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). For disambiguation, the statement where the phrase occurs as object is also given. 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: passive margin of Gondwana | Statement: [Avalonia microcontinent, tectonicSettingDuringRift, passive margin of Gondwana]

Target entity: passive margin of Gondwana
Context triple: [Avalonia microcontinent, tectonicSettingDuringRift, passive margin of Gondwana]

• A. Atlantic passive margin
  The Atlantic passive margin is a tectonically quiet continental edge along the Atlantic Ocean characterized by broad continental shelves, thick sedimentary deposits, and a lack of major active plate boundaries or significant seismic and volcanic activity.
• B. breakup of Gondwana
  The breakup of Gondwana was a major tectonic event during the Mesozoic era in which the ancient southern supercontinent fragmented into the continents and oceanic plates of the Southern Hemisphere, reshaping global geography and climate.
• C. Eurasian continental margin
  The Eurasian continental margin is the submerged edge of the Eurasian tectonic plate, extending from its coastal shelves into the deep Arctic and Atlantic oceans and encompassing features such as the Chukchi Plateau.
• D. West Antarctic Rift System
  The West Antarctic Rift System is a major tectonic rift zone underlying much of West Antarctica, characterized by crustal extension, volcanism, and significant influence on the region’s topography and ice sheet dynamics.
• E. Gondwana
  Gondwana was a vast ancient supercontinent in the Southern Hemisphere that included present-day South America, Africa, Antarctica, Australia, the Indian subcontinent, and the Arabian Peninsula.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: passive margin of Gondwana
Triple: [Avalonia microcontinent, tectonicSettingDuringRift, passive margin of Gondwana]

The passive margin of Gondwana was the long, tectonically quiet continental edge of the ancient supercontinent Gondwana, where thick sedimentary sequences accumulated and from which various microcontinents, such as Avalonia, later rifted away.
