NER
Named-entity recognition
gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases).

Target entity: Pridoli–Lochkovian boundary Context triple: [Klonk Section, geologicTimeBoundary, Pridoli–Lochkovian boundary]
-
A.
Givetian–Frasnian boundary
The Givetian–Frasnian boundary marks the internationally recognized stratigraphic transition between the Middle and Late Devonian periods, defined by specific fossil and sedimentary changes in the geologic record.
-
B.
Emsian–Eifelian boundary
The Emsian–Eifelian boundary marks the internationally recognized transition between the Early and Middle Devonian periods in the geologic timescale.
-
C.
Frasnian–Famennian boundary
The Frasnian–Famennian boundary marks a major Late Devonian mass extinction interval characterized by severe global environmental upheavals and widespread marine biodiversity loss.
-
D.
Lochkovian Epoch
The Lochkovian Epoch is the earliest subdivision of the Devonian Period, marking a time of significant diversification in early fish and terrestrial ecosystems.
-
E.
Pridoli Epoch
chosen
The Pridoli Epoch is the final epoch of the Silurian Period, marking a transitional interval in Earth’s history just before the onset of the Devonian.
- F. None of above.
