[Q]: 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.

[Q]: Question: Which of the two pitchers who combined to pitch three shutout innings had the most career no hitters? Passage:The Indians struck first off Marcus Stroman when Carlos Santana drew a leadoff walk in the first and scored on Mike Napoli's two out double, but their starter, Trevor Bauer had to leave the game in the bottom of the inning after allowing two walks and throwing 21 pitches due to a bloody pinkie finger as a result of being cut from a drone a few days earlier. Dan Otero in relief allowed a game-tying home run to Michael Saunders in the second. Napoli's home run in the fourth put the Indians back on top 2−1, but the Blue Jays tied it in the fifth off Zach McAllister when Ezequiel Carrera hit a leadoff triple and scored on Ryan Goins's groundout. Jason Kipnis's leadoff home run in the sixth gave the Indians a 3−2 lead. Stroman was taken out after walking Napoli with one out. Napoli moved to second on a wild pitch by reliever Joe Biagini and scored on José Ramírez's single to make it 4−2 Indians. Cody Allen and Andrew Miller combined to pitch three shutout innings, striking out five batters as the Indians took a 3–0 series lead.

[Q]: Question: Does Theodore Perry have any children? Passage:The T.B. Perry House is a historical residence located in Albia, Iowa, United States. Theodore Perry was a local attorney and businessman who served two terms in the Iowa Senate. He is also responsible for a couple of buildings in the Albia Square and Central Commercial Historic District. This house is a High Victorian eclectic style structure. It is one of four large brick houses in Albia known as the Four Sisters. They all feature a running brick bond on their exterior walls. It is an unusual architectural feature for southern Iowa in the period they were built, and it also suggests they have the same architect and/or brick mason. The Elbert-Bates House is another house in this group. The Perry house was designed by Charles A. Dunham from the prominent Burlington, Iowa architectural firm of Dunham & Jordan. It is noteworthy for its elaborate roofing system. It features five dormer windows, two hip-and-deck roofs, three gable roofs, and two hipped roofs. The steeply pitched roof also has finials, pendants, and brackets with a modified frieze under the eaves. Other elements of the richly ornamented exterior include barge boards on the second story and entry gables, and a front porch with Gothic tracery millwork. The house was listed on the National Register of Historic Places in 1983.
