Problem: Please answer a question about the following article about Gene:

Hayek's influence on the development of economics is widely acknowledged. Hayek is the second-most frequently cited economist (after Kenneth Arrow) in the Nobel lectures of the prize winners in economics, which is particularly striking since his own lecture was critical of the field of orthodox economics and neo-classical modelisation. A number of Nobel Laureates in economics, such as Vernon Smith and Herbert A. Simon, recognise Hayek as the greatest modern economist. Another Nobel winner, Paul Samuelson, believed that Hayek was worthy of his award but nevertheless claimed that "there were good historical reasons for fading memories of Hayek within the mainstream last half of the twentieth century economist fraternity. In 1931, Hayek's Prices and Production had enjoyed an ultra-short Byronic success. In retrospect hindsight tells us that its mumbo-jumbo about the period of production grossly misdiagnosed the macroeconomics of the 1927–1931 (and the 1931–2007) historical scene". Despite this comment, Samuelson spent the last 50 years of his life obsessed with the problems of capital theory identified by Hayek and Böhm-Bawerk, and Samuelson flatly judged Hayek to have been right and his own teacher, Joseph Schumpeter, to have been wrong on the central economic question of the 20th century, the feasibility of socialist economic planning in a production goods dominated economy.

What Nobel prize winner has spent most of his life studying Hayek's capital theory despite being critical of the man?
Answer: Paul Samuelson


Problem: Construction is currently underway on the Miami Intermodal Center and Miami Central Station, a massive transportation hub servicing Metrorail, Amtrak, Tri-Rail, Metrobus, Greyhound Lines, taxis, rental cars, MIA Mover, private automobiles, bicycles and pedestrians adjacent to Miami International Airport. Completion of the Miami Intermodal Center is expected to be completed by winter 2011, and will serve over 150,000 commuters and travelers in the Miami area. Phase I of Miami Central Station is scheduled to begin service in the spring of 2012, and Phase II in 2013.
What airport is Miami Intermodal Center next to?
The answer is the following: Miami International


Nanjing has a humid subtropical climate (Köppen Cfa) and is under the influence of the East Asian monsoon. The four seasons are distinct, with damp conditions seen throughout the year, very hot and muggy summers, cold, damp winters, and in between, spring and autumn are of reasonable length. Along with Chongqing and Wuhan, Nanjing is traditionally referred to as one of the "Three Furnacelike Cities" along the Yangtze River (长江流域三大火炉) for the perennially high temperatures in the summertime. However, the time from mid-June to the end of July is the plum blossom blooming season in which the meiyu (rainy season of East Asia; literally "plum rain") occurs, during which the city experiences a period of mild rain as well as dampness. Typhoons are uncommon but possible in the late stages of summer and early part of autumn. The annual mean temperature is around 15.46 °C (59.8 °F), with the monthly 24-hour average temperature ranging from 2.4 °C (36.3 °F) in January to 27.8 °C (82.0 °F) in July. Extremes since 1951 have ranged from −14.0 °C (7 °F) on 6 January 1955 to 40.7 °C (105 °F) on 22 August 1959. On average precipitation falls 115 days out of the year, and the average annual rainfall is 1,062 millimetres (42 in). With monthly percent possible sunshine ranging from 37 percent in March to 52 percent in August, the city receives 1,983 hours of bright sunshine annually.
What type of climate does Nanjing enjoy?
a humid subtropical climate


Input: Qing dynasty
Qing China reached its largest extent during the 18th century, when it ruled China proper (eighteen provinces) as well as the areas of present-day Northeast China, Inner Mongolia, Outer Mongolia, Xinjiang and Tibet, at approximately 13 million km2 in size. There were originally 18 provinces, all of which in China proper, but later this number was increased to 22, with Manchuria and Xinjiang being divided or turned into provinces. Taiwan, originally part of Fujian province, became a province of its own in the late 19th century, but was ceded to the Empire of Japan in 1895 following the First Sino-Japanese War. In addition, many surrounding countries, such as Korea (Joseon dynasty), Vietnam frequently paid tribute to China during much of this period. Khanate of Kokand were forced to submit as protectorate and pay tribute to the Qing dynasty in China between 1774 and 1798.

When did Japan take over Taiwan?
Output: 1895


Problem: Please answer a question about the following article about Pharmaceutical industry:
By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.
Who identified the active substance?
A:
John Abel
