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: A Late Preclassic tomb has been excavated, believed to be a royal burial. This tomb has been designated Burial 1; it was found during excavations of Structure 7A and was inserted into the centre of this Middle Preclassic structure. The burial is also associated with Stela 13 and with a massive offering of more than 600 ceramic vessels and other artifacts found at the base of Structure 7A. These ceramics date the offering to the end of the Late Preclassic. No human remains have been recovered but the find is assumed to be a burial due to the associated artifacts. The body is believed to have been interred upon a litter measuring 1 by 2 metres (3.3 by 6.6 ft), which was probably made of wood and coated in red cinnabar dust. Grave goods include an 18-piece jade necklace, two earspools coated in cinnabar, various mosaic mirrors made from iron pyrite, one consisting of more than 800 pieces, a jade mosaic mask, two prismatic obsidian blades, a finely carved greenstone fish, various beads that presumably formed jewellery such as bracelets and a selection of ceramics that date the tomb to AD 100–200.In October 2012, a tomb carbon-dated between 700 BC and 400 BC was reported to have been found in Takalik Abaj of a ruler nicknamed K'utz Chman ("Grandfather Vulture" in Mam) by archaeologists, a sacred king or "big chief" who "bridged the gap between the Olmec and Mayan cultures in Central America," according to Miguel Orrego. The tomb is suggested to be the oldest Maya royal burial to have been discovered so far.
Solution:
What is associated with Stela 13?
