Problem: Please answer a question about the following article about Zinc:
The name of the metal was probably first documented by Paracelsus, a Swiss-born German alchemist, who referred to the metal as "zincum" or "zinken" in his book Liber Mineralium II, in the 16th century. The word is probably derived from the German zinke, and supposedly meant "tooth-like, pointed or jagged" (metallic zinc crystals have a needle-like appearance). Zink could also imply "tin-like" because of its relation to German zinn meaning tin. Yet another possibility is that the word is derived from the Persian word سنگ seng meaning stone. The metal was also called Indian tin, tutanego, calamine, and spinter.
Who is attributed as first documenting zinc?
A: Paracelsus
Problem: Please answer a question about the following article about Richmond, Virginia:
As the primary former Capital of the Confederate States of America, Richmond is home to many museums and battlefields of the American Civil War. Near the riverfront is the Richmond National Battlefield Park Visitors Center and the American Civil War Center at Historic Tredegar, both housed in the former buildings of the Tredegar Iron Works, where much of the ordnance for the war was produced. In Court End, near the Virginia State Capitol, is the Museum of the Confederacy, along with the Davis Mansion, also known as the White House of the Confederacy; both feature a wide variety of objects and material from the era. The temporary home of former Confederate General Robert E. Lee still stands on Franklin Street in downtown Richmond. The history of slavery and emancipation are also increasingly represented: there is a former slave trail along the river that leads to Ancarrow's Boat Ramp and Historic Site which has been developed with interpretive signage, and in 2007, the Reconciliation Statue was placed in Shockoe Bottom, with parallel statues placed in Liverpool and Benin representing points of the Triangle Trade.
Where are the Reconciliation Statues outside Richmond located?
A: Liverpool and Benin
Problem: Please answer a question about the following article about Railway electrification system:
In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic  so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.
What year could be marked as year when electric railways more efficient than diesel ones?
A: 1965
Problem: Please answer a question about the following article about British Isles:
Another body established under the Good Friday Agreement, the British–Irish Council, is made up of all of the states and territories of the British Isles. The British–Irish Parliamentary Assembly (Irish: Tionól Pharlaiminteach na Breataine agus na hÉireann) predates the British–Irish Council and was established in 1990. Originally it comprised 25 members of the Oireachtas, the Irish parliament, and 25 members of the parliament of the United Kingdom, with the purpose of building mutual understanding between members of both legislatures. Since then the role and scope of the body has been expanded to include representatives from the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly, the States of Jersey, the States of Guernsey and the High Court of Tynwald (Isle of Man).
How many members of the United Kingdom Parliament were in the British-Irish Parliamentary Assembly originally?
A:
25
