Triple

Target entity: Precambrian
Context triple: [Grampian Group, geologicalPeriod, Precambrian]

• A. Precambrian Supereon chosen
  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.
• 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. 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.
• E. Eoarchean Era
  The Eoarchean Era is an ancient division of Earth's early history marked by the formation of the first stable continental crust and some of the oldest known rocks and possible signs of early life.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
