical shortcomings were addressed by the Austrian scientist Josef Maria Eder (18551944) and Flemish-born botanist Walter Hecht (de) (18961960), (who, in 1919/1920, jointly developed their EderHecht neutral wedge sensitometer measuring emulsion speeds in EderHecht grades). Still, it remained difficult for manufactures to reliably determine film speeds, often only by comparing with competing products, so that an increasing number of modified semi-Scheiner-based systems started to spread, which no longer followed Scheiner's original procedures and thereby defeated the idea of comparability.
Question: What made comparability a more common option?

Output: unanswerable

Input: Read this: The earliest evidence of cotton use in South Asia has been found at the site of Mehrgarh, Pakistan, where cotton threads have been found preserved in copper beads; these finds have been dated to Neolithic (between 6000 and 5000 BCE). Cotton cultivation in the region is dated to the Indus Valley Civilization, which covered parts of modern eastern Pakistan and northwestern India between 3300 and 1300 BCE The Indus cotton industry was well-developed and some methods used in cotton spinning and fabrication continued to be used until the industrialization of India. Between 2000 and 1000 BC cotton became widespread across much of India. For example, it has been found at the site of Hallus in Karnataka dating from around 1000 BC.
Question: Until what event did the ancient methods of spinning and fabrication of cotton last?

Output: industrialization

Input: Read this: Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a similar term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. The major time divisions of classical music are as follows: the early music period, which includes the Medieval (5001400) and the Renaissance (14001600) eras; the Common practice period, which includes the Baroque (16001750), Classical (17501820), and Romantic eras (18041910); and the 20th century (19012000) which includes the modern (18901930) that overlaps from the late 19th-century, the high modern (mid 20th-century), and contemporary or postmodern (19752015) eras.[citation needed]
Question: Classical music is rooted in what kind of tradition?

Output: Western music

Input: Read this: After the Indian Rebellion of 1857, the British East India Company, which had ruled much of India, was dissolved, and Britain's possessions and protectorates on the Indian subcontinent were formally incorporated into the British Empire. The Queen had a relatively balanced view of the conflict, and condemned atrocities on both sides. She wrote of "her feelings of horror and regret at the result of this bloody civil war", and insisted, urged on by Albert, that an official proclamation announcing the transfer of power from the company to the state "should breathe feelings of generosity, benevolence and religious toleration". At her behest, a reference threatening the "undermining of native religions and customs" was replaced by a passage guaranteeing religious freedom.
Question: What ruler was dissolved after the Indian Rebellion in 1857?

Output:
British East India Company
