Detailed Instructions: 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 Colombia, an American engineer named Harry Burck is overseeing the opening of his company's water pipeline. In the middle of the unveiling ceremony, a group of rebels arrives to kidnap an American diplomat who is in attendance. In the process, Harry is also kidnapped.
Word of the kidnapping reaches Harry's brother Corey and his friends Bob, Spence, and Kurt, who were all awaiting Harry's return. The men, coworkers at a factory, learn that Harry's kidnapping was orchestrated by a drug lord named Carlos Ochobar. Corey and Bob travel to Washington, D.C. to seek assistance from the U.S. government, only to be told that there are no plans to mount a rescue. Harry's father, Harry Burck, Sr., is despondent over the kidnapping of his son.
Kurt reminds his friends that they all personally owe Harry something, and that their only choice is to rescue him themselves. Despite some resistance and skepticism from Kurt and Spence, all the men eventually agree to go. Before heading to Colombia, they enlist the financial help of a sympathetic local car salesman, Jack, who insists on going along as a condition of funding the rescue, and the military expertise of a mercenary named Norman Shrike. Due to the urgency of the mission, Shrike is only able to give the group perfunctory training in military tactics.
Once in Colombia, the group encounters resistance, both from local officials and from the U.S. government. The group eventually lands in jail after being set up by one of Shrike's contacts who was going to supply them with weapons. They are handed over to U.S. officials and put on a plane back to the U.S. Just prior to takeoff, the group manages to escape, but Kurt decides to give up and go home.
A:
Where was the American diplomat in attendance when he was kidnapped?
