Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, which requires verifying the account, normally through a mobile phone. When YouTube was launched in 2005, it was possible to upload long videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films. The 10-minute limit was increased to 15 minutes in July 2010. If an up-to-date browser version is used, videos greater than 20 GB can be uploaded.

QUES: By 1836, the Duchess's brother, Leopold, who had been King of the Belgians since 1831, hoped to marry his niece to his nephew, Prince Albert of Saxe-Coburg and Gotha. Leopold, Victoria's mother, and Albert's father (Ernest I, Duke of Saxe-Coburg and Gotha) were siblings. Leopold arranged for Victoria's mother to invite her Coburg relatives to visit her in May 1836, with the purpose of introducing Victoria to Albert. William IV, however, disapproved of any match with the Coburgs, and instead favoured the suit of Prince Alexander of the Netherlands, second son of the Prince of Orange. Victoria was aware of the various matrimonial plans and critically appraised a parade of eligible princes. According to her diary, she enjoyed Albert's company from the beginning. After the visit she wrote, "[Albert] is extremely handsome; his hair is about the same colour as mine; his eyes are large and blue, and he has a beautiful nose and a very sweet mouth with fine teeth; but the charm of his countenance is his expression, which is most delightful." Alexander, on the other hand, was "very plain".

QUES: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
What time period did the colonialism of the Sahara begin?

ANS: 19th century


Many adaptations of the instrument have been done to cater to the special needs of Indian Carnatic music. In Indian classical music and Indian light music, the mandolin, which bears little resemblance to the European mandolin, is usually tuned E-B-E-B. As there is no concept of absolute pitch in Indian classical music, any convenient tuning maintaining these relative pitch intervals between the strings can be used. Another prevalent tuning with these intervals is C-G-C-G, which corresponds to Sa-Pa-Sa-Pa in the Indian carnatic classical music style. This tuning corresponds to the way violins are tuned for carnatic classical music. This type of mandolin is also used in Bhangra, dance music popular in Punjabi culture.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Many adaptations of the instruments were done to not cater to what type of music?
Ah, so.. unanswerable

Context and question: Since the canons of criticism are highly susceptible to interpretation, and at times even contradict each other, they may be employed to justify a result that fits the textual critic's aesthetic or theological agenda. Starting in the 19th century, scholars sought more rigorous methods to guide editorial judgment. Best-text editing (a complete rejection of eclecticism) became one extreme. Stemmatics and copy-text editing – while both eclectic, in that they permit the editor to select readings from multiple sources – sought to reduce subjectivity by establishing one or a few witnesses presumably as being favored by "objective" criteria.[citation needed] The citing of sources used, and alternate readings, and the use of original text and images helps readers and other critics determine to an extent the depth of research of the critic, and to independently verify their work.
The editor sought to raise subjectivity by what?
