[EX Q]: Passage: In Depression-era North Carolina, George Pemberton is an ambitious timber baron who meets Serena Shaw, a young woman with a sad past. He falls in love with her, they marry, and Serena comes with George to his land. There, she starts taking control of things, pressuring and questioning George, while remaining affectionate towards him.
George's business partner Buchanan feels threatened by her, as she begins to exceed his authority. Things grow worse between George and Buchanan, and Buchanan strikes a deal with the local sheriff, who wants to buy George's land to make a park. George is hurt by Buchanan's betrayal, and Serena convinces George that Buchanan was never his friend.
The next day, they both go shooting alone from the group attempting to flush out a bear. After some snide remarks from Buchanan, George contemplates killing him only to hesitate and be seen by Buchanan. As Buchanan cocks his rifle, George fires first and shoots him in the chest. Campbell, George's worker, witnesses the murder, but denies it when Sheriff McDowell inquires. The death is ruled an accident. Serena consoles George and justifies his actions.
One day, he sees his illegitimate son, Jacob, posing with his mother, Rachel, for a picture. He feels responsible for the boy, and since Rachel never asked for anything, he begins giving sums of money in envelopes to her for Jacob. Serena remains unaware of this, though she does consider Rachel and the baby a threat.
One day, an accident occurs in the forest and Galloway, a mysterious worker, loses his hand to an axe swing. Serena rushes to help him and uses a belt as a tourniquet to stop the bleeding which saves his life. Having problems with her pregnancy, Serena and George rush to the hospital after Serena experiences heavy bleeding and pain. She miscarries. They learn that she can never again bear children. Things continue to grow worse, and Rachel's baby becomes more obvious to Serena. 
Question: Whose death is ruled an accident?
[EX A]: Buchanan.

[EX Q]: Passage: The search for a singer-actress to play Carmen began in the summer of 1873. Press speculation favoured Zulma Bouffar, who was perhaps the librettists' preferred choice. She had sung leading roles in many of Offenbach's operas, but she was unacceptable to Bizet and was turned down by du Locle as unsuitable. In September an approach was made to Marie Roze, well known for previous triumphs at the Opéra-Comique, the Opéra and in London. She refused the part when she learned that she would be required to die on stage. The role was then offered to Célestine Galli-Marié, who agreed to terms with du Locle after several months' negotiation. Galli-Marié, a demanding and at times tempestuous performer, would prove a staunch ally of Bizet, often supporting his resistance to demands from the management that the work should be toned down. At the time it was generally believed that she and the composer were conducting a love affair during the months of rehearsal.The leading tenor part of Don José was given to Paul Lhérie, a rising star of the Opéra-Comique who had recently appeared in works by Massenet and Delibes. He would later become a baritone, and in 1887 sang the role of Zurga in the Covent Garden premiere of Les pêcheurs de perles. Jacques Bouhy, engaged to sing Escamillo, was a young Belgian-born baritone who had already appeared in demanding roles such as Méphistophélès in Gounod's Faust and as Mozart's Figaro. Marguerite Chapuy, who sang Micaëla, was at the beginning of a short career in which she was briefly a star at London's Theatre Royal, Drury Lane; the impresario James H. Mapleson thought her "one of the most charming vocalists it has been my pleasure to know". However, she married and left the stage altogether in 1876, refusing Mapleson's considerable cash inducements to return. 
Question: What is the full name of the person who Mapleson thought to be "one of the most charming vocalists" it had ever been his pleasure to know?
[EX A]: Marguerite Chapuy.

[EX Q]: Passage: The Pennsylvania State Capitol houses the chambers for the Pennsylvania House of Representatives, the Pennsylvania Senate, and the Harrisburg chambers for the Supreme Court of Pennsylvania. The Capitol contains 475 rooms and has four floors, not including a mezzanine between the first and second floors, and a basement.  The bronze entrance doors of the capitol lead into the rotunda on the first floor with the grand staircase in the center. The staircase in the rotunda is an imperial staircase, similar to the one in the Palais Garnier in Paris, France. The staircase leads to the mezzanine between the first and second floors, before dividing into two staircases leading to the second floor. Edwin Austin Abbey painted four allegorical medallions around the base of the capitol dome, detailing the "four forces of civilization": Art, Justice, Science, and Religion. Four lunette murals were also painted by Abbey and "symbolize Pennsylvania's spiritual and industrial contributions to modern civilization". The lunettes are situated in the recesses of each arch in the rotunda. The rotunda is paved with tiles, hand-crafted by Henry Chapman Mercer, from the Moravian Pottery and Tile Works. Mercer produced 16,000 square feet (1,500 m2) of tile, which includes "377 mosaics, representing 254 scenes, artifacts, animals, birds, fish, insects, industries and workers from Pennsylvania history". The interiors of the rotunda and the dome are inscribed with a quote from William Penn made upon the foundation of the Commonwealth of Pennsylvania:
There may be room there for such a holy experiment. For the nations want a precedent. And my God will make it the seed of a nation. That an example may be set up to the nations. That we may do the thing that is truly wise and just. 
Question: What was the last name of the person who handcrafted the tiles that paved the rotunda?
[EX A]:
Mercer.
