Final answer:
Mary, living in Washington D.C. in 1962, would not have been able to vote in the presidential election as D.C. residents were only granted the right to vote in presidential elections starting in 1964 following the ratification of the Twenty-Third Amendment.
Step-by-step explanation:
The question pertains to whether a woman named Mary living in Washington D.C. in 1962 would be able to vote in a presidential election. The answer is that, unfortunately, Mary would not have been able to vote for the president in 1962.
While women in the United States were granted the right to vote in 1920 through the Nineteenth Amendment, residents of Washington D.C. did not have the right to vote in presidential elections until the ratification of the Twenty-Third Amendment in 1961. However, the first presidential election in which D.C. residents could participate was in 1964, meaning Mary would have to wait until the next election cycle to cast her vote for president.
