premise: An Evening With Groucho is the title of a 1972 recording at New York City's Carnegie Hall of the last one-man show by American comedian Groucho Marx. Introduced by Dick Cavett, the show was released as a double album by A&M Records. Marx shared family stories and performed songs from Marx Brothers movies. Marvin Hamlisch accompanied Groucho on the piano.
hypothesis: An Evening with Groucho was recorded less than half a century ago
reason: My statement is definitely correct because if it was recorded half a century ago (50 years), it would mean the year would be 2022. Since we are in 2019, my statement that it was recorded less than half a century ago is correct. The system may not be able to tell how far a date is from now, when using more abstract terms for time.
