How this entity was disambiguated
This entity first appeared as the object of triple T13127242 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
Target entity: Pleistocene glaciation Context triple: [Lake Missoula basin, formedBy, Pleistocene glaciation]
-
A.
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.
-
B.
Saalian glaciation
The Saalian glaciation was a major Middle Pleistocene ice age in northern Europe, during which extensive ice sheets covered large parts of the continent.
-
C.
Last Glacial Period
The Last Glacial Period was the most recent major ice age, spanning roughly 115,000 to 11,700 years ago, during which large ice sheets covered vast areas of North America, Europe, and Asia and global climates were significantly colder and drier than today.
-
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.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Subject: Pleistocene glaciation Description of subject: Pleistocene glaciation refers to the series of extensive ice ages during the Pleistocene Epoch, when large ice sheets repeatedly advanced and retreated over vast areas of the Northern Hemisphere, dramatically reshaping landscapes and climates.
