Problem: Salts of many oxidation states of uranium are water-soluble and may be studied in aqueous solutions. The most common ionic forms are U3+ (brown-red), U4+ (green), UO+
2 (unstable), and UO2+
2 (yellow), for U(III), U(IV), U(V), and U(VI), respectively. A few solid and semi-metallic compounds such as UO and US exist for the formal oxidation state uranium(II), but no simple ions are known to exist in solution for that state. Ions of U3+ liberate hydrogen from water and are therefore considered to be highly unstable. The UO2+
2 ion represents the uranium(VI) state and is known to form compounds such as uranyl carbonate, uranyl chloride and uranyl sulfate. UO2+
2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate.
What common complex is formed by the UO2+ 2 ion with organic chelating agents?
The answer is the following: uranyl acetate


The Museo Torres García is located in the Old Town, and exhibits Joaquín Torres García's unusual portraits of historical icons and cubist paintings akin to those of Picasso and Braque. The museum was established by Manolita Piña Torres, the widow of Torres Garcia, after his death in 1949. She also set up the García Torres Foundation, a private non-profit organization that organizes the paintings, drawings, original writings, archives, objects and furniture designed by the painter as well as the photographs, magazines and publications related to him.
Who established The Museo Torres Garcia?
Manolita Piña Torres


Input: Modern history
In 1912, the Republic of China was established and Sun Yat-sen was inaugurated in Nanjing as the first Provisional President. But power in Beijing already had passed to Yuan Shikai, who had effective control of the Beiyang Army, the most powerful military force in China at the time. To prevent civil war and possible foreign intervention from undermining the infant republic, leaders agreed to Army's demand that China be united under a Beijing government. On March 10, in Beijing, Shikai was sworn in as the second Provisional President of the Republic of China.

Who had control of the Beiyang army?
Output: Yuan Shikai


Input: Article: There are two types of transistors, which have slight differences in how they are used in a circuit. A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor, the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.

Now answer this question: What are the components of a field-effect transistor?

Output: gate, source, and drain


Article: The Presbyterian Church in Taiwan (PCT) is by far the largest Protestant denomination in Taiwan, with some 238,372 members as of 2009 (including a majority of the island's aborigines). English Presbyterian missionary James Laidlaw Maxwell established the first Presbyterian church in Tainan in 1865. His colleague George Leslie Mackay, of the Canadian Presbyterian Mission, was active in Danshui and north Taiwan from 1872 to 1901; he founded the island's first university and hospital, and created a written script for Taiwanese Minnan. The English and Canadian missions joined together as the PCT in 1912. One of the few churches permitted to operate in Taiwan through the era of Japanese rule (1895–1945), the PCT experienced rapid growth during the era of Guomindang-imposed martial law (1949–1987), in part due to its support for democracy, human rights, and Taiwan independence. Former ROC president Lee Teng-hui (in office 1988–2000) is a Presbyterian.

Question: In what era did The Presbyterian Church in Taiwan experience a large growth in members?
Ans: era of Guomindang


Input: Queen Victoria
In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.

What annoyed the King about the way Victoria was received at her stops?
Output:
enthusiastically welcomed in each
