Suppose Angela Merkel is a German politician and scientist who served as the Chancellor of Germany from 2005 to 2021.

During her time as Chancellor, she faced challenges such as the European debt crisis and the migrant crisis.
Can we infer that "Angela Merkel served as the Chancellor of Germany from 1990 to 1995."? Yes, no, or maybe?
