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?

Ex Output:
Worlds End Trail.

Passage: The crew of a malfunctioning alien cargo ship make an emergency landing on Earth. This draws the attention of four sexually-frustrated humans in a nearby park: Oliver and Prudence (a mild-mannered professional and his highly-strung fiancée), Willy (a bumbling shop assistant) and Cliff (a middle-aged man).
Oliver, Prudence, Willy and Cliff wander into the ship and encounter three aliens resembling human women: engineer Partha, nurse Cosia and the captain, known only as Skipper. Willy inadvertently drops some pornographic magazines that he has recently bought. The aliens mistake some approaching cows for a hostile force and hurriedly take off, despite warnings from the long-suffering computer about the precarious state of the ship's systems. Resuming their original course, they study their guests in detail. Fascinated by the anatomy of the males, they decide to sell them to a zoo for exotic lifeforms on a distant planet. They also debate the significance of the acts depicted in Willy's magazines. Partha is particularly keen to emulate them and enthusiastically has sex with Cliff.
Skipper, Cosia and Partha subject the males to a series of tests to learn more about their abilities. Oliver and Cliff fail miserably. However, Willy, looking for his magazines, beats Skipper's combat simulation by unknowingly evading her attacks, causing her to collapse with exhaustion and infer that he is a stronger being. While conducting a physical examination on Willy, Cosia discovers that his biology is more advanced than anything known to their species; encouraging Cosia with exaggerated claims about his sexual prowess, Willy loses his virginity to her. Later, he passes an intelligence test by a fluke and has sex with Partha. 
Question: Who decides to sell people to a zoo for exotic lifeforms on a distant planet?

Ex Output:
Skipper.

Passage: Laurel and Hardy are seated at a dockside where Stan is fishing. Ollie sees a notice in a newspaper which says one Ebeneezer Laurel has died and left a large estate. Parties interested in the estate should go to the Laurel mansion for the reading of the will. Stan can't remember if Ebeneezer is a relative or not but they decide to go to the mansion anyway. They arrive during a thunderstorm and discover that Ebeneezer had been murdered and that the police had placed the notice in the newspaper to draw all of the relatives together to find out who committed the crime.
Stan and Ollie are shown to a bedroom to sleep overnight, which is the room in which Ebeneezer was murdered. They hear a strange noise and in the darkness see a pair of eyes which turns out to be a cat. They then hear a scream and decide to investigate.
Meanwhile, the butler is calling all of the relatives to a study telling them they have a phone call. After sitting in a chair and lifting the handset of the phone, the lights go out, there is a scream and a sound like a door slamming, and the relative is never seen again. Stan and Ollie return to their bedroom and get into the bed but a bat has flown into their room and is under their covers, which causes them to panic and run downstairs.
All of the other relatives have now disappeared and the butler calls Stan and Ollie to take a telephone call in the study. Ollie sits in the chair to take the call. This time, however, the lights stay on and it is revealed that the chair is affixed to a trapdoor into which each of the other relatives vanished. Ollie falls through the trapdoor, but is saved due to his having become wedged in the chair. The murderer (a man dressed in drag) appears through a secret door with a knife. A fight ensues, but then Stan and Ollie both wake up from a dream, fighting over Stan's fishing line at the dockside and then falling into the water. 
Question: What is the last name of the person who can't remember is Ebeneezer Laurel is a relative or not?

Ex Output:

Laurel.
