question:
Passage: Cowboy drifter Jim Garry is summoned by his friend, smooth-talking Tate Riling. Garry rides into an Indian reservation and finds himself in the middle of a conflict between a cattle owner and some homesteaders. He meets cattle owner John Lufton, and eventually his daughters Amy and Carol. The Luftons suspect that Garry is on Riling's side and are initially hostile, especially Amy. Garry readily admits that he is going to work for his friend.
Riling tells Garry that he and Indian agent Jake Pindalest have devised an elaborate scheme to force Lufton into selling his herd cheaply. Pindalest has gotten the government to order Lufton to remove his cattle from the reservation in a week. Meanwhile, Riling has organized the homesteaders into blocking the move, conning them into believing that he is working in their best interests. With no other option, Lufton would have to sell his herd at bargain prices or lose everything. Lufton would never sell to Riling, but he would to a stranger like Garry. Pindalest would then see that the government buys the herd at an inflated price. Garry would get $10,000 for his part in the swindle.
Lufton manages to outsmart Riling and move his herd unimpeded, but Riling and his men stampede and scatter the cattle back onto the reservation. It would take several days to gather the herd, more time than Lufton has before the deadline. Garry becomes disgusted when a man is killed in the stampede, and he switches sides. Amy still does not trust him. She suspects Garry of betraying the contents of a letter to Riling, unaware that Carol is enamored with Riling and is the one passing information to him. Eventually, Amy comes to trust (and fall in love with) Garry, especially after he defends her father from two of Riling's men. 
Question: Who are the people Riling has believing that his is working in their best interest?
answer:
the homesteaders.

Passage: There are over 20 miles (32 km) of hiking trails at Worlds End State Park. Most of the trails are rocky and steep, so hikers are encouraged to wear proper footgear and to be prepared for icy conditions during the cold winter months. As John Young writes in Hike Pennsylvania, "If you want to do some hiking in the Worlds End region, you should know that hiking here means climbing". Worlds End State Park is open during the winter months for snow mobiling and cross-country skiing. Most of the trails are too steep or rugged for either activity, but the park roads are open, as are trails on surrounding state forest lands.
Loyalsock Trail, often abbreviated LT, is a rugged 59.28-mile (95.40 km) hiking trail that stretches from near Loyalsockville, in Lycoming County on Pennsylvania Route 87 to north of Laporte in Sullivan County, just off U.S. Route 220. This trail follows the ridges and streams of the Loyalsock Creek watershed. The trail is primarily within the boundaries of Loyalsock State Forest and uses some old logging roads and abandoned railroad grades. The Loyalsock Trail was originally blazed in a yellow rectangle with a red stripe, and red can lids with a yellow "LT". Recently, the trail markers have been changed to a yellow disc with a red "LT".
Link Trail is a moderate 8.5-mile (13.7 km) trail marked with a red X on a yellow circle blaze. The trail starts at the Cabin Bridge in the park and follows Loyalsock Creek before it branches off and follows Double Run. The trail then ascends to Canyon Vista and heads out into Loyalsock State Forest where it links up with the Loyalsock Trail at the 55.33-mile (89.05 km) post. The Loyalsock Trail can be followed back for a 17.62 miles (28.36 km) long loop.
Canyon Vista Trail is a 3.5-mile (5.6 km) loop trail with blue blazes that passes through the eastern portion of the park and a stand of ash, sugar maple, and black cherry trees. This trail passes a maze-like jumble of blocky Pottsville Formation rocks known as the Rock Garden, adjacent to Canyon Vista. The vista is at an elevation of 1,750 feet (530 m) and "rewards the hiker with a spectacular view of the Loyalsock Creek gorge".
Worlds End Trail is a 3.25-mile (5.23 km) trail with yellow blazes that begins at the park office and ascends to an overlook of the swimming area. It then crosses the old Pioneer Road, which was used by some of the first settlers to the area, and enters the Loyalsock State Forest, ending at the 37.77-mile (60.78 km) post of the Loyalsock Trail, which can be followed back to the park office to make a loop 11.5 miles (18.5 km) long.
Butternut Trail is a 2.5-mile (4.0 km) trail marked with orange blazes that loops through a hardwood forest and crosses over Butternut Run. Two side trails connect Butternut Trail with the Loyalsock Trail. 
Question: What is the name of the trail that crosses Pioneer Rock?
answer:
Worlds End Trail.


question:
Passage: Chartwell is a country house near the town of Westerham, Kent in South East England. For over forty years it was the home of Winston Churchill. He bought the property in September 1922 and lived there until shortly before his death in January 1965. In the 1930s, when Churchill was excluded from political office, Chartwell became the centre of his world. At his dining table, he gathered those who could assist his campaign against German re-armament and the British government's response of appeasement; in his study, he composed speeches and wrote books; in his garden, he built walls, constructed lakes and painted. During the Second World War Chartwell was largely unused, the Churchills returning after he lost the 1945 election. In 1953, when again Prime Minister, the house became Churchill's refuge when he suffered a devastating stroke. In October 1964, he left for the last time, dying at his London home, 28, Hyde Park Gate, on 24 January 1965.
The origins of the estate reach back to the 14th century; in 1382 the property, then called Well-street, was sold by William-at-Well. It passed through various owners and in 1836 was auctioned, as a substantial, brick-built manor. In 1848, it was purchased by John Campbell Colquhoun, whose grandson sold it to Churchill. The Campbell Colquhouns greatly enlarged the house and the advertisement for its sale at the time of Churchill's purchase described it as an "imposing" mansion. Between 1922 and 1924, it was largely rebuilt and extended by the society architect Philip Tilden. From the garden front, the house has extensive views over the Weald of Kent, "the most beautiful and charming" Churchill had ever seen, and the determining factor in his decision to buy the house.
In 1946, when financial constraints forced Churchill to again consider selling Chartwell, it was acquired by the National Trust with funds raised by a consortium of Churchill's friends led by Lord Camrose, on condition that the Churchills retain a life-tenancy. After Churchill's death, Lady Churchill surrendered her lease on the house and it was opened to the public by the Trust in 1966. A Grade I listed building, for its historical significance rather than its architectural merit, Chartwell has become among the Trust's most popular properties; some 232,000 people visited the house in 2016, the fiftieth anniversary of its opening. 
Question: What is the full name of the person that rebuilt Chartwell between 1922 and 1924?
answer:

Philip Tilden.
