How are the subjects in the artworks of kathe kollwitz treated in an expressionist manner?

I believe the correct answer is: She emotionally addressed contemporary issues of social justice and of personal loss.

Käthe Kollwitz was a German artist, who worked with painting and sculpture and was the first woman admitted to Prussian Academy of Arts. Even though she was born during the epoch of Realism, her art is associated with Expressionism as she emotionally addressed contemporary issues of social justice and of personal loss. Her most famous art cycles, including The Weavers and The Peasant War, depict the effects of poverty, hunger, and war on the working class.
