premise: Andreas Wolfsgruber (born 1962, Salzburg, Austria) is an Austrian car designer and, since 2000, Head of the Magna Steyr Design Department. Between 1997 - 2000 he was engaged as a Lecturer at the Fh Joanneum Graz – Degree Programme „Industrial Management“.
hypothesis: Andreas Wolfsgruber lectured and was the Head of the Magna Steyr Design Department at the same time in 2000.
reason: The text has an overlap in 2000 between the two jobs, but it's unclear if that means he did them at the same time or if he stopped one and then started the other one all in the same year. The system saw both have 2000 and assumed they both happened at the same time.
