Instructions: 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.
Input: Passage: According to John Young, "As soon as you enter Worlds End State Park, you hear it: the never-ending rush of the waters of Loyalsock Creek". The creek and its tributary Double Run have been designated as approved trout waters within the park by the Pennsylvania Fish and Boat Commission. This means the waters will be stocked with trout and may be fished during trout season. Hunting is permitted on about half of the lands of Worlds End State Park. Hunters are expected to follow the rules and regulations of the Pennsylvania Game Commission. The common game species are ruffed grouse, eastern gray squirrels, turkey, white-tailed deer and bears; however, the hunting of groundhogs is prohibited.Edward Gertler, author of Keystone Canoeing, writes that Loyalsock Creek's "exciting whitewater, above Forksville, has long been a favorite of paddlers who are quick and tolerant enough to endure its fickle water levels and weather". This is the stretch of the creek in and near the park, whose "long, steepening, and complex boulder patch and ledgy rapids demand your attention ... A boater's chute through the middle of the swimming area dam at Worlds End State Park climaxes this run".The best time for whitewater boating on Loyalsock Creek at Worlds End State Park is from March to May, and the park hosts a slalom race on Loyalsock Creek each spring. The whitewater gradient is 41 for the section of the creek in and near the park, and its rating on the International Scale of River Difficulty is II to III+, with sections reaching IV. The water is too swift for open canoes, so visitors are asked to use kayaks. The swimming area is closed to whitewater boating during the summer months.
Output:
What are the names of the waterways that have been designated as approved trout waters within the park by Pennsylvania Fish and Boat Commission?
