Example Input: Question: Was Vermont's GDP larger than Massachusetts' GDP the year Coolidge was born? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.
