Target entity: Eocene–Oligocene boundary event
Context triple: [Eocene–Oligocene climate transition, alsoKnownAs, Eocene–Oligocene boundary event]
  • 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. Great Ordovician Biodiversification Event
    The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
  • C. Cretaceous–Paleogene boundary
    The Cretaceous–Paleogene boundary marks the geological transition 66 million years ago associated with a mass extinction event that wiped out non-avian dinosaurs and many other species, likely triggered by a large asteroid impact.
  • D. Toarcian Oceanic Anoxic Event
    The Toarcian Oceanic Anoxic Event was a major Early Jurassic global environmental crisis marked by widespread marine oxygen depletion, significant carbon-cycle disruption, and associated mass extinctions.
  • 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.
