Answer
Brief Explanations:
Lázaro Cárdenas nationalized Mexico's oil industry in 1938 mainly to have the country directly benefit from its oil resources. This was a move to assert national sovereignty over a key economic asset and gain economic control and revenue for the nation, rather than having foreign - owned companies reap most of the profits. It was not primarily about curtailing foreign investment just for the sake of it, ending corruption in private oil businesses (though corruption could have been a secondary consideration), or environmental protection.
Answer:
enable the country to get direct benefit from its vast supplies.
