premise: Anna Katharina Wienhard (born 1977) is a German mathematician whose research concerns differential geometry, and especially the use of higher Teichmüller spaces to study the deformation theory of symmetric geometric structures. She is a professor at Heidelberg University.
hypothesis: Anna Katharina Wienhard lectures in front of students in order to help them learn
reason: My statement is definitely correct because the statement indicates she is a professor, and professors give lectures in class. These lectures help students learn. Maybe it was difficult for the system because I used different phrases for teaching.
