Phrase: Eifelian Stage | Statement: [Emsian–Eifelian boundary, separates, Eifelian Stage]

Target entity: Eifelian Stage
Context triple: [Emsian–Eifelian boundary, separates, Eifelian Stage]

• A. Emsian Stage
  The Emsian Stage is a division of the Early Devonian epoch characterized by distinctive marine fossil assemblages and sedimentary deposits used to correlate rock layers worldwide.
• B. Asselian Stage
  The Asselian Stage is the earliest stage of the Permian Period, marking the transition from the Carboniferous and characterized by distinctive marine and terrestrial fossil assemblages used for global stratigraphic correlation.
• C. Darriwilian Stage
  The Darriwilian Stage is a division of the Ordovician Period marked by significant diversification of marine life and used globally to date and correlate Middle Ordovician rock strata.
• D. Famennian stage
  The Famennian stage is the final stage of the Late Devonian Period, marked by significant evolutionary turnover and recovery following major extinction events.
• E. Aquitanian Stage
  The Aquitanian Stage is the earliest age of the Miocene Epoch, marking a distinct interval in Earth’s geologic time characterized by significant climatic and faunal transitions.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
