Step-by-step explanation:
The example that fulfills the educational requirements for naturalization is being a graduate from an Oklahoma High School. As part of the eligibility criteria for naturalization, applicants are required to demonstrate an ability to read, write, and speak English. Graduating from a high school in the United States typically ensures that the individual has received an education in English, which satisfies this requirement. While graduating from prestigious universities or being a professor may demonstrate high levels of education, the key criterion for naturalization regarding education is the ability to use the English language and have knowledge of U.S. government and history, which is typically included in a U.S. high school curriculum.
