Legend has it that the game of baseball was invented in 1839 in Cooperstown, New York (home of the National Baseball Hall of Fame), by a man named Abner Doubleday, who would later go on to be a general in the Civil War. A significant amount of evidence suggests that the game was not invented by Doubleday, however, but instead evolved from a game played in England as far back as the 18th century. Noah plans to write a research paper addressing this controversy. Which keywords are MOST likely to help Noah locate relevantinformation?
a. Doubleday, baseball
b. 18th century, England
c. Civil War, 1839
d. Cooperstown, baseball
