New York City has more than 2,000 arts and cultural organizations and more than 500 art galleries of all sizes. The city government funds the arts with a larger annual budget than the National Endowment for the Arts. Wealthy business magnates in the 19th century built a network of major cultural institutions, such as the famed Carnegie Hall and The Metropolitan Museum of Art, that would become internationally established. The advent of electric lighting led to elaborate theater productions, and in the 1880s, New York City theaters on Broadway and along 42nd Street began featuring a new stage form that became known as the Broadway musical. Strongly influenced by the city's immigrants, productions such as those of Harrigan and Hart, George M. Cohan, and others used song in narratives that often reflected themes of hope and ambition.
About how many cultural and artistic organizations are in New York City?
****
The answer: 2,000

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 514 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.
How many children were employed on colonial plantations?
****
The answer: Millions
