instruction:
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.
question:
Passage: Most historians describe the contacts between the Mongol Empire and the Western Europeans as a series of attempts, missed opportunities, and failed negotiations. Christopher Atwood, in the 2004 Encyclopedia of Mongolia and the Mongol Empire, summed up the relations between Western Europe and the Mongols: "Despite numerous envoys and the obvious logic of an alliance against mutual enemies, the papacy and the Crusaders never achieved the often-proposed alliance against Islam."A few other historians argue there was an actual alliance, but do not agree on the details: Jean Richard wrote that an alliance began around 1263. Reuven Amitai stated that the closest thing to actual Mongol-Frankish military coordination was when Prince Edward of England attempted to coordinate activities with Abaga in 1271. Amitai also mentioned the other attempts towards cooperation, but said, "In none of these episodes, however, can we speak of Mongols and troops from the Frankish West being on the Syrian mainland at the same time." Timothy May described the alliance as having its peak at the Council of Lyon in 1274, but that it began to unravel in 1275 with the death of Bohemond, and May too admitted that the forces never engaged in joint operations. Alain Demurger, in his own book The Last Templar, said that an alliance was not sealed until 1300.There also continues to be debate about whether or not an alliance would have been a wise idea, and whether the Crusaders at that point in history were even relevant to the Persian-Mongol conflict. The 20th-century historian Glenn Burger said, "The refusal of the Latin Christian states in the area to follow Hethum's example and adapt to changing conditions by allying themselves with the new Mongol empire must stand as one of the saddest of the many failures of Outremer." This was similar to the view of Steven Runciman, who argued, "Had the Mongol alliance been achieved and honestly implemented by the West, the existence of Outremer would almost certainly have been prolonged. The Mameluks would have been crippled if not destroyed; and the Ilkhanate of Persia would have survived as a power friendly to the Christians and the West". However, David Nicolle, describing the Mongols as "potential allies", said that early historians were writing from the benefit of hindsight, and that overall the major players were the Mamluks and the Mongols, with Christians just "pawns in a greater game.".
answer:
Who did Jean Richard claim had an alliance around 1263?


question:
Passage: Worlds End State Park is a 780-acre (316 ha) Pennsylvania state park in Sullivan County, Pennsylvania, in the United States. The park, nearly surrounded by Loyalsock State Forest, is in the Loyalsock Creek valley on Pennsylvania Route 154, in Forks and Shrewsbury Townships southeast of the borough of Forksville. The name Worlds End has been used since at least 1872, but its origins are uncertain. Although it was founded as Worlds End State Forest Park by Governor Gifford Pinchot in 1932, the park was officially known as Whirls End State Forest Park from 1936 to 1943.The park's land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills. The second growth forests in and surrounding Worlds End State Park are partially a result of the efforts of the young men of the Civilian Conservation Corps during the Great Depression. They helped overcome the clearcutting of the early 20th century, and built many of the park's facilities, including the cabins that earned it a place on the National Register of Historic Places.
A wide variety of wildlife is found in the park, which is also part of an Important Bird Area. Located in the Endless Mountains region of the dissected Allegheny Plateau, Worlds End has a continental climate and rocks and fossils from the Carboniferous period. It is one of "Twenty Must-See Pennsylvania State Parks" named by the Pennsylvania Department of Conservation and Natural Resources, which describes it as "[v]irtually in a class by itself, this wild, rugged and rustic area seems almost untamed". The park offers year-round recreational opportunities, including environmental education, hiking, camping in tents and cabins, whitewater rafting, swimming, cross-country skiing, snowmobiling, hunting, and fishing.
answer:
What is the precise modern-day name of the park whose land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills?


question:
Passage: The Rogue River begins at Boundary Springs on the border between Klamath and Douglas counties near the northern edge of Crater Lake National Park. Although it changes direction many times, it flows generally west for 215 miles (346 km) from the Cascade Range through the Rogue River – Siskiyou National Forest and the Klamath Mountains to the Pacific Ocean at Gold Beach. Communities along its course include Union Creek, Prospect, Trail, Shady Cove, Gold Hill and Rogue River, all in Jackson County; Grants Pass and Galice in Josephine County; and Agness, Wedderburn and Gold Beach in Curry County. Significant tributaries include the South Fork Rogue River, Elk Creek, Bear Creek, the Applegate River, and the Illinois River. Arising at 5,320 feet (1,622 m) above sea level, the river loses more than 1 mile (1.6 km) in elevation by the time it reaches the Pacific.
It was one of the original eight rivers named in the National Wild and Scenic Rivers Act of 1968, which included 84 miles (135 km) of the Rogue, from 7 miles (11.3 km) west of Grants Pass to 11 miles (18 km) east of the mouth at Gold Beach. In 1988, an additional 40 miles (64 km) of the Rogue between Crater Lake National Park and the unincorporated community of Prospect was named Wild and Scenic. Of the river's total length, 124 miles (200 km), about 58 percent is Wild and Scenic. The Rogue is one of only three rivers that start in or east of the Cascade Range in Oregon and reach the Pacific Ocean. The others are the Umpqua River and Klamath River. These three Southern Oregon rivers drain mountains south of the Willamette Valley; the Willamette River and its tributaries drain north along the Willamette Valley into the Columbia River, which starts in British Columbia rather than Oregon.
answer:

How many miles of the Rogue River are Wild and Scenic?
