The two correct answers that describe evidence that led Dr. Semmelweis to conclude that childbed fever could be prevented with handwashing are:
- Far fewer women died during home and midwife births than during hospital births.
- Doctors at the hospital performed autopsies on women who had died in childbirth and then examined laboring women.
These observations contributed to Dr. Semmelweis's hypothesis that the transmission of infectious material from autopsies to patients was a significant factor in the spread of childbed fever, leading him to advocate for handwashing as a preventive measure.
