Problem: Under New York State's gradual abolition act of 1799, children of slave mothers were born to be eventually liberated but were held in indentured servitude until their mid-to-late twenties. Together with slaves freed by their masters after the Revolutionary War and escaped slaves, a significant free-black population gradually developed in Manhattan. Under such influential United States founders as Alexander Hamilton and John Jay, the New York Manumission Society worked for abolition and established the African Free School to educate black children. It was not until 1827 that slavery was completely abolished in the state, and free blacks struggled afterward with discrimination. New York interracial abolitionist activism continued; among its leaders were graduates of the African Free School. The city's black population reached more than 16,000 in 1840.
The gradual abolition act in New York was formed in what year?
The answer is the following: 1799

The ad fontes principle also had many applications. The re-discovery of ancient manuscripts brought a more profound and accurate knowledge of ancient philosophical schools such as Epicureanism, and Neoplatonism, whose Pagan wisdom the humanists, like the Church fathers of old, tended, at least initially, to consider as deriving from divine revelation and thus adaptable to a life of Christian virtue. The line from a drama of Terence, Homo sum, humani nihil a me alienum puto (or with nil for nihil), meaning "I am a human being, I think nothing human alien to me", known since antiquity through the endorsement of Saint Augustine, gained renewed currency as epitomising the humanist attitude. The statement, in a play modeled or borrowed from a (now lost) Greek comedy by Menander, may have originated in a lighthearted vein as a comic rationale for an old man's meddling but it quickly became a proverb and throughout the ages was quoted with a deeper meaning, by Cicero and Saint Augustine, to name a few, and most notably by Seneca. Richard Bauman writes:
Who were the Humanists in agreement with about using these manuscripts in their quests for pure Christian living?
Church fathers

Input: Southern Europe
The Nazi regime under Adolf Hitler came to power in 1933, and along with Mussolini's Italy sought to gain control of the continent by the Second World War. Following the Allied victory in the Second World War, Europe was divided by the Iron Curtain. The countries in Southeastern Europe were dominated by the Soviet Union and became communist states. The major non-communist Southern European countries joined a US-led military alliance (NATO) and formed the European Economic Community amongst themselves. The countries in the Soviet sphere of influence joined the military alliance known as the Warsaw Pact and the economic bloc called Comecon. Yugoslavia was neutal.

Who was the leader of Italy when World War II started?

Input: Article: The first Code of Canon Law, 1917, was mostly for the Roman Rite, with limited application to the Eastern Churches. After the Second Vatican Council, (1962 - 1965), another edition was published specifically for the Roman Rite in 1983. Most recently, 1990, the Vatican produced the Code of Canons of the Eastern Churches which became the 1st code of Eastern Catholic Canon Law.

Now answer this question: For whom was a new edition of canon law released in 1983?

Output: the Roman Rite

Problem: In the early 19th century, the role of Utrecht as a fortified town had become obsolete. The fortifications of the Nieuwe Hollandse Waterlinie were moved east of Utrecht. The town walls could now be demolished to allow for expansion. The moats remained intact and formed an important feature of the Zocher plantsoen, an English style landscape park that remains largely intact today. Growth of the city increased when, in 1843, a railway connecting Utrecht to Amsterdam was opened. After that, Utrecht gradually became the main hub of the Dutch railway network. With the industrial revolution finally gathering speed in the Netherlands and the ramparts taken down, Utrecht began to grow far beyond the medieval centre. In 1853, the Dutch government allowed the bishopric of Utrecht to be reinstated by Rome, and Utrecht became the centre of Dutch Catholicism once more. From the 1880s onward neighbourhoods such as Oudwijk, Wittevrouwen, Vogelenbuurt to the East, and Lombok to the West were developed. New middle class residential areas, such as Tuindorp and Oog in Al, were built in the 1920s and 1930s. During this period, several Jugendstil houses and office buildings were built, followed by Rietveld who built the Rietveld Schroder House (1924), and Dudok's construction of the city theater (1941).
In 1843 what brought growth to Utrecht
The answer is the following:
a railway connecting Utrecht to Amsterdam was opened
