How this entity was disambiguated
This entity first appeared as the object of triple T1814609 — 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: Miller–Urey experiment Context triple: [Harold Urey, knownFor, Miller–Urey experiment]
-
A.
Haldane–Oparin hypothesis of the origin of life
The Haldane–Oparin hypothesis of the origin of life proposes that life first arose through a gradual chemical evolution of organic molecules in Earth’s early “primordial soup,” eventually leading to self-replicating systems.
-
B.
Luria–Delbrück experiment
The Luria–Delbrück experiment was a landmark 1943 study in bacterial genetics that demonstrated mutations arise randomly rather than in response to selective pressure, providing key evidence for the genetic basis of evolution.
-
C.
Cockcroft–Walton experiment
The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
-
D.
Meitner–Hahn experiments
The Meitner–Hahn experiments were pioneering nuclear physics investigations in the 1930s that led to the discovery and explanation of nuclear fission in uranium.
-
E.
Szostak Design
Szostak Design is an architectural firm known for designing prominent cultural and performing arts venues, including the Durham Performing Arts Center in North Carolina.
- 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.
