How this entity was disambiguated
This entity first appeared as the object of triple T439549 — 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: breakup of Gondwana Context triple: [Antarctic Plate, formedBy, breakup of Gondwana]
-
A.
supercontinent Pannotia
Supercontinent Pannotia was a short-lived late Proterozoic landmass that assembled near the end of the Precambrian and preceded the formation of the better-known supercontinent Pangaea.
-
B.
supercontinent Rodinia
Rodinia was an ancient supercontinent that assembled during the Proterozoic Eon and existed before the later supercontinent Pangaea, profoundly influencing Earth’s early tectonic and climatic evolution.
-
C.
Deccan Traps volcanism
Deccan Traps volcanism refers to one of Earth’s largest known volcanic flood basalt events in western India, linked to mass extinction and major climatic changes near the end of the Cretaceous period.
-
D.
Himalayan orogeny
The Himalayan orogeny is the major mountain-building event resulting from the collision of the Indian and Eurasian tectonic plates, responsible for creating the Himalayan mountain range and the Tibetan Plateau.
-
E.
Caledonian orogeny
The Caledonian orogeny was a major Paleozoic mountain-building event that formed ranges across what are now Scandinavia, Scotland, Ireland, Greenland, and parts of North America as ancient continents collided.
- 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.
Instruction
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.
Input
Subject: breakup of Gondwana Description of subject: The breakup of Gondwana was a major tectonic event during the Mesozoic era in which the ancient southern supercontinent fragmented into the continents and oceanic plates of the Southern Hemisphere, reshaping global geography and climate.
