Input: Consider Input: Question: Is the English hard rock band that Wolfmother covered at the UK Music Hall of Fame still active? Passage:After its success in Australia, Wolfmother was later released internationally in early 2006 – on 24 April in the UK, where it reached number 25 on the UK Albums Chart, and on 2 May in the US, where it reached number 22 on the Billboard 200. A number of singles were released from the album, including "Woman" which reached number 34 in Australia, number 31 on the UK Singles Chart, and number 7 on the US Billboard Mainstream Rock chart. The song later won the Grammy Award for Best Hard Rock Performance at the 49th Annual Grammy Awards, the nomination for which Heskett had previously described as "an honour". The final single from the album, "Joker & the Thief", later reached the top ten in Australia. The subsequent worldwide tour included appearances at festivals such as Fuji Rock in Tokyo, Japan, the inaugural Virgin Festival, and Reading and Leeds Festivals in the UK. On 14 November 2006, the band performed a cover version of "Communication Breakdown" by English hard rock band Led Zeppelin as a tribute to the band for their induction into the UK Music Hall of Fame.

Input: Consider Input: Question: In which state did Don Cardwell no-hit the St. Louis Cardinals 4-0 in the second game of a doubleheader? Passage:Cardwell was traded to the Cubs on May 13, 1960, for Tony Taylor. Two days later, he no-hit the St. Louis Cardinals 4–0 in the second game of a doubleheader at Wrigley Field—the first no-hitter ever thrown by a pitcher in his first start with a new team. The lone baserunner for the Cardinals was by a walk from Cardwell to Alex Grammas with one out in the first inning; Cardwell then retired the next 26 batters. Two ninth-inning catches enabled Cardwell to secure the no-hitter: the first catch by Cubs right fielder George Altman on a Carl Sawatski line drive for the first out of the inning, and the second catch by Cubs left fielder Walt "Moose" Moryn on Joe Cunningham's sinking line drive to end the game, Moryn catching the ball just inches off the ground. Cardwell finished the season 9–16 and the Cubs 60–94 despite his no-hitter. Cardwell also showed his hitting ability in 1960, getting 16 hits including five home runs in 77 at bats for a .208 batting average.

Input: Consider Input: Question: What was the main evolutionary pressure? Passage:The time from roughly 15,000 to 5,000 BC was a time of transition, and swift and extensive environmental change, as the planet was moving from an Ice age, towards an interstadial (warm period). Sea levels rose dramatically (and are continuing to do so), land that was depressed by glaciers began lifting up again, forests and deserts expanded, and the climate gradually became more modern. In the process of warming up, the planet saw several "cold snaps" and "warm snaps", such as the Older Dryas and the Holocene climatic optimum, as well as heavier precipitation. In addition, the Pleistocene megafauna became extinct due to environmental and evolutionary pressures from the changing climate. This marked the end of the Quaternary extinction event, which was continued into the modern era by humans. The time around 11,700 years ago (9700 BC) is widely considered to be the end of the old age (Pleistocene, Paleolithic, Stone age, Wisconsin Ice Age), and the beginning of the modern world as we know it.
