Systematic use of child labour was common place in the colonies of European powers between 1650 and 1950. In Africa, colonial administrators encouraged traditional kin-ordered modes of production, that is hiring a household for work not just the adults. Millions of children worked in colonial agricultural plantations, mines and domestic service industries. Sophisticated schemes were promulgated where children in these colonies between the ages of 5–14 were hired as an apprentice without pay in exchange for learning a craft. A system of Pauper Apprenticeship came into practice in the 19th century where the colonial master neither needed the native parents' nor child's approval to assign a child to labour, away from parents, at a distant farm owned by a different colonial master. Other schemes included 'earn-and-learn' programs where children would work and thereby learn. Britain for example passed a law, the so-called Masters and Servants Act of 1899, followed by Tax and Pass Law, to encourage child labour in colonies particularly in Africa. These laws offered the native people the legal ownership to some of the native land in exchange for making labour of wife and children available to colonial government's needs such as in farms and as picannins.
What century did apprenticeships begin to take place?

By about 1910,[note 1] bound collections of empty sleeves with a paperboard or leather cover, similar to a photograph album, were sold as record albums that customers could use to store their records (the term "record album" was printed on some covers). These albums came in both 10-inch and 12-inch sizes. The covers of these bound books were wider and taller than the records inside, allowing the record album to be placed on a shelf upright, like a book, suspending the fragile records above the shelf and protecting them.
What were early record album covers made of?
empty sleeves with a paperboard or leather cover

Often categorised with the New Wave of British Heavy Metal, in 1981 Def Leppard released their second album High 'n' Dry, mixing glam-rock with heavy metal, and helping to define the sound of hard rock for the decade. The follow-up Pyromania (1983), reached number two on the American charts and the singles "Photograph", "Rock of Ages" and "Foolin'", helped by the emergence of MTV, all reached the Top 40. It was widely emulated, particularly by the emerging Californian glam metal scene. This was followed by US acts like Mötley Crüe, with their albums Too Fast for Love (1981) and Shout at the Devil (1983) and, as the style grew, the arrival of bands such as Ratt, White Lion, Twisted Sister and Quiet Riot. Quiet Riot's album Metal Health (1983) was the first glam metal album, and arguably the first heavy metal album of any kind, to reach number one in the Billboard music charts and helped open the doors for mainstream success by subsequent bands.
What were the three Top 40 singles from Def Leppard's Pyromania album?
"Photograph", "Rock of Ages" and "Foolin'"
