Problem: Child labour:

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.

Problem: Heresy:

In England, the 16th-century European Reformation resulted in a number of executions on charges of heresy. During the thirty-eight years of Henry VIII's reign, about sixty heretics, mainly Protestants, were executed and a rather greater number of Catholics lost their lives on grounds of political offences such as treason, notably Sir Thomas More and Cardinal John Fisher, for refusing to accept the king's supremacy over the Church in England. Under Edward VI, the heresy laws were repealed in 1547 only to be reintroduced in 1554 by Mary I; even so two radicals were executed in Edward's reign (one for denying the reality of the incarnation, the other for denying Christ's divinity). Under Mary, around two hundred and ninety people were burned at the stake between 1555 and 1558 after the restoration of papal jurisdiction. When Elizabeth I came to the throne, the concept of heresy was retained in theory but severely restricted by the 1559 Act of Supremacy and the one hundred and eighty or so Catholics who were executed in the forty-five years of her reign were put to death because they were considered members of "...a subversive fifth column." The last execution of a "heretic" in England occurred under James VI and I in 1612. Although the charge was technically one of "blasphemy" there was one later execution in Scotland (still at that date an entirely independent kingdom) when in 1697 Thomas Aikenhead was accused, among other things, of denying the doctrine of the Trinity.

During what king's reign did 60 Protestants die for heresy?

A: Henry VIII

Problem: Detroit:

Detroit is served by various private schools, as well as parochial Roman Catholic schools operated by the Archdiocese of Detroit. As of 2013[update] there are four Catholic grade schools and three Catholic high schools in the City of Detroit, with all of them in the city's west side. The Archdiocese of Detroit lists a number of primary and secondary schools in the metro area as Catholic education has emigrated to the suburbs. Of the three Catholic high schools in the city, two are operated by the Society of Jesus and the third is co-sponsored by the Sisters, Servants of the Immaculate Heart of Mary and the Congregation of St. Basil.

How many Catholic high schools are in Detroit?

A: three

Problem: Asphalt:

When maintenance is performed on asphalt pavements, such as milling to remove a worn or damaged surface, the removed material can be returned to a facility for processing into new pavement mixtures. The asphalt/bitumen in the removed material can be reactivated and put back to use in new pavement mixes. With some 95% of paved roads being constructed of or surfaced with asphalt, a substantial amount of asphalt pavement material is reclaimed each year. According to industry surveys conducted annually by the Federal Highway Administration and the National Asphalt Pavement Association, more than 99% of the asphalt removed each year from road surfaces during widening and resurfacing projects is reused as part of new pavements, roadbeds, shoulders and embankments.

What percentage of new roadways are surfaced with asphalt?

A:
95%
