Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Emsian–Eifelian boundary | Statement: [Middle Devonian, startBoundary, Emsian–Eifelian boundary]

Target entity: Emsian–Eifelian boundary
Context triple: [Middle Devonian, startBoundary, Emsian–Eifelian boundary]

• A. Furongian
  Furongian is the late epoch of the Cambrian Period, marking the final stage of early Paleozoic marine life diversification before the Ordovician.
• B. Late Devonian
  The Late Devonian was the final epoch of the Devonian Period, marked by extensive reef collapse, major evolutionary changes in fish and early land plants, and several significant mass extinction events.
• C. Late Ordovician
  The Late Ordovician was the final subdivision of the Ordovician Period, marked by extensive marine biodiversity followed by one of the largest mass extinction events in Earth's history.
• D. Cisuralian Epoch
  The Cisuralian Epoch is the earliest subdivision of the Permian, marking a time of significant diversification of terrestrial life and continued development of early amniotes following the late Paleozoic ice age.
• E. Hettangian stage
  The Hettangian stage is the earliest age of the Jurassic Period, marking the beginning of the Mesozoic era’s Jurassic system in the geologic time scale.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
