Phrase: Hirnantian glaciation | Statement: [Late Ordovician mass extinction, associatedWith, Hirnantian glaciation]

Target entity: Hirnantian glaciation
Context triple: [Late Ordovician mass extinction, associatedWith, Hirnantian glaciation]

• A. Sturtian glaciation
  The Sturtian glaciation was a major global ice age during the Neoproterozoic, when extensive ice sheets may have covered much of Earth’s surface in one of the most severe glacial events in the planet’s history.
• B. 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.
• C. 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.
• D. Kaigas glaciation
  The Kaigas glaciation was an early Neoproterozoic ice age event in Earth's history, preceding the more extensive Sturtian glaciation and representing one of the planet's significant pre-Cryogenian glacial episodes.
• 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. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Hirnantian glaciation
Triple: [Late Ordovician mass extinction, associatedWith, Hirnantian glaciation]

The Hirnantian glaciation was a major Late Ordovician ice age marked by extensive continental ice sheets and global cooling that played a key role in driving one of Earth’s largest mass extinction events.
