Phrase: Precambrian Supereon | Statement: [Proterozoic Eon, partOf, Precambrian Supereon]

Target entity: Precambrian Supereon
Context triple: [Proterozoic Eon, partOf, Precambrian Supereon]

• A. Proterozoic Eon
  The Proterozoic Eon is a major division of Precambrian time, spanning from about 2.5 billion to 541 million years ago, marked by the buildup of atmospheric oxygen, the emergence of complex single-celled and early multicellular life, and the assembly of large continental landmasses.
• B. Paleozoic Era
  The Paleozoic Era was an ancient geologic time interval, spanning roughly 541 to 252 million years ago, marked by the emergence and diversification of complex life in the seas and on land and the assembly of major continental landmasses.
• C. Phanerozoic Eon
  The Phanerozoic Eon is the current and most recent major division of Earth's history, marked by abundant fossil evidence and the evolution and diversification of complex life forms, including plants, animals, and eventually humans.
• D. Early Devonian
  The Early Devonian was the initial subdivision of the Devonian Period, marked by the diversification of early fishes and the spread of primitive vascular land plants across emerging terrestrial ecosystems.
• E. Jurassic Period
  The Jurassic Period was a major division of the Mesozoic Era characterized by warm climates, the dominance and diversification of dinosaurs, and the early evolution of birds.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Precambrian Supereon
Triple: [Proterozoic Eon, partOf, Precambrian Supereon]

The Precambrian Supereon is the vast span of Earth's early history before the Phanerozoic, encompassing the Hadean, Archean, and Proterozoic eons during which the planet formed, life first appeared, and early continents and atmospheres developed.
