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: In the early 1960s, a three-girl "Greek chorus"—Crystal, Ronnette, and Chiffon—introduce the movie, warning the audience that some horror is coming their way ("Prologue: Little Shop of Horrors"). Seymour Krelborn and his colleague, Audrey, work at Mushnik's Flower Shop in a run-down, rough neighborhood in New York City referred to as "Skid Row". They lament that they cannot escape the neighborhood ("Skid Row (Downtown)"). Struggling from a lack of customers, Mr. Mushnik decides to close the store, but Audrey suggests he may have more success by displaying an unusual plant that Seymour owns. Immediately attracting a customer, Seymour explains he bought the plant, which he dubbed "Audrey II", from a Chinese flower shop during a solar eclipse. Attracting business to Mushnik's shop, the plant soon starts to wither. Seymour accidentally pricks his finger, and discovers that Audrey II needs human blood to thrive ("Grow for Me").
Solution:
Besides the owner, who else works in the store with the man that owns the unusual plant?
