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 input: 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.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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: At Middlebury College in 1969, four young friends, Annie MacDuggan, Elise Elliot, Brenda Morelli, and Cynthia Swann, are graduating. Excited for the future and the potential it holds, the girls enthusiastically make a champagne toast celebrating their graduation as well as their friendship. As graduation gifts, valedictorian Cynthia presents the girls with matching Bulgari pearl necklaces. As the graduates take a commemorative picture of the four of them (presumably for the last time), Cynthia makes Annie, Brenda and Elise promise that they will always be there for each other throughout the remainder of their lives.
In the present time, the four friends eventually lose touch with one another, as evident when Cynthia is tearfully gazing at the picture of the four of them on that graduation day. Now wealthy and living in a luxurious penthouse, she gives her maid her own Bulgari pearl necklace (matching the three she gave to her friends on graduation day), and has the maid mail letters to them. She later walks outside on the balcony of her penthouse in a floor length fur coat, a cigarette and a drink, and then commits suicide by jumping to her death after learning through the tabloids that her ex-husband Gil (whom Cynthia made wealthy through her connections, according to narrator Annie) married his much younger mistress the day before.
A:
What is the last name of the person who gives out Bulgari pearl necklaces?
