In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present. 
Question: Who played the keyboard with striking virtuosity?
[EX A]: Wolfgang.

[EX Q]: Passage: Between 9:00 pm and 10:00 pm the guards enacted a strategy whereby the police officers, backed by the bayonets of the soldiers, advanced to the crowd and arrested each a man, who was then taken into the station, disarmed, and held there. The strategy was largely successful, and by 11:00 pm the area around the station was mostly cleared, though sporadic gunfire could be heard throughout the night. Between 165 and 200 were detained in total, and the most violent of the captives were removed and taken to the police station. The news reported that four, including one police officer, were injured in the exchange, and several who resisted arrest were beaten severely.At the foundry near the Carey Street Bridge, a crowd of more than 100 gathered and threatened to set fire to the area. A contingent of the 5th under Captain Lipscomb arrived, and a volley fired over the heads of the crowd was sufficient to dissuade the crowd. An unsuccessful attempt was also made to burn a B&O transportation barge at Fell's Point. The news reported that 16 were arrested in a confrontation between citizens and the police at Lee and Eutaw, and that during the night, three separate attempts were made to set fire the 6th Regiment armory, but all were frustrated by the remaining garrison there.Just before midnight, 120–135 marines arrived at the station and reported to the governor, who ordered them to set about capturing the leaders of the mob. Governor Carroll telegraphed and advised President Hayes that order had been restored in the city.
Between 2:00 am and 3:00 am on Sunday morning, July 22, the peace was again broken and fire alarms began to ring throughout the city. To the west, at the Mount Clare Shops of the B&O, a 37-car train of coal and oil had been set on fire. Police, firefighters, and thousands of citizens flocked to the scene. A contingent of 50 marines was dispatched to the area to provide assistance. The cars which had not yet caught fire were detached from those burning, and by the time the flames were extinguished between seven and nine cars had been burned. Between $11,000 and $12,000 in damage was sustained.At 4:00 am another alarm sounded: the planing mills and lumber yard of J. Turner & Cate near the Philadelphia Wilmington & Baltimore rail depot, had been set on fire. The entire property, extending over a full city block, was destroyed. Realizing the severity of the situation, the firefighters concentrated their efforts on trying to save the surrounding structures.According to news reports, the first passenger trains left the city at 9:00 am, and continued running throughout the day. Around 10:00 am, General W. S. Hancock arrived and was followed by 360–400 federal troops from New York and Fort Monroe, who relieved those guarding Camden Station. They brought with them two 12 pounder artillery pieces. From that point on, the men of the 5th and the federal troops took turns guarding the station. 
Question: At what time was the lumber yard of J. Turner & Cate set on fire on the day where a car train of coal was set on fire?
[EX A]: 4:00 am.

[EX Q]: Passage: Desegregation in Birmingham took place slowly after the demonstrations. King and the SCLC were criticized by some for ending the campaign with promises that were too vague and "settling for a lot less than even moderate demands". In fact, Sydney Smyer, president of the Birmingham Chamber of Commerce, re-interpreted the terms of the agreement. Shuttlesworth and King had announced that desegregation would take place 90 days from May 15.  Smyer then said that a single black clerk hired 90 days from when the new city government took office would be sufficient. By July, most of the city's segregation ordinances had been overturned.  Some of the lunch counters in department stores complied with the new rules. City parks and golf courses were opened again to black and white citizens.  Mayor Boutwell appointed a biracial committee to discuss further changes.  However, no hiring of black clerks, police officers, and firefighters had yet been completed and the Birmingham Bar Association rejected membership by black attorneys.The reputation of Martin Luther King Jr. soared after the protests in Birmingham, and he was lauded by many as a hero. The SCLC was much in demand to effect change in many Southern cities. In the summer of 1963, King led the March on Washington for Jobs and Freedom where he delivered his most famous speech, "I Have a Dream".
King became Time's Man of the Year for 1963 and won the Nobel Peace Prize in 1964.
Four months after the Birmingham campaign settlement, someone bombed the house of NAACP attorney Arthur Shores, injuring his wife in the attack. On September 15, 1963, Birmingham again earned international attention when Ku Klux Klan members bombed the 16th Street Baptist Church on a Sunday morning and killed four young girls.  FBI informant Gary Thomas Rowe was hired to infiltrate the KKK and monitor their activities and plans. Rowe was involved, along with the Birmingham Police, with the KKK attacks on the Freedom Riders, led by Fred Shuttlesworth, in Anniston, Alabama on May 14, 1961. In addition, Rowe and several other Klansmen also partook in the killing of Civil Rights activist Viola Liuzzo on March 25, 1965, in Lowndes County, Georgia after the Selma to Montgomery march.The Birmingham campaign inspired the Civil Rights Movement in other parts of the South. Two days after King and Shuttlesworth announced the settlement in Birmingham, Medgar Evers of the NAACP in Jackson, Mississippi demanded a biracial committee to address concerns there. On June 12, 1963, Evers was fatally shot outside his home.  He had been organizing demonstrations similar to those in Birmingham to pressure Jackson's city government. In 1965 Shuttlesworth assisted Bevel, King, and the SCLC to lead the Selma to Montgomery marches, intended to increase voter registration among black citizens. 
Question: What is the first name of the person who had been organizing demonstrations similar to those in Birmingham to pressure Jackson's city government?
[EX A]:
Medgar.
