Which is true of case-based reasoning (CBR)?
DaniilM [7]

Answer:

The correct option is Option C: It matches a new problem with a previously solved problem and its solution.

Explanation:

Case-based reasoning (CBR) is used when someone tries to solve new problems based on old problems that were similar. The person applying case-based reasoning would look for the solutions to these similar past problems and try to apply them to the new case. For example, a doctor who tries to treat a patient based on what was successful with a prior patient with a similar problem is applying case-based reasoning. In some instances, these problems are available in a database and ideally, that is how it is conceived, but it would depend on the field and the kind of problems. There is no universal global network dedicated to CBR as a whole (other than generic searches on the internet in general). One example of a specific CBR database is the European Nuclear Preparedness system called PREPARE.
