You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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: 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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? 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.

New input: Passage: On March 19, 2003, Iraqi General Mohammed Al-Rawi flees his residence amid the bombardment of Baghdad. Before leaving the compound, he passes a notebook to his aide Seyyed, instructing him to warn his officers to get to their safehouses and wait for his signal.
Four weeks later, U.S. Army Chief Warrant Officer Roy Miller and his platoon check a warehouse for Iraqi weapons of mass destruction. To Miller's surprise, the warehouse has not been secured, with looters making their way in and out, as soldiers from the 101st Airborne Division are too few to do much. After a firefight with a sniper, Miller finds that the warehouse is empty, the third consecutive time an official mission has led to a dead end. Later, at a debriefing, Miller brings up the point that the majority of the intel given to him is inaccurate and anonymous. High-ranking officials quickly dismiss his concerns. Afterward, CIA agent Martin Brown tells him that the next place he is to search was inspected by a UN team two months prior and that it too has been confirmed empty.
Meanwhile, U.S. Department of Defense official Clark Poundstone welcomes returning Iraqi exile politician Ahmed Zubaidi at the airport. There Poundstone is questioned by Wall Street Journal reporter Lawrie Dayne. She says she needs to speak directly to "Magellan", but Poundstone brushes her off.
Solution:
What is the rank of the person whose signal Seyyed must wait for?
