Question: Passage: Slint formed in 1987 in Louisville, Kentucky, from the remnants of the punk rock band Squirrel Bait; the founding members included Brian McMahan (guitar, vocals), David Pajo (guitar), Britt Walford (drums) and Ethan Buckler (bass guitar). The band's debut album, the Steve Albini-produced Tweez, was released on the group's self-owned label Jennifer Hartman Records and Tapes. The album's sound has been described as a combination of "scratchy guitars, thumping bass lines and hard hitting drums". Buckler promptly left the band out of dissatisfaction with Albini's production, and was replaced with Todd Brashear. The band's second recording was for the instrumental extended play Slint, which included a new version of "Rhoda" from Tweez. The EP, which would not be released until 1994, was a departure from Tweez's sound and reflected the band's new musical direction.After the band ended its brief tour in support of Tweez, most of its members attended college. Around this time McMahan and Walford began writing together for the band's next record, creating six new songs which the band practiced throughout the summer of 1990. Slint entered River North Records in August 1990 to record Spiderland. At that time there were no vocals or lyrics prepared for the album, so the band wrote them while in the studio. The album's producer, Brian Paulson, was known for his "live" recording style in the studio, with minimal takes. Paulson recalled "It was weird while I was doing [Spiderland] because I remember sitting there, and I just knew there was something about it. I've never heard anything like this. I'm really digging this but it's really fucking weird."The recording sessions for Spiderland are reputed to have been difficult for the members of the band and were, according to AllMusic, "intense, traumatic and one more piece of evidence supporting the theory that band members had to be periodically institutionalized during the completion of the album." Rumors circulated that at least one member of Slint had been checked into a psychiatric hospital. Walford later addressed these stories in an article in Select by saying, "[We were] definitely trying to be serious about things, pretty intense, which made recording the album kinda stressful." The recording was completed in four days.
Question: What is the full name of the person that Todd Brashear replaced?

Answer: Ethan Buckler.

Question: Passage: Born without an immune system, Jimmy Livingston is forced to live in a sterilized dome in his bedroom, earning him the nickname "Bubble Boy" by his neighbors. Jimmy's overbearing and devout Christian mother only exposes him to Highlights magazine and the Land of the Lost for entertainment. When he is a teenager, a girl named Chloe moves in next door. Jimmy is immediately taken with her, and eventually befriends her despite his mother's discouragement.
Chloe visits Jimmy and tells him that she is leaving for Niagara Falls to marry her boyfriend, Mark, in three days. Jimmy realizes that Chloe cares for him. Realizing how much he cares for her, Jimmy builds a mobile bubble suit and runs away from home, determined to stop the wedding.
On the first day of his journey, he's unable to afford a bus ride to Niagara Falls, but is picked up by an overly enthusiastic cult on a pilgrimage towards enlightenment. By this time, Jimmy's mother has discovered her son missing, so she and her husband set off to find Jimmy.
While traveling through the desert, Jimmy meets Slim, a biker with a flat tire. Jimmy offers to fix the flat with some patches and the two become friends. Elsewhere, Gil, the leader of the cult Jimmy met, has revealed that their messiah is "the round one," and that whoever rejects him will suffer. The group who abandoned Jimmy set off to find him. Jimmy and Slim have traveled to Las Vegas for traveling money. However, Slim gets caught up in the Vegas life so Jimmy goes on without him. The cult runs into Slim in Vegas while asking for directions. Slim recognizes them from Jimmy's story and threatens them, only to have his bike destroyed by the cult bus.
Soon Jimmy accidentally boards a train belonging to Dr. Phreak, a small man who collects freaks and shows them off to the public for money. When Dr. Phreak tried to recruit Jimmy to his show, Jimmy knocks him unconscious; allowing for Jimmy and the freaks to go their own way.
Question: What is the last name of the person that is trying to stop Chloe from marrying her boyfriend?

Answer: Livingston.

Question: Passage: Bartlett decided to send a team back to establish the exact location of the island that the Anderson party had approached, and to determine if Anderson had actually landed there. An injury to his knee ruled Mamen out from this mission, which was undertaken by ship's steward Ernest Chafe, with the Inuit pair, Kataktovik and Kuraluk. Chafe's group came within 2 miles (3 km) of Herald Island before being stopped by open water. A careful examination through binoculars revealed no signs of the missing party, and Chafe concluded that Anderson and company had not reached the island. Chafe and his party then returned to Shipwreck Camp.Meanwhile, on 4 February, Mackay and his group (Murray and Beuchat, joined by seaman Stanley Morris) announced they were leaving the next day, to seek land. Mackay presented Bartlett with a letter dated 1 February that began: "We, the undersigned, in consideration of the present critical situation, desire to make an attempt to reach the land." The letter requested appropriate supplies, and concluded by emphasising that the journey was on their own initiative and absolving Bartlett from all responsibilities. Bartlett allocated them a sledge, a tent, six gallons of oil, a rifle and ammunition and food for 50 days. They left on 5 February; the last sighting of them was a few days later, by Chafe and the Inuit, returning from their abortive trip to Herald Island. They found Mackay's party struggling to make headway, with some of their provisions lost and clothing and other equipment discarded to lighten their load. Beuchat in particular was in a distressed state, nearly delirious and in the throes of hypothermia. However, the party refused assistance and rejected Chafe's pleas that they return with him to Shipwreck Camp. Thereafter the only hint of their fate was a sailor's scarf belonging to Morris, later found buried in an ice floe. It was assumed that the four had either been crushed by the ice, or had fallen through it.
Question: What were the last names of the people in Mackay's group?

Answer:
Murray.
