-
B.
Nematoda
Nematoda is a diverse phylum of elongated, unsegmented roundworms found in nearly every habitat on Earth, many of which are important parasites of plants, animals, and humans.
-
C.
Rotifera
Rotifera is a phylum of microscopic, mostly aquatic invertebrates known for their wheel-like ciliated structures used for feeding and locomotion.
-
D.
Danio rerio
Danio rerio, commonly known as the zebrafish, is a small freshwater fish widely used as a model organism in biological and medical research.
-
E.
Ascaris lumbricoides
Ascaris lumbricoides is a large parasitic roundworm that infects the human intestine and is a common cause of ascariasis worldwide.
- 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: Caenorhabditis Description of subject: Caenorhabditis is a genus of small, free-living nematode worms widely used as model organisms in biological and genetic research.
