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: For years, stories circulated of a treasure being buried within the amphitheater. W. T. McWhorter was determined to find out if it was true, so he planned to dynamite the amphitheater on the day he was to transfer the deed to the CoE. Spectators attended the planned explosion, but it was stopped just in time by CoE attorney David Waid.The dam was completed, and Beaver Lake was at full height by June 1966. For all intents and purposes, Harvey's Monte Ne was gone. However, in times of drought, some of the structures become visible again. The lake dropped to its lowest level on January 22, 1977, more than 27 feet (8 m) below its average depth, and the amphitheater and bridges were visible for the first time in more than 10 years. Before the water flooded downtown Monte Ne again, the rest of the buildings were either bulldozed or moved to avoid problems for swimmers, boaters, and fishermen. The few bridges that spanned the lagoon and the amphitheater were not demolished.In 2006, the waters of Beaver Lake once again receded to their lowest level since 1984, just above 1,100 feet (335 m). This generated a new brief interest in Monte Ne and people were once again attracted to the edge of the lake to explore the remains. The upper part of the amphitheater and the retaining wall built for the never constructed pyramid were exposed for a time before being once again swallowed by the lake.The flooded Monte Ne has become a site of interest for scuba divers who dive by the amphitheater to get a look at the submerged structure. The water is moderately clear and temperatures comfortable.
Solution:
What is the name of the lake that dropped to its lowest level on January 22, 1977?
