Given the task definition, example input & output, solve the new input case.
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.
Example: 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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: On the Franco-Austrian Frontier during World War I, an Oriental priest, chaplain of a French colonial regiment, is condemned to life imprisonment because he possesses the power to turn men into zombies. In his prison cell, the priest prepares to burn a parchment containing the location of the secret formula. Gen. Mazovia kills the priest and takes the partially burned parchment. After the war, an expedition of representatives from the Allied countries with colonial interests are sent to Cambodia to find and destroy forever the so-called "Secret of the Zombies". The group includes Colonel Mazovia; a student of dead languages, Armand Louque; Englishman Clifford Grayson; General Duval; and his daughter Claire.
Armand falls in love with Claire, who accepts his proposal of marriage to spite Clifford, whom she really loves. Later, when Claire runs to Cliff for comfort following an accident, Armand breaks the engagement, leaving her free to marry Cliff. Further accidents caused by Mazovia result in the natives refusing to work, forcing the expedition to return to Phnom Penh. Armand finds a clue which he had overlooked before and returns to Angkor against orders.
After viewing an ancient ceremony at a temple, Armand follows one of the servants of a high priest out of the temple, through a swamp, to a mysterious bronze doorway. When the servant leaves, Armand goes through the door to a room paneled in bronze, with an idol holding a gong. He accidentally strikes the gong, and a panel in the wall opens, revealing a small metal tablet. He translates the inscription and realizes that it is the secret for which they have all been looking. He alone now has the power to make zombies out of people, and begins with a practice run on his servant before using his zombie powers in an attempt to coerce the fickle Claire in the movie's climax.
Output:
Which person finds the "Secret of the Zombies"?
