Detailed 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.
Q: Passage: Shoshone National Forest receives an average of over half a million visitors a year. Two visitor centers provide orientation, books, maps, and interpretive displays. One visitor center is at the Wapiti Wayside on the Buffalo Bill Cody Scenic Byway, west of Cody, Wyoming and adjacent to the historic Wapiti Ranger Station while the other visitor center is to the south in Lander, Wyoming. There are 30 vehicle access campgrounds in the forest, with up to 54 individual sites per campground. Approximately half of these campgrounds provide running water and restroom facilities and also provide for handicapped accessibility. Referred to as "front country" campgrounds, they also permit recreational vehicle access in most cases. All of the campgrounds are on a first come, first served basis although four campgrounds have sites that can be reserved in advance by contacting the National Reservation Service. Due to the presence of grizzly bears, a few of the campgrounds require what is referred to as "hard-sided" camping only, and tent camping is not permitted.
For some visitors the greater solitude of the backcountry requires using  hiking trails to backpacking or horseback riding into more remote destinations such as Blackwater Natural Bridge which can be accessed from Blackwater Natural Bridge trailhead. There are dozens of trails which total over 1,600 mi (2,600 km) located throughout the forest. Many of the trailheads can be accessed at campgrounds, with shorter day hikes available as well. The Continental Divide Trail has a 20-mile (32 km) section which passes through the forest and crosses the Continental Divide at Sheridan Pass. There is also the Nez Perce National Historic Trail and the Beartooth Loop National Recreation Trail, both of which are in the northern regions of the forest. Some remote areas can also be accessed by horseback. Trailheads usually provide enough room for horse and pack animal trailers plus personal vehicles. Along forest access roads, all-terrain vehicles (ATV) are allowed, but since wilderness areas do not permit access by way of motorized transport, those who wish to visit such areas usually do so either by hiking in or on horseback.
