Target entity: Last Glacial Maximum
Context triple: [Wisconsin glaciation, maximumIceExtentReached, Last Glacial Maximum]
  • A. Last Glacial Maximum chosen
    The Last Glacial Maximum was the most recent period in Earth’s history when ice sheets reached their greatest extent, dramatically lowering sea levels and reshaping global climates and ecosystems.
  • B. Holocene climatic optimum
    The Holocene climatic optimum was a warm period roughly 9,000–5,000 years ago when global temperatures, especially in the Northern Hemisphere, were higher than today, influencing the spread of forests and early human civilizations.
  • C. Pleistocene epoch
    The Pleistocene epoch was a geological time period characterized by repeated ice ages, widespread glaciation, and the evolution and global spread of modern humans.
  • D. Little Ice Age
    The Little Ice Age was a period of cooler global temperatures and glacial expansion, roughly from the 14th to the mid-19th century, that significantly affected climate, agriculture, and societies, especially in the Northern Hemisphere.
  • E. Gaskiers glaciation
    Gaskiers glaciation was a brief but intense Neoproterozoic ice age, occurring around 580 million years ago, that is associated with widespread glacial deposits and may have influenced early animal evolution.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
