Input: Richmond, Virginia
Three years later, as March 1865 ended, the Confederate capitol became indefensible. On March 25, Confederate General John B. Gordon's desperate attack on Fort Stedman east of Petersburg failed. On April 1, General Philip Sheridan, assigned to interdict the Southside Railroad, met brigades commanded by George Pickett at the Five Forks junction, smashing them, taking thousands of prisoners, and encouraging General Grant to order a general advance. When the Union Sixth Corps broke through Confederate lines on Boydton Plank Road south of Petersburg, Confederate casualties exceeded 5000, or about a tenth of Lee's defending army. General Lee then informed Jefferson Davis that he was about to evacuate Richmond.

On what road did the US Army Sixth Corps shatter the Confederate line?
Output: Boydton Plank

Input: Szlachta
There were a number of avenues to upward social mobility and the achievement of nobility. Poland's nobility was not a rigidly exclusive, closed class. Many low-born individuals, including townsfolk, peasants and Jews, could and did rise to official ennoblement in Polish society. Each szlachcic had enormous influence over the country's politics, in some ways even greater than that enjoyed by the citizens of modern democratic countries. Between 1652 and 1791, any nobleman could nullify all the proceedings of a given sejm (Commonwealth parliament) or sejmik (Commonwealth local parliament) by exercising his individual right of liberum veto (Latin for "I do not allow"), except in the case of a confederated sejm or confederated sejmik.

WHo could nullify all the proceedings of a given sejm?
Output: any nobleman

Input: Gamal Abdel Nasser
In the 1950 parliamentary elections, the Wafd Party of el-Nahhas gained a victorymostly due to the absence of the Muslim Brotherhood, which boycotted the electionsand was perceived as a threat by the Free Officers as the Wafd had campaigned on demands similar to their own. Accusations of corruption against Wafd politicians began to surface, however, breeding an atmosphere of rumor and suspicion that consequently brought the Free Officers to the forefront of Egyptian politics. By then, the organization had expanded to around ninety members; according to Khaled Mohieddin, "nobody knew all of them and where they belonged in the hierarchy except Nasser". Nasser felt that the Free Officers were not ready to move against the government and, for nearly two years, he did little beyond officer recruitment and underground news bulletins.

How long did Nasser swell the ranks of his Free Officers?
Output: nearly two years

Input: Adult contemporary music
Soft rock reached its commercial peak in the mid-to-late 1970s with acts such as Toto, England Dan & John Ford Coley, Air Supply, Seals and Crofts, America and the reformed Fleetwood Mac, whose Rumours (1977) was the best-selling album of the decade. By 1977, some radio stations, like New York's WTFM and NBC-owned WYNY, had switched to an all-soft rock format. By the 1980s, tastes had changed and radio formats reflected this change, including musical artists such as Journey. Walter Sabo and his team at NBC brought in major personalities from the AM Band to the FM Band taking the format from a background to a foreground listening experience. The addition of major radio stars such as Dan Daniel, Steve O'Brien, Dick Summers, Don Bleu and Tom Parker made it possible to fully monetize the format and provide the foundation for financial success enjoyed to this day

What artist released the best selling album of the 1970s?

Fleetwood Mac
