Target entity: Mesoproterozoic Era
Context triple: [Proterozoic Eon, subdivision, Mesoproterozoic Era]
  • A. Paleoproterozoic Era
    The Paleoproterozoic Era was an early division of Earth's history marked by the stabilization of continental cratons, widespread banded iron formations, and the Great Oxidation Event that significantly increased atmospheric oxygen.
  • B. 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.
  • C. Archean Eon
    The Archean Eon is an ancient geological eon of Earth's history, spanning from about 4.0 to 2.5 billion years ago, characterized by the formation of the first stable continental crust and the earliest known life.
  • D. 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.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
