How this entity was disambiguated
This entity first appeared as the object of triple T5272363 — 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: Pratt & Whitney JT10D (cancelled successor project) Context triple: [Pratt & Whitney JT8D, successor, Pratt & Whitney JT10D (cancelled successor project)]
-
A.
Pratt & Whitney JT9D
The Pratt & Whitney JT9D is a high-bypass turbofan jet engine that powered early wide-body airliners and was notably used on the original Boeing 747 series.
-
B.
Pratt & Whitney JT3D
The Pratt & Whitney JT3D is an early low-bypass turbofan jet engine widely used on first-generation jet airliners such as the Boeing 707 and Douglas DC-8.
-
C.
Pratt & Whitney JT8D
The Pratt & Whitney JT8D is a low-bypass turbofan jet engine widely used on early short- to medium-range airliners and known for powering many classic narrow-body aircraft of the 1960s–1980s.
-
D.
Pratt & Whitney J58
The Pratt & Whitney J58 is a high-performance turbojet/ramjet hybrid engine developed for sustained high-speed, high-altitude flight, most famously powering the SR-71 Blackbird reconnaissance aircraft.
-
E.
Pratt & Whitney J57
The Pratt & Whitney J57 is a pioneering American axial-flow turbojet engine widely used in early Cold War military aircraft and notable as one of the first jet engines to produce over 10,000 pounds of thrust.
- 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: Pratt & Whitney JT10D (cancelled successor project) Description of subject: The Pratt & Whitney JT10D was a proposed but ultimately cancelled high-bypass turbofan engine project intended to modernize and replace the widely used JT8D series.
