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?

Ex Output:
Patchi.

Passage: Although the publicity generated by Five Leaves Left was minor, Boyd was keen to build on what momentum there was. Drake's second album, 1971's Bryter Layter, again produced by Boyd and engineered by John Wood, introduced a more upbeat, jazzier sound.Disappointed by his debut's poor commercial performance, Drake sought to move away from his pastoral sound, and agreed to Boyd's suggestions to include bass and drum tracks. "It was more of a pop sound, I suppose," Boyd later said. "I imagined it as more commercial." Like its predecessor, the album featured musicians from Fairport Convention, as well as contributions from John Cale on two songs: "Northern Sky" and "Fly". Trevor Dann noted that while sections of "Northern Sky" sound more characteristic of Cale, the song was the closest Drake came to a release with chart potential. Cale used heroin during this period, and his older friend Brian Wells suspected that Drake was also using.Boyd and Wood were confident that Bryter Layter would be a success, but it sold fewer than 3,000 copies. Reviews were again mixed: while Record Mirror praised Drake as a "beautiful guitarist—clean and with perfect timing, [and] accompanied by soft, beautiful arrangements", Melody Maker described the album as "an awkward mix of folk and cocktail jazz".Soon after its release, Boyd sold Witchseason to Island Records, and moved to Los Angeles to work with Warner Brothers to develop film soundtracks. The loss of his mentor, coupled with the album's poor sales, led Drake into further depression. His attitude to London had changed: he was unhappy living alone, and visibly nervous and uncomfortable performing at a series of concerts in early 1970. In June, Drake gave one of his final live appearances at Ewell Technical College, Surrey. Ralph McTell, who also performed that night, remembered: "Nick was monosyllabic. At that particular gig he was very shy. He did the first set and something awful must have happened. He was doing his song 'Fruit Tree' and walked off halfway through it."In 1971, Drake's family persuaded him to visit a psychiatrist at St Thomas's Hospital, London. He was prescribed antidepressants, but felt uncomfortable and embarrassed about taking them, and tried to hide the fact from his friends. He worried about their side effects and was concerned about how they would react with his regular cannabis use.Island Records urged Drake to promote Bryter Layter through interviews, radio sessions and live appearances. Drake, who by this time was smoking what Kirby described as "unbelievable amounts" of cannabis and exhibiting "the first signs of psychosis", refused. Disappointed by the reaction to Bryter Layter, he turned his thoughts inwards, and withdrew from family and friends. He rarely left his flat, and then only to play an occasional concert or to buy drugs. His sister recalled: "This was a very bad time. He once said to me that everything started to go wrong from [this] time on, and I think that was when things started to go wrong.". 
Question: What is the last name of the person who agreed to include bass and drum tracks?

Ex Output:
Northern Sky.

Passage: In 1865, Burges met John Patrick Crichton-Stuart, 3rd Marquess of Bute. This may have resulted from Alfred Burges's engineering firm, Walker, Burges and Cooper, having undertaken work on the East Bute Docks in Cardiff for the second Marquess. The 3rd Marquess became Burges's greatest architectural patron; both were men of their times; both had fathers whose industrial endeavours provided the means for their sons' architectural achievements, and both sought to "redeem the evils of industrialism by re-living the art of the Middle Ages".On his succession to the Marquessate at the age of one, Bute inherited an income of £300,000 a year, and, by the time he met Burges, he was considered the richest man in Britain, if not the world. Bute's wealth was important to the success of the partnership: as Burges himself wrote, "Good art is far too rare and far too precious ever to be cheap." But, as a scholar, antiquarian, compulsive builder and enthusiastic medievalist, Bute brought more than money to the relationship and his resources and his interests allied with Burges's genius to create what McLees considers to be "Bute's most memorable overall achievement."
However occasioned, the connection lasted the rest of Burges's life and led to his most important works. To the Marquess and his wife, Burges was the "soul-inspiring one". The architectural writer Michael Hall considers Burges's rebuilding of Cardiff Castle and the complete reconstruction of the ruin of Castell Coch, north of the city, as representing his highest achievements. In these buildings, Crook contends that Burges escaped into "a world of architectural fantasy" which Hall describes as "amongst the most magnificent the Gothic Revival ever achieved.". 
Question: What specific meeting may have resulted from Alfred Burges's engineering firm having undertaken work on the East Bute Docks in Cardiff for the second Marquess?

Ex Output:

Burges met John Patrick Crichton-Stuart, 3rd Marquess of Bute.
