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: 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.
