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: In 1987, James Brennan plans to have a summer vacation in Europe after graduating with a comparative literature degree from Oberlin College and to attend a journalism graduate school at Columbia University when his holidays end. A few days after his graduation, his parents advise him to seek a part-time job rather than going to Europe when they unexpectedly announce that financial problems have taken a toll on them and they would be unable to financially support him.
James gets a job at Adventureland, a local amusement park in his hometown of Pittsburgh, Pennsylvania, where his childhood friend Tommy Frigo works. Assistant manager Bobby assigns James to the games area. He meets his co-workers: sarcastic Joel; Bobby's wife and park manager Paulette; Sue O'Malley; Mark; the alluring Lisa P.; and the park's technician, Mike Connell, a part-time musician. Another games worker, Emily "Em" Lewin, saves James from being stabbed by a lying, cheating customer.
With her father and stepmother away, Em throws a party and gets to know James. During the conversation, Em persuades James to join her in the house's swimming pool. After Em leaves the pool, James follows only to jump back into the water in humiliation when Frigo announces to the partygoers that he saw James having an erection while leaving the pool. After the party, Connell, who has been having an affair with Em, comes over to further pursue it.
Question: What's the name of the park technician's workplace?

Ex Output:
Adventureland.

Passage: Prior to the introduction of the current format of semifinals (deltavlingar) in 2002, the competition was usually a single live show. Under the current system, four semifinals are broadcast at 20:00 CET on consecutive Saturday nights. The semi-finals begin in early February, and seven songs compete in each show.
Unlike in the final, no juries are used; televoting decides the results. The songs are performed live with telephone lines open for the first round of voting; two songs with the fewest votes do not qualify to the second round. The top five battle for a place in the final and Andra chansen round the 1st and 2nd placed songs qualifying to the final, and the 3rd and 4th placed songs progressing to Andra chansen.
Both finalists reprise their entries at the end of the broadcast. The organisation of a semi-final system for Melodifestivalen popularised televised heats at national Eurovision selections. A similar system was adopted by the Eurovision itself in 2004.
The Second Chance round (Andra chansen) is the fifth heat in which the remaining four entries to the final are chosen. The third- and fourth-placed songs from each semi-final (eight songs in total) compete in the event. The first Second Chance round in 2002 had a panel of former winners decide the two finalists. Between 2003 and 2006, the semi-final performances were re-broadcast, and a round of voting narrowed the songs to three or four. Another round then determined the two finalists. The programme was broadcast on the Sunday afternoon after the fourth semi-final. It was held in a smaller venue than those that would have hosted the semi-finalssuch as Berns Salonger in Stockholm, which hosted the Second Chance round in 2005.
In 2007, the Second Chance round became a full semi-final, taking place in a venue comparable in size to those hosting the others. The expanded Second Chance takes place on a Saturday night, adding an extra week to the event's timetable. The format of voting also changed with the introduction of a knock-out system. The system pairs the eight songs off against each other, then narrows them down to four before pairing them off again. The winners of the two-second round pairings go through to the final. The two finalists do not reprise their songs at the end of the programme.
In 2015, the system was changed again. The eight songs are divided into four duels, with one song from each duel qualifying into the final, bringing the number of finalists to 12.
Question: What system pairs the eight songs off against each other?

Ex Output:
a knock-out system.
