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: Oswald and a big beagle are at a cinema watching a documentary. The documentary tells about explorers who travel place to place in their hot air balloons. Oswald is amazed by the adventures of the explorers, and therefore decides become an explorer too.
One day at a fairground, a large crowd gathers to see Oswald take off in his balloon. The balloon is a large hot water bottle and the carriage is a metal stove (with switches inside). Oswald invites the big beagle, who is in the crowd, to join him.
The big beagle, at first, declines the invitation before he shakes hands with his little friend, and releases the balloon. But as the balloon rises and one of its anchors snags away his pants, the big beagle changes his mind. He would spend the entire ride on the anchor.
Oswald's balloon rapidly ascend into the heavens. They go so fast and so high that they even reach space. Their voyage ends when they land on the planet Mars. Unfortunately for them, their balloon is wreck, and the two are left wondering if they would ever get back. They begin walking on the rocky Martian surface. On the way, they see a giant sipping soup and gobbling explosives. Because of the giant's hostile nature, Oswald and the big beagle try to flee, only to unknowingly run into the bore of a huge cannon. The cannon shoots them airborne and they land in the giant's soup bowl.
The giant is surprised to see the two visitors in his bowl. Nevertheless, he becomes obliged to gobble them as he scoops up Oswald and the big beagle with his spoon. Suddenly the giant decides to delay eating his victims. He then puts Oswald and the big beagle in a large salt shaker and then chooses to have some music played by walking guns.
Solution:
Where did Oswald and a big beagle land when they were shot out of a canon?
