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: It is Halloween in the small town of Pitchford Cove located somewhere in New England, and five high school friends, Phil, Mary, Mitch, Vinnie, and Melissa, plan on making it a night they will never forget. They steal outfits from the town's historic museum and come upon other old artifacts, including an old trunk encasing a paper scroll which contains an ancient curse. When Melissa, latent sorceress, recites the curse at the local cemetery, things take a turn for the worse.
The town's dead, led by Melissa's great-great-great-great-grandmother Lucinda Cavender, a witch who was put to death 300 years earlier, rise up from their graves and roam the town. As Melissa, Vinnie, Mitch, and Mary enjoy themselves at their annual Halloween costume party, Phil encounters a mysterious girl, named Sandra "Sandy" Matthews, dressed in a vintage 1950's cheerleader outfit, who warns him that the whole town is in danger.
Meanwhile, Lucinda and the various undead crash the costume party. At first, nobody pays much attention to them since everyone is in costume. However, Lucinda begins turning the party guests into vampires, starting with her great-great-great-great-granddaughter Melissa.
When Sandy discovers that Phil and his friends recited the ancient spell in the cemetery, they realize that the whole town is being overrun by the living dead and decide to team up to break the curse. The only way to do so is to find the Grenville Spirit Ring inside the grave of a witch-hunter Nathaniel Grenville - who, coincidentally, was Phil's great-great-great-great-grandfather and slave owner of Lucinda Cavender, her arch-nemesis - and use it to undo the curse.  Phil and "good ghost" Sandy must restore the town to normal by midnight before it is too late and the curse becomes permanent.
Solution:
What is the last name of the person who crashes the party with other undead?
