In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Q: Passage: In 1870, 18-year-old Travis Coates is left in charge of his precocious 12-year-old brother, Arliss, on the family farm in Southwest Texas, while their parents visit an ailing grandmother. While Arliss and his dog, Savage Sam, are tracking a bobcat, Travis is warned by Bud Searcy that renegade Apaches are in the area. When Travis joins Bud's 17-year-old daughter, Lisbeth, in a search for Arliss, all three are captured by a band of Apaches led by a Comanche. The boys' Uncle Beck Coates witnesses the scene and manages to wound the Native American leader, but Beck's horse is shot by one of the braves, allowing the Comanche and his followers to escape with the captives. Beck alerts the U. S. Cavalry, but the Native Americans split into three groups and ride for the hills; in the confusion, Travis escapes but is knocked unconscious and left to die. Beck and his posse of five find Travis and his dog, set out in pursuit of the other captives, and eventually find the Indians in a valley fighting over Lisbeth. Although posse member Pack Underwood, bent on revenge for the massacre of his family, fires a shot that alerts the Indians to their planned ambush, the youngsters are saved and the renegades captured.

Q: Passage: The management of Rockefeller Center shifted around this time. In November 1936, John Todd was featured in two New Yorker articles that emphasized his role in the complex's construction. At the same time, Nelson was gaining clout within Rockefeller Center Inc., and he disagreed with nearly all of Todd's suggestions. Nelson's father, John, was relinquishing his responsibilities, since the Rockefeller family's youngest son David had moved out of the family home at 10 West 54th Street, and John was now focusing on his own personal life. By April 1937, Todd regretted his decision to be featured in The New Yorker. In March 1938, Nelson became the president of Rockefeller Center Inc. He then fired Todd as the complex's manager and appointed Hugh Robertson in his place. Nelson and Robertson wanted to avoid workers' strikes, which would delay the completion of construction. Nelson, Robertson, and the workers' unions agreed to a contract in which the unions would not strike, Robertson would not lock out union workers, and both would agree to arbitration if a labor dispute arose. Rockefeller Center was one of Nelson's primary business ventures until 1958, when he was elected Governor of New York.Public relations officials were hired to advertise the different parts of the complex, such as the gardens and the plaza. Merle Crowell set up a viewing platform on the east side of Rockefeller Center and founded the facetious "Sidewalk Superintendents' Club" so the public could view construction.

A: What is the first name of the person who appointed Hugh Robertson as the complex manager?

Q: Passage: In a troop movement that took all night on a makeshift raft, the Texian army crossed Buffalo Bayou at Lynchburg April 19 with 930 soldiers, leaving behind 255 others as guards or for reasons of illness. The idea had been floated of leaving the Twin Sisters behind as protection, but Neill was adamant that the cannons be taken into the battle. In an April 20 skirmish the day before the main battle Neill was severely wounded, and George Hockley took command of the heavy artillery. Estimates of the Mexican army troop strength on the day of the main battle range from 1,250 to 1,500.The Texians attacked in the afternoon of April 21 while Santa Anna was still under the misconception that Houston was actually retreating. He had allowed his army time to relax and feed their horses, while he took a nap. When he was awakened by the attack, he immediately fled on horseback, but was later captured when Sergeant James Austin Sylvester found him hiding in the grass. Houston's own account was that the battle lasted "about eighteen minutes", before apprehending prisoners and confiscating armaments. When the Twin Sisters went up against the Mexican army's Golden Standard cannon, they performed so well that Hockley's unit was able to capture the Mexican cannon.The Yellowstone saw war service for the Republic one more time on May 7, when it transported Houston and his prisoner Santa Anna, along with the government Santa Anna tried to extinguish, to Galveston Island. From there, the government and Santa Anna traveled to Velasco for the signing of the treaties. Houston had suffered a serious wound during the battle, and on May 28 boarded the schooner Flora for medical treatment in New Orleans.Not until news of the victory at San Jacinto spread did the refugees return to their homesteads and businesses, or whatever was left after the destruction caused by both armies. Throughout Texas, possessions had been abandoned and later looted. Businesses, homes and farms were wiped out by the devastation of war. Often there was nothing left to go back to, but those who went home began to pick up their lives and move forward. San Felipe de Austin never really recovered from its total destruction. The few people who returned there moved elsewhere, sooner or later. Secretary of War Rusk would later commend the women of Texas who held their families together during the flight, while their men volunteered to fight: "The men of Texas deserve much credit, but more was due the women. Armed men facing a foe could not but be brave; but the women, with their little children around them, without means of defense or power to resist, faced danger and death with unflinching courage.".

A:
What is the first name of the person whose unit was able to capture the Mexican cannon?
