Task: Question Answering
Input (English): Passage: In Ancient Egypt the Bronze Age begins in the Protodynastic period, c. 3150 BC. The archaic early Bronze Age of Egypt, known as the Early Dynastic Period of Egypt, immediately follows the unification of Lower and Upper Egypt, c. 3100 BC. It is generally taken to include the First and Second Dynasties, lasting from the Protodynastic Period of Egypt until about 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king. Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilization, such as art, architecture and many aspects of religion, took shape during the Early Dynastic period. Memphis in the Early Bronze Age was the largest city of the time.The Old Kingdom of the regional Bronze Age is the name given to the period in the 3rd millennium BC when Egypt attained its first continuous peak of civilization in complexity and achievement - the first of three "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley . The First Intermediate Period of Egypt, often described as a "dark period" in ancient Egyptian history, spanned about 100 years after the end of the Old Kingdom from about 2181 to 2055 BC. Very little monumental evidence survives from this period, especially from the early part of it. The First Intermediate Period was a dynamic time when the rule of Egypt was roughly divided between two competing power bases: Heracleopolis in Lower Egypt and Thebes in Upper Egypt. These two kingdoms would eventually come into conflict, with the Theban kings conquering the north, resulting in the reunification of Egypt under a single ruler during the second part of the 11th Dynasty. 
Question: How many years passed from the beginning of the Old Kingdom until the Protodynastic Period of Egypt?
