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.

Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?
answer:
Broderick.

Passage: By the end of the 1960s, Ornette Coleman had become one of the most influential musicians in jazz after pioneering its most controversial subgenre, free jazz, which jazz critics and musicians initially derided for its deviation from conventional structures of harmony and tonality. In the mid-1970s, he stopped recording free jazz, recruited electric instrumentalists, and pursued a new creative theory he called harmolodics. According to Coleman's theory, all the musicians are able to play individual melodies in any key, and still sound coherent as a group. He taught his young sidemen this new improvisational and ensemble approach, based on their individual tendencies, and prevented them from being influenced by conventional styles. Coleman likened this group ethic to a spirit of "collective consciousness" that stresses "human feelings" and "biological rhythms", and said that he wanted the music, rather than himself, to be successful. He also started to incorporate elements from other styles into his music, including rock influences such as the electric guitar and non-Western rhythms played by Moroccan and Nigerian musicians.Of Human Feelings was a continuation of the harmolodics approach Coleman had applied with Prime Time, an electric quartet introduced on his 1975 album Dancing in Your Head. The group comprised guitarists Charlie Ellerbee and Bern Nix, bassist Jamaaladeen Tacuma, and drummers Ronald Shannon Jackson and Denardo Coleman, Ornette Coleman's son. Tacuma was still in high school when Coleman enlisted him, and first recorded with Prime Time in 1975 for the album Body Meta, which was released in 1978. Tacuma had played in an ensemble for jazz organist Charles Earland, but Earland dismissed him as he felt audiences gave excessive attention to his playing. Coleman found Tacuma's playing ideal for harmolodics and encouraged him not to change. Although Coleman's theory initially challenged his knowledge and perception of music, Tacuma came to like the unconventional role each band member was given as a soloist and melodist: "When we read Ornette's music we have his notes, but we listen for his phrases and phrase the way he wants to. I can take the same melody, then, and phrase it like I want to, and those notes will determine the phrasing, the rhythm, the harmony – all of that.". 
Question: What is the last name of the person who taught his sidemen this new improvisational and ensemble approach?
answer:

Coleman.
