Question: Who was the other finalist in the 1930 Allan Cup other than the team Roche was on? Passage:Roche was born in Prescott, Ontario, but moved to Montreal where he played junior hockey for the Montreal Victorias and other teams. He moved up to senior hockey for the Montreal Hockey Club and played for their Allan Cup-winning squad of 1930. He signed with the Maroons of the NHL, playing for the Maroons and the Windsor Bulldogs until 1933. He was released by the Maroons and signed with the Bruins in January 1933 only to be traded to the Senators one month later. In his one full season with the Senators in 1933–34 he showed a scoring touch, scoring 13 goals and 16 assists in 45 games. The next season, the Senators relocated to St. Louis to become the Eagles. Roche was traded twice in 1934–35; from St. Louis to Buffalo, then to the Red Wings. That marked his last season in the NHL, as he subsequently played for various minor-league pro teams until 1942.

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.

Question: Which Super Kings player who were ahead of Badree in team depth is the oldest? Passage:Badree first played for an overseas Twenty20 franchise in January 2013, when he played for the Khulna Royal Bengals in the 2013 Bangladesh Premier League (BPL) season. Later in the year, he signed with the Rajasthan Royals for the 2013 Indian Premier League (IPL), although he played only a single game (against the Delhi Daredevils). In the 2014 IPL auction, Badree was bought by the Chennai Super Kings for US$50,000. He went on to play four matches for the team during the 2014 season, but took only two wickets, with Ravichandran Ashwin and Ravi Jadeja being the preferred spin options. Later in 2014, Badree signed with the Brisbane Heat for the 2014–15 Big Bash League season in Australia. He was unable to play any matches due to a shoulder injury, but re-signed for the 2015–16 season. He struggled for form early in the season, going wicketless in his first three games, but eventually bounced back to finish as his team's leading wicket-taker, with nine wickets from eight matches. This included 5/22 in the final game of the season, against the Melbourne Stars.
