NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Eocene–Oligocene climate transition
Context triple: [Cenozoic glaciations, significantEvent, Eocene–Oligocene climate transition]
  • A. Eocene–Oligocene climate transition chosen
    The Eocene–Oligocene climate transition was a major global cooling event around 34 million years ago that marked the shift from a greenhouse to an icehouse Earth, including the formation of large Antarctic ice sheets.
  • B. Paleogene climatic optimums
    Paleogene climatic optimums were intervals of exceptionally warm global climate during the Paleogene Period that set the stage for the cooler conditions of the subsequent Neogene.
  • C. Snowball Earth glaciations
    Snowball Earth glaciations were extreme global-scale ice ages in the Precambrian when ice sheets may have covered most or all of Earth’s surface for millions of years.
  • D. Cenozoic glaciations
    Cenozoic glaciations are a series of major ice age cycles during the Cenozoic Era that saw extensive growth and retreat of continental ice sheets, profoundly shaping Earth’s climate and landscapes.
  • E. Lomagundi–Jatuli carbon isotope excursion
    The Lomagundi–Jatuli carbon isotope excursion was a major global perturbation in the carbon cycle during the Paleoproterozoic, marked by unusually high carbon isotope ratios that suggest prolonged burial of organic carbon and significant changes in Earth’s atmosphere and oceans.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
