Question: In brief, there is disagreement among historical analysts as to the exact time period when the minority leadership emerged officially as a party position. Nonetheless, it seems safe to conclude that the position emerged during the latter part of the 19th century, a period of strong party organization and professional politicians. This era was "marked by strong partisan attachments, resilient patronage-based party organizations, and...high levels of party voting in Congress." Plainly, these were conditions conducive to the establishment of a more highly differentiated House leadership structure.
Try to answer this question if possible: Is there a consensus about the time that minority leadership officially emerged as a position?
Answer: there is disagreement among historical analysts

Question: The character of New York's large residential districts is often defined by the elegant brownstone rowhouses and townhouses and shabby tenements that were built during a period of rapid expansion from 1870 to 1930. In contrast, New York City also has neighborhoods that are less densely populated and feature free-standing dwellings. In neighborhoods such as Riverdale (in the Bronx), Ditmas Park (in Brooklyn), and Douglaston (in Queens), large single-family homes are common in various architectural styles such as Tudor Revival and Victorian.

Question: The Sumerian city-states rose to power during the prehistoric Ubaid and Uruk periods. Sumerian written history reaches back to the 27th century BC and before, but the historical record remains obscure until the Early Dynastic III period, c. the 23rd century BC, when a now deciphered syllabary writing system was developed, which has allowed archaeologists to read contemporary records and inscriptions. Classical Sumer ends with the rise of the Akkadian Empire in the 23rd century BC. Following the Gutian period, there is a brief Sumerian Renaissance in the 21st century BC, cut short in the 20th century BC by Semitic Amorite invasions. The Amorite "dynasty of Isin" persisted until c. 1700 BC, when Mesopotamia was united under Babylonian rule. The Sumerians were eventually absorbed into the Akkadian (Assyro-Babylonian) population.
Try to answer this question if possible: When does Classical Sumer end?
Answer:
rise of the Akkadian Empire
