Article: 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.

Question: Who developed the method to obtain epinephrine in a pure state?
Ans: Jokichi Takamine

Article: EU member countries have shown support for ambitious renewable energy goals. In 2010, Eurobarometer polled the twenty-seven EU member states about the target "to increase the share of renewable energy in the EU by 20 percent by 2020". Most people in all twenty-seven countries either approved of the target or called for it to go further. Across the EU, 57 percent thought the proposed goal was "about right" and 16 percent thought it was "too modest." In comparison, 19 percent said it was "too ambitious".

Question: Who has shown support for ambitious renewable energy goals?
Ans: EU member countries

Article: Between 1872 and 1905, a series of protests took place in response to the sale of concessions to foreigners by Nasser od Din and Mozaffar od Din shahs of Qajar, and led to the Iranian Constitutional Revolution. The first Iranian Constitution and the first national parliament of Iran were founded in 1906, through the ongoing revolution. The Constitution included the official recognition of Iran's three religious minorities, namely Christians, Zoroastrians, and Jews, which has remained a basis in the legislation of Iran since then.

Question: The first national parliament of Iran was founded in what year?
Ans: in 1906

Article: This is not surprising, though: While the greatest number of slaves imported from Africa were sent to Brazil, totalizing roughly 3.5 million people, they lived in such miserable conditions that male African Y-DNA there is significantly rare due to the lack of resources and time involved with raising of children, so that most African descent originarily came from relations between white masters and female slaves. From the last decades of the Empire until the 1950s, the proportion of the white population increased significantly while Brazil welcomed 5.5 million immigrants between 1821 and 1932, not much behind its neighbor Argentina with 6.4 million, and it received more European immigrants in its colonial history than the United States. Between 1500 and 1760, 700.000 Europeans settled in Brazil, while 530.000 Europeans settled in the United States for the same given time. Thus, the historical construction of race in Brazilian society dealt primarily with gradations between persons of majoritarily European ancestry and little minority groups with otherwise lower quantity therefrom in recent times.

Question: What conditions did the African slaves in Brazil live in?
Ans:
miserable
