I want to know the answer to the following question:
What is Oklahoma's nickname?
All the background I'm provided with is that "It is also known informally by its nickname, The Sooner State, in reference to the non-Native settlers who staked their claims on the choicest pieces of land before the official opening date, and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory.". Is that enough to answer the question?
