Problem: Please answer a question about the following article about Alaska:
The Trans-Alaska Pipeline can transport and pump up to 2.1 million barrels (330,000 m3) of crude oil per day, more than any other crude oil pipeline in the United States. Additionally, substantial coal deposits are found in Alaska's bituminous, sub-bituminous, and lignite coal basins. The United States Geological Survey estimates that there are 85.4 trillion cubic feet (2,420 km3) of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. Alaska also offers some of the highest hydroelectric power potential in the country from its numerous rivers. Large swaths of the Alaskan coastline offer wind and geothermal energy potential as well.
Alaska's large rivers have potential for what environmentally friendly type of energy production?
A: hydroelectric
Problem: Please answer a question about the following article about Muammar Gaddafi:
Although theoretically a collegial body operating through consensus building, Gaddafi dominated the RCC, although some of the others attempted to constrain what they saw as his excesses. Gaddafi remained the government's public face, with the identities of the other RCC members only being publicly revealed on 10 January 1970. All young men from (typically rural) working and middle-class backgrounds, none had university degrees; in this way they were distinct from the wealthy, highly educated conservatives who previously governed the country.
How many members of the RCC had graduated from university?
A: none

Problem: Please answer a question about the following article about Richmond, Virginia:
On 17 April 1861, five days after the Confederate attack on Fort Sumter, the legislature voted to secede from the United States and joined the Confederacy. Official action came in May, after the Confederacy promised to move its national capital to Richmond. The city was at the end of a long supply line, which made it somewhat difficult to defend, although supplies continued to reach the city by canal and wagon for years, since it was protected by the Army of Northern Virginia and arguably the Confederacy's best troops and commanders. It became the main target of Union armies, especially in the campaigns of 1862 and 1864-5.
Along with 1864-5, what year notably saw US campaigns directed at Richmond?
A:
1862
