premise: Patricia Donoho Hughes (August 18, 1930 – January 20, 2010) was a First Lady of Maryland, married to former Maryland Governor Harry Hughes. She was educated at Sorbonne (1949) and Bryn Mawr College (1951) before getting married on June 30, 1951. She later continued her education at the University of Delaware (1966). Mrs. Hughes was a teacher and educator by profession.
hypothesis: Patricia Donoho Hughes continued her education until she was 36 years old.
reason: Patricia Donoho Hughes finished her education in 1966, which would put her age at 36 if she was born in 1930. This may have been difficult because it appears that in the paranthesis is the year in which education was completed for each school listing, but this is not easy to see.
