Kekayaan negara itu didapat dari produksi minyak buminya.

English Translation

That country’s wealth comes from its oil.

Clozemaster, please change the English translation from “its oil” to “its crude oil”.
“Minyak” includes petroleum, oil from palm trees etc., and aroma oil.
The cloze-word is {{buminya}} and “bumi” means “earth” or “ground/soil”.
We cannot fill in the blanked {{buminya}} by reading the English “its oil”.
