Problem: Vocal music in the Renaissance is noted for the flourishing of an increasingly elaborate polyphonic style. The principal liturgical forms which endured throughout the entire Renaissance period were masses and motets, with some other developments towards the end, especially as composers of sacred music began to adopt secular forms (such as the madrigal) for their own designs. Towards the end of the period, the early dramatic precursors of opera such as monody, the madrigal comedy, and the intermedio are seen.
Vocal music in the Renaissance is noted for an increasingly elaborate what?
The answer is the following: polyphonic style

Problem: Child labour has been a consistent struggle for children in Brazil ever since the country was colonized on April 22, 1550 by Pedro Alvares Cabral. Work that many children took part in was not always visible, legal, or paid. Free or slave labour was a common occurrence for many youths and was a part of their everyday lives as they grew into adulthood. Yet due to there being no clear definition of how to classify what a child or youth is, there has been little historical documentation of child labour during the colonial period. Due to this lack of documentation, it is hard to determine just how many children were used for what kinds of work before the nineteenth century. The first documentation of child labour in Brazil occurred during the time of indigenous societies and slave labour where it was found that children were forcibly working on tasks that exceeded their emotional and physical limits. Armando Dias, for example, died in November 1913 whilst still very young, a victim of an electric shock when entering the textile industry where he worked. Boys and girls were victims of industrial accidents on a daily basis.
Who colonized Brazil?
The answer is the following: Pedro Alvares Cabral

Problem: The context for the rise of the public sphere was the economic and social change commonly associated with the Industrial Revolution: "economic expansion, increasing urbanization, rising population and improving communications in comparison to the stagnation of the previous century"." Rising efficiency in production techniques and communication lowered the prices of consumer goods and increased the amount and variety of goods available to consumers (including the literature essential to the public sphere). Meanwhile, the colonial experience (most European states had colonial empires in the 18th century) began to expose European society to extremely heterogeneous cultures, leading to the breaking down of "barriers between cultural systems, religious divides, gender differences and geographical areas".
Was the variety of goods available to consumers increased or decreased by the economic and social change of the Industrial Revolution?
The answer is the following:
increased
