Phrase: Pleistocene epoch | Statement: [Cordilleran Ice Sheet, geologicTimePeriod, Pleistocene epoch]

Target entity: Pleistocene epoch
Context triple: [Cordilleran Ice Sheet, geologicTimePeriod, Pleistocene epoch]

• A. Pleistocene epoch chosen
  The Pleistocene epoch was a geological time period characterized by repeated ice ages, widespread glaciation, and the evolution and global spread of modern humans.
• B. Quaternary period
  The Quaternary period is the most recent division of geologic time, characterized by repeated ice ages, the evolution and global spread of modern humans, and significant climatic fluctuations over the last 2.6 million years.
• C. Last Glacial Period
  The Last Glacial Period was the most recent major ice age, spanning roughly 115,000 to 11,700 years ago, during which large ice sheets covered vast areas of North America, Europe, and Asia and global climates were significantly colder and drier than today.
• D. Pliocene epoch
  The Pliocene epoch was a geological time period roughly 5.3 to 2.6 million years ago marked by cooler global climates, the expansion of grasslands, and significant evolutionary developments among mammals and early hominins.
• E. Pridoli Epoch
  The Pridoli Epoch is the final epoch of the Silurian Period, marking a transitional interval in Earth’s history just before the onset of the Devonian.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
