premise: Vernon Deloss Walker (August 14, 1931 – April 19, 1996) was a notable advertising executive and political campaign consultant. Walker founded the Memphis, Tennessee-based advertising firm Walker + Associates, Inc. in October 1965. Walker played a major role in politics, corporate marketing and philanthropy throughout the South from the 1960s to 1990s.
hypothesis: Vernon Deloss Walker worked in the south for at least 25 years.
reason: My statement is definitely correct because Walker was working in the south from 1965 to the 1990's, so he has definitely been there for at least 25 years. I most likely fooled the system because I used a number that was not present in the paragraph.
