Q: Passage: A paleontologist named Zack takes his nephew Ricky and niece Jade on a fossil hunt. While alone, Ricky is met by a talking raven, who turns into an Alexornis named Alex. He tells him of a story set in the Cretaceous period 70 million years ago. Patchi is the smallest in a litter of Pachyrhinosaurus hatchlings, and is often bullied by his older brother Scowler. Their father Bulldust is the leader of the Pachyrhinosaurus herd. Alex, who is Patchi's mentor, tries to help Patchi impress a female Pachyrhinosaurus named Juniper, but her herd migrates south without him.
Bulldust moves his herd south as well, but when they try to pass through a forest, they are forced to flee when a storm strikes and a fire erupts. Taking advantage of the chaos, a pack of Gorgosaurus attacks the scattered herd. They kill the rest of Patchi and Scowler's family while their leader Gorgon fights and kills Bulldust. Afterwards, Patchi's herd (now led by Bulldust's rival Major) combines with Juniper's as they continue their migration. There, Gorgon's pack attacks them again. In the ensuing chaos, Patchi, Scowler, and Juniper fall into a river and are swept downstream to the ocean, with Alex following them from above. At a beach, Scowler follows a herd of Edmontosaurus to find food, callously leaving Patchi and Juniper behind. The two make their way through a forest and eventually are able to find their herd and Scowler. 
Question: What are the names of the two Pachyrhinosausus that make their way through the forest to find their heard?

A: Patchi.

Q: Passage: Forty-eight Non-Indian people visited Yosemite Valley in 1855, including San Francisco writer James Mason Hutchings and artist Thomas Ayres. Hutchings wrote an article about his experience that was published in the July 12, 1855, issue of the Mariposa Gazette and Ayres' sketch of Yosemite Falls was published in late 1855; four of his drawings were presented in the lead article of the July 1856 and initial issue of Hutchings' Illustrated California Magazine. The article and illustrations created tourist interest in Yosemite and eventually led to its protection.Ayres returned in 1856 and visited Tuolumne Meadows in the area's high country. His highly detailed angularly exaggerated artwork and his written accounts were distributed nationally and an art exhibition of his drawings was held in New York City.
Hutchings took photographer Charles Leander Weed to Yosemite Valley in 1859; Weed took the first photographs of the valley's features, which were presented to the public in a September exhibition held in San Francisco. Hutchings published four installments of "The Great Yo-semite Valley" from October 1859 to March 1860 in his magazine and re-published a collection of these articles in his Scenes of Wonder and Curiosity in California, which remained in print into the 1870s.
Carleton Watkins exhibited his 17 by 22 in (43 by 56 cm) Yosemite views at the 1867 Paris International Exposition.Photographer Ansel Adams made his first trip to Yosemite in 1916; his photographs of the valley made him famous in the 1920s and 1930s. Adams willed the originals of his Yosemite photos to the Yosemite Park Association, and visitors can still buy direct prints from his original negatives. The studio in which the prints are sold was established in 1902 by artist Harry Cassie Best.Milton and Houston Mann opened a toll road to Yosemite Valley in 1856, up the South Fork of the Merced River. They charged the then considerable sum of two dollars per person until the road was bought by Mariposa County, after which it became free.
In 1856, settler Galen Clark discovered the Mariposa Grove of giant sequoia at Wawona, an indigenous encampment in what is now the southwestern part of the park. Clark completed a bridge over the South Fork of the Merced River in 1857 at Wawona for traffic headed toward Yosemite Valley and provided a way station for travelers on the road the Mann brothers built to the valley.Simple lodgings, later called the Lower Hotel, were completed soon afterward; the Upper Hotel, later renamed Hutchings House and eventually known as Cedar Cottage, was opened in 1859. In 1876, the more substantial Wawona Hotel was built to serve tourists visiting the nearby grove of big trees and those on their way to Yosemite Valley. Aaron Harris opened the first campground business in Yosemite in 1876. 
Question: What is the last name of the person in whose magazine four installments of "The Great Yo-semite Valley" were published?

A: Hutchings.

Q: Passage: Amidst mourning with her family, she focused on work to deal with the grief, avoiding any news coverage of her sibling's death. She commented, "it's still important to face reality, and not that I'm running, but sometimes you just need to get away for a second." During this time, she ended her seven-year relationship with Jermaine Dupri.Several months later, Jackson performed a tribute to Michael at the 2009 MTV Video Music Awards, performing their duet "Scream". MTV stated "there was no one better than Janet to anchor it and send a really powerful message."

For promotion, she performed a medley of hits at the American Music Awards, Capital FM's Jingle Bell Ball at London's O2 arena, and The X-Factor. The album's promotional single "Make Me", produced with Rodney "Darkchild" Jerkins, debuted in September. It became Jackson's nineteenth number one on the Hot Dance Club Songs chart, making her the first artist to have number-one singles in four separate decades.Later that month, Jackson chaired the inaugural benefit of amfAR, The Foundation for AIDS Research, held in Milan in conjunction with fashion week. The foundation's CEO stated "We are profoundly grateful to Janet Jackson for joining amfAR as a chair of its first event in Milan.... She brings incomparable grace and a history of dedication to the fight against AIDS." The event raised a total of $1.1 million for the nonprofit organization.
