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: What was the age difference between the commodore and his brother? Passage:Samuel Shaw was a Revolutionary War naval officer who, along with Richard Marven, were the first whistleblowers of the infant United States. As a whistleblower, Shaw was instrumental in the Continental Congress' passage of the first whistleblower protection law in the United States. Shaw, a midshipman, and Marven, a third lieutenant in the Continental Navy, were moved to act after witnessing the torture of British prisoners of war by Commodore Esek Hopkins, then Commander-in-Chief of the Continental Navy. Shaw and Marven were both from Rhode Island, as was Hopkins, whose brother was Stephen Hopkins, Governor of the new state, and a signatory to the Declaration of Independence. For reporting the misconduct of the Navy's highest officer, Shaw and Marven were both dismissed from the Navy. Worse still, Hopkins then filed a criminal libel suit against Shaw and Marven in the Rhode Island Courts.

Q: Question: In what state was Bliss and Faville's most famous project built? Passage:Hart began his architectural career in Denver, finding work in 1898 as a draftsman for the firm of Willis A. Marean and Albert J. Norton, who later designed the Colorado Governor's Mansion (1908). In 1900, he joined Frank E. Edbrooke & Company, who had designed the Brown Palace Hotel (1892). By 1902, he had moved to California, where he spent a year drafting plans for new campus building of Stanford University, where conservative Richardsonian Romanesque detail adorned newly evolving California Mission Revival Style architecture under the guidance of Boston-based Shepley, Rutan & Coolidge. At Stanford, he was also exposed to the landscape architecture of Frederick Law Olmsted. He then spent a year working for the young firm of Meyer and O'Brien before joining the firm of Bliss and Faville just in time to work on their most famous project, the St. Francis Hotel, and other major buildings arising from the ashes of the San Francisco earthquake of 1906, including the Neoclassical architecture of the Bank of California and the more Beaux-Arts style of the Union Savings Bank (1909), the Columbia (now Geary) Theater (1909), and the Masonic Temple (1912).
