Well, the assignment about the story of Ignaz Semmelweis is over. Thank you for participating (to those who have participated, obviously).
There is not a single solution to the activity or, better said, there are many little nuances and several ways of understanding some of the pieces of information in Semmelweis' research.
That said, HERE it is my proposal for an accurate solution to the task. Of course, it follows the list of steps as explained in class.
