The two correct answers that describe evidence leading Dr. Semmelweis to conclude that childbed fever could be prevented with handwashing are:
c. Doctors at the hospital performed autopsies on women who had died in childbirth and then examined laboring women.
e. Far fewer women died during home and midwife births than during hospital births.
These details contributed to his realization that there was a connection between doctors' practices and the spread of infection, leading him to advocate for handwashing to reduce mortality rates.
