Please answer this: Read the following paragraph and extract the answer for the question: When was the Chicxulub crater discovered? The Chicxulub crater (; Mayan: [t'ikulu]) is an impact crater buried underneath the Yucatan Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth. The date of the impact coincides precisely with the CretaceousPaleogene boundary (KPg boundary), slightly less than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from the event was the cause of the CretaceousPaleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs. The crater is estimated to be 150 kilometres (93 miles) in diameter and 20 km (12 mi) in depth, well into the continental crust of the region of about 1030 km (6.218.6 mi) depth. It is the second largest confirmed impact structure on Earth and the only one whose peak ring is intact and directly accessible for scientific research.The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatan during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater and gave up his search. Later, through contact with Alan Hildebrand in 1990, Penfield obtained samples that suggested it was an impact feature. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas. In 2016, a scientific drilling project drilled deep into the peak ring of the impact crater, hundreds of meters below the current sea floor, to obtain rock core samples from the impact itself. The discoveries were widely seen as confirming current theories related to both the crater impact and its effects.

Please answer this: Read the following paragraph and extract the answer for the question: What is the last name of the person who claims that most of the money spent came from the band's own funds? The vocals were taped in Britannia Row and Protocol studios between May and June 1991, the first time vocalist Bilinda Butcher was involved in the recording. Shields and Butcher hung curtains on the window between the studio control room and the vocal booth, and only communicated with the engineers when they would acknowledge a good take by opening the curtain and waving. According to engineer Guy Fixsen, "We weren't allowed to listen while either of them were doing a vocal. You'd have to watch the meters on the tape machine to see if anyone was singing. If it stopped, you knew you had to stop the tape and take it back to the top." On most days, the couple arrived without having written the lyrics for the song they were to record. Dutt recalled: "Kevin would sing a track, and then Bilinda would get the tape and write down words she thought he might have sung".In July 1991, Creation agreed to relocate the production to Eastcote studio, following unexplained complaints from Shields. However, the cash-poor Creation Records was unable to pay the bill for their time at Britannia Row, and the studio refused to return the band's equipment. Dutt recalled, "I don't know what excuse Kevin gave them for leaving. He had to raise the money himself to get the gear out." Shields' unpredictable behaviour, the constant delays, and studio changes were having a material effect on Creation's finances and the health of their staff. Dutt later said he had been desperate to leave the project, while Creation's second-in-command Dick Green had a nervous breakdown. Green recalled, "It was two years into the album, and I phoned Shields up in tears. I was going 'You have to deliver me this record'."Shields and Butcher became afflicted with tinnitus, and had to delay recording for further weeks while they recovered. Concerned friends and band members suggested this was a result of the unusually loud volumes the group played at their shows, which Shields dismissed as "Ill-informed hysteria." Although Alan McGee was still positive about...

Answer: Shields

Please answer this: Read the following paragraph and extract the answer for the question: What is the name of the person who shows, through his playing skill, that grunge guitarists do not have to be sloppy players to rebel against mainstream music? Grunge guitarists "flatly rejected" the virtuoso "shredding" guitar solos that had become the centerpiece of heavy metal songs, instead opting for melodic, blues-inspired solos focusing "on the song, not the guitar solo". Jerry Cantrell of Alice in Chains stated that solos should be to serve the song, rather than to show off a guitarist's technical skill. In place of the strutting guitar heroes of metal, grunge had "guitar anti-heroes" like Cobain, who showed little interest in mastering the instrument.In Will Byers' article "Grunge committed a crime against musicit killed the guitar solo", in The Guardian, he states that while the guitar solo managed to survive through the punk rock era, it was weakened by grunge. He states that when Kurt Cobain played guitar solos that were a restatement of the main vocal melody, fans realized that they did not need to be a Jimi Hendrix-level virtuoso to play the instrument; he says this approach helped to make music feel accessible by fans in a way not seen since the 1960s folk music movement. The producer of Nirvana's Nevermind, Butch Vig, stated that this album and Nirvana "killed the guitar solo". Soundgarden guitarist Kim Thayil stated he feels in part to be responsible for the "death of the guitar solo"; he said that his punk rocker aspects made him feel that he did not want to solo, so in the 1980s, he preferred to make noise and do feedback during the guitar solo. Baeble Music calls the grunge guitar solos of the 1990s "..raw", "sloppy" and "basic".Not all sources support the "grunge killed the guitar solo" argument. Sean Gonzalez states that Pearl Jam has plentiful examples of guitar solos. Michael Azerrad praises the guitar playing of Mudhoney's Steve Turner, calling him the "... Eric Clapton of grunge", a reference to the British blues guitarist who Time magazine has named as number five in their list of "The 10 Best Electric Guitar Players". Pearl Jam guitarist Mike McCready has been praised for his blues-influenced, rapid licks. The Smashing Pumpkins'...
