Input: Consider Input: Question: What city did Mathews work in for Wrestlemania XXVII? Passage:In late 2010, Mathews often worked as the color commentator on Raw due to Jerry Lawler's increased in-ring competition. On April 3, 2011, Mathews commentated the majority of WrestleMania XXVII, though he received a 'Stone Cold Stunner' from an angered Stone Cold Steve Austin, cutting his night short. The following night on Raw, Mathews found himself aligned with Jerry Lawler, and against Michael Cole. He then became the alternate spokesman for the Anonymous Raw General Manager, when Michael Cole was not commentating. He then using the new catchphrase "The Anonymous Raw General Manager says...", before reading each e-mail. On the April 25 episode of Raw, Mathews announced that the Jim Ross and Jerry Lawler vs. Michael Cole and Jack Swagger match at Extreme Rules will be a Country Whipping match, which Cole and Swagger won. At the following pay-per-view, Over the Limit, Mathews supported Lawler, Bret Hart and Eve Torres in having Michael Cole kiss Lawler's foot. The following night, again as the spokesman for the anonymous Raw General Manager, Mathews read the e-mail that denied The Miz's request for another title shot, seemingly done with John Cena. He left the Raw broadcasting table the following week, after Cole and Lawler reconciled, though he remained on the show as a backstage interviewer and backup commentator.

Input: Consider Input: Question: What is one key difference between the Indus Valley civilization and early Vedic civilizations? Passage:The book discusses four prehistoric migrations in India. The book mentions that the Harappans were a mixture of Zagros agriculturists and First Indians, a wave of migrants who came from Africa into Arabia and then reached India around 65,000 years ago. Citing recent DNA evidence, the book traces the subsequent large migrations of anatomically modern humans into India—of agriculturalists from Iran between 7000 and 3000 BCE and Indo-European languages speaking pastoralists from the Central Asian Steppe (Aryans) between 2000 and 1000 BCE, among others. Tony Joseph used pizza as a metaphor to explain the break-up of subcontinental society. The book also discusses about similarities and differences between Indus Valley civilization and early Vedic civilization. The book mentions that ‘Aryan’ culture was most likely the result of interaction, adoption and adaptation among those who brought Indo-European languages to India and those who were already well-settled inhabitants of the region, and that Sanskrit and Vedas developed in the Indian subcontinent. Various tribes like the Andamanese and the Semang (Malay Peninsula), the Mani (Thailand) and the Aeta people (the Philippines) were the earliest inhabitants of Southeast Asia. According to Joseph, Proto-Dravidian is related to the Elamitic language of Iran. Caste system in India is a recent social system, reflected in sharply reduced inter-marriage (endogamy) and genetic mixing after 100 AD. This book also takes into account the path-breaking DNA research and findings from geneticist David Reich's research.

Input: Consider Input: Question: How many songs did McCoy write on Two Steps from the Move? Passage:Hanoi Rocks released their first album in 1981 titled Bangkok Shocks, Saigon Shakes, Hanoi Rocks, with eight out of ten tracks written by McCoy. The album was produced by Andy McCoy and Michael Monroe who were known as "The Muddy Twins". In 1982 Hanoi Rocks recorded and released their second studio album Oriental Beat in London. The original cover's back side featured Andy McCoy's then girlfriend Anna's naked breasts painted blue and red with "Hanoi Roxx" written across it. After the album's release, the band moved to London the same year, and subsequently fired drummer Gyp Casino before hiring Hanoi Rocks fan Nicholas Dingley, better known as Razzle, as drummer. The line-up with Razzle is considered the definitive version of Hanoi Rocks. Later that year the band released Self Destruction Blues, which had Razzle on the cover, but he didn't play on the album, because it was actually a compilation of old singles. The tour for the album took the band to Asia for the first time. The next year 1983, the band released Back to Mystery City and after that, in 1984, the band worked with producer Bob Ezrin, and released Two Steps from the Move. Before this, McCoy had written most of the songs by himself, but for this album Bob Ezrin helped McCoy with the writing, along with Monroe. He also got some help with the lyrics from legendary Ian Hunter (of Mott The Hoople). After Razzle's death, Sam Yaffa left the band due to personal differences with McCoy (amongst other reasons he was now engaged to Anna, McCoy's former girlfriend known from the Oriental Beat cover). The band tried out new members (amongst them The Clash ex-drummer Terry Chimes and bassist René Berg), but things didn't work out, so the band disbanded in 1985.
