Here is a question about this article: As the 20th century came to a close, Gaddafi increasingly rejected Arab nationalism, frustrated by the failure of his Pan-Arab ideals; instead he turned to Pan-Africanism, emphasising Libya's African identity. From 1997 to 2000, Libya initiated cooperative agreements or bilateral aid arrangements with 10 African states, and in 1999 joined the Community of Sahel-Saharan States. In June 1999, Gaddafi visited Mandela in South Africa, and the following month attended the OAU summit in Algiers, calling for greater political and economic integration across the continent and advocating the foundation of a United States of Africa. He became one of the founders of the African Union (AU), initiated in July 2002 to replace the OAU; at the opening ceremonies, he proclaimed that African states should reject conditional aid from the developed world, a direct contrast to the message of South African President Thabo Mbeki. At the third AU summit, held in Libya in July 2005, he called for a greater level of integration, advocating a single AU passport, a common defence system and a single currency, utilising the slogan: "The United States of Africa is the hope." In June 2005, Libya joined the Common Market for Eastern and Southern Africa (COMESA), and in August 2008 Gaddafi was proclaimed "King of Kings" by an assembled committee of traditional African leaders. On 1 February 2009, his "coronation ceremony" was held in Addis Ababa, Ethiopia, coinciding with Gaddafi's election as AU chairman for a year.
What is the answer to this question: What is COMESA?
****
So... Common Market for Eastern and Southern Africa

After two forays into more serious dramatic films, Spielberg then directed the third Indiana Jones film, 1989's Indiana Jones and the Last Crusade. Once again teaming up with Lucas and Ford, Spielberg also cast actor Sean Connery in a supporting role as Indy's father. The film earned generally positive reviews and was another box office success, becoming the highest grossing film worldwide that year; its total box office receipts even topped those of Tim Burton's much-anticipated film Batman, which had been the bigger hit domestically. Also in 1989, he re-united with actor Richard Dreyfuss for the romantic comedy-drama Always, about a daredevil pilot who extinguishes forest fires. Spielberg's first romantic film, Always was only a moderate success and had mixed reviews.

The answer: a daredevil pilot who extinguishes forest fires


Problem: Please answer a question about the following article about Liberia:
Following a peak in growth in 1979, the Liberian economy began a steady decline due to economic mismanagement following the 1980 coup. This decline was accelerated by the outbreak of civil war in 1989; GDP was reduced by an estimated 90% between 1989 and 1995, one of the fastest declines in history. Upon the end of the war in 2003, GDP growth began to accelerate, reaching 9.4% in 2007. The global financial crisis slowed GDP growth to 4.6% in 2009, though a strengthening agricultural sector led by rubber and timber exports increased growth to 5.1% in 2010 and an expected 7.3% in 2011, making the economy one of the 20 fastest growing in the world.
When did the Liberian economy hit it's peak growth?
A: 1979

On July 6, 2001, he pleaded guilty to 15 counts of espionage in the United States District Court for the Eastern District of Virginia. His spying activities have been described by the US Department of Justice's Commission for the Review of FBI Security Programs as "possibly the worst intelligence disaster in U.S. history".

Problem: Child labour accounts for 22% of the workforce in Asia, 32% in Africa, 17% in Latin America, 1% in the US, Canada, Europe and other wealthy nations. The proportion of child labourers varies greatly among countries and even regions inside those countries. Africa has the highest percentage of children aged 5–17 employed as child labour, and a total of over 65 million. Asia, with its larger population, has the largest number of children employed as child labour at about 114 million. Latin America and Caribbean region have lower overall population density, but at 14 million child labourers has high incidence rates too.
In Asia how many millions of children are employed?
The answer is the following: 114


Input: Article: Because of the distance of Neptune from Earth, its angular diameter only ranges from 2.2 to 2.4 arcseconds, the smallest of the Solar System planets. Its small apparent size makes it challenging to study it visually. Most telescopic data was fairly limited until the advent of Hubble Space Telescope (HST) and large ground-based telescopes with adaptive optics (AO). The first scientifically useful observation of Neptune from ground-based telescopes using adaptive optics, was commenced in 1997 from Hawaii. Neptune is currently entering its spring and summer season and has been shown to be heating up, with increased atmospheric activity and brightness as a consequence. Combined with technological advancements, ground-based telescopes with adaptive optics are recording increasingly more detailed images of this Outer Planet. Both the HST and AO telescopes on Earth has made many new discoveries within the Solar System since the mid-1990s, with a large increase in the number of known satellites and moons around the Outer Planets for example. In 2004 and 2005, five new small satellites of Neptune with diameters between 38 and 61 kilometres were discovered.

Now answer this question: When was the first useful observation of Neptune from the ground?

Output:
1997
