Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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?.
Reason: 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.

Now, solve this instance: Passage: Kitchen Creek flows through the park's three glens, which the descriptions of the waterfalls are organized by: Ricketts Glen, Glen Leigh, and Ganoga Glen. The falls are listed in order going upstream along Kitchen Creek, starting with the southernmost and ending at the northernmost in each glen. This is also the order in which a hiker would encounter the falls while traveling north along the creek on the Falls Trail.The Falls Trail is a 7.1-mile (11.4 km) loop hike. Starting at PA 118, it is 1.8 miles (2.9 km) north along the creek through Ricketts Glen to Waters Meet, where the trail divides. Following the Glen Leigh branch, it is 1.2 miles (1.9 km) north through the glen to the Highland Trail, then 1.0 mile (1.6 km) west along the Highland Trail to Ganoga Glen. Turning southeast, it is 1.3 miles (2.1 km) through Ganoga Glen back to Waters Meet, then the 1.8 miles (2.9 km) through Ricketts Glen is retraced, but heading south back to PA 118.The description of each waterfall starts with the name. While the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of State Parks names 22 waterfalls in Ricketts Glen State Park (all but Kitchen Creek and Shingle Cabin), the United States Geological Survey (USGS) Geographic Names Information System (GNIS) names 23 (all but Shingle Cabin), and Scott E. Brown's 2004 book Pennsylvania waterfalls: a guide for hikers and photographers names 24. There are also several unnamed waterfalls in the park, with the total number of falls given as 33 or 34. For each waterfall the height is given next, followed by the elevation above sea level, and the latitude and longitude. Each waterfall in the table is classified according to the four types used in Brown's book (falls, cascade, slide, and chute), with some classified as combinations of types. For each waterfall there are notes, which can give more information on the waterfall, the etymology of the name, and the location on the Falls Trail, followed by a photograph.
Student:
What is the full name for the DCNR?
