Which two sisters subsequently enrolled in Howard's College of Liberal Arts at the same time?

The answer identifying Lillie E. Burke and Beulah Elizabeth Burke as the two sisters who enrolled in Howard's College of Liberal Arts at the same time is correct because historical records indicate that both sisters pursued their education together at Howard University. This choice highlights the significance of familial connections and shared educational experiences among members of Alpha Kappa Alpha Sorority, showcasing the importance of sisterhood and collaboration in achieving academic goals.

The other options do not accurately represent the historical enrollment of sisters at Howard's College of Liberal Arts. Marjorie Hill, Anna Easter Brown, and Beulah Elizabeth Burke each had their own academic journeys, but the emphasis on Lillie and Beulah together underscores their unique bond as sisters and their simultaneous educational paths, which is a noteworthy aspect of their biographies in the context of the sorority's history.
