Phrase: Silurian–Devonian boundary | Statement: [Klonk Section, defines, Silurian–Devonian boundary]

Target entity: Silurian–Devonian boundary
Context triple: [Klonk Section, defines, Silurian–Devonian boundary]

• A. Emsian–Eifelian boundary
  The Emsian–Eifelian boundary marks the internationally recognized transition between the Early and Middle Devonian periods in the geologic timescale.
• B. 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.
• C. Carboniferous–Permian boundary
  The Carboniferous–Permian boundary marks the internationally recognized transition between the late Paleozoic Carboniferous and Permian periods, defined stratigraphically by a Global Boundary Stratotype Section and Point (GSSP).
• D. 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.
• E. Devonian Period
  The Devonian Period was a division of the Paleozoic Era characterized by the diversification of fish, the first significant colonization of land by plants and early tetrapods, and major reef-building in the oceans.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
