premise: Michael Tunn (born 18 January 1974) is an Australian radio announcer and television presenter. He was hired by Australia's national youth station Triple J in 1990 at the age of 17, making him Australia's youngest professional radio presenter at the time.
hypothesis: Michael Tunn was hired by Australia's national youth station Triple J 13 years after he was born.
reason: He was hired when he was 17, so it's definitely incorrect. It's difficult because it requires looking at multiple parts of the text and is somewhat complex I guess.
