premise: The 1974 Atlanta Braves season was the ninth season in Atlanta along with the 104th season as a franchise overall. The team finished third in the National League West with a record of 88–74, 14 games behind the Los Angeles Dodgers. During the season, Braves outfielder Hank Aaron became the all-time career leader in home runs, surpassing Babe Ruth.
hypothesis: The Atlanta Braves began playing in Atlanta in 1973.
reason: This is definitely incorrect because the text said 1974 was the Braves' ninth season in Atlanta, so they would have played in Atlanta before 1973.  I think this was difficult because of the math involved.
