NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Weichselian glaciation
Context triple: [Fennoscandian Ice Sheet, majorGlaciation, Weichselian glaciation]
  • A. 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.
  • B. Würm glaciation chosen
    The Würm glaciation was the last major glacial period of the Pleistocene in the Alps, marked by extensive ice coverage and shaping much of the region’s modern landscape.
  • C. Last Glacial Maximum
    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.
  • D. 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.
  • E. Marinoan glaciation
    The Marinoan glaciation was a major Neoproterozoic ice age, likely a global or near-global “Snowball Earth” event that occurred around 650–635 million years ago.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
