Which of the following was NOT an election year?

An election year is one in which all four numbers are evenly divided by four (1944, 1940, etc. ). Since 1840, American presidents elected in years ending in zero have been destined to die in office. William H. Harrison, the man who served the shortest term, died of pneumonia several weeks after his inauguration. Abraham Lincoln was one of the four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James A. Garfield, a former Union Army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn’t give a job. While in his second term of office (1901), William Mckinley, another Ohioan, attended the Pan-American Exposition at Baffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. Three years later after his election in 1920, Warren G. Harding died in office. Although it was never proved, many believe he was poisoned. Franklin D. Roosevelt had been elected four times(1912, 1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and died of the illness in 1945. John F. Kennedy, the last of the line, was assassinated in 1963, only three years after his election.
