Final answer:
The individual in question, who completed academic requirements for a PhD at Harvard but was never awarded it is not named among the options provided. W.E.B. Du Bois, who did complete his PhD at Harvard is known to have received his degree making 'None of the above' the correct answer.
Step-by-step explanation:
The individual who completed all of the academic requirements for a PhD at Harvard but was never 'in worded' it is not explicitly mentioned among the options provided. However, from the reference information given, we know that W.E.B. Du Bois did complete his PhD at Harvard, becoming the first African American to earn a PhD from Harvard University. This notable achievement indicates that Du Bois was awarded his PhD; thus, none of the options (John, Mary, Robert) fit the criteria.
With the information at hand, None of the above would be the accurate answer since Du Bois did receive his degree, and the other individuals mentioned are not relevant to the question. Furthermore, the reference mentions another individual, Stephen Ell, who received his Master's degree and PhD from the University of Chicago, not Harvard. Therefore, he is also not relevant to answering this question.
