[EX 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 Indiaof 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.

[EX Q]: Question: Which president saw the establishment of the recreation area that contains the lower of the San Juan River? Passage:From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing very briefly back into southwest Colorado (within half a mile (0.8km) of the Four Corners quadripoint) before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons, often over in depth. The lower of the San Juan River, in a remote portion of the Glen Canyon National Recreation Area, are flooded by Lake Powell, which is formed by Glen Canyon Dam on the Colorado River. The San Juan joins the Colorado in San Juan County, Utah at a point about to the north of Navajo Mountain and northeast of Page, Arizona.

[EX Q]: Question: How many years had the Western Australia cricket team been in existence for the year Millar was born? Passage:Geoffrey Alan Millar (born 22 November 1955) is a former Australian cricketer who played several matches for Western Australia during the early 1980s. From Perth, Millar played at colts level during the late 1970s, generally as an all-rounder. He made his Sheffield Shield debut for Western Australia during the 198182 competition, and failed to take a wicket in what was to be his only first-class match. In the match, against Queensland at the WACA Ground in February 1982, he was part of a pace attack that included David Boyd (who he opened the bowling with in the first innings), Mick Malone, and Ken MacLeay. Millar also appeared at List A level several times for Western Australia. In his first match, the third-place playoff of the 198182 McDonald's Cup, he took 2/17 and scored 30 runs, and was thus named man of the match. His two further matches both occurred in the following year's tournament. At grade cricket level, Millar played 177 matches for the Mount Lawley District Cricket Club.
