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.

Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.
Who finds the shipping magnate's opera tickets?

Passage: Santa Anna had successfully escaped towards Vince's Bridge.  Finding the bridge destroyed, he hid in the marsh and was captured the following day. He was brought before Houston, who had been shot in the ankle and badly wounded. Texian soldiers gathered around, calling for the Mexican general's immediate execution.  Bargaining for his life, Santa Anna suggested that he order the remaining Mexican troops to stay away.  In a letter to Filisola, who was now the senior Mexican official in Texas, Santa Anna wrote that "yesterday evening [we] had an unfortunate encounter" and ordered his troops to retreat to Béxar and await further instructions.Urrea urged Filisola to continue the campaign.  He was confident that he could successfully challenge the Texian troops.  According to Hardin, "Santa Anna had presented Mexico with one military disaster; Filisola did not wish to risk another."  Spring rains ruined the ammunition and rendered the roads almost impassable, with troops sinking to their knees in mud.  Mexican troops were soon out of food, and began to fall ill from dysentery and other diseases.  Their supply lines had completely broken down, leaving no hope of further reinforcements. Filisola later wrote that "Had the enemy met us under these cruel circumstances, on the only road that was left, no alternative remained but to die or surrender at discretion".For several weeks after San Jacinto, Santa Anna continued to negotiate with Houston, Rusk, and then Burnet.  Santa Anna suggested two treaties, a public version of promises made between the two countries, and a private version that included Santa Anna's personal agreements.  The Treaties of Velasco required that all Mexican troops retreat south of the Rio Grande and that all private property—code for slaves—be respected and restored.  Prisoners-of-war would be released unharmed, and Santa Anna would be given passage to Veracruz immediately.  He secretly promised to persuade the Mexican Congress to acknowledge the Republic of Texas and to recognize the Rio Grande as the border between the two countries.When Urrea began marching south in mid-May, many families from San Patricio who had supported the Mexican army went with him.  When Texian troops arrived in early June, they found only 20 families remaining.  The area around San Patricio and Refugio suffered a "noticeable depopulation" in the Republic of Texas years.  Although the treaty had specified that Urrea and Filisola would return any slaves their armies had sheltered, Urrea refused to comply. Many former slaves followed the army to Mexico, where they could be free.  By late May the Mexican troops had crossed the Nueces.  Filisola fully expected that the defeat was temporary and that a second campaign would be launched to retake Texas.
What is the name of the person who secretly promised to persuade the Mexican Congress to acknowledge the Republic of Texas and to recognize the Rio Grande as the border between the two countries?

Passage: At 9:45 am, Governor Frank Keating declared a state of emergency and ordered all non-essential workers in the Oklahoma City area to be released from their duties for their safety. President Bill Clinton learned about the bombing at around 9:30 a.m. while he was meeting with Turkish Prime Minister Tansu Çiller at the White House. Before addressing the nation, President Clinton considered grounding all planes in the Oklahoma City area to prevent the bombers from escaping by air, but decided against it. At 4:00 pm, President Clinton declared a federal emergency in Oklahoma City and spoke to the nation:
The bombing in Oklahoma City was an attack on innocent children and defenseless citizens. It was an act of cowardice and it was evil. The United States will not tolerate it, and I will not allow the people of this country to be intimidated by evil cowards.
He ordered that flags for all federal buildings be flown at half-staff for 30 days in remembrance of the victims. Four days later, on April 23, 1995, Clinton spoke from Oklahoma City.No major federal financial assistance was made available to the survivors of the Oklahoma City bombing, but the Murrah Fund set up in the wake of the bombing attracted over $300,000 in federal grants. Over $40 million was donated to the city to aid disaster relief and to compensate the victims. Funds were initially distributed to families who needed it to get back on their feet, and the rest was held in trust for longer-term medical and psychological needs. By 2005, $18 million of the donations remained, some of which was earmarked to provide a college education for each of the 219 children who lost one or both parents in the bombing. A committee chaired by Daniel Kurtenbach of Goodwill Industries provided financial assistance to the survivors.

What is the full name of the person who  met a Prime Minister at the White House?
