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.
One example is below.
Q: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
A: Who believes Fagin's gang make wallets and handkerchiefs?.
Rationale: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: Oan, angered by the BBC's incorrect reporting of his demands the previous evening, contacted the police negotiators shortly after 06:00 and accused the authorities of deceiving him. He demanded to speak with an Arab ambassador, but the negotiator on duty claimed that talks were still being arranged by the Foreign Office. Recognising the delaying tactic, Oan told the negotiator that the British hostages would be the last to be released because of the British authorities' deceit. He added that a hostage would be killed unless Tony Crabb was brought back to the embassy. Crabb did not arrive at the embassy until 15:30, nearly ten hours after Oan demanded his presence, to the frustration of both Oan and Sim Harris. Oan then relayed another statement to Crabb via Mustapha Karkouti, a journalist also being held hostage in the embassy. The police guaranteed that the statement would be broadcast on the BBC's next news bulletin, in exchange for the release of two hostages. The hostages decided amongst themselves that the two to be released would be Hiyech Kanji and Ali-Guil Ghanzafar; the former as she was pregnant and the latter for no other reason than his loud snoring, which kept the other hostages awake at night and irritated the terrorists.Later in the evening, at approximately 23:00, an SAS team reconnoitred the roof of the embassy. They discovered a skylight, and succeeded in unlocking it for potential use as an access point, should they later be required to storm the building. They also attached ropes to the chimneys to allow soldiers to abseil down the building and gain access through the windows if necessary.
A:
Who attached ropes to the chimneys to allow soldiers to abseil down the building?
