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: The gang is driving through a desert in Roswell, New Mexico when a sandstorm forces Shaggy to make a wrong turn onto government property. Soon after, a UFO causes Shaggy to crash the car, and the gang find themselves on the outskirts of a small town. While Scooby and Shaggy stay with the van, Fred, Daphne, and Velma go to a local diner to ask for directions. Shaggy and Scooby then see a mythical animal called a jackalope , which takes their last Scooby Snack. Scooby and Shaggy chase the jackalope into a cave, where they encounter aliens. They flee the cave and run into the diner in a panic.
Scooby and Shaggy tell the people inside the diner about their encounter, but the gang is skeptical. The waitress, Dottie, says that multiple people claimed to have seen aliens, but that she has never seen them, but she has noticed strange lights and sounds at night. The chef, Sergio, says that a month earlier local cattle vanished without a trace, after which many people left town. A man named Lester, who claims to have been abducted, believes Scooby and Shaggy. He also claims to have pictures from his abduction; however, they turn out to be nothing more than paintings. He then tells the gang that ever since the installation of SALF (Search for Alien Life Forms, similar to SETI) satellite dishes, there have been numerous reports of UFO sightings and disappearing livestock.
Solution:
Who runs out of a cave and into a diner after seeing aliens?
