Task: Question Generation
Input (English): Passage: At 09:30 on 2 May, Oan appeared at the first-floor window of the embassy to demand access to the telex system, which the police had disabled along with the telephone lines, and threatened to kill Abdul Fazi Ezzati, the cultural attaché. The police refused and Oan pushed Ezzati, who he had been holding at gunpoint at the window, across the room, before demanding to speak to somebody from the BBC who knew Sim Harris. The police, relieved to have a demand to which they could easily agree, produced Tony Crabb, managing director of BBC Television News and Harris's boss. Oan shouted his demands; for safe passage out of the UK, to be negotiated by three ambassadors from Arab countries, to Crabb from the first-floor window, and instructed that they should be broadcast along with a statement of the hostage-takers' aims by the BBC. The Foreign and Commonwealth Office informally approached the embassies of Algeria, Jordan, Kuwait, Lebanon, Syria and Qatar to ask if their ambassadors would be willing to talk to the hostage-takers. The Jordanian ambassador immediately refused and the other five said they would consult their governments. The BBC broadcast the statement that evening, but in a form unsatisfactory to Oan, who considered it to be truncated and incorrect.Meanwhile, the police located the embassy caretaker and took him to their forward headquarters to brief the SAS and senior police officers. He informed them that the embassy's front door was reinforced by a steel security door, and that the windows on the ground floor and first floor were fitted with armoured glass, the result of recommendations made after the SAS had been asked to review security arrangements for the embassy several years earlier. Plans for entering the embassy by battering the front door and ground-floor windows were quickly scrapped and work began on other ideas.
Output (English): What is the last name of the person who demanded to speak to somebody from the BBC?
