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.

Passage: Ultrasonic tells the tale of Simon York music teacher, married, soon to be father. Simon plays in a band and dreams of one day getting paid to write music. For now, however, money is tight and Simon shelling out $2000 to record an album is an additional cause of stress on his marriage to Ruth.
Jonas is Ruth's troubled brother and spends his days handing out flyers and trying to, "open peoples' eyes," to his theories of conspiracies and injustices in the world. One night Simon hears what he thinks is a very real sound in an alleyway. The sound does not disappear and remains audible from his house. Ruth doesn't hear it and she dismisses it, claiming that his ears are
ringing from years of loud music.
Jonas' reaction to Simon's ailment is much different than Ruth's. Jonas believes Simon and, after doing some research, believes that what Simon is hearing is in fact a government experiment, which utilizes an ultrasonic auditory signal to control the minds of all who hear it. Simon, with some prodding from Ruth, goes to visit an ear doctor who informs him that his test results show Simon's hearing to be least 6,000 Hz higher than the average human. This convinces Jonas that his theory is correct, and the two of them embark on a journey to get to the bottom of the sound experiment and stop the noise.
Whose sister persuades the music teacher to have his ears checked?

Passage: Leonard Harrison State Park is a 585-acre (237 ha) Pennsylvania state park in Tioga County, Pennsylvania, in the United States. It is on the east rim of the Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania, which is 800 feet (240 m) deep and nearly 4,000 feet (1,200 m) across here. It also serves as headquarters for the adjoining Colton Point State Park, its sister park on the west rim of the gorge. Leonard Harrison State Park is known for its views of the Pine Creek Gorge, and offers hiking, fishing and hunting, whitewater boating, and camping. The park is in Shippen and Delmar Townships, 10 miles (16 km) west of Wellsboro at the western terminus of Pennsylvania Route 660.
Pine Creek flows through the park and has carved the gorge through five major rock formations from the Devonian and Carboniferous periods. Native Americans once used the Pine Creek Path along the creek. The path was later used by lumbermen, and then became the course of a railroad from 1883 to 1988. Since 1996, the 63.4-mile (102.0 km) Pine Creek Rail Trail has followed the creek through the park. The Pine Creek Gorge was named a National Natural Landmark in 1968 and is also protected as a Pennsylvania State Natural Area and Important Bird Area, while Pine Creek is a Pennsylvania Scenic and Wild River. The gorge is home to many species of plants and animals, some of which have been reintroduced to the area.
Although the Pine Creek Gorge was clearcut in the 19th and early 20th centuries, it is now covered by second growth forest, thanks in part to the conservation efforts of the Civilian Conservation Corps (CCC) in the 1930s. The park is named for Leonard Harrison, a Wellsboro lumberman who cut the timber there, then established the park, which he donated to the state in 1922. The CCC improved the park and built many of its original facilities. Since a successful publicity campaign in 1936, the park has been a popular tourist destination and attracts hundreds of thousands of visitors each year. Leonard Harrison State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of Parks for its "25 Must-See Pennsylvania State Parks" list, which praised its "spectacular vistas and a fabulous view of Pine Creek Gorge, also known as Pennsylvania's Grand Canyon".
What is the name of the place whose sister park is on the west rim of the gorge?

Passage: Santamental, released in October 2003, is a collaborative project featuring several prominent musicians such as guitarists Eddie Van Halen, Slash, Steve Vai, and drummer Gregg Bissonette. When Lukather's record company, Bop City Records, approached him about recording a Christmas album, he responded with a quip about his suitability for the project. The company wanted him to do the record knowing he would approach the project with a unique angle and produce something different from the typical Christmas album. Lukather recruited keyboardist Jeff Babko and guitarist Larry Carlton, who Lukather had worked with previously, to help arrange the songs. The project was a challenge to Lukather, who had to be creative to turn the traditionally simple songs into something interesting for listeners without altering the fundamental structures. He said of the album, "But I never dreamt in a million years that I'd do a Christmas record."The musicians Lukather chose for Santamental, most of whom were involved in the hard-rock genre, lent a heavy feel to the album. Van Halen recorded guitar tracks for "Joy to the World" after not having been in the studio for some time but immediately made an impression on Lukather with his level of playing. Vai provided guitar work for "Carol of the Bells" along with Lukather's son Trevor, then 14 years old. Slash, who recorded his part in one take, played on the Lukather/Stan Lynch composition "Broken Heart for Christmas". Lukather spoke highly of Slash after the project, calling him the "Keith Richards of our generation". Well-known session guitarist Michael Landau played on the song "Look Out For Angels", and there is a version of "Jingle Bells" featuring a big band and sung by Sammy Davis, Jr. Santamental was recorded in six days, after which Lukather proclaimed it "his first and last Christmas album".
What is the first name of the person who recorded guitar tracks for "Joy to the World" after not having been in the studio for some time?
