Problem: Please answer a question about the following article about Marshall Islands:
Captain John Charles Marshall and Thomas Gilbert visited the islands in 1788. The islands were named for Marshall on Western charts, although the natives have historically named their home "jolet jen Anij" (Gifts from God). Around 1820, Russian explorer Adam Johann von Krusenstern and the French explorer Louis Isidore Duperrey named the islands after John Marshall, and drew maps of the islands. The designation was repeated later on British maps.[citation needed] In 1824 the crew of the American whaler Globe mutinied and some of the crew put ashore on Mulgrave Island. One year later, the American schooner Dolphin arrived and picked up two boys, the last survivors of a massacre by the natives due to their brutal treatment of the women.:2
Which Russian was involved in naming the Marshall Islands?
A: Adam Johann von Krusenstern
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 developed the method to get epinephrine in it's pure form?
A: Jokichi Takamine
Problem: Please answer a question about the following article about Solar energy:
Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived.
How does the water vapor that rises in warm air turn into clouds?
A: When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds
Problem: Please answer a question about the following article about United Nations Population Fund:
In January 2009 President Barack Obama restored US funding to UNFPA, saying in a public statement that he would "look forward to working with Congress to restore US financial support for the UN Population Fund. By resuming funding to UNFPA, the US will be joining 180 other donor nations working collaboratively to reduce poverty, improve the health of women and children, prevent HIV/AIDS and provide family planning assistance to women in 154 countries." 
Which president began funding UNFPA again?
A:
Barack Obama
