Phrase: Cryogenian Period | Statement: [Neoproterozoic Era, contains, Cryogenian Period]

Target entity: Cryogenian Period
Context triple: [Neoproterozoic Era, contains, Cryogenian Period]

• A. Neoproterozoic Era
  The Neoproterozoic Era was the final era of the Proterozoic Eon, marked by global “Snowball Earth” glaciations and the emergence of early multicellular life leading up to the Cambrian explosion.
• B. Ediacaran Period
  The Ediacaran Period was a late Precambrian geological interval, roughly 635–541 million years ago, marked by the emergence of some of the earliest large, complex multicellular life forms.
• C. 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.
• D. Rhyacian Period
  The Rhyacian Period is a geologic time interval in the early Proterozoic characterized by significant crustal growth, widespread metamorphism, and some of the earliest known large-scale glaciations.
• E. Huronian glaciation
  The Huronian glaciation was one of Earth's earliest and longest ice ages, occurring over 2.4 billion years ago and likely linked to the Great Oxidation Event and major climatic shifts.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Cryogenian Period
Triple: [Neoproterozoic Era, contains, Cryogenian Period]

The Cryogenian Period was a time in Earth's history roughly 720–635 million years ago characterized by some of the most extensive global glaciations, when ice sheets may have covered much of the planet.
