Input: MP3
Further work on MPEG audio was finalized in 1994 as part of the second suite of MPEG standards, MPEG-2, more formally known as international standard ISO/IEC 13818-3 (a.k.a. MPEG-2 Part 3 or backwards compatible MPEG-2 Audio or MPEG-2 Audio BC), originally published in 1995. MPEG-2 Part 3 (ISO/IEC 13818-3) defined additional bit rates and sample rates for MPEG-1 Audio Layer I, II and III. The new sampling rates are exactly half that of those originally defined in MPEG-1 Audio. This reduction in sampling rate serves to cut the available frequency fidelity in half while likewise cutting the bitrate by 50%. MPEG-2 Part 3 also enhanced MPEG-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel.

Apart from cutting the frequency fidelity in half, what else was cut in half?
Output: bitrate

Input: Child labour
Small-scale artisanal mining of gold is another source of dangerous child labour in poor rural areas in certain parts of the world. This form of mining uses labour-intensive and low-tech methods. It is informal sector of the economy. Human Rights Watch group estimates that about 12 percent of global gold production comes from artisanal mines. In west Africa, in countries such as Mali - the third largest exporter of gold in Africa - between 20,000 and 40,000 children work in artisanal mining. Locally known as orpaillage, children as young as 6 years old work with their families. These children and families suffer chronic exposure to toxic chemicals including mercury, and do hazardous work such as digging shafts and working underground, pulling up, carrying and crushing the ore. The poor work practices harm the long term health of children, as well as release hundreds of tons of mercury every year into local rivers, ground water and lakes. Gold is important to the economy of Mali and Ghana. For Mali, it is the second largest earner of its export revenue. For many poor families with children, it is the primary and sometimes the only source of income.

Why is gold vital to the people of Mali?
Output: it is the second largest earner of its export revenue

Input: Marshall Islands
The Japanese enlarged administration and appointed local leaders, which weakened the authority of local traditional leaders. Japan also tried to change the social organization in the islands from Matrilineality to the Japanese Patriarchal system, but with no success. Moreover, during the 1930s, one third of all land up to the high water level was declared the property of the Japanese government. On the archipelago, before it banned foreign traders, the activities of Catholic and Protestant missionaries were allowed. Indigenous people were educated in Japanese schools, and studied Japanese language and Japanese culture. This policy was the government strategy not only in the Marshall Islands, but on all the other mandated territories in Micronesia. On March 27, 1933, Japan handed in its notice at the League of Nations, but continued to manage the islands, and in the late 1930s began building air bases on several atolls. The Marshall Islands were in an important geographical position, being the easternmost point in Japan's defensive ring at the beginning of World War II.

What system of social organization was used in Japan?
Output: the Japanese Patriarchal system

Input: Premier League
The Football Association Premier League Ltd (FAPL) is operated as a corporation and is owned by the 20 member clubs. Each club is a shareholder, with one vote each on issues such as rule changes and contracts. The clubs elect a chairman, chief executive, and board of directors to oversee the daily operations of the league. The current chairman is Sir Dave Richards, who was appointed in April 1999, and the chief executive is Richard Scudamore, appointed in November 1999. The former chairman and chief executive, John Quinton and Peter Leaver, were forced to resign in March 1999 after awarding consultancy contracts to former Sky executives Sam Chisholm and David Chance. The Football Association is not directly involved in the day-to-day operations of the Premier League, but has veto power as a special shareholder during the election of the chairman and chief executive and when new rules are adopted by the league.

Who is the current chairman of the Premier League?
Output:
Sir Dave Richards
