In the crucible when did Danforth hear Elizabeth is pregnant and what does he allow?

In the play "The Crucible" by Arthur Miller, Danforth hears that Elizabeth Proctor is pregnant during Act Four. Upon learning of her pregnancy, Danforth allows Elizabeth to be placed under house arrest instead of being imprisoned in the jail. This decision was made in an effort to protect the unborn child and ensure it is born in a safe and secure environment. Danforth understands the significance of her pregnancy and acknowledges that she should not be subjected to the harsh conditions of the jail.

By granting house arrest, Danforth demonstrates a degree of compassion and sensitivity in his role as a judge. He recognizes the exceptional circumstances surrounding Elizabeth's situation and makes an exception to the usual course of action taken with prisoners.
