Problem: Please answer a question about the following article about Airport:
Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s.
Why did airport construction boom during the 1960s?
A: increase in jet aircraft traffic
Problem: Please answer a question about the following article about Muslim world:
Ibn Tufail (Abubacer) and Ibn al-Nafis were pioneers of the philosophical novel. Ibn Tufail wrote the first Arabic novel Hayy ibn Yaqdhan (Philosophus Autodidactus) as a response to Al-Ghazali's The Incoherence of the Philosophers, and then Ibn al-Nafis also wrote a novel Theologus Autodidactus as a response to Ibn Tufail's Philosophus Autodidactus. Both of these narratives had protagonists (Hayy in Philosophus Autodidactus and Kamil in Theologus Autodidactus) who were autodidactic feral children living in seclusion on a desert island, both being the earliest examples of a desert island story. However, while Hayy lives alone with animals on the desert island for the rest of the story in Philosophus Autodidactus, the story of Kamil extends beyond the desert island setting in Theologus Autodidactus, developing into the earliest known coming of age plot and eventually becoming the first example of a science fiction novel.
What person wrote The Incoherence of the Philosophers?
A: Al-Ghazali
Problem: Please answer a question about the following article about Queen Victoria:
Internationally, Victoria took a keen interest in the improvement of relations between France and Britain. She made and hosted several visits between the British royal family and the House of Orleans, who were related by marriage through the Coburgs. In 1843 and 1845, she and Albert stayed with King Louis Philippe I at château d'Eu in Normandy; she was the first British or English monarch to visit a French one since the meeting of Henry VIII of England and Francis I of France on the Field of the Cloth of Gold in 1520. When Louis Philippe made a reciprocal trip in 1844, he became the first French king to visit a British sovereign. Louis Philippe was deposed in the revolutions of 1848, and fled to exile in England. At the height of a revolutionary scare in the United Kingdom in April 1848, Victoria and her family left London for the greater safety of Osborne House, a private estate on the Isle of Wight that they had purchased in 1845 and redeveloped. Demonstrations by Chartists and Irish nationalists failed to attract widespread support, and the scare died down without any major disturbances. Victoria's first visit to Ireland in 1849 was a public relations success, but it had no lasting impact or effect on the growth of Irish nationalism.
Where did Victoria and her family retreat to safety during a conflict in 1848? 
A: Osborne House
Problem: Please answer a question about the following article about Tuvalu:
From 1996 to 2002, Tuvalu was one of the best-performing Pacific Island economies and achieved an average real gross domestic product (GDP) growth rate of 5.6% per annum. Since 2002 economic growth has slowed, with GDP growth of 1.5% in 2008. Tuvalu was exposed to rapid rises in world prices of fuel and food in 2008, with the level of inflation peaking at 13.4%. The International Monetary Fund 2010 Report on Tuvalu estimates that Tuvalu experienced zero growth in its 2010 GDP, after the economy contracted by about 2% in 2009. On 5 August 2012, the Executive Board of the International Monetary Fund (IMF) concluded the Article IV consultation with Tuvalu, and assessed the economy of Tuvalu: "A slow recovery is underway in Tuvalu, but there are important risks. GDP grew in 2011 for the first time since the global financial crisis, led by the private retail sector and education spending. We expect growth to rise slowly". The IMF 2014 Country Report noted that real GDP growth in Tuvalu had been volatile averaging only 1 percent in the past decade. The 2014 Country Report describes economic growth prospects as generally positive as the result of large revenues from fishing licenses, together with substantial foreign aid.
 What has been the GDP of Tuvalu in 2008?
A:
1.5%
