Which two themes are found in Susan Glaspell's "A Jury of Her Peers"?

Adapted from Susan Glaspell’s popular one-act play, Trifles (1920), "A Jury of Her Peers" is about sisterhood. Women’s roles as wives, mothers, and homemakers do not make them totally passive, unintelligent, or subordinate to men. Mrs. Peters, for example, being small, thin, and soft-spoken, did not strike Martha Hale as a sheriff’s wife when they first met; however, Mrs. Peters reveals her inner strength in defying her husband by suppressing evidence that would surely convict Minnie Wright of murder. Because they understand how John’s killing the canary must have been the last straw in killing his wife’s love of life, Martha and Mrs. Peters "knot" the criminal investigation. They shift their loyalty from their husbands, and the male-dominated legal system, to a woman who mirrors their own lives. As Martha wistfully says of her regret in abandoning her neighbor Minnie, "We live close together, and we live far apart. We all go through the same things-it’s all just a different kind of same thing!" Because the legal defense of justifiable homicide by an abused wife might not have succeeded in the early twentieth century, the women take matters into their own hands.
