Input: Gregorian calendar
Ancient tables provided the sun's mean longitude. Christopher Clavius, the architect of the Gregorian calendar, noted that the tables agreed neither on the time when the sun passed through the vernal equinox nor on the length of the mean tropical year. Tycho Brahe also noticed discrepancies. The Gregorian leap year rule (97 leap years in 400 years) was put forward by Petrus Pitatus of Verona in 1560. He noted that it is consistent with the tropical year of the Alfonsine tables and with the mean tropical year of Copernicus (De revolutionibus) and Reinhold (Prutenic tables). The three mean tropical years in Babylonian sexagesimals as the excess over 365 days (the way they would have been extracted from the tables of mean longitude) were 14,33,9,57 (Alphonsine), 14,33,11,12 (Copernicus) and 14,33,9,24 (Reinhold). All values are the same to two places (14:33) and this is also the mean length of the Gregorian year. Thus Pitatus' solution would have commended itself to the astronomers.

When did Pitatus offer his solution to the leap year problem?
Output: 1560

Input: Article: Despite stiff resistance from the East India lobby in parliament and from the Company's shareholders, the Act passed. It introduced substantial governmental control and allowed British India to be formally under the control of the Crown, but leased back to the Company at 40,000 for two years. Under the Act's most important provision, a governing Council composed of five members was created in Calcutta. The three members nominated by Parliament and representing the Government's interest could, and invariably would, outvote the two Company members. The Council was headed by Warren Hastings, the incumbent Governor, who became the first Governor-General of Bengal, with an ill-defined authority over the Bombay and Madras Presidencies. His nomination, made by the Court of Directors, would in future be subject to the approval of a Council of Four appointed by the Crown. Initially, the Council consisted of Lt. General Sir John Clavering, The Honourable Sir George Monson, Sir Richard Barwell, and Sir Philip Francis.

Now answer this question: How much did the parliament lease British india for to EIC (the lease was for two years)?

Output: 40,000

Here is a question about this article: The U.S. census race definitions says a "black" is a person having origins in any of the black (sub-Saharan) racial groups of Africa. It includes people who indicate their race as "Black, African Am., or Negro" or who provide written entries such as African American, Afro-American, Kenyan, Nigerian, or Haitian. The Census Bureau notes that these classifications are socio-political constructs and should not be interpreted as scientific or anthropological. Most African Americans also have European ancestry in varying amounts; a lesser proportion have some Native American ancestry. For instance, genetic studies of African Americans show an ancestry that is on average 1718% European.
What is the answer to this question: What is the Census definition not based on?
****
So... scientific or anthropological

The problem: Answer a question about this article:
Adolescence is a period frequently marked by increased rights and privileges for individuals. While cultural variation exists for legal rights and their corresponding ages, considerable consistency is found across cultures. Furthermore, since the advent of the Convention on the Rights of the Child in 1989 (children here defined as under 18), almost every country in the world (except the U.S. and South Sudan) has legally committed to advancing an anti-discriminatory stance towards young people of all ages. This includes protecting children against unchecked child labor, enrollment in the military, prostitution, and pornography. In many societies, those who reach a certain age (often 18, though this varies) are considered to have reached the age of majority and are legally regarded as adults who are responsible for their actions. People below this age are considered minors or children. A person below the age of majority may gain adult rights through legal emancipation.
What two countries have not legally committed to advancing an anti-discriminaory stance towards young people?
****
The answer: U.S. and South Sudan
