{ "releaseId": "terra-geobenchx-v1", "taskId": "130168", "question": "How many mineral extraction facilities in Africa are located in countries with negative net migration?", "submittedPrompt": "How many mineral extraction facilities in Africa are located in countries with negative net migration?\n\nTask conventions: Use 2023 net migration and countries classified as Africa in the provided boundaries. Count source facility records once, retaining benchmark_row_id; repeated FeatureUID values are not a deduplication instruction. Use point-within-polygon membership (boundary points are excluded). Resolve country identity using the supplied fields; differing country-name spellings are not evidence that migration data is missing. Report any records in countries with unresolved migration as unknown. Offshore or otherwise outside-country points do not satisfy within.\n\n\n\nCompute the answer using only the supplied immutable fixtures. Save the selected features with their benchmark_row_id and original geometry as an inspectable data artifact. In your accepted final answer include one JSON code block with count (integer), unknown_count (integer), coverage_note (string), and selection (an object with collectionId, itemId, assetKey for that artifact). Maps are optional. Do not request clarification: the task conventions are fixed. Do not use live substitutes, shrink the study question, or use external benchmark answers.\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. Finish with a concise ordinary-language answer agreeing with that selected result; do not duplicate the JSON in chat.\n\nSupplied immutable inputs:\n[\n {\n \"name\": \"African mineral extraction facilities\",\n \"edition\": \"USGS 2021 benchmark snapshot\",\n \"units\": {},\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"World Bank country boundaries\",\n \"edition\": \"GeoBenchX harmonized names\",\n \"units\": {},\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"Net migration, World Development Indicators\",\n \"edition\": \"2024-11-13 snapshot; use 2023\",\n \"units\": {\n \"2023\": \"people (net migration)\"\n },\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n }\n]", "finalAnswer": "I found 1,642 mineral extraction facility records in Africa that are strictly within an African country polygon and in countries with negative 2023 net migration.
