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.

There have been cases of a variety of speech being deliberately reclassified to serve political purposes. One example is Moldovan. In 1996, the Moldovan parliament, citing fears of "Romanian expansionism", rejected a proposal from President Mircea Snegur to change the name of the language to Romanian, and in 2003 a Moldovan–Romanian dictionary was published, purporting to show that the two countries speak different languages. Linguists of the Romanian Academy reacted by declaring that all the Moldovan words were also Romanian words; while in Moldova, the head of the Academy of Sciences of Moldova, Ion Bărbuţă, described the dictionary as a politically motivated "absurdity".
When was the Romanian-Academy dictionary published?
A: unanswerable

Asphalt/bitumen is typically stored and transported at temperatures around 150 °C (302 °F). Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity; upon delivery, these lighter materials are separated out of the mixture. This mixture is often called "bitumen feedstock", or BFS. Some dump trucks route the hot engine exhaust through pipes in the dump body to keep the material warm. The backs of tippers carrying asphalt/bitumen, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Diesel oil is no longer used as a release agent due to environmental concerns.
To retain liquidity, what is sometimes mixed in with engine exhaust?
A: unanswerable

The Tristan Song Project was a collaboration between St Mary's School and amateur composers in England, led by music teacher Tony Triggs. It began in 2010 and involved St Mary's pupils writing poems and Tony Triggs providing musical settings by himself and his pupils. A desktop publication entitled Rockhopper Penguins and Other Songs (2010) embraced most of the songs completed that year and funded a consignment of guitars to the School. In February 2013 the Tristan Post Office issued a set of four Song Project stamps featuring island musical instruments and lyrics from Song Project songs about Tristan's volcano and wildlife. In 2014 the Project broadened its scope and continues as the International Song Project.
Which project was led by Rockhopper Penguins?
