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: A few months before the D-Day landings during the Second World War, the British government decides to launch a campaign of disinformation; spreading a rumour that the landings just might take place at a location other than Normandy. The details of the operation (actually, there were several such operations) are handed to two intelligence officers, Colonel Logan and Major Harvey. They are initially unable to devise such a plan – but one night, Harvey sees an actor at a London theatre, putting on a convincing impression of General Bernard Montgomery.
Logan and Harvey discover that the actor is M. E. Clifton James (who plays himself in the film), a lieutenant stationed in Leicester with the Royal Army Pay Corps and that he was a professional actor in peacetime. He is called to London, on the pretext that he is to make a test for an army film, and a plan is devised that he should tour North Africa, impersonating 'Monty'.
'Jimmy' as Harvey calls him, is doubtful that he can carry off an impersonation of Montgomery, especially with his air of command, but with time running short and no options open to him, he agrees.
Disguised as a corporal, he spends some days at Montgomery's headquarters and learns to copy the general's mannerisms and style. After an interview with the general himself, he is sent off to tour North Africa.
Accompanied by Harvey, who has been 'promoted' to brigadier for his cover as Montgomery's aide-de-camp, 'Jimmy' arrives at Gibraltar, where the governor, who has known the general for years, can't get over the likeness. To further foster the deception, a local businessman and known German agent, Karl Nielson, is invited to dinner, knowing that he will spread the information. This happens quickly and their aeroplane is (unsuccessfully) attacked on leaving Gibraltar.
Solution:
What's the name of the operation that the Colonel and Major are given details to?
