Final answer:
The 1,000-year interval between the original Babylonian Empire, which began around 1800 BCE, and the Neo-Babylonian Empire of the late 7th century BCE is best represented by the year 2000 B.C.E.
Step-by-step explanation:
The Babylonian Empire is a significant subject of ancient history. The original Babylonians are known for their early civilization, particularly under the reign of King Hammurabi from approximately 1792 to 1750 BCE. After a considerable period, marked by the rule of other groups such as the Kassites and the Assyrians, a resurgence known as the Neo-Babylonian Empire occurred in the late 7th century BCE. This empire was a revival of Babylonian power and culture, flourishing until the Persian conquest in the 6th century BCE. Looking at the historical timeline provided, the interval between the older Babylonian civilization, starting around 1800 BCE, and the rise of the Neo-Babylonian empire in the late 7th century BCE is over 1,000 years. Therefore, the option that best represents the 1,000-year interval between the Babylonian and Neo-Babylonian empires is D) 2000 B.C.E.
