{ "releaseId": "terra-geobenchx-v1", "taskId": "365343", "question": "How many rivers flow through areas with significant forest coverage in South America?", "submittedPrompt": "How many rivers flow through areas with significant forest coverage in South America?\n\nTask conventions: Use the released reference's country-level definition: South American countries (CONTINENT='South America') with World Bank 2021 forest area strictly greater than 50 percent of land area. Join original ISO_A3 to Country Code, not fuzzy names. Count distinct original FAO river records intersecting those polygons, including boundary touches. A record can meet several countries but counts once; these are river segments, not unique named whole rivers. National forest percentage is NOT a map of actual forest along a river. Keep unknown/missing indicator countries explicit; unknown_count is the number of river records that intersect an unknown eligible country and no qualifying known country, plus invalid/missing river geometries. Use the original frozen data, no live substitution. This is internal research; FAO-derived outputs are not cleared for promotional publication.\n\n\n\nReturn the original selected river features with benchmark_row_id, attributes and unchanged geometry. Map optional. Finish with fenced JSON {count:integer,unknown_count:integer,coverage_note:string,selection:{collectionId,itemId,assetKey}}. Explain the country-level proxy, 2021 year and segment-count unit.\n\nDelivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs. This replaces the JSON-code-block formatting requirement above. Blue attaches your explicit selection to the accepted final answer.
